Environment-friendly high-flame-resistance polyurethane foaming material for fender and preparing method thereof

Abstract

The invention discloses an environment-friendly high-flame-resistance polyurethane foaming material for a fender and a preparing method thereof. The polyurethane foaming material is prepared from isocyanate and a combined material by mass ratio of 1:1.8; the combined material is prepared from, by mass, 55-65 parts of polyether 835, 15-18 parts of polyether 10200, 25-35 parts of polyether 10300, 35-40 parts of polyether 8310, 2.5-3.8 parts of silicone oil AK8804, 1.2-1.8 parts of a catalyst HP17, 1-1.5 parts of a catalyst HP50, 3.0-3.3 parts of water and 35-40 parts of fire retardant TCPP. By adopting the material and the method, the prepared foaming material is high in flame resistance and not prone to combustion when catching a fire and ensures fireproof safety of a vehicle and personal safety, in addition, the prepared fender is light in weight and capable of meeting the weight requirement of the vehicle, and no poisonous and harmful substance for the human body is released as the raw materials used in the foaming material are environment-friendly materials.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to an environment-friendly and highly flame-retardant polyurethane foam material for fenders and a preparation method thereof. Background technique [0002] With the development of the automobile industry, the fender is an important part of the car, and its fire safety is very important. In addition to the fire safety, the existing fender needs to have lightweight requirements to adapt to the vehicle The overall weight requirement, in order to achieve this purpose, people try various materials as the material of the fender, but the pursuit of light weight also reduces the safety, and it is often easy to cause a fire when encountering a failure or an accident Therefore, how to meet the requirements of lightweight and have flame retardant properties to ensure safety is a difficult technical problem to solve. In addition, the existing fender materials are not env...
