Abstract
The invention discloses a manufacturing process of a car trunk carpet. The manufacturing process comprises the steps of: laying glass fiber cloth at the upper surface and the lower surface of a corrugated paper core, spraying polyurethane, pressing and shaping, cooling, spraying polyurethane glue and pasting a non-woven fabric to obtain a car trunk carpet finished-product. The car trunk carpet produced by the manufacturing process is easy in shaping process and environmental-protection. With the adoption of the manufacturing process of the car trunk carpet, the problems of the heavy smell, the large volatile content of a volatile organic compound, the poor rigidity, and the like of the existing car spare wheel covering plate are also solved, so that the use requirements of customers are well satisfied, and the manufacturing process is suitable for the requirements of the light weight and the environmental protection of the modern cars. Double-face spraying is adopted in the spraying process; the shaping is finished in a line production; and the process is stable.
