Abstract

The invention discloses a nano self-cleaning external wall paint and a production method thereof, relating to the technical field of chemical industry. The nano self-cleaning external wall paint comprises the following components in percentage by weight: 50-55% of nano silicon resin, 15-18% of titanium white, 13-16% of ultrafine coarse whiting powder, 2-2.5% of C12 alcohol ester, 0.3-1% of sodium polycarboxylate, 0.3-1% of polyether modified siloxane, 0.6-0.8% of 2-(2-hydroxy-3,5-ditert-butyl)-5-benzotriazole chloride, 0.2-0.3% of polyoxyethylene fatty acid ester, 0.5-1% of polyacrylate, 0.1-0.2% of 1,2-benzothiazolinyl-3-one, 0.8-1% of 2-(4-thiazolyl)benzimidazole and the balance of water. The invention can solve the problems of poor pollution resistance, high pollution tendency and dissatisfactory heat insulation effect in the coating.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a self-cleaning exterior wall paint and a production method thereof. Background technique [0002] At present, buildings are mainly constructed of concrete and brick walls, and the surface of this structure is relatively rough. People usually use paint to decorate it. In addition, this structure has a wide range of light absorption, large heat storage, and slow heat dissipation, resulting in Fast heating and long duration of high temperature. In order to beautify the exterior wall and at the same time achieve a certain heat insulation effect, when people use paint to decorate the exterior wall of a building, they must consider both the stain resistance and aging resistance of the coating and the insulation of the decorative coating. heat effect. However, the coatings currently used are easy to be polluted by dust and lose their beautifying effect soon after the exteri...
