Abstract

The invention discloses an environment-friendly foaming material for an air inlet pipe assembly and a preparation method. The environment-friendly foaming material for the air inlet pipe assembly is prepared from the following components in a mass proportion: the proportion of ethyl cyanide polyester to a combined material is 1 to 1.55; the combined material is prepared from the following components in parts by mass: 33 to 40 parts of polyether 330, 35 to 45 parts of polyether 450, 15 to 25 parts of polyether 403, 150 to 200 parts of glass fibers, 1.5 to 2.5 parts of silicon oil, 8 to 12 parts of triethanolamine, 1.2 to 1.5 parts of catalysts A33, 1.5 to 1.8 parts of catalysts HP-30, 30 to 40 parts of water, and 35 to 40 parts of flame retardant agent DMMP (dimethyl methylphosphonate). According to the environment-friendly foaming material disclosed by the invention, by adopting reasonable proportioning, the prepared foaming material is good in flame retardance and stability. According to the foaming material prepared by adopting the reasonably-proportioned environment-friendly raw materials, harmful substances cannot be released, and the damage to an environment and a human body is avoided.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant foaming 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. Quantitative, highly environmentally friendly features. Traditional air intake pipes usually cannot achieve ideal results. In the event of an accident, the poor flame retardancy will result in a 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, high-environmental protection flame-retardant foaming materials. Contents of the invention [0003] The purpose of the present invention is to overcome the defects ...
