Abstract

The invention belongs to the technical field of polymer materials, and specifically relates to a manufacturing process of a high-adhesion polyurethane automobile instrument panel. The polyurethane automobile instrument panel is manufactured from a material A and a material B, wherein the material A is prepared from polyether polyol, polyester polyol, a catalyst, silicone oil, a chain extender andwater, and the material B is prepared from liquefied MDI and crude MDI. The low-volatility reactive composition materials are selected, the production method is not only environmentally friendly and easy to implement, but also has high bonding performance, and the requirements of middle-and-high end automobile markets for high-cohesion polyurethane automobile instrument panels are met.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and relates to the preparation technology of a polyurethane automobile instrument panel, in particular to a production process of a highly cohesive polyurethane automobile instrument panel. Background technique [0002] With the improvement of people's living standards and the rapid development of the domestic automobile industry, the demand for mid-to-high-end vehicles has increased sharply. The dashboards made of traditional polyurethane technology in China can no longer meet the decoration needs of these vehicles; and the vehicle dashboards imported from abroad are expensive. , follow-up maintenance costs are also high. Therefore, the research and development of localized mid-to-high-end passenger car instrument panel has been put on the agenda of current domestic automobile development. Contents of the invention [0003] The purpose of the present invention is to provide a simple pr...
