Problems solved by technology

[0003] With the wide application of polyamide fibers, the industry has put forward higher requirements for these polyamide fiber products. The toughness and light resistance of polyamide fibers themselves are poor, and their retention is not good. The mechanical properties and corrosion resistance stability are obviously reduced, and these shortcomings affect the application of polyamide fiber materials to a certain extent

Abstract

The invention discloses a polyarmide fiber composite material. The polyarmide fiber composite material comprises polyarmide fibers, a modifier maleic anhydride grafted POE, chitosan modified montmorillonite, and a compatibilizer. The invention also discloses a preparation technology of the polyarmide fiber composite material. POE is grafted and modified by maleic anhydride, so the modified POE can be well fused with the polyarmide fibers and other raw material components, thereby the heat resistance temperature of the composite material is improved, the permanent deformation decreases, and the tensile strength, the tearing strength and other main performance performances are greatly improved; and the modified montmorillonite is used to well enhance the toughness of the polyarmide fibers, so the polyarmide fiber material with high performances and good comprehensive performances is obtained.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a high-performance polyamide fiber composite material and a preparation process thereof. Background technique [0002] Polyamide fiber (nylon / PA) is mainly used for synthetic fibers, which has good comprehensive properties, including mechanical properties, wear resistance, heat resistance, chemical resistance and self-lubricating properties, and has a low coefficient of friction. Flame retardant, easy to process. The most prominent advantage of polyamide fiber is that its wear resistance is higher than other fibers, 10 times higher than cotton fiber, 20 times higher than wool fiber, and when stretched to 3-6%, the elastic recovery rate can reach 100% %; Polyamide fiber has high strength and can withstand tens of thousands of times of bending without breaking, which is 1-2 times higher than cotton fiber, 4-5 times higher than wool fiber, and 3 times higher...
