Abstract

The invention discloses a high-temperature-resistant nylon material. The high-temperature-resistant nylon material is prepared from, by weight, 0.8-1 part of 8-hydroxyquinoline, 180-200 parts of caprolactam, 3-5 parts of ammonium persulfate, 1-2 parts of zinc cyanurate, 2.6-4 parts of hydroxyl zinc stannate, 3-5 parts of triethanolamine, 2-4 parts of stearic acid and 0.01-0.02 part of a catalyst.An ester amine modified polymer is added into dimethyl carbonate solution containing 8-hydroxyquinoline and bisphenol A to obtain a finished product material through quaternarization, and the finishedproduct material is excellent in antibacterial performance and high temperature resistance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a high-temperature-resistant 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, 4-5 times higher than that of wool, and 3 times that of viscose fiber. However, polyamide fibers have poor heat resistance and light resistance, and poor retention. Therefore, the purpose of the present invention is to provide a high temperature resistant nylon material. ...
