Preparation method of matte varnish coating with alcohol friction resistance and high surface energy

Abstract

The invention relates to a preparation method of a matte varnish coating with alcohol friction resistance and high surface energy, and belongs to the technical field of high polymer materials. The matte varnish coating with alcohol friction resistance and high surface energy comprises the following components in parts by weight: 1-3 parts of dry vegetable oil, 1-3 parts of Fischer-Tropsch wax powder, 50-70 parts of varnish, 10-30 parts of matting powder, 1-10 parts of mineral oil, 5-20 parts of a friction-resistant agent and 1-3 parts of a surface leveling agent, polyethylene wax in the friction-resistant agent resists external abrasion and scratches, methacrylic acid is grafted, a lubricating layer is formed in the friction-resistant agent, friction is reduced, glossiness is improved, methacrylic acid is further compatible with matt varnish, alcohol friction resistance is enhanced, and high surface energy is given to the coating; the C-F bond energy of the polytetrafluoroethylene wax is high, and the polytetrafluoroethylene wax cooperates with the nano Al2O3, so that the alcohol friction resistance and the lubricity of the coating are improved; the matte varnish coating with alcohol friction resistance and high surface energy prepared by the invention not only has an excellent alcohol friction resistance effect, but also has good lubricity and high surface energy.
