Abstract

The invention discloses fluorine / silicon-containing silicon paint. The fluorine / silicon-containing silicon pain is prepared from the following components in parts by weight: 10 to 80 parts of fluorine-containing acrylate monomer, 9 to 60 parts of acrylate monomer, 5 to 30 parts of silane coupling agent, 2 to 28 parts of polysiloxane, 0.2 to 1.8 parts of initiator, and 40 to 80 parts of solvent. The organic fluorine and organic silicon are simultaneously used for modifying acrylate resin to obtain the fluorine / silicon-containing polymer which takes silicon oxygen bond as a main chain and fluorine-containing group as a side chain, and while keeping the heat resistance and cold resistance of the organic silicon material, the polymer also has the excellent performance such as weather resistance, aging resistance, solvent resistance, oil resistance and has lower surface energy. The product provided by the invention is suitable for various fields such as spaceflight, ocean, metal base materials, cultural relics, glass, ceramics, electronic products.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fluorine-containing silicon coating and a preparation method thereof. Background technique [0002] Coating is a material that can be coated on the surface of the object to be protected or decorated by different construction techniques, and can form a continuous film firmly attached to the object to be coated, usually in the form of resin, oil, or emulsion Mainly, add or not add pigments, fillers, add corresponding additives, and use organic solvents or water to prepare viscous liquids. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. [0003] Acrylate-based coatings use acrylic acid or methacrylate as the main monomer. They are widely used as coating matrix materials. They have excellent film-forming properties, light resistance, oil resistance, mechanical stability and adhesion. The source of raw materials is abundant. ...
