Problems solved by technology

[0004] At present, the paint used as the finishing layer in the external insulation system of the building's external wall is a paint with ordinary elastic acrylic emulsion as the film-forming substance. The disadvantage of this paint is Yes: When the temperature difference between the external environment becomes large, the coating film of the facing layer will crack, which will cause cracking of the insulation layer, thereby affecting the service life of the entire insulation system of the building's outer wall; in addition, the coating formed by ordinary elastic acrylic emulsion The membrane has poor stain resistance and also affects the appearance of the building
Moreover, the existing thermal insulation coatings are mostly prepared by using conventional thermal insulation materials such as sepiolite, expanded perlite, expanded moon vermiculite, etc., because the coating is relatively thick, it is only suitable for insulation of pipelines, kettle bodies or buildings, etc. Thermal insulation, not suitable for exterior wall finishes of buildings

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a novel energy-saving and heat-insulating coating for walls and a preparation method thereof. Background technique [0002] Buildings are large energy consumers. Under the current situation of energy shortage, it is imminent to save energy and reduce consumption. At present, my country is in the peak period of housing construction. In 2003, the completed area of ​​urban and rural buildings reached 2.03 billion m 2 (of which 1.27 billion m 2 ), these buildings will consume a lot of energy in heating, air conditioning, ventilation, cooking, lighting, hot water supply, etc. during the period of decades to nearly a hundred years of use. But so far, there are about 40 billion m 2 (of which the city is about 14 billion m 2 ) buildings, only in the city's 320 million m 2 Houses can be regarded as energy-saving buildings, and other buildings are high-energy-consuming bu...
