Title:
HIGH-IMPREGNATION LONG GLASS FIBER REINFORCED POLYPROPYLENE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/000608
Kind Code:
A1
Abstract:
Disclosed are a high-impregnation long glass fiber reinforced polypropylene composite material and a preparation method therefor. Said material is composed of the following raw materials in parts by weight: 43.2-63.2 parts of polypropylene resin, 30-50 parts of glass fiber, 1-10 parts of a compatibilizer, 1-10 parts of a toughening agent, 0.1-1 part of an antioxidant, and 0.2-2 parts of a lubricant. After the glass fiber passes on-line through a glass fiber heating pre-dispersing device and a cooling device, same is electrified by silk friction, and finally passes through a static electricity generating device and directly enters a dipping tank for production. The present invention has the following technical effects: the high-impregnation long glass fiber reinforced polypropylene composite material of the present invention achieves each glass fiber being wrapped with polypropylene resin, which can protect the glass fibers from damage during plasticizing by pellets, thereby preserving the length of the glass fibers in products; moreover, the tensile strength, flexural modulus, impact strength and other properties thereof are greatly improved.
