Problems solved by technology

At present, the vast majority of architectural coatings on the market are mainly based on the principle of barrier reflection. The performance is mainly based on reflection and heat insulation in summer, and the insulation effect of buildings in winter is not good.
The preparation of reflective heat insulation coatings usually uses hollow glass microspheres as heat insulation fillers. The quality and structure of the fillers have a great influence on the heat insulation performance of the product, and when mixed with titanium dioxide, it is easy to cause the reflection function of titanium dioxide to be limited, resulting in product failure. Erratic performance and reduced quality
Product performance is mainly based on reflective heat insulation in summer, poor heat preservation effect in winter, high cost, and thick coating

Abstract

The invention discloses building energy-saving thin-layer paint and a preparation method therefor. The building energy-saving thin-layer paint comprises the following raw materials in parts by weight: 16-30 parts of acrylic emulsion, 10-20 parts of a filler, 20-26 parts of barium sulfate, 1-5 parts of kaolin, 5-18 parts of titanium dioxide, 1-4 parts of dodecanol , 0.1-0.2 part of 2-methyl-4-isothiazolin-4-acetone, 0.1-0.4 part of 2-n-octyl-4-isothiazolin-3-acetone, 0.1-0.4 part of BASF A10, 0.1-0.5 part of sodium polyacrylate, 8-15 parts of sodium tripolyphosphate and 10-20 parts of water. The preparation method comprises: sampling in parts by weight, getting and mixing the filler, the barium sulfate, the kaolin and the titanium dioxide with water to obtain a mixture, adding sodium tripolyphosphate into the mixture, and stirring the mixture until the mixture is uniform; adding the acrylic emulsion and the dodecanol into the mixture, and stirring the mixture until the mixture is uniform; and adding the residual raw materials, and carrying out ball-milling on the residual raw materials, thereby obtaining the building energy-saving thin-layer paint. The building energy-saving thin-layer paint has the characteristics of good thermal insulation performance, low cost and a relatively thin coating.
