Environment-friendly and flame-retardant polyurethane foaming material for cab deflector shields, and preparation method of environment-friendly and flame-retardant polyurethane foaming material

Abstract

The invention discloses an environment-friendly and flame-retardant polyurethane foaming material for cab deflector shields, and a preparation method of the environment-friendly and flame-retardant polyurethane foaming material. The environment-friendly and flame-retardant polyurethane foaming material for the cab deflector shields is prepared from the following components: ethyl cyanide polyester and a composite material, wherein the mass ratio of the ethyl cyanide polyester to the composite material is equal to 1 to 1.65; the composite material is prepared from the following components in parts by mass: 20-35 parts of polyester 10100, 15-18 parts of polyester 403, 45-55 parts of reinforced glass fibers, 3.5-4 parts of silicone oil, 8-12 parts of triethanolamine, 1.2-1.7 parts of a catalyst HP-54, 1.6-1.9 parts of a catalyst HP-80, 3.0-3.8 parts of water and 35-40 parts of a flame retardant TCEP, wherein the silicone oil is silicone oil AK-8860. The preparation method comprises the following steps of adding the components of the composite material into a reaction kettle for carrying out mixing reaction, and stirring for 4-5h at the speed of 130-150r/min to obtain the composite material; then, evenly mixing the ethyl cyanide polyester with the composite material according to the mass ratio of 1 to 1.65 so as to obtain the environment-friendly and flame-retardant polyurethane foaming material for the cab deflector shields. After the materials and the method are adopted, the prepared environment-friendly and flame-retardant polyurethane foaming material for the cab deflector shields is flame-retardant, high-temperature-resistant, high in strength and environmentally friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for a cab deflector 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. The characteristics of strength, light weight, and high environmental protection, the characteristics of the traditional cab deflector usually cannot achieve a more ideal effect. In the event of an accident, the time for personnel to escape is often short due to poor flame retardancy, and there is a big problem. Security risks. 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.
