High-position bumper environment-friendly flame-retardant polyurethane foaming material and preparation method thereof

Abstract

The invention discloses a high-position bumper environment-friendly flame-retardant polyurethane foaming material and a preparation method thereof. The high-position bumper environment-friendly flame-retardant polyurethane foaming material comprises the following components in percentage by mass: acetonitrile polyester and a combined material with the mass ratio being 1:1.65, wherein the combined material consist of the following components in parts by mass: 35 to 45 parts of polyester 330, 25 to 35 parts of polyester 3350, 9 to 12 parts of polyester 400, 2.5 to 3.5 parts of silicone oil, 1.2 to 1.8 parts of a catalyst HPF1, 1.0 to 1.5 parts of a catalyst S20, 3.0 to 3.8 parts of water and 33 to 39 parts of a flame retardant TCPP; the silicone oil is silicone oil AK-158; the components of the combined material are added into a reaction kettle to perform mixing reaction at the stirring speed being 130 to 150 r / min for 4 to 5 hours to obtain the combined material, the acetonitrile polyester and the combined material are mixed uniformly according to the mass ratio of 1:1.65 to prepare the high-position bumper environment-friendly flame-retardant polyurethane foaming material. By adoption of the materials and the method, the prepared high-position bumper environment-friendly flame-retardant polyurethane foaming material is flame-retardant and high-temperature resistant, has high flame retardance, high strength and long service life, and is environmentally friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for a high-position 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 auto parts have also increased significantly. As a part of safety precautions, people have stricter requirements for bumpers. High temperature resistance, high flame retardancy, high strength, light weight, long service life, 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. . Th...
