Manufacturing method of steering wheel cover as well as special mold thereof and steering wheel cover

Abstract

The invention discloses a manufacturing method of a steering wheel cover, wherein the manufacturing method comprises the steps of: a. preparing raw materials; step b. putting dried raw materials into a material inlet box of an injection molding machine; step c. heating an injection molding heating system to the temperature of 180-210 DEG C, then melting the raw materials, operating the injection molding machine, and carrying out butt jointing on a mouth hole of the injection molding machine and a glue inlet hole of a molded cavity of the mold; step d. injecting the melted raw materials into the molded cavity of a steering wheel protection cover, and cooling and molding after to-be-melted materials fill up the molded cavity of the steering wheel cover; and step e. taking out a product after being molded, thus the product is manufactured, wherein the raw materials and the composition proportion of the step a are as follows: 55% of polyester polyol, 25% of water-base resin, and 20% of 1, 4-dyhydroxy hydroxy butane. The invention also discloses the steering wheel cover and a special mold thereof. The steering wheel cover provided by the invention has the advantages of good environment-friendly effect, safety, beauty and elegance, dirt prevention, easiness in cleaning, convenience in installation, comfort handfeel, high touch sense, and the like.

Description

Technical field [0001] The present invention relates to an automotive product, in particular to a non-toxic, odorless, and environmentally friendly product; it does not slip during use, is safe, and is beautiful and generous; it has the advantages of anti-fouling and easy cleaning; convenient installation, comfortable hand feeling, strong touch, etc. A manufacturing method of a steering wheel cover and a steering wheel cover thereof.

Problems solved by technology

[0008] In addition, during the whole driving process, the contact between the hands and the steering wheel is of course the most frequent, and the result is easy to generate dirt and bacteria

According to incomplete statistics from the health department, there are tens of millions of bacterial adsorption on the existing steering wheel cover

If you want to remove them, you can usually only reach these bacteria through high-temperature disinfection and ultraviolet disinfection. Generally, cleaning with a damp cloth cannot play a fundamental role

However, since the steering wheel is fixed to the vehicle, it is inconvenient to disinfect
