Abstract

The invention relates to a production method of an automobile trunk carpet, comprising the following steps: (1) spraying glue and laminating: placing a terylene blanket in a positioning and laminating tooling, positioning the blanket, evenly spraying glue on one side of the positioned terylene blanket, and laminating the terylene blanket with one side of a polypropylene hollow board to obtain a semi-finished product, wherein the glue spraying amount is 90-110g/m<2>; (2) evenly spraying glue on the other side of the polypropylene hollow board of the semi-finished product, and the sticking a non-woven cloth on the other side of the polypropylene hollow board after glue spraying, wherein the glue spraying amount is 90-110g/m<2>; (3) molding and punching: placing the semi-finished product after the non-woven cloth is stuck on in a die for molding and punching, wherein the molding pressure is 7-9mpa and the molding time is 55-65s; (4) covering: covering the rims of the semi-finished product after molding and punching by covering clothes; and (5) installing and inspecting accessories: adhering cotton pads and installing stay cords on the covered semi-finished product to obtain a finished product. The method in the invention has saved production cost, is environment-friendly and has no pollution.

Description

technical field [0001] The invention relates to a method for producing a car trunk carpet, which belongs to the technical field of car interior parts, especially a method. Background technique [0002] Automotive interior parts are generally installed inside the car body to play the role of beautification, protection, and sound insulation and sound absorption. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the exterior decoration of automobiles, like the performance of automobiles, has attracted more and more attention from people. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as low weight, high strength, high load capacity, and sound absorption of the luggage carpet have become bottlenecks, restricting the development of the luggage carpet. The disadvantages of the existing trunk carpet are: heavy ...
