Abstract

The invention discloses a preparation method of an inorganic hard film plastic material added with organosilicon. The process utilizes active organosilicon solutions such as methyltriethoxysilane, dimethyldiethoxysilane and ethyl orthosilicate Coating and modifying polyester plastic materials; aggregating raw materials such as butylated amino resin, methyl etherified amino resin, melamine phosphate, etc., heating and calcining in a horse boiling furnace, adding coupling agent, defoaming agent, and curing agent , toughening agent and other ingredients to improve the performance of the composite material, and then a composite plastic material is obtained after a series of operations such as film drawing solidification, surface activation treatment, coating, suspension leveling, drying and cooling. The prepared film plastic material has high transparency, heat resistance and corrosion resistance, and has good application prospects. At the same time, it also discloses the application of the film plastic material prepared by the preparation method in the fields of optical wear-resistant layer, heat-resistant anti-corrosion coating and the like.

Description

Technical field [0001] The invention relates to the technical field of plastic materials, in particular to a preparation method of an inorganic hard film plastic material added with organic silicon. Background technique [0002] Polyester plastic materials have the advantages of low density, impact resistance, easy processing and molding, and low price. Therefore, they have received increasing attention and are currently widely used in optical instruments, aviation, construction, and transportation. However, polyester plastic materials have poor weather resistance, low hardness, and scratch resistance. The surface is easily scratched during use, which reduces the transparency of the material and deteriorates the decorative effect, which limits its scope of use. Therefore, it is necessary to research and develop transparent and hard organic / inorganic hybrid materials in order to improve the abrasion resistance of polymer substrates while taking advantage of the superior transparen...
