Hydrophobic silica aerogel modified acrylate emulsion coating

Abstract

The invention discloses a hydrophobic silica aerogel modified acrylate emulsion coating. The hydrophobic silica aerogel modified acrylate emulsion coating is prepared from, by weight, 100 parts of organic silicone modified acrylate emulsion, 10-25 parts of water-soluble alkyd resin, 10-25 parts of hydrophobic silica aerogel, 10-25 parts of pigment and filler, 3-10 parts of propylene glycol, 5-12 parts of n-caprylic alcohol, 3-8 parts of vinyl trimethoxy silane, 5-10 parts of cellulose nanocrystalline, 1-5 parts of sodium carboxymethylcellulose, 5-15 parts of film-forming agent, 2-5 parts of defoaming agent, 0.5-1.5 parts of sodium hexametaphosphate, 1-3 parts of benzotriazole, 1-2 parts of tributyl phosphate, 0.5-1.2 parts of triphenyl phosphate and 50-70 parts of deionized water. The hydrophobic silica aerogel modified acrylate emulsion coating is good in water resistance, weather resistance, thermal insulation and stain resistance and capable of meeting requirements of exterior wall coatings.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a hydrophobic silica airgel-modified acrylate emulsion coating. Background technique [0002] Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. [0003] The main function of the exterior wall latex paint is to decorate and protect the building surface, so that the appearance of the building is neat and beautiful, so as to achieve the purpose of beautifying the urban environment, and at the same time, it can protect the exterior wall of the building and prolong its service life. In addition, with the development of our society, a large number of buildings have emerged in various places, and the...

Problems solved by technology

Due to the sunlight, the temperature inside the building will increase with time, which will inevitably lead to an increase in energy consumption of the air conditioner

At the same time, temporary buildings such as factories and mobile houses mostly use metal roofs. Under the sunlight, the temperature rises rapidly, and the cooling effect of air conditioners is not good. It is necessary to use a high-efficiency thermal insulation coating to reduce the temperature of the building surface. a practical approach

However, the heat insulation of the existing latex paint cannot meet the needs, and the weather resistance is not very good in the process of long-term use, and it is prone to peeling and cracking
