Abstract

The invention belongs to the field of polymer materials, and particularly relates to an ultra-low temperature-resistant toughening material for injection molding-grade nylon and a preparation method of the toughening material. Raw materials of the ultra-low temperature-resistant toughening material comprise: in parts by weight, 70-80 parts of ethylene-propylene-diene monomer rubber, 20-30 parts ofethylene-octene copolymer, 5-10 parts of dibenzoyl peroxide, 0.5-2 parts of maleic anhydride, 1-5 parts of KT-1, 1-5 parts of carbon nanotubes, 0.05-0.3 part of solid initiator, 0.05-0.3 part of liquid initiator, 0.1-0.5 part of thermal stabilizer, 0.1-0.3 part of antioxidant and 10-20 parts of nylon 6. The prepared nylon toughening agent belongs to injection molding-grade toughening agents, anda step of reaction-extrusion of nylon toughened by a toughening agent is omitted, so that the production cost is saved effectively; secondly, the toughening material can be used in an environment withan ambient temperature of 50 DEG C below zero, so that low-temperature resistance of the toughened nylon is improved effectively, and the notched impact strength of the toughened nylon is improved.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a toughening material for ultra-low temperature resistant injection molding grade nylon and a preparation method thereof. Background technique

[0002] Nylon resin was the first resin developed by DuPont for the preparation of fibers. It was mass-produced in 1939; in the 1950s, it began to develop and produce injection-molded products to replace metals to meet the requirements of lightweight and cost-reducing downstream industrial products. Nylon itself has high mechanical strength, good toughness, outstanding fatigue resistance, good corrosion resistance and aging resistance, and the prepared samples have the advantages of light weight, easy dyeing, and easy molding; therefore, nylon is widely used to replace copper And other metals are used in machinery, chemical industry, instrumentation, automobile and other industries to manufacture bearings, gears, pump blades a...
