Abstract

The invention provides a plastic liquid / powder / particle toughener and a processing method thereof. The plastic liquid toughener comprises 1 part of mixture, 6-8 parts of maleic anhydride, 4-6 parts of silane coupling agent, 3-5 parts of crosslinking agent, 2-5 parts of chain extender, 8-10 parts of methyl methacrylate, 2-3 parts of zinc stearate, 1 part of antioxidant, 1-5 parts of vitamin E, 2 parts of antifreezing agent, 5-8 parts of viscosity modifier, 2-5 parts of catalyst, 50-60 parts of dimethylbenzene, 40 parts of solvent oil, 5-8 parts of industrial alcohol, 6-8 parts of activating agent, 20-40 parts of silicon oil and 3-5 parts of hydroxy silicon oil. The mixture is composed of 25-30 wt% of SEBS (styrene-ethylene-butadiene-styrene), 25-30 wt% of UHMWPE (ultra-high-molecular-weight polyethylene), 10-15 wt% of butadiene emulsion and 35-40 wt% of POE (polyolefin elastomer).

Description

technical field [0001] The invention relates to the field of chemical products, in particular to a plastic liquid, powder or particle toughening agent and a processing method thereof. technical background [0002] Plastic has been widely used since its invention, and the toughness of plastic has always been a concern of people. Toughener is an additive added to resin to reduce the brittleness of plastic after hardening and improve its impact strength and elongation. Tougheners can be divided into rubber tougheners and thermoplastic elastomer tougheners: (1) Rubber tougheners. The types of tougheners mainly include liquid polysulfide rubber, liquid polybutadiene rubber, butadiene rubber, Nitrile rubber, ethylene propylene rubber and styrene-butadiene rubber, etc. (2) Thermoplastic elastomer Thermoplastic elastomer is a kind of synthetic material that exhibits rubber elasticity at room temperature and can be plasticized and molded at high temperature. Therefore, this type of...
