Environment-friendly anti-flaming polyurethane foaming material for intake tube assembly and preparation method

Abstract

The invention discloses an environment-friendly anti-flaming polyurethane foaming material for an intake tube assembly and a preparation method. The environment-friendly anti-flaming polyurethane foaming material for the intake tube assembly comprises ethyl cyanide polyester and combined material at mass ratio of 1:1.7, wherein the combined material comprises the following components in parts by weight: 28-38 parts of polyether 380, 25-30 parts of polyether 450, 24-30 parts of polyether 4110, 200-250 parts of reinforced glass fiber, 2.5-3 parts of silicone oil, 8-12 parts of triethanolamine, 0.9-1.3 parts of a catalyst A33, 1.6-1.9 parts of a catalyst HP-30, 3.2-3.8 parts of water and 30-40 parts of a fire retardant DMMP; the silicone oil is silicone oil AK-8807; the combined material can be prepared in the manner of adding the components into a reaction kettle for mixing reaction and stirring at 130-150r / min for 4-5h; and then the ethyl cyanide polyester and the combined material are uniformly mixed at mass ratio of 1:1.7, so that the environment-friendly anti-flaming polyurethane foaming material for the intake tube assembly can be prepared. After the materials and the method are adopted, the prepared environment-friendly anti-flaming polyurethane foaming material for the intake tube assembly has anti-flaming effect, is capable of resisting against high temperature, and has high-strength and environment-friendly properties.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant polyurethane foam material for an intake pipe 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 auto parts have also increased significantly. , lightweight, and highly environmentally friendly. The characteristics of the traditional air intake pipe assembly usually cannot achieve a more ideal effect. In the event of an emergency, the time for personnel to escape is often short due to poor flame retardancy, and there is a great potential 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...
