Environment-friendly flame-retardant polyurethane foaming material for wind guide cover and preparation method

Abstract

The invention discloses an environment-friendly flame-retardant polyurethane foaming material for a wind guide cover and a preparation method. The environment-friendly flame-retardant polyurethane foaming material for the wind guide cover is prepared from the components of acetonitrile polyester and a composite material in a proportion by mass of 1:1.4; the composite material is prepared from the following ingredients in parts by mass: 35-40 parts of polyester 3628, 200-350 parts of fiberglass, 30-35 parts of polyester 3360, 25-30 parts of polyester 1300, 3-3.5 parts of silicone oil, 1-1.5 parts of a catalyst M62, 1.5-2 parts of a catalyst M9, 3.5-4 parts of water and 38-40 parts of a fire retardant DMMP (dimethyl methyl phosphonate), wherein silicone oil AK-158 serves as the silicone oil; the preparation method comprises the steps of adding the ingredients of the composite material into a reaction kettle to perform mixed reaction, stirring at the speed of 130-150r / min, and stirring for 4-5h to obtain the composite material; then mixing the acetonitrile polyester with the composite material uniformly in the proportion by mass of 1:1.4 to prepare the environment-friendly flame-retardant polyurethane foaming material for the wind guide cover. After the materials and the method are adopted, the prepared environment-friendly flame-retardant polyurethane foaming material for the wind guide cover is flame-retardant, high temperature-resistant, high in both flame retardant property and strength, and environmentally friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for an air guide cover 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. Lightweight and highly environmentally friendly, the characteristics of traditional windshields usually cannot achieve ideal results. In the event of an emergency, 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 explore high-strength, high flame-retardant, and high-environmental protection polyurethane foam materials. Contents of the invention [0003] The object of the present invention is to overcome t...
