Abstract

The invention discloses a bumper environment-friendly polyurethane foaming material and a preparation method thereof. The bumper environment-friendly polyurethane foaming material is prepared from the following ingredients including acetonitrile polyester and composition materials according to a mass ratio of 1:1.5, wherein the composition materials are prepared from the following materials in parts by mass: 68 to 75 parts of polyether 4110, 30 to 35 parts of polyether 982, 250 to 300 parts of glass fiber, 12 to 18 parts of polyether 1500, 2.9 to 3.5 parts of silicon oil, 0.8 to 1.3 parts of catalysts A33, 0.6 to 1 parts of catalysts A1, 3.0 to 3.8 parts of water and 35 to 40 parts of fire retardants TCPP, wherein the silicon oil is silicon oil AK-8805. The composition material ingredients are added into a reaction kettle for mixed reaction; the stirring speed is 130 to 150 r / min; the stirring time is 4 to 5h; the composition material can be obtained; then, the acetonitrile polyester and the composition materials are uniformly mixed according to the mass ratio of 1:1.5; the bumper environment-friendly polyurethane foaming material can be obtained. By using the material and the method, the prepared bumper environment-friendly polyurethane foaming material has advantages of flame resistance, high-temperature resistance, good flame-resistant performance, high intensity, long service life and environment-friendly effect.

Description

technical field [0001] The invention relates to an environment-friendly polyurethane foam material for a 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. . Therefore, exploring polyurethan...
