Abstract

The invention discloses a preparation method of energy-saving environment-friendly building heat insulation paint, relates to the field of building materials, and mainly aims to solve the problems that traditional heat insulation paint is high in cost and can generate a lot of harmful volatile matters. The method mainly includes eight steps. According to the method, the production cost of the heatinsulation paint can be effectively reduced, raw materials are reasonably matched, the volatile content of harmful substances can be greatly reduced, current energy-saving environment-friendly development themes are met, and the heat insulation paint has wide market prospects and high practical values and is worthy of popularization and use.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of an energy-saving and environment-friendly building thermal insulation coating. Background technique [0002] Thermal insulation coating Thermal insulation coating is a new type of thermal insulation material. It is a kind of coating that achieves thermal insulation through low thermal conductivity and high thermal resistance. , light weight, convenient construction, long service life and so on. Insulation coatings can be widely used in construction, chemical industry, petroleum, electric power, metallurgy, shipbuilding, textile, storage, transportation, aerospace and other industries, mainly used for heat insulation or heat preservation (cold preservation). The coating has good adhesion , Easy construction, can be used on steel, cast iron, galvanized, aluminum, copper, magnesium, reinforced concrete, stone, wood, brick, ceramics, glass, textiles, plastic...
