Method for manufacturing automobile damper with polyurethane composite material

Belonging to the technical field of auto part manufacturing, the invention relates to a method for manufacturing an automobile damper with a polyurethane composite material. The method comprises: adding a component C catalyst into component A, and stirring them uniformly, then pouring them into the machine tank of a low pressure casting machine, and conducting thermal insulation; then adding component B and the above mixed solution into a low pressure machine and carrying out stirring, injecting the mixture into a damper die for foaming, then spraying a release agent, thus obtaining an automobile damper. The polyurethane composite material prepared in the invention has the advantages of low viscosity, good fluidity, fewer dark bubbles, wide foaming scope, and no need for heating before use. And the automobile damper product manufactured with the polyurethane composite material is characterized by light weight, good strength, good elasticity, good smooth finish, fewer dark bubbles, no shrinkage, easy processing, and good elasticity, thus being very popular with automobile manufacturers.
