Abstract

The invention discloses an environment-friendly flame-retardant polyurethane foaming material for a combined bumper and a preparation method of the polyurethane foaming material. The environment-friendly flame-retardant polyurethane foaming material for the combined bumper is prepared from the components of acetonitrile polyester and a mixture according to a mass ratio of 1:1.5, wherein the mixture comprises the following components in parts by mass: 50-55 parts of polyester 4110, 55-58 parts of polyether 982, 300-400 parts of glass fibers, 25-28 parts of polyether 403, 3.0-3.5 parts of silicone oil, 1.3-1.8 parts of a catalyst A33, 2.0-2.5 parts of a curing agent HP110, 3.5-4.0 parts of water and 38-42 parts of a flame retardant DMMP, wherein the silicone oil is silicone oil AK-8801. The preparation method comprises the following steps: adding the mixed components into a reactor to carry out a mixed reaction, stirring at the speed of 130-150 revolutions per minute for 4-5 hours so as to obtain the mixture; uniformly mixing the acetonitrile polyester and the mixture according to the mass ratio of 1:1.5, thereby obtaining the environment-friendly flame-retardant polyurethane foaming material for the combined bumper. With the adoption of the materials and the method, the prepared environment-friendly flame-retardant polyurethane foaming material for the combined bumper is flame-retardant, high-temperature-resistant, high in flame-retardant property, high in strength, long in service life and environmentally friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for a combined bumper and a preparation method thereof, belonging to the field of automobiles. Background technique [0002] At present, with the development of the automobile industry and the enhancement of people's awareness of safety and environmental protection, people's requirements for auto parts have also increased significantly. As a part of safety precautions, people have stricter requirements for bumpers. High temperature resistance, high flame retardancy, high strength, light weight, long service life, and high environmental protection characteristics. The strength of traditional bumpers usually cannot achieve ideal results. In the event of an accident, it is difficult to provide ideal protection for the body and people. Also, due to poor flame retardancy, the escape time of personnel is short, and there is a great potential safety hazard. . Therefo...
