Abstract

The invention discloses a heat insulation coating for a building and a preparation method of the heat insulation coating, and relates to the field of building materials. The heat insulation coating is prepared from the following raw materials in parts: 90 to 100 parts of styrene-acrylic emulsion, 55 to 65 parts of glass wool, 45 to 55 parts of short fiber, 40 to 45 parts of thermoplastic expanded hollow microspheres, 25 to 30 parts of nano aluminium silicate, 20 to 25 parts of nano calcium carbonate, 10 to 20 parts of nano titanium dioxide, 10 to 20 parts of a filler, 10 to 15 parts of an auxiliary and 150 to 180 parts of water. A coating film formed by the coating is good in heat insulation and preservation effect, high in bonding strength, difficult to crack and high in abrasion resistance; furthermore, the preparation method is scientific and simple; the energy consumption is greatly reduced; meanwhile, the heat insulation coating is free of pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building thermal insulation coating and a preparation method thereof. Background technique [0002] With the improvement of human's awareness of environmental protection, architectural coatings are developing from the past performance of protecting walls and decoration to multi-functional and green development. Building energy conservation has been paid more and more attention by the country in recent years. Thermal insulation coating is a very popular solution for building exterior wall thermal insulation in recent years. However, most of the exterior wall insulation materials currently on the market have their own shortcomings, such as easy cracking, relatively poor thermal insulation performance, complicated construction process and high price. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of building thermal insula...
