Problems solved by technology

[0002] At present, matte film is more and more subject to people's welcome, and matte film is generally coated with a layer of matte oil on the film surface, but the matte oil that adopts in the prior art generally all exists not to resist ethyl acetate, acetone , alcohol and other organic solvents, the adhesion between the oil layer and the film is poor, which in turn leads to poor scratch resistance, which in turn affects the application of matte films

preparation example Construction

[0032] The embodiment of the present invention also provides a method for preparing matte oil, which includes the following steps: mixing silicone-modified polyester, hydroxyacrylic polyester, aluminum silicate, and cellulose acetate butyrate to form the first component, and preparing The first component also includes mixing the leveling agent, ethyl acetate, dispersant and n-propyl acetate, and adding them separately to facilitate the uniform mixing of each material.

[0033] The mixing and dispersing time of the first component is 45-65 minutes, the rotating speed of mixing and dispersing is 800-1200 rpm, and the fineness of the first component is less than or equal to 10 microns; using the above conditions, it can ensure that each material is mixed more accurately Uniformity is more conducive to ensuring the coating of matte oil, and then ensuring the performance of matte oil.

[0034] Further, the matting aid and polytetrafluoroethylene wax are mixed to form the second com...

Abstract

The invention relates to the field of matte oil, in particular to a matte oil, its preparation method and application, and an anti-scratch matte film. Its raw materials include the first component, the second component and the third component; by weight, the first component includes 33-37 parts of silicone modified polyester, 33-41 parts of hydroxyl acrylic polyester, 8-10 parts of aluminum silicate and 0.5-1.2 parts of cellulose acetate butyrate; the second component includes 0.5-1.5 parts of polytetrafluoroethylene wax and 1.5-3 parts of matting aid; the third component includes 8‑10 parts of isocyanate. Through the interaction of silicone-modified polyester, hydroxyacrylic polyester, aluminum silicate, cellulose acetate butyrate, polytetrafluoroethylene wax, isocyanate, and matting additives, the matte oil has low-pressure light properties and good scratch resistance. Performance, chemical resistance, friction resistance and chemical resistance.
