Abstract

The invention discloses an automobile polyurethane combination material and a preparation method thereof. The technical problems of an automobile polyurethane material, such as pungent smell and die shrinkage after demoulding are solved. The invention belongs to the technical field of polyurethane materials. The polyurethane combination material is prepared by the steps of mixing and stirring a component A and a component B according to the mass ratio of 100-110: 28-50, wherein the component A comprises polyether polyol, polypolyols, a chain extender, a heuristic catalyst, a gel catalyst, a cell opener, silicone oil, a cross-linking agent and water; and the component B is modified MDI. According to the automobile polyurethane combination material, elongation of the product is enhanced, cell opening rate is increased, and the product is basically odor-free. The preparation method of the automobile polyurethane combination material is simple to operate and is more energy-saving and environmentally-friendly because there is no need to heat the raw materials during the production process.

Description

technical field [0001] The invention relates to the technical field of polyurethane materials, in particular to a polyurethane composite material for automobiles and a preparation method thereof. Background technique [0002] Polyurethane material is the abbreviation of polyurethane, and its English name is polyurethane, which is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. The product application fields involve light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation, etc. In the automotive field, such as car roof, bumper, interior trim (steering wheel, instrument panel), etc. are widely used. However, the existing polyurethane materials for automobiles generally have a pungent odor, and also have defec...
