Problems solved by technology

Expensive sales price, it is very difficult to promote in our country
For this reason, China has recently introduced a water-based laminating adhesive blended with PVA emulsion and tackifying resin. Although it solves the problems of toxicity and flammability, its performance still cannot reach the level of oil-based adhesives and can only be used for some adhesives....

Abstract

This invention discloses a method for preparing a water-borne laminating adhesive. The adhesive is composed of: monomers including acrylic acid and methyl methacrylate, functional monomers including diallyl phthalate, hydroxyethyl acrylate, diallyl maleate and N-hydroxymethylacrylamide, initiator ammonium perdulfate, emulsifiers including sulfosuccinic acid and phenol ether sulfuric acid, buffers including sodium bicarbonate and ammonium bicarbonate, lauryl mercaptan, functional accessory materials including OT-75, mineral oil and water-soluble acrylic resin, pH regulator ammonia solution, and soft water. The adhesive has such advantages as no pollution, no toxicity, high safety and high cohesive force.

Description

technical field [0001] The invention relates to a laminating adhesive applied to the bonding of paper-plastic composite materials, in particular to a water-based laminating adhesive and a manufacturing method thereof. Background technique [0002] With the rapid development of the packaging industry, paper-plastic composite materials are more and more widely used in our daily life. [0003] Adhesives used in paper-plastic composites are divided into two types: oily and water-based, but the toxicity and safety problems of oil-based glue are becoming more and more prominent. The health of workers is seriously damaged, and a large amount of volatilization during the drying process can easily cause fires. It is the general trend to replace oil-based glue with water-based glue in the laminating industry. [0004] Although water-based glue is safe and environmentally friendly, its synthesis technology is difficult and the cost of raw materials used is relatively high, which is m...
