Abstract

The invention discloses a polyurethane environment-friendly flame-retardant foaming material for a storage battery box body assembly and a preparation method thereof. The polyurethane environment-friendly flame-retardant foaming material for the storage battery box body assembly is composed of acetonitrile polyester and mixed material components in a mass ratio of 1:1.6, wherein the mixed material is composed of the following components in parts by mass: 25-35 parts of Liansheng polyester, 25-35 parts of polyether 4113, 20-35 parts of polyester 450, 2.5-3 parts of silicone oil, 180-250 parts of reinforcing glass fibers, 1.2-1.8 parts of a catalyst DMP-30, 1.3-1.7 parts of an equilibrium catalyst HP-12, 1.1-1.5 parts of a catalyst HP-54, 3.5-3.8 parts of water and 38-42 parts of a flame retardant, and the silicone oil is silicone oil AK-8807. The polyurethane environment-friendly flame-retardant foaming material disclosed by the invention has the advantages that the raw materials adopt a reasonable ratio, the obtained foaming material has good flame-retardant property and stability, and a bumper made from the foaming material not only has high fire protection security and strength but also is long in service life; and the foaming material prepared by adopting environment-friendly raw materials in the reasonable ratio can not release harmful substances, and no harm is caused to the environment and a human body.

Description

technical field [0001] The invention relates to a polyurethane environment-friendly flame-retardant foaming material for a storage battery box assembly 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 auto parts have increased significantly, and the battery box is even more indispensable. People have stricter requirements for it. It has the characteristics of high temperature resistance, high flame retardancy, high strength, light weight and high environmental protection. Traditional battery boxes usually cannot achieve ideal results. In the event of an accident, the poor flame retardancy often leads to short escape time for personnel, which poses a great safety hazard. Therefore, it is the goal that this field has been pursuing to e...
