Modified polypropylene material and preparation method thereof

Abstract

The invention discloses a modified polypropylene material. The modified polypropylene material comprises, by weight, 80-140 parts of polypropylene, 30-40 parts of a styrene-butadiene-styrene block polymer, 20-30 parts of polyurethane resin, 5-10 parts of hydroxyl-terminated hyperbranched polyester, 8-15 parts of chlorinated polyethylene, 1-2 parts of iron powder, 3-8 parts of fluorosilicone oil and 1-3 parts of an antioxidant. The polyurethane resin and the hydroxyl-terminated hyperbranched polyester added to raw materials are blended with the polypropylene and the styrene-butadiene-styrene block polymer to make the modified polypropylene material have improved wear resistance, ageing resistance and toughness, and the addition of the chlorinated polyethylene and the iron powder makes the modified polypropylene material have good sound insulation performance, so the modified polypropylene material can be used in the building field as a sound insulation assisting material of doors and windows, and the use of the modified polypropylene material is developed.

Description

technical field [0001] The invention relates to the field of vapor polymer materials and their molding and processing. More specifically, the present invention relates to a modified polypropylene material and its preparation method. Background technique [0002] Polypropylene plastic products have been widely used in chemical industry, construction, light industry, automobile, home appliance, packaging and other industrial sectors. [0003] Ordinary polypropylene is non-toxic, odorless, low density, has good dielectric properties and high-frequency insulation and is not affected by humidity. It is suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common acids, alkalis and other organic materials Solvents have little effect on it and can be used for tableware, but it also has obvious disadvantages, such as becoming brittle at low temperatures, not wear-resistant, easy to age, and poor toughness. [0004] With the development of th...
