Formulation of coating: development of water-based elastic heat insulation and energy saving coating

Abstract: from the perspective of environmental protection and energy saving, this paper introduces the application, formulation process, raw material selection, performance index and application method of water-based elastic thermal insulation and energy saving coating, and emphatically discusses the determination and influence of each group's distribution ratio, so as to select the best ratio Key words: thermal insulation coating; water property; elasticity; energy conservation and environmental protection 0 Introduction The hot weather in summer will gather a lot of heat in the wall area The research of National University of Singapore found that the selection of materials is very important for the thermal conductivity of buildings, and plays a key role in building and wall insulation Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Abstract: from the perspective of environmental protection and energy conservation of coatings, this paper introduces the application, formulation process, raw material selection, performance index and application method of water-based elastic heat preservation and energy conservation coatings, and emphatically discusses the determination and influence of each group's distribution ratio, so as to select the optimal ratio Key words: heat preservation and insulation coating; water property; elasticity; energy conservation and environmental protection 0 · introduction the hot weather in summer will make the wall area gather a lot of heat The research of National University of Singapore found that the selection of materials is very important for the thermal conductivity of buildings, whether the walls are insulated or not, and the roof tiles also play an important role in the room temperature of the top floor In addition, the increasing energy consumption of air conditioning can not be ignored According to the analysis, 1% of the population growth will increase the energy consumption by 2.2%, and the power consumption will increase by 1.5% - 2.0% for each 0.6 ℃ increase of air conditioning temperature Thermal reflective insulation energy-saving material is one of the most competitive energy-saving methods Taking necessary building energy-saving measures can greatly reduce the energy consumption of building materials and air conditioning, enable modern people to obtain comfortable living environment on the premise of relatively economic and low energy consumption, and also enable more non renewable resources to be left to future generations, so it has far-reaching significance External wall insulation system has been widely considered as one of the most effective building energy-saving measures, but also to improve the weather environment, play a strong means of investment efficiency The external insulation of the external wall is to wrap the whole building with insulation materials, cut off the cold bridge, reduce the invasion of air and moisture, which has the double effects of heat preservation and insulation, and also plays a certain role in protecting the building structure However, the traditional external insulation system, such as polyphenylene granule mortar, EPS board and XPS board system, is cumbersome in construction, high in cost, easy to crack, and has some problems in insulation effect Therefore, a new type of high-efficiency thermal insulation coating, water-based elastic thermal insulation and energy-saving coating, has been developed, which is easy to construct, weather resistant, pollution resistant, decorative, energy-saving and environmental friendly, and has a broad application prospect 1 Development of waterborne elastomeric thermal insulation and energy saving coatings 1.1 experimental part 1.1.1 test material waterborne emulsion: AC-261C, AC-261p, pure acrylic acid rigid emulsion, 2468 elastic pure acrylic emulsion, Dow;
