A method for compounding woven fabrics on the surface of an automobile door trim

Abstract

The invention provides a method for compounding a woven fabric on the surface of a car door interior trim part. The method is characterized by spraying a binder on the surface of the interior trim part needing woven fabric compounding and then compounding the woven fabric, wherein the binder is prepared from the following raw materials in parts by weight: 60-65 parts of EVA (ethylene-vinyl acetate copolymer), 8-12 parts of thermoplastic elastomer SBS, 7-12 parts of terpene resin T-110, 3-5 parts of microcrystalline wax, 0.3-0.7 part of trioctyl trimellitate, 0.2-0.4 part of epoxidized soybean oil, 0.5-1 part of silane coupling agent kh540, 0.1-0.2 part of magnesium oxide, 4-6 parts of modified nano attapulgite, 0.1-0.3 part of ferrocene, 0.5-1 part of dibutyl maleate, 0.5-0.8 part of styrene, 0.7-0.9 part of dimethyl carbonate, 0.1-0.2 part of chlorinated paraffin, 1-2 parts of nanocarbon and 0.5-1 part of tree ash. The method has the beneficial effects that the molding process is adopted for automatic trimming, so the efficiency is high; and meanwhile, the specific binder is adopted, so the woven fabric has high binding strength, is flat and can not bubble in long-term use.

Description

technical field [0001] The invention belongs to the technical field of manufacturing automobile parts, in particular to a method for compounding woven fabrics on the surface of automobile door trim parts. Background technique [0002] At present, the decorative materials on the surface of automobile doors include knitted fabrics or leather, etc., and the molding process of the products is a molding process or a low-pressure injection molding process. When molding, the fabric is often cut first, and then the edge is molded. The cutting craftsmen use the most, and each person's cutting method is different, so the consistency of the product cannot be guaranteed. The production efficiency of the molding process is low, and the defective rate is high. The amount of labor used is large, and the entire production process from semi-finished products to finished products is complicated. However, the cost of the low-pressure injection molding process is too high, the investment in eq...

Problems solved by technology

When molding, the fabric is often cut first, and then the edge is molded. The cutting craftsmen use the most, and each person's cutting method is different, so the consistency of the product cannot be guaranteed. The production efficiency of the molding process is low, and the defective rate is high. The amount of labor used is large, and the entire production process from semi-finished products to finished products is complicated

However, the cost of the low-pressure injection molding process is too high, the investment in equipment is large, and the requirements for the extension of the fabric are extremely high.
