Problems solved by technology

The PP / ABS alloy modified by utilizing the advantages of PP and ABS can combine the advantages of both. The product has better rigidity and flexibility and lower shrinkage rate, and effectively reduces the surface resistivity of the product. However, PP and ABS The Vicat softening point of ABS itself is not high, so it is difficult to be used in occasions that require high heat resistance, and it is difficult to meet most application requirements due to the high surface resistivity of the material itself.

Abstract

The invention discloses an antistatic reinforced PP / ABS alloy material and a preparation method thereof. The antistatic reinforced PP / ABS alloy material comprises the following raw materials in parts by weight: 35-55 parts of PP, 15-30 parts of ABS, 2-5 parts of a compatilizer, 0.3-0.6 part of a coupling agent, 0.3-0.5 part of a compound antioxidant, 3-5 parts of a compound antistatic agent, 0.3-0.5 part of a lubricant and 15-30 parts of alkali-free glass fiber. The antistatic reinforced PP / ABS alloy material has the advantages of high heat-resistance temperature, low shrinking percentage, low surface impedance, good mechanical property, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of plastic alloy materials, in particular to an antistatic enhanced PP / ABS alloy material. Background technique [0002] PP (polypropylene) is a general-purpose plastic with excellent performance. It has the characteristics of good toughness, moderate strength, and light specific gravity. It is widely used in packaging, electronic appliances, and machinery manufacturing. Heat resistance is difficult to apply to the defect of harsh use environment. Secondly, ABS (acrylonitrile-butadiene-styrene copolymer) is an excellent polymer alloy with the advantages of high strength, adjustable toughness and low shrinkage. The PP / ABS alloy modified by utilizing the advantages of PP and ABS can combine the advantages of both. The product has better rigidity and flexibility and lower shrinkage rate, and effectively reduces the surface resistivity of the product. However, PP and ABS The Vicat softening point of ABS itself...
