Abstract

The invention discloses a phenolic molding compound for forming automobile parts and a preparation method of the phenolic molding compound. The phenolic molding compound comprises the following components by weight: 20-35% of phenolic resin, 40-60% of an inorganic substrate, 8-12% of a filler, 2-5% of a curing agent, 0.1-0.2% of a mold release agent, 0.5-1.0% of a colorant, 0.2-0.3% of a surfactant and 0.3-0.5% of a toughening agent. The phenolic molding compound has greatly improved performance, can be fully melted and kneaded, and also meet requirements of environmental protection.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a phenolic molding compound used for molding automobile parts and a preparation method thereof. Background technique [0002] There are many parts on the car made of phenolic molding compound, such as: automatic window motor rack, brake booster, motor brush handle, etc. The basic requirements for phenolic molding compound parts for automobiles should have high mechanical strength, heat resistance, chemical resistance and dimensional stability. [0003] In order to meet the above performance requirements, the usual practice is to use novolac resin as the binder, glass fiber as the reinforcing material, and silicone rubber as the toughening agent. The phenolic resin is about 30 points, the glass fiber is about 30 points, and the mineral Filling is about 30 minutes, and other additives plus curing agent are about 10 minutes. With traditional mixing production, the prod...
