Prediction of the future development trend of interior wall paint and exterior wall paint

interior wall paint and exterior wall paint are two kinds of wall paint according to the use position on the building, and they are one of the main decorative materials used for the wall in decoration. Usually we call them wall paint

according to the statistical data of 1348 paint enterprises above Designated Size in 2009, the total annual output reached 7.5544 million tons (calculated by 9000 tons for 7 enterprises in Heilongjiang Province), which was 14.14% higher than that of 6.6188 million tons (calculated by 9732 tons for 8 enterprises in Heilongjiang Province in 2008) and had extensive business activities in this region before; The output of architectural coatings reached 2.6167 million tons, an increase of 21.19% year-on-year from 2.1592 million tons in the same period last year, and the growth rate exceeded the industry expectations. It can be seen that the rise of architectural coatings in China is very obvious, and the demand for wall coatings such as interior wall coatings and exterior wall coatings continues to rise with the economic recovery

in 2009, 2571 coating enterprises above national scale completed a total industrial output value of 183.591 billion yuan at current prices, an increase of 15.80% over 158.558 billion yuan in the same period in 2008; The current sales output value reached 179.128 billion yuan, up 15.20% from 155.505 billion yuan in the same period in 2008. From the growth rate of the two indicators, it is higher than the growth rate of output. It is worth noting that the export delivery value in 2009 was 7.506 billion yuan, down 46.4% from 14.017 billion yuan in the same period in 2008, with a significant negative growth. This shows that under the influence of the financial crisis, the paint industry, like China's overall export situation, is seriously hampered by exports, the export market continues to be volatile, and the export situation is facing a huge test

however, from the perspective of the completion of economic indicators of China's petroleum and chemical industry in 2009, the proportion of the coating industry in the current total industrial output value and main business income of the entire petrochemical industry in 2009 was 2.77% and 2.72% respectively, slightly higher than 2.40% and 2.34% in 2008. The overall profit of the petrochemical industry was 419.063 billion yuan, down 5.22% from 442.131 billion yuan in 2008; The total profit of 2558 coating manufacturers reached 11.353 billion yuan, up 35.73% from 8.364 billion yuan in 2008. The total profit and tax reached 16.980 billion yuan, up 33.53% from 12.716 billion yuan in 2008. It can be seen that the profits and tax amount of the coating manufacturing industry increased significantly in 2009

the above indicators can reflect that the overall operation quality of China's coating industry in 2009 has been improved to a certain extent, and the economic benefits have improved significantly

future development trend of interior wall coatings

the current market, technology, production and use of interior wall coatings will last for a period of time. The film-forming material will still be mainly styrene acrylic lotion, with a small amount of acetate acrylic and pure acrylic lotion

improve the performance of low-cost, high pigment volume concentration synthetic resin lotion coating

in fact, there is still more research work to be done in the technology of synthetic resin lotion coating. Regardless of the many problems existing in synthetic resin lotion exterior wall coatings and functional interior wall coatings, as far as decorative interior wall coatings are concerned, the formulation of synthetic resin lotion coatings with low cost and high pigment volume concentration, which are widely used at present, is very unreasonable in some small paint factories. Most of these formulas are obtained from raw material suppliers. There is such a problem, that is, in order to use more marketed materials in coatings, there may be factors that artificially and subjectively increase the amount of some materials. Although this kind of formula is unreasonable, it is also welcomed by users because it can be obtained free of charge. For example, the amount of synthetic resin lotion in some latex paint formulations is only 9%, while the cost of additives accounts for 35% or even higher of the formulation cost. Although the use of additives is very important for synthetic resin lotion coatings, if it exceeds a certain limit, it may go to the opposite of the problem. In addition to film-forming additives can improve the performance of latex paint, other additives can only improve the film performance of latex paint, but do not significantly improve the effect. In order to avoid delamination during storage, the viscosity of this kind of coating is often adjusted very high, so it has to be diluted with water during coating. However, due to the low dosage of lotion, a little poor control when adding water may cause the coating to be de powdered. Therefore, it is necessary to deepen the research on the formulation of low-cost interior wall emulsion paint with large quantity and wide range, so as to make it more reasonable. For example, without reducing the performance of the coating, reduce the use of additives in the coating and reduce the cost of the coating

another work that needs to be done for low-cost, high pigment volume concentration synthetic resin lotion coatings is to improve the film performance of this kind of coatings. For example, with low-cost coatings, some famous brand products have much better hand feel and texture than general brand products. Therefore, improving the decorative effect of this kind of paint is also a subject that needs to be studied

develop new interior wall coatings

interior wall coatings will mainly develop towards healthy and fine types. The so-called healthy type means that the coating itself has the functions of sterilization, mildew prevention and improving the living environment. For example, there are nano coating additives that can release negative ions into the air in the market, while nano inorganic coating additives with the functions of mildew prevention, sterilization and air purification have also been studied more, and some studies have achieved good results. The so-called fine type refers to the use of ultra-fine fillers to finely process the coating to obtain a coating with fine appearance, smooth hand feel and rich texture. In short, the development trend of interior wall coating is to improve the decorative effect of the coating and increase the function of the coating. At the same time, according to the needs of the market, people will also strive to research and develop some new coatings that can highlight characteristics, publicize personality and have obvious technical and economic performance advantages. For example, high-grade and multi-functional interior wall coatings called "three in one" (anti mildew, anti bacteria, anti cracking, stain resistance, etc.) or "four in one", organic-inorganic composite interior wall coatings that can reduce costs and maintain unchanged performance, low-cost emulsion paint with lime calcium powder as filler with carbon dioxide absorption function, etc. Reveal the maximum endurance level of the performance experimental machine

develop new organic-inorganic composite interior wall coatings

inorganic coatings have good natural resources and environmental protection advantages. The organic-inorganic composite exterior wall coating has been applied successfully. With the progress of science and technology, foreign countries and Taiwan have developed composite coatings that can be applied to plastic, wood and other substrates, which were considered unsuitable for inorganic coatings in the past. Similarly, it is also worth paying attention to compounding inorganic matrix and synthetic resin lotion organic matrix to prepare a new composite interior wall coating with better technical and economic comprehensive performance

the future development trend of exterior wall coating

with the progress of coating production technology, the quality of exterior wall coating has reached a very high level. Some exterior wall coatings can be used for more than 15 years, which can fully meet the requirements of exterior wall decoration. Its rich color and quality, as well as the cost of economic inspection of different parts of the sample, make the exterior wall coating widely used in decoration engineering

in terms of the world paint market, the annual growth rate of exterior wall paint is 7%, much higher than the average growth rate of 5% in the paint industry. In addition, from a regional perspective, exterior wall coatings are widely used in developed regions such as Europe, America and Japan, and exterior wall coating decoration in Thailand has also accounted for 50% of the total decoration market. At present, the annual growth rate of China's mainland market is about 15%. The use of exterior wall paint for building decoration has also been accepted by more and more places, while Beijing, Shanghai, Jiangsu and other local governments have more clearly stipulated that high-rise buildings must use exterior wall paint for decoration

in terms of the varieties of exterior wall coatings, high-tech functional emulsion paints such as high elastic emulsion paint to prevent and make up wall cracks, silicon acrylic paint with excellent hydrophobic and pollution resistance, and fluorocarbon paint with high weather resistance have increased rapidly in China recently

Experts in the coating industry believe that exterior wall coatings should be developed in the following aspects:

(1) develop high-performance exterior wall coatings with high weatherability, stain resistance and color retention performance, and improve the weatherability and stain resistance of water-based emulsion paint and the performance of solvent based exterior wall coatings

(2) due to cement shrinkage or improper construction, cracks, water seepage, water leakage and other phenomena will occur in the outer wall of the building. This problem has aroused widespread concern in the society. Now we should develop elastic waterproof wall coating products that integrate decoration, crack prevention, waterproof and other functions
