Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a manufacturing process of a low volatile organic compound (VOC) polyurethane automobile instrumentboard. The polyurethane soft automobile instrument board is manufactured by taking a material A and a material B as raw materials, wherein the material A is composed of polyether polyol, vegetable oil, a tertiary amine catalyst, silicon oil, a chain extender and water, and the material B is composed of liquefied methylene diphenyl diisocyanate (MDI) and crude MDI. The low-volatile and reaction-type raw materials are selected for the polyurethane composition provided by the invention. The production method is simple, is easy to implement, and has the advantages of environmental friendliness, nopollution and the like. The content of volatile organic compounds of the prepared instrument board is reduced on the premise that other performance is not influence, and requirements of a medium-high-end automobile market on polyurethane low-VOC automobile instrument boards are met.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, relates to the technical field of preparation of polyurethane automobile dashboards, and in particular relates to a manufacturing process of low-VOC polyurethane automobile dashboards. 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, safe a...
