Abstract

The invention discloses a foaming injection material for automobile steering wheels. The foaming injection material for automobile steering wheels is prepared from the materials in parts by weight: 55-62 parts of polyurethane, 19-24 parts of ethylene-vinyl acetate copolymer, 8-16 parts of polypropylene, 22-25 parts of aromatic polycarbonate, 16-20 parts of sodium carbonate, 35-40 parts of difluorodifluoromethane, 6-8 parts of lauryl sodium sulfate, 11-14 parts of isocyanate, 23-25 parts of sodium ricinoleate, 17-20 parts of polyether glycol, 8-10 parts of sorbitol, 7-11 parts of mica powder, 23-24 parts of sodium pyrophosphate, 6-9 parts of ammonium polyphosphate, 11-14 parts of stearic acid, 13-16 parts of polyethylene polyamine, 2-4 parts of butadiene and 8-10 parts of silicon dioxide. The foaming injection material for automobile steering wheels has the advantages of favorable elasticity, light weight and favorable wear-resistant effect.

Description

technical field [0001] The invention relates to a foam injection molding material for an automobile steering wheel and a preparation method thereof. Background technique [0002] The earliest automobiles were driven by rudders. The severe vibration generated during the driving of the car is transmitted to the driver, which increases the difficulty of controlling the direction. After the engine was changed to be installed on the front of the car, due to the increase in weight, the driver had no way to use the rudder to drive the car. This new design of the steering wheel came into being. The gear system introduced between the driver and the wheels is flexible in operation, and it is well isolated from the severe vibration from the road. Not only that, but a good steering wheel system can also bring the driver a feeling of intimacy with the road. More than 120 years ago, the steering wheel that the inventor of the automobile placed on the steam automobile at first was insta...
