Abstract

The invention belongs to the technical field of lubricants, and in particular relates to a preparation method of a reinforcing and toughening lubricant specially used for ABS. The method comprises thefollowing steps: firstly nano powder is added into ethanol, a treating agent is added to modify the surface of the powder, the obtained treated nano powder is added into ethylenediamine to obtain aminated nano powder, the aminated nano powder and stearic acid are subjected to a reaction at high temperature to obtain a waxy substance, glass cellulose modified by glyceryl monostearate can be addedinto the waxy substance, extrusion granulation is performed, and therefore the reinforcing and toughening lubricant specially used for the ABS can be obtained. According to the method provided by theinvention, the prepared lubricant is added into the ABS resin, and the lubricant has good compatibility with the ABS resin, and improves the impact strength and bending strength of the ABS resin whileimproving the fluidity of the ABS resin.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a preparation method of a special reinforced and toughened lubricant for ABS. Background technique [0002] ABS resin is a mixture of three monomer copolymers of acrylonitrile, styrene and butadiene, including both acrylonitrile-styrene copolymer with good fluidity and polybutadiene rubber grafted with SAN resin . In order to better ensure the molding quality of ABS resin and adapt to the molding requirements of complex products such as large and thin walls, stearylamide and stearate lubricants are generally added to ABS resin, and polyethylene wax is also added to some ABS resin products. type of lubricant. The role of lubricants is to reduce the friction between polymer molecules and make it easier for macromolecules to slide, thereby reducing frictional heat generation and improving resin flow properties; second, forming a lubricating layer on the surface of p...
