Method for laminating woven shell fabric to surface of interior trim part of automobile roof plate

Abstract

The invention relates to a method for laminating a woven shell fabric to the surface of an interior trim part of an automobile roof plate. The method comprises the steps of: spraying a binder to the surface of the interior trim part where the woven shell fabric is required for being laminated, and then, laminating the woven shell fabric, wherein the binder is prepared from the following raw materials in parts by weight: 50-55 parts of EVA (Ethylene Vinylacetate), 5-7 parts of pentalyn, 1-2 parts of dimethyl carbonate, 15-20 parts of terpene resin, 20-25 parts of petroleum resin C5, 3-5 parts of microcrystalline wax, 1-2 parts of styrene, 1-2 parts of polyethylene glycol adipate, 0.3-0.5 part of chlorinated polyethylene, 0.2-0.3 part of N-2-(aminoethyl)-3-aminopropyl trimethoxysilane, 2-3 parts of polyisobutylene, 1-2 parts of calcium carbonate, 3-5 parts of modified nano potassium feldspar powder, 1-2 parts of wood ash, 0.5-1 part of ferrocene, 1-2 parts of antioxidant 168, 0.3-0.8 part of antioxidant 1076 and 1-2 parts of silane coupling agent kh5501. According to the method, a die pressing process is adopted, the edge cutting is automatic, and the efficiency is high; and meanwhile, the specific binder is adopted, so that the binding is high in strength and is flat, and the bubbling cannot occur during 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 an automobile roof interior trim. Background technique [0002] At present, the decorative materials on the surface of automotive roof interior parts 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, ...

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.
