Abstract

The invention discloses a weather-resistant building outer wall surface water-based coating material and a preparation method thereof. The weather-resistant building outer wall surface water-based coating material is prepared from the following raw materials: 25 to 30 parts of deionized water, 10 to 15 parts of vinylidene fluoride, 5 to 10 parts of acrylic acid, 26 to 30 parts of a filler, 1 to 2 parts of a film forming aid, 0.1 to 0.2 part of a pH regulator, 0.3 to 1 part of a thickening agent, 0.1 to 0.2 part of an antibacterial agent and 0.1 to 0.2 part of a defoaming agent. According to the weather-resistant building outer wall surface water-based coating material, vinylidene fluoride and acrylic acid are adopted as base materials in a formula, so that the weather-resistant building outer wall surface water-based coating material has good weather resistance and good heat resistance and light resistance, and the service life of the weather-resistant building outer wall surface water-based coating material is prolonged to the maximum extent; and by further adding an antibacterial agent, the weather-resistant building outer wall surface water-based coating material also has an antibacterial effect, and can prevent the wall body from breeding bacteria.

Description

technical field [0001] The invention relates to the technical field of wall coatings, in particular to a weather-resistant water-based coating for exterior walls of buildings and a preparation method thereof. Background technique [0002] Paint, what we usually call paint is just one of them. Refers to a type of liquid or solid material that can form a thin film coated on the surface of an object under certain conditions to provide protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resin has replaced vegetable oil, so it is called paint. Coatings are not liquid. Powder coatings are a large category of coatings. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemica...
