Abstract

The invention belongs to the technical field of building coatings, and particularly relates to a building environment-friendly thermosetting acrylic coating and a preparation method thereof, and the building environment-friendly thermosetting acrylic coating comprises the following raw materials: acrylic acid, methyl acrylate, butyl acrylate, titanium dioxide, silicon dioxide, nano-silver, polydimethylsiloxane, a catalyst and an auxiliary agent. The preparation method of the environment-friendly thermosetting acrylic coating for the building comprises the following specific steps: S1, heating the raw materials; s2, mixing the raw materials. According to the scheme, polydimethylsiloxane is added and has a leveling effect, during use, the paint can be rapidly leveled, and the smoothness and flatness of the paint surface of the paint are improved; titanium dioxide, silicon dioxide and nano-silver are added, so that the wear-resistant effect and the toughness degree of a paint surface are remarkably improved, and a very good sterilization effect is achieved; through the matching effect of the raw materials, the environment-friendly effect is achieved, and the use of harmful components is reduced.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an architectural environmental protection thermosetting acrylic coating and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called architectural paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. [0003] When the existing architectural paint is used, it is easy to peel off, and the surface is not smooth enough, which affects the use effect. Cont...
