Abstract

The invention discloses an environmental-friendly flame-retardant polyurethane foaming material for an upright post and a preparation method of the environmental-friendly flame-retardant polyurethane foaming material. The environmental-friendly flame-retardant polyurethane foaming material for the upright post is composed of the following components by mass: a ratio of acetonitrile polyester to a mixture is 1:1.5; the mixture comprises the following components in parts by mass: 55-75 parts of polyether 330, 35-45 parts of polyester 3628, 25-28 parts of polyester 403, 280-350 parts of glass fiber cloth, 400 parts of silicone oil, 1.5-2 parts of a trimer catalyzer AFM 41, 1.5-2 parts of a catalyst HP-4, 3-3.6 parts of water and 35-45 parts of a flame retardant TCEP, wherein the silicone oil is silicone oil AK-8807. The preparation method comprises the following steps: adding the previously combined components into a reactor to carry out a mixed reaction, stirring to obtain a mixture at the stirring speed of 130-150 revolutions per minute for 4-5 hours; uniformly mixing acetonitrile polyester and the mixture according to a mass ratio of 1:1.5, so as to obtain the environmental-friendly flame-retardant polyurethane foaming material for the upright post. With the adoption of the material and method, the prepared environmental-friendly flame-retardant polyurethane foaming material for the upright post is flame-retardant, high-temperature-resistant, excellent in flame-retardant property, high in strength, high in rigidity and environmental-friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for columns 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. Even more stringent, the uprights must have the characteristics of high temperature resistance, high flame retardancy, high strength, light weight, and high environmental protection. The stiffness of the uprights largely determines the overall stiffness of the car body, so the uprights also need to have high stiffness. The characteristics of traditional columns 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 escap...
