Abstract

The invention relates to an ABS composition and a preparation method thereof. The ABS composition is prepared from the following raw materials in parts by weight: 98-102 parts of ABS resin, 5-50 partsof mesoporous masterbatch, 10-30 parts of a flame retardant, 1-10 parts of a flexibilizer and 0.1-2 parts of a processing aid. The mesoporous masterbatch is prepared from 50-99 parts of a vinyl aromatic hydrocarbon monomer, 1-50 parts of an unsaturated nitrile monomer, 1-40 parts of a solvent, 1-30 parts of a grafted elastomer, 0.001-0.1 part of an initiator, 0.01-0.08 part of a chain transfer agent and 5-20 parts of a mesoporous material through in-situ polymerization. The ABS composition has good flame retardance and mechanical properties.

Description

technical field [0001] The invention relates to the field of materials, in particular to an ABS composition and a preparation method thereof. Background technique [0002] ABS is a terpolymer of acrylonitrile, butadiene and styrene. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is widely used in machinery, automobiles, electronic appliances, and instruments. Instrumentation, construction and other industrial fields. ABS is a kind of polymer material with poor flame retardant performance. Its horizontal burning speed is fast, and it will continue to burn after leaving the fire. There are great safety hazards in actual use, which are potentially harmful to the lives and property safety of the masses. threaten. Especially now that electronic products tend to be thinner, the safety requirements for materials, especially the requirements for flame retardancy are more stringent. [0003] The pa...
