Polyurethane self-skinning composite (special for automobile steering wheel)
The self-skinning composite material for automobile steering wheel is a new type of polyurethane polymer material. Steering wheel, as an indispensable interior part of automobile, undertakes the important responsibilities of remote control automobile and ensuring safety. With the development of automobile industry, people not only put forward higher requirements for its performance, but also for its comfort, safety and environmental protection.
At present, most of the steering wheel cladding materials on the market are polyurethane materials with full water foaming formula. There are some problems in this formula, such as thin crust layer, small stomata on the surface of the product, high content of VC and large odor. Therefore, in order to reduce the surface porosity by increasing the density of polyurethane foam and increasing the thickness of polyurethane foam in production, this method will increase the weight of the products and do not meet the requirements of lightweight.
In order to overcome the technical defect of this all-water formula, Henry engineers have successfully developed a new method of preparing polyurethane self-crusting composite for automobile steering wheel by improving the formula on the basis of a large number of experiments. The composite material has low volatility, low atomization and is a reactive raw material. The prepared automobile steering wheel has not only low density, beautiful surface, but also physical and mechanical properties. It has the advantages of low odor, environmental protection and wide applicable temperature.
Since the crust composite material was introduced into the market, it has received unanimous praise from manufacturers, and has been well promoted and applied.
