Problems solved by technology

Oil-based glue has a strong smell and is not environmentally friendly, and if the solvent does not evaporate, it is easy to corrode the soft PVC foam material inside
The hot-melt glue applicator has a certain limit on the thickness of the construction material, and there is a lot of waste of glue when cleaning the machine, and when the hot-melt glue is used to glue soft PVC foam materials, the bonding strength is not high
Water-based pressure-sensitive adhesives have strong initial adhesion, but insufficient stickiness and slow drying speed
Water-based polyurethane adhesives have good initial adhesion and stickiness, but the solid content is generally low, the glue is relatively thin, and the drying speed is very slow; in addition, the price of water-based polyurethane adhesives is relatively expensive, and the product cost is high

Abstract

The invention discloses a water-based adhesive, and a preparation method and application thereof. The water-based adhesive is composed of a water-based polyurethane emulsion, a water-based acrylic emulsion, a vinyl acetate-ethylene copolymer emulsion, a butadiene-styrene latex, a water-based terpene resin emulsion, redispersible latex powder, starch, methanol, a mildewproof bactericide and water. The preparation method comprises the following steps: 1) heating the mixture of starch and water to gelatinize, thereby obtaining a starch emulsion; 2) adding a water-based polyurethane solution and methanol A into the charging basket to obtain a mixed solution; 3) adding the starch emulsion into the mixed solution to obtain a semifinished solution; and 4) sequentially adding the other components into the semifinished solution in the step 3) to obtain the water-based adhesive. The water-based adhesive is used for bonding soft PVC (polyvinyl chloride) foamed materials. The adhesive has the advantages of high bonding strength, high drying rate, environment friendliness and no toxicity, and is especially suitable for bonding soft PVC foamed materials.

Description

technical field [0001] The invention relates to a water-based adhesive, a preparation method and application thereof, and belongs to the technical field of adhesives. Background technique [0002] At present, the adhesives used for bonding soft PVC foam materials are mainly oil-based adhesives, hot-melt adhesives, water-based pressure-sensitive adhesives or water-based polyurethane adhesives, but these four adhesives have defects during use. Oil-based glue has a strong smell and is not environmentally friendly, and if the solvent does not evaporate, it is easy to corrode the soft PVC foam material inside. The hot-melt glue applicator has a certain limit on the thickness of the construction material, and there is a lot of waste of glue when cleaning the machine, and when the hot-melt glue is used to glue soft PVC foam materials, the bonding strength is not high. Water-based pressure-sensitive adhesives have strong initial adhesion, but insufficient stickiness and slow drying...
