Abstract

The invention discloses a nylon composite material and a preparation method thereof. The problems of poor strength and poor toughness of existing pure nylon are solved. The nylon composite material comprises, by mass, 20-30 parts of PA66, 25-30 parts of PA6, 50 parts of chopped glass fibers, 0.3-0.5 part of a lubricant TAF, 0.3-0.5 part of EBS, 0.3-0.5 part of an antioxidant 1098 and 5-10 parts ofa processing assistant; and the processing assistant is one or two or more of high-viscosity PA66, a flexibilizer and an impact modifier. The preparation method comprises the following steps: 1, uniformly stirring the lubricant TAF, EBS, the antioxidant 1098 and the processing assistant to obtain a mixed assistant; 2, uniformly mixing the PA66 with the PA6, adding the mixed assistant A, and performing uniform stirring to obtain a mixed raw material; 3, feeding the mixed raw material and the chopped glass fibers into a double screw extruder; and 4, performing melt extrusion, and pelletizing the obtained material to obtain nylon composite particles. The toughness and the strength of the nylon are improved.

Description

technical field [0001] The invention relates to polymer materials, in particular to a nylon composite material and a preparation method thereof. Background technique [0002] The slow falling device of the cover plate has been widely used on the toilet. The existence of the slow-falling device slows down the falling speed of the cover during the falling process, so as to prevent the cover from falling heavily on the toilet body and generating a lot of noise. The slow falling device is generally provided with a rotating mechanism that rotates with the cover plate. All are made of nylon at existing slow falling device. Nylon is a common name for polyamide, a general term for polymers containing amide groups in the repeating unit of the main chain of the macromolecule. Polyamides can be prepared by ring-opening polymerization of lactams, or by polycondensation of diamines and dibasic acids. Polyamide (PA) refers to a polymer whose main chain contains polar amide groups (-CO...
