Abstract

The invention belongs to technical field of modification of high molecular materials and the technical field of processing, and discloses a glass fiber-reinforced polypropylene foaming material and a preparation method and an application thereof. The material comprises the following components in parts by weight: 35-80 parts of polypropylene, 1-10 parts of a toughening agent, 1-10 parts of a compatilizer, 0.2-0.4 part of an antioxidant and 15-45 parts of glass fibers. The preparation method of the material comprises the following steps of: putting the raw materials into a high-speed mixing machine according to the parts by weight for mixing for 3-5 minutes, adding into an extruder, adding 15-45 parts of glass fibers into a dual-screw extruder from a fiber inlet for extruding, and pelletizing to obtain a needed glass fiber-reinforced polypropylene material; and injecting a supercritical fluid into the glass fiber-reinforced polypropylene material molten at the homogenizing section of a screw rod of an injection molding machine to form a homogeneous solution, and injecting the homogeneous solution into an injection mold through injection molding to obtain a glass fiber-reinforced polypropylene foaming material. The material disclosed by the invention is a most suitable material for an engineering plastic marsh gas pond.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification and processing, and specifically relates to a glass fiber reinforced polypropylene micro-foaming material, a preparation method and an application thereof. Background technique [0002] Foam materials have the advantages of light weight, heat insulation, cushioning, insulation, anti-corrosion, and low price, so they are widely used in daily necessities, packaging, industry, agriculture, transportation, military industry, and aerospace industry. [0003] In addition to the characteristics of abundant raw material sources, light weight, and superior cost performance, polypropylene foam materials are also one of the most widely used and fastest growing resins in the world. [0004] Traditional polypropylene foaming methods can generally be divided into two methods: physical foaming and chemical foaming. When chemical foaming is used for foaming, on the one hand, the process con...
