Abstract

The invention relates to an environment-friendly water-based composite adhesive and a preparation method thereof, and belongs to the technical field of composite adhesives, and the composite adhesiveis prepared by mixing the following components in percentage by weight: 80-90% of acrylic rubber hybrid emulsion, 5-15% of acrylic colloid emulsion, 0.2-1.0% of wetting leveling agent, 0.1-0.3% of defoamer, 0.1-0.3% of preservative and the balance of water. The preparation method comprises the following steps: mixing the acrylic rubber hybrid emulsion, the acrylic colloid emulsion, the wetting leveling agent and the balance of water, stirring for 10-15 minutes at the temperature of 40-50 DEG C, adding the defoamer and the preservative, continuously stirring for 20-30 minutes, and cooling to obtain the environment-friendly water-based composite adhesive. The prepared environment-friendly water-based composite adhesive has the advantages of being high in bonding strength, good in water resistance, capable of being suitable for bonding interfaces with different properties, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of composite adhesives, in particular to an environmentally friendly water-based composite adhesive and a preparation method thereof. Background technique [0002] Composite glue is an adhesive required to combine paper, plastic film, cloth, leather and other materials of the same kind or different materials into new composite materials. Composite adhesive materials are widely used in the packaging fields of food, medicine and cosmetics, and most of the commonly used composite glues are solvent-based adhesives. Solvent-based adhesives have potential potential for areas with strict safety requirements such as food, medicine and cosmetics. Security Risk. Therefore, it is imminent to develop water-based adhesives suitable for the above-mentioned fields. [0003] At present, the existing Chinese patent with the publication number CN108865008A discloses an adhesive of an acrylate emulsion, which is prepared fro...
