Abstract

The invention discloses a heat insulation coating and a production method thereof. The heat insulation coating comprises 20-30 wt% of water, 35-40 wt% of perlite, 28-40 wt% of an acrylate emulsion, 2-3 wt% of a thickener, and the balance of a pigment. The heat insulation coating has the following advantages: 1, the coating is convenient to construct, can be directly applied to walls in a coating manner by using a roller, or can be directly sprayed on the walls by using a spray gun, or can be applied to the walls in a brushing manner by using a brush; and 2, the coating has the characteristicsof environmental protection, non-toxicity, low volatility, odorlessness and good heat insulation property.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a thermal insulation coating and a production method thereof. Background technique [0002] Coating is a building material with a long history. With the development of society, there are more and more types of coatings. According to reports, indoor coatings are mainly divided into two types: thermal insulation coatings and solvent-based coatings. The main source of pollution is solvent-based paint, and the use of environmentally friendly thermal insulation paint can completely eliminate the worry about paint pollution. Experts from the China Paint Industry Association believe that any solvent-based paint will contain 50% or more of organic solvents. Since most solvent-based paints and organic solvents contain benzene and its compounds, long-term exposure will cause serious harm to the human body. Therefore, more and more people like to choose environmentally friendly and n...
