Abstract

The invention belongs to the technical field of plastic modification, and in particular relates to a transparent PP (Polypropylene) material for an automobile radiator and a preparation method of the material. The material comprises the following components in percentage by mass: 20-40% of homopolymerized PP, 20-50% of first copolymerized PP, 10-20% of second copolymerized PP, 8-25% of thermoplastic elastomer, 2-8% of polar modifying agent and 0.1-0.3% of antioxidant. The preparation method comprises steps of mixing, extruding and pelleting. The properties of the material provided by the invention can meet the use requirements, and the material is low in cost.

Description

technical field [0001] The invention belongs to the technical field of plastic modification, and in particular relates to a transparent PP material for an automobile water tank and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the five general-purpose plastics. Due to its rich source of raw materials, cheap price, easy processing and excellent product performance, it has a wide range of uses and has become the fastest-growing variety of general-purpose resins. It is widely used in In automotive interior and exterior trim, electronics and home appliances. Although polypropylene has many advantages, it also has some disadvantages. For example, it does not have a good balance between rigidity and toughness. High-modulus polypropylene often cannot achieve high impact at the same time, and high-impact polypropylene cannot simultaneously achieve high modulus. [0003] Therefore, the modulus of the material is usually increased by ad...
