Special epoxy-cotton-oil-containing binding agent for automobile interior ornament surface composite leather

Abstract

The invention discloses a special epoxy-cotton-oil-containing binding agent for automobile interior ornament surface composite leather, which is prepared from the following raw materials in parts by weight: 58-62 parts of EVA (ethylene-vinyl acetate), 14-18 parts of octyl phenolic resin 203, 10-12 parts of C5 petroleum resin, 0.5-1 part of WPP polypropylene wax, 5-7 parts of oxidized polyethylene wax, 6-8 parts of modified bamboo charcoal powder, 2-3 parts of rice hull ash, 1-2 parts of nano carbon, 0.8-1.3 parts of silane coupling agent KH550, 0.1-0.2 part of antioxidant 264, 0.8-1.2 parts of antioxidant 3010, 1-2 parts of n-butyl methylacrylate, 0.5-1 part of hydroxyethyl methacrylate, 0.3-0.5 part of dibutyl maleate, 0.3-0.6 part of epoxy cotton oil and 0.1-0.2 part of triethyl citrate. The raw materials for preparing the binding agent contain the modified bamboo charcoal powder, rice hull ash and nano carbon, and thus, the binding agent has the advantages of favorable temperature tolerance and flat composite effect, can not bubble after long-term usage, and is very suitable for automobile interior ornament surface composite leather.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to an adhesive specially used for composite leather on the surface of automobile interior parts containing epoxy cottonseed oil. Background technique [0002] At present, the decorative materials on the surface of automotive 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...

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 leather are extremely high. There is an urgent need for an adhesive for automotive interior parts with excellent performance to meet production needs.
