Abstract

The invention discloses an impact-resisting toughening PP / PBT plastic alloy material. The material is prepared from, by weight, 55-80 parts of polypropylene, 20-40 parts of polybutylene terephthalate, 8-23 parts of polytetrahydrofuran, 15-28 parts of acetoacetic acid allyl ester, 10-30 parts of acrylic elastomer, 5-15 parts of antioxidants, 5-18 parts of toughening agents and 10-35 parts of talcum powder. The invention further discloses a preparation method of the impact-resisting toughened PP / PBT plastic alloy material. The prepared impact-resisting toughened PP / PBT plastic alloy material has the good impact resistance and toughening performance, and the application range of the PP / PBT plastic alloy material can be widened.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an impact-resistant and toughened PP / PBT plastic alloy material and a preparation method thereof. Background technique [0002] PP, polypropylene, is a semi-crystalline material. It is hard, has a high melting point, has good impact resistance, and has excellent resistance to moisture absorption, acid and alkali corrosion, and solubility. PP also has the disadvantages of high low temperature brittleness, poor aging resistance and poor dimensional stability. [0003] PBT, polybutylene terephthalate, is a thermoplastic engineering plastic with excellent performance. Because PBT has heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption, and good gloss, it is widely used in electronic appliances, auto parts, machinery, household products, etc., and PBT products are also compatible with PPS, PC, POM, PA, etc. are called the fiv...
