Problems solved by technology

[0004] In recent years, there has been a lot of research on water-based thermal insulation coatings in China, and many invention patents have been declared. However, the research on related thermal insulation coatings generally has problems such as single thermal insulation form and unsatisfactory thermal insulation effect.
The patent No. is 99114454.6 water-based anti-radiation heat-insulating coating, mainly anti-radiation, because it is a single-layer coating, so the heat-insulating effect is relatively poor; The manufacturing method and the water-based epoxy-modified acrylic heat-reflective heat-insulating coating with the patent application number 03111863.1 are mainly reflective, and their reflectivity is only 50-80%. thermal performance is limited by
In addition, the manufacturing method of the former is also relatively complicated, which is not conducive to popularization.

Abstract

Water thermal insulating reflection coating consists of base coat and face coat. The components comprises polymer emulsion, deionized water, thermal insulating material(or reflector material), coating filler and assistants. Its reflectivity can reach 83.5-92.5% and its thermal-radiant ratio can reach 91%. It achieves good radiation, resource saving and better thermal insulating reflection effect.

Description

Technical field: [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based heat-insulating and reflective coating. Background technique: [0002] At present, domestic grain and oil warehouses (including concrete structures, steel plate structures), industrial warehouses, storage tanks and pipeline surfaces in chemical, petroleum, and food industries, and partitions of buildings such as factories, modern farms, freezers, private houses, and office buildings Thermal cooling and exterior wall decoration mostly adopt traditional heat insulation methods: for example, for steel silos, silver powder paint is usually used for painting, but silver powder paint has poor heat insulation performance. Water spray cooling treatment not only requires high water and electricity costs, but also consumes a lot of water and electricity energy. At the same time, it will also affect the surrounding environment and the daily maintenance and maint...
