Problems solved by technology

The flame retardant ABS resin disclosed in the present invention can improve the impact performance and tensile performance of the flame retardant ABS resin while ensuring the 1.5mmV0 grade flame retardancy by optimizing the proportion of each component, thereby improving the comprehensive performance of the flame retardant ABS resin. Performance", which improves the impact performance and tensile performance of ABS resin by adding tougheners, but its tensile strength is 45MPa, and the impact strength is 20KJ / m 2 Left and right, it can be seen that the toughening agent used has a general effect on improving the performance of ABS resin and cannot meet the needs of the market.

Abstract

The invention discloses a preparation method of phosphate composite toughened ABS resin, and relates to the technical field of new materials. The preparation method comprises the following steps: (1)compounding of stearic acid / phosphate with white carbon black; (2) plastication treatment; and (3) melt extrusion. The limit oxygen index of the ABS resin prepared by the method disclosed by the invention is greatly improved; therefore, the flame retardant property of the ABS resin prepared by the method is greatly improved, the impact strength of the ABS resin prepared by the method is greatly improved, and the mass ratio of phosphate to stearic acid to phenolic resin has obvious influence on the impact strength of the ABS resin.

Description

Technical field [0001] The invention belongs to the technical field of new materials, in particular to a preparation method of phosphate ester composite toughened ABS resin. Background technique [0002] ABS resin is one of the polymers with the largest output and the most widely used. It organically unifies the various properties of PS, SAN and BS, and has excellent mechanical properties of toughness, rigidity, and rigidity. ABS is a terpolymer of acrylonitrile, butadiene and styrene. A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. [0003] ABS resin refers to acrylonitrile-butadiene-styrene copolymer. ABS is the acronym for Acrylonitrile Butadiene Styrene. It is a thermoplastic polymer material with high strength, good toughness and easy processing and molding. It is used to prepare various parts such as meters, electrical appliances, appliances, and machinery. [0004] Prior art "Application No. 201510705986.7, a flame-retardant ABS resin and a prep...
