Abstract

The invention belongs to the technical field of high polymer materials, in particular to a preparation method of a low VOC polyurethane automobile steering wheel. The polyurethane automobile steeringwheel is prepared and processed from materials A and B, wherein, the material A consists of polyether polyol, vegetable oil, amine catalysts, hydroxyl silicone oil, a chain extender and a foaming agent; and the material B consists of liquefied MDI and crude MDI. The method selects low volatilization and reactive raw materials, and the production method is not only simple and easy to implement, butalso has the advantages of environmental protection, no pollution and the like. The prepared steering wheel reduces the content of volatile organic compounds on the premise of not affecting other performances of the polyurethane steering wheel for automobiles, and can meet the requirements of the middle and high-end automobile market on the low VOC polyurethane steering wheels.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a method for preparing a low-VOC polyurethane automobile steering wheel. Background technique [0002] With the rapid development of the domestic automobile industry and the increasing awareness of people's health and environmental protection, mid-to-high-end vehicles have higher and higher requirements for vehicle interiors. Steering wheels made of domestic traditional polyurethane technology can no longer meet the needs of these vehicle accessories; Steering wheels are expensive. Therefore, the research and development of localized low-VOC steering wheels has been mentioned on the agenda of current domestic automobile development. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a method for preparing a low-VOC polyurethane automobile steering wheel with simple p...
