Problems solved by technology

According to statistics, building energy consumption accounts for a large proportion of the entire energy consumption, and most of it is energy consumption in heating and cooling. As an important part of building energy conservation, thermal insulation coatings have become a hot topic in industry research. It has been paid attention to by countries all over the world. However, the thermal insulation effect of existing coatings is still poor and cannot meet people's needs.

Abstract

The invention discloses a thermal coating special for a building exterior wall. The thermal coating is prepared from, by weight, 20-30 parts of acrylic emulsion, 15-25 parts of novolac epoxy, 12-18 parts of modified talc powder, 4-9 parts of attapulgite, 5-11 parts of titanium dioxide, 3-7 parts of hollow glass beads, 6-10 parts of silicon dioxide gel, 2-4 parts of nano titanium dioxide, 1-3 partsof lignocellulose, 2-3 parts of dispersing agent, 1-4 parts of coalescing agent and 30-40 parts of deionized water. The thermal coating is excellent in performance, saves energy and protects the environment, can form effective protection on the surface of a coated base material, and is high in decoration property, low in energy consumption, resistant to fire and combustion, capable of insulatingand preserving heat and long in service life.

Description

[0001] technical field [0002] The invention belongs to the technical field of energy-saving products, and in particular relates to a special thermal insulation coating for building exterior walls and a preparation method thereof. Background technique [0003] Making buildings thermally insulated can not only save energy, but also improve the quality of living. According to statistics, building energy consumption accounts for a large proportion of the entire energy consumption, and most of it is energy consumption in heating and cooling. As an important part of building energy conservation, thermal insulation coatings have become a hot topic in industry research. Received the attention of countries all over the world, yet, the insulation effect of existing coating is still relatively poor, can not satisfy people's needs. Contents of the invention [0004] The invention provides a thermal insulation coating for building exterior walls and a preparation method thereof, ...
