Problems solved by technology

[0002] The sun is crucial to human production and life, but strong solar radiation will also bring a lot of inconvenience to our daily life and industrial production
For example: in a hot environment, the temperature of the outer wall and roof of the building will rise rapidly, which will lead to a sharp increase in the indoor temperature and affect the comfort of living; the internal temperature of objects such as metal storage tanks will also increase with the The surface temperature rises sharply, and when it reaches a certain value, there may be a danger of explosion; in addition, strong solar radiation will also bring a lot of inconvenience to our food storage and transportation.
In order to reduce the ambient temperature inside the object, the energy consumption of refrigeration and cooling equipment such as air conditioners and sprinklers will inevitably increase, which will lead to the serious problem of global warming

Abstract

The invention relates to a solar heat reflection heat-insulation thin film and a preparation method thereof. The heat-insulation thin film mainly takes polyvinyl chloride as a base material; the thinfilm has excellent solar heat reflection performance through adding rutile type titanium dioxide with high reflectivity and high covering power; precipitated barium sulfate, talcum powder, ultrafine calcium powder and kaolin are matched with the rutile type titanium dioxide according to a certain ratio to use; when the solar heat reflection performance of a whole filler system is improved, the cost of the filler system also can be reduced. The base material, filler and an auxiliary material are mixed and stirred in a high-speed dispersion machine for certain time, and then a mixture is added into a double-roller mixing machine and is subjected to open mixing and processing; finally, the material is subjected to calendaring treatment by adopting a calendering machine to prepare the solar heat reflection heat-insulation thin film. By adopting the solar heat reflection heat-insulation thin film, high-value application of the polyvinyl chloride is effectively realized; the prepared solar heat reflection heat-insulation thin film has good comprehensive performance, a preparation technology is simple and the production cost is low.
