Flame retardant composite material with high flow and preparation method

Abstract

The invention provides a flame retardant composite material with high flow and a preparation method. The invention aims to improve the machining performance of the composite material, so that the composite material has the high tenacity, high environmental-friendly flame retardance and high flow. The invention adopts the technical scheme that the composite material comprises the following components in part by mass: 60 to 70 parts of polrvinyl chloride, 20 to 30 parts of butadiene-acrylonitrile-styrene, 1 to 5 parts of styrene-butadiene-styrene, 1 to 3 parts of chlorinated polyethylene, 1.0 to 2.0 parts of heat stabilizer, 5 to 8 parts of plasticizer, 0.5 to 1.5 parts of lubricating agent, 0.5 to 1.0 part of PVC self-plasticizer and 0.3 to 0.5 part of intensifier. A small amount of chemically-modified PVC self-plasticizer is added into the composite material, so the machining performance of the composite material is improved, the plasticizing degree and mechanical property of the material are improved, and the self-plastification effect of the material is realized.

Description

technical field [0001] The invention relates to materials, in particular to a flame-retardant high-flow composite material and a preparation method thereof. Background technique [0002] my country started late in the development of flame-retardant ABS composite materials. Around the 1990s, my country's Shanghai Gaoqiao Petrochemical Company, Qingdao Institute of Chemical Technology, Guangzhou Institute of Synthetic Materials and other scientific research units, colleges and universities, and ABS manufacturers have all carried out research and development work, but the main development content is for The flame retardancy, thermal stability, and improvement of physical and mechanical properties of flame-retardant ABS are carried out by adding the third unit polymer modification and so on. Although the above research has made some progress in flame retardancy and thermal stability, it has not resolved the contradiction between the physical and mechanical properties of this typ...

AI Technical Summary

Problems solved by technology

[0004] ABS / PVC alloy has high impact strength, good thermal stability, flame retardancy and ideal cost / performance index. With the continuous development of science and technology, people have higher and higher requirements for the performance of materials. ABS Defects of / PVC alloy itself, such as: not too high bending strength, low thermal deformation temperature, unsatisfactory appearance, poor processing fluidity, etc. limit its development

It can be seen that the existing problems of the prior art are that processing performance, toughness and fluidity are not enough
