Abstract

The invention discloses a transparent nylon material, which is prepared from the following raw materials in parts by weight: 130-150 parts of nylon 1012, 1-2 parts of polybenzimidazole, 0.1-0.3 part of stannous sulfide, 7-9 parts of trimethylolpropane, 5-6 parts of carbonic acid, 0.01-0.02 part of a catalyst, 18-25 parts of 1, 6-hexanediol, 4-7 parts of fumed silica, 0.6-1 part of polysorbate and30-40 parts of trimethylene carbonate. According to the invention, by modifying with high-strength polycarbonate, the composite material is high in quality and wide in application field.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a transparent nylon material and a preparation method thereof. Background technique [0002] Polyamide is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can Greatly improve its wear resistance; when stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of times of bending without breaking; the strength of polyamide fiber is 1-2 times higher than that of cotton, Wool is 4-5 times higher than viscose fiber. However, the heat resistance and light resistance of polyamide fiber are poor, and the retention is not good, and the clothes made of it are not as crisp as polyester. In addition, both nylon-66 and nylon-6 used for clothing have the disadvant...
