Abstract

The invention discloses a mold material for injection molding of an automobile handle. The mold material is prepared from, by weight, 45-55 parts of polypropylene, 38-42 parts of polyurethane, 7-14 parts of epoxy resin, 6-10 parts of nano alumina, 10-12 parts of bamboo charcoal, 8-15 parts of pyrophosphate, 9-16 parts of fiber glass, 13-18 parts of methyl methacrylate, 12-14 parts of silicon micropowder, 9-16 parts of pure acrylic emulsion, 22-24 parts of melamine, 10-15 parts of benzoyl peroxide, 8-10 parts of tert-Butyl peroxybenzoate, 12-17 parts of carbon black, 9-16 parts of paraffin, 22-24 parts of di(butylcarbitol) adipate, 18-20 parts of silicon rubber and 13-18 parts of silicon dioxide. The mold material for injection molding of the automobile handle is high structural strength, resistant to low temperature and long in service life.

Description

technical field [0001] The invention relates to a mold material for injection molding of an automobile handle and a preparation method thereof. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. .Rubber injection molding: Rubber injection molding is a production method that injects rubber directly from the machine barrel into the model for vulcanization. The advantages of rubber injection molding are: although it is an intermittent op...
