Abstract

The invention relates to a high-toughness AES composite material. The AES composite material consists of the following components: 70 to 90 parts of AES, 3 to 5 parts of ASA, 10 to 20 parts of toughening agent, 16 to 20 parts of flame-retardant agent, 4 to 10 parts of synergistic flame-retardant agent, 0.1 to 0.5 part of antioxidant. The calcium silicate whiskers have a typical porous structure, can be catalyzed and expanded to form carbon, and can improve the flame-retardant performance of the AES composite material; the production cost of the calcium silicate whisker is far lower than that of the conventional synergistic flame-retardant agent zinc borate, antimony trioxide and the like, and the cost of the AES composite material can be reduced; and by adding MBS or POE, the toughness ofthe flame-retardant AES material can be improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-toughness AES composite material. Background technique [0002] AES is an engineering plastic with excellent comprehensive properties. It has good dimensional stability, good insulation, oil resistance, and good molding performance, but its low ignition point greatly limits the application of AES composite materials in the field of flame retardant materials. . [0003] How to improve the synergistic flame retardant performance and toughness of AES has always been a subject that ordinary skilled in the art is striving to achieve. Contents of the invention [0004] The purpose of the present invention is to provide a high-toughness AES composite material and its preparation method to solve the problem of low ignition point of AES in the prior art. [0005] The present invention is achieved through the following technical solutions: [0006] A high-toughness AE...
