Problems solved by technology

It has the characteristics of good aging resistance, environmental protection and odorless. In recent years, automobile manufacturers have been improving the interior environment of the car, and the control of odor and toxicity has become more and more strict; as the competition in the automobile industry intensifies, automobile manufacturers need to purchase more durable products. At the same time, in order to reduce environmental pollution and reduce the fuel cost of car owners, automobile manufacturing is also developing in the direction of lightweight; traditional composite materials have poor storage stability, and the finished product will age after several years of use, which cannot meet Usage requirements

Abstract

The invention relates to an aging-resistant and environment-friendly polyurethane foam composite material and a preparation method thereof. It includes material A and material B; material A includes: polyether polyol, polymer polyol, foam stabilizer, catalyst, auxiliary agent, crosslinking agent and foaming agent; material B includes: toluene diisocyanate, modified diisocyanate Benzyl methane diisocyanate; the auxiliary agent is an aldehyde scavenger; the foaming agent is a composite foaming agent, which is composed of a mixture of cyclopentane and n-pentane and pure water. Preparation of material A: heat polyether polyol and polymer polyol, then mix them in the reaction container, add catalyst, auxiliary agent, crosslinking agent, then add foam stabilizer and foaming agent, and react; The preparation method comprises the following steps: mixing and stirring liquefied MDI and polymerized MDI, then adding TDI 80 / 20, and charging after passing the test. The polyurethane foam produced by the combined material has low density, is environmentally friendly and non-toxic, and has good aging resistance.

Description

technical field [0001] The invention relates to an aging-resistant and environment-friendly polyurethane foam composite material and a preparation method thereof.
