Abstract

The invention provides a novel environment-friendly aqueous joint adhesive which is mainly prepared by the reaction of butyl acrylate, methacrylic acid, a VAE (Vinyl Acetateethylene Emulsion), a PVAC (Polymer Vinyl Acetate) emulsion, lauryl sodium sulfate, rosin adhered resin, p-methylbenzene sulfonic acid, sodium polyacrylate protective colloid, ammonium persulfate, BL-100 organosilicone foam inhibitor, OP-10 dispersant and a magnesium chloride coupler. The invention further provides a preparation method of the aqueous joint adhesive. The aqueous joint adhesive is nontoxic, safe and environment-friendly and simple to operate, and can directly replace natural rubber joint adhesive without changing the device. Compared with natural rubber self-adhesive glue, the physical properties of the aqueous joint adhesive are substantially not changed, and the aqueous joint adhesive better carries forward the advantages of the original natural rubber self-adhesive glue. Compared with natural rubber self-adhesive glue, the cost of the aqueous joint adhesive is lowered to a greater extent, and the raw material source is easier and more convenient to get.

Description

technical field [0001] The invention relates to a novel water-based environmentally friendly acrylic adhesive and a preparation method thereof, in particular to a water-based adhesive and a preparation method thereof. Background technique [0002] Laminating glue is mainly coated on the surface of woven fabrics, non-woven fabrics, sponges, EVA sheets, genuine leather or PU leather. The surface shows less cohesive force, but under the extrusion of external force, the cohesive strength will increase. It can be widely used in the processing of some shoes, clothing and packaging materials. [0003] Adhesive glue currently on the market mainly uses natural rubber as the main raw material for production. Not only the raw material cost is high, but also natural rubber contains many harmful chemical substances that are difficult to separate, and a large amount of ammonia water must be added in production. With the continuous improvement of human health and environmental requiremen...
