Abstract

The invention discloses a manufacturing method of a carbon fiber grid cloth reinforced composite EPP foamed sheet and a product. The method is characterized by comprising: a. preparing materials: specifically, preparing the following thermoplastic PP foaming raw materials: 50-70 of high melt strength PP, 20-25 of ordinary PP, 8-15 of polyethylene, 6-10 of talc masterbatch, 0.1-0.3 of a main antioxidant, 0.1-0.5 of an auxiliary antioxidant, 0.6 of a heat stabilizer, 1-3 of color masterbatch, 0.3-0.4 of mineral oil, 5-10 of butane or CO2 gas, and 0.1-0.15 of glycerel monostearte; preparing the following thermoplastic PP bonding layer raw materials: 40 of copolymerized PP, 55 of ordinary PP, 0.2 of a main antioxidant, 0.4 of an auxiliary antioxidant, 0.6 of a heat stabilizer, 2.0 of color masterbatch, 0.1 of a light stabilizer, and 0.2 of mineral oil; b. mixing the materials; c. sending the thermoplastic foaming raw materials into an automatic feed hopper; d. extruding a foamed blank sheet, and compounding the blank sheet with carbon fiber grid cloth and PP non-woven fabric to obtain an EPP foamed composite board; and e. subjecting a PP bonded composite film blank and a composite material, an EPP foamed composite sheet together to impregnation and rolling to obtain a composite sheet finished product.

Description

technical field [0001] The invention relates to a manufacturing method and a product of an EPP foamed board, in particular to a manufacturing method and a product of a carbon fiber grid cloth reinforced composite EPP foamed board. Background technique [0002] As we all know, in order to achieve lightweight of automobiles, the first thing is to reduce the weight of auto parts. The lightweight of auto parts involves the lightweight of raw materials. Researchers at home and abroad have done a lot of research on the lightweight of automotive materials: using polypropylene foam materials to make automotive interior decoration top covers, pillars, door panels, etc.; using carbon fiber composite thermoplastic materials to make automotive shells, bottom guards, engine covers, etc. Wait. The development direction of automotive materials is to replace solid materials with foamed materials. Replacing aluminum plates and steel plates with carbon fiber and glass fiber reinforced comp...
