Abstract

The invention discloses a composite coating and application thereof, and belongs to the technical field of coatings. The composite coating comprises a base material treating agent and a silica gel coating, wherein the raw materials of the base material treating agent comprise a coarsening agent and amorphous polyester, and the silica gel coating comprises the following raw materials: siloxane, silanol, a solvent and an auxiliary agent. In the invention, the base material treating agent is matched with the silica gel coating, so that the adhesive force between the silica gel coating and a high-hardness base material can be improved physically and chemically.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a combined coating and its application. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for coatings. Traditional coatings are only required to protect products, and now they are also required to achieve functions such as aesthetics and comfortable feel. Silicone coatings are coatings that can meet the above requirements. In order to improve the aesthetics of the appearance, color paste or toner can be added to the silicone coating; in order to improve the hand feeling, silica matting powder can be added to the silicone coating. All in all, silicone coatings have obvious advantages over other types of coatings. [0003] However, silicone coating also has its disadvantages: when the application substrate of the silicone coating is metal or other materials with a Shore hardness greater than 80A, the a...
