Abstract

The invention discloses aging-resistant butyronitrile emulsion adhesive for non-woven fabrics. The aging-resistant butyronitrile emulsion adhesive comprises, by weight, 24-50 parts of nitrile rubber, 8-10 parts of ethylene propylene diene monomer rubber, 16-25 parts of phenolic resin, 50-80 parts of ethyl alcohol, 8-15 parts of borax, 10-15 parts of carbon black, 8-15 parts of triphenyl phosphate, 6-12 parts of zinc oxide, 0.8-1.8 parts of oleic acid, 3-8 parts of anti-aging agents and 2-8 parts of coupling agents. The invention further provides a method for preparing the aging-resistant butyronitrile emulsion adhesive for the non-woven fabrics. The aging-resistant butyronitrile emulsion adhesive for the non-woven fabrics and the method have the advantages that the aging-resistant butyronitrile emulsion adhesive is high in adhesive strength and excellent in insulation and aging-resistant performance; the triphenyl phosphate is added into the aging-resistant butyronitrile emulsion adhesive in a formula, accordingly, the stability, the flame retardance and the antioxidant property of the aging-resistant butyronitrile emulsion adhesive can be effectively improved, and the aging-resistant butyronitrile emulsion adhesive has excellent light stability functions and is excellent in toughness; raw materials for the aging-resistant butyronitrile emulsion adhesive are safe and are free of pollution, processes are easy to implement, production procedures are environmentally friendly, the aging-resistant butyronitrile emulsion adhesive is low in preparation cost, and accordingly the aging-resistant butyronitrile emulsion adhesive and the method can be widely applied.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an aging-resistant nitrile latex adhesive for non-woven fabrics. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color Inexpensive and recyclable. For example, polypropylene (pp material) pellets are used as raw materials, and are produced by continuous one-step method of high temperature melting, spinning, laying, hot pressing and coiling. It is called cloth because of its appearance and certain properties. With the rapid development of the non-woven industry, new requirements have been put forward for adhesives, that is, the non-woven fabric must maintain a certain bond strength during the use process. For non-wove...
