Method for making fabric of automobile-trunk cover plate

Abstract

The invention discloses a method for making fabric of an automobile-trunk cover plate. The method includes the steps that 1, a glass fiber layer, a honeycomb paper core and a glass fiber layer are sequentially laminated to form a laminated structure; 2, polyurethane materials are sprayed to the front face and the back face of the laminated structure respectively; 3, the fabric is spread to a lower mold plate of a mold, then an embedded nut is put on the fabric, the laminated structure coated with the polyurethane materials is put on the fabric, and after mold assembling is carried out, molded materials are obtained. According to the method, as glue is not used for bonding fabric, the cost of glue and the manufacturing cost of devices required by the spraying technology, the pressing technology and the like are saved, and meanwhile the problems of overproof VOC discharging and overproof smells of the glue are greatly solved.

Description

technical field [0001] The present application relates to a car trunk, in particular to a method for making a car trunk cover fabric. Background technique [0002] In the traditional technology, the manufacturing process of the fabric of the trunk cover of the automobile mainly includes the following steps: [0003] The first step: forming the substrate, that is, the glass fiber layer + honeycomb paper core after spraying PU, and foaming in the mold; [0004] Step 2: Grinding the substrate to improve the surface roughness and improve the adhesion of the glue; [0005] Step 3: Knock in the embedded nut on the substrate; [0006] Step 4: apply glue on the fabric; [0007] Step 5: Stack the polished substrate and the glued fabric in the pressing tooling for compounding; [0008] Step 6: Cut the edge of the panel beyond the edge of the substrate. [0009] There are following defects in above-mentioned traditional means: [0010] 1) Grinding the substrate requires manpower ...

AI Technical Summary

Problems solved by technology

[0010] 1) Grinding the substrate requires manpower using equipment, and the cost is high

And uneven grinding will also cause uneven bonding effect in the later stage

[0011] 2) Using glue for bonding, because the glue contains a large amount of volatile benzene and ketones, causing VOC emission and odor exceeding the standard

[0012] 3) The substrate and the fabric are trimmed twice separately, and the edges cannot be completely aligned, which affects the appearance

[0013] 4) After cutting the fabric, you can see the section and excess glue overflowing, which affects the appearance

[0014] 5) The knock-in embedded nut is not firmly combined with the base plate, and there is a risk of falling out due to later vibration
