| abstract |
The invention provides a chlorinated rubber topcoat, comprising the following raw materials in parts by mass: 30-40 parts of chlorinated rubber, 10-20 parts of metal salt, 10-20 parts of alkyd resin, 0.2-0.8 part of drier; Acid resins are formed by polycondensation of polyols, vegetable oils, and polybasic acids including 1,3,5- trimellitic acid or its derivatives. The mass percentage is not less than 85%. 1,3,5-Mellitic acid or its derivatives have good metal complexation, and can convert metal salts into solid metal complex particles through complexation, which can be dispersed in the paint in a regular and orderly manner, thereby The paint has high solid content and good dispersibility and dispersion stability. In the chlorinated rubber topcoat provided by the present invention, the solid particles have good compatibility with the paint. |
