Abstract

The invention discloses an environmentally-friendly antiflaming foaming material of a bumper and a preparation method. The environmentally-friendly antiflaming foaming material of the bumper is prepared from the following ingredients in parts by weight: 1 part of acetonitrile polyester and 1.8 parts of composite material, wherein the composite material is prepared from the following ingredients in parts by weight: 40-50 parts of polyether 403, 20-30 parts of polyether 635, 2.5-3 parts of silicone oil, 1.2-1.4 parts of catalyst HP300, 1-1.5 parts of catalyst HP224, 3.5-4.6 parts of water and 38-42 parts of fire retardant TCEP (Tris(2-carboxyethyl)phosphine). According to the environmentally-friendly antiflaming foaming material, a reasonable proportion is adopted for raw materials, and the prepared foaming material has good fire resistance and stability; in addition, the bumper prepared from the foaming material has high fire-proof safety and strength and long service life; the foaming material prepared from an environmentally-friendly raw material which adopts the reasonable proportion does not release harmful substances so as to prevent from harming environment and human bodies.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant foaming 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, 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, it is the goal that this field has...
