High inflaming retarding abrasion resistance PP/ABS composite material and preparation method thereof

Abstract

The invention relates to a PP/ABS composite material, and in particular relates to a high inflaming retarding abrasion resistance PP/ABS composite material and a preparation method thereof; the cashew nut shell oil friction powder is used for modifying PP for increasing the abrasion resistance performance, tin antimony oxide is used for modifying ABS, performance of the modified master batch is changed, modified PP, ABS master batch are mixed for preparing particles through crosslinking, expanded graphite micro powder is used for loading fire retardant triphenyl phosphate which can be evenly dispersed in the master batch, thus even and high effect flame retardant efficiency can be obtained; finished composite material prepared by the method effectively combines the advantages of the PP and ABS, has excellent inflaming retarding, abrasion resistance and anti-static electricity effect, and the market competitiveness is greatly improved.

Description

Technical field [0001] The invention relates to a PP / ABS composite material, in particular to a high flame-retardant and wear-resistant PP / ABS composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a non-toxic, odorless, and tasteless milky white highly crystalline polymer with good comprehensive properties and a wide range of applications. However, its biggest shortcomings are low temperature brittleness, low heat distortion temperature, large shrinkage, Shortcomings such as high product defect rate restrict the promotion and application of PP products. In order to improve the performance of PP materials, they are often modified. Acrylonitrile-butadiene-styrene copolymer (ABS) has the advantages of heat resistance, impact resistance, high hardness, and good dimensional stability. It is often used in PP modification treatment. [0003] PP / ABS composite flame-retardant materials are relatively common, but traditional products mostl...

Problems solved by technology

[0003] PP / ABS composite flame retardant materials are relatively common. However, traditional products often add flame retardants directly during the preparation process, resulting in low and uneven flame retardant effects of materials, resulting in waste of resources, and due to the solubility of PP and ABS The parameters vary greatly, and the comprehensive mechanical properties of composite materials are often unsatisfactory. Therefore, in order to obtain high-efficiency and high-quality PP / ABS composite flame-retardant materials, it is necessary to start from the process and formula, improve the modification efficiency, and further improve the PP / ABS The performance of ABS composite materials
