Abstract

The invention discloses a production method of pad cotton of a cover plate of an automobile spare tire. The production method comprises following steps of material weighing; pre-opening; precise opening; even and orderly weighing; material spreading and net forming; drying at a set temperature; cold rolling and shaping; and cutting. In this way, problems of excessive formaldehyde, horizontal and longitudinal tearing and poor stretching performance of pad cotton of a spare tire are solved; dust producing rate of a hair felt is reduced; small of the product is improved; and production environment is improved.

Description

technical field [0001] The invention discloses a production method of an automobile spare tire cover pad and belongs to the technical field of automobile interior trim production. Background technique [0002] Spare tire cover pad is a material installed under the car spare tire cover, which plays the role of heat insulation, sound insulation, sound absorption and shock absorption. In the era of more and more pursuit of high performance, environmental protection, energy saving, light weight and personalization, the interior of the car, like the appearance of the car, has become an important factor for people to buy a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as odor, formaldehyde content, dust content, and appearance of the spare tire cover pad have become bottlenecks, restricting the development of the spare tire cover pad. The existing spare tire cover pads mainly have the f...
