Abstract

The invention discloses an environment-friendly flame-retardant foaming material for a lower bumper and a preparation method for the environment-friendly flame-retardant foaming material. The environment-friendly flame-retardant foaming material for the lower bumper consists of the following components in mass ratio of acetonitrile polyester to combined materials of 1 to 16; the combined materials is prepared from the following components in parts by mass: 40-50 parts of polyester CT 400, 300-380 parts of glass fibers, 35-40 parts of polyether, 2.8-3.2 parts of silicone oil, 1.8-2.5 parts of a catalyst D31, 1.0-1.5 parts of a catalyst A33, 3.5-3.8 parts of water and 38-42 parts of a flame retardant TCPP; and the silicone oil is silicone oil AK-8806. The raw materials are reasonably proportioned, so that the prepared foaming material is good in flame resistance and stability; and the bumper manufactured by the foaming material is high in fireproof safety and strength, and is low in service life; and the foaming material prepared from the environment-friendly raw materials which are reasonably proportioned does not release harmful substances, so that harm on environment and human body are avoided.

Description

technical field [0001] The invention relates to an environmentally friendly flame-retardant foaming material for a low 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 the characteristics of automobile parts have 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...
