Abstract

The invention relates to the technical field of adhesives, in particular to an environmentally-friendly water-based adhesive. The environmentally-friendly water-based adhesive is prepared from, by weight, 60-80 parts of ethylene-vinyl acetate emulsion, 10-30 parts of tackifying emulsion, 5-10 parts of plastifying emulsion, 0.1-1 part of thickening agent, 0.1-1 part of coalescing agent, 0.1-0.5 part of surface active agent, 0.1-0.5 part of defoaming agent and 0.1-0.5 part of mildewing preventive. The invention further discloses a preparation method of the adhesive and a hat box. Compared with the prior art, the adhesive has the advantages that with the ethylene-vinyl acetate emulsion quite low in VOC content being a basic material, water-based acrylate emulsion and water-based acrylate modified rosin emulsion low in VOC content are added to prepare the environmentally-friendly adhesive with ultra-low VOC content, and the VOC content is as low as 0.8 g / L-1.5 g / L and reaches European Union VOC emission standards for imported water-based adhesives.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly water-based adhesive, a preparation method thereof, and a world cover box using the adhesive. Background technique [0002] Adhesive is a substance that firmly bonds various solid materials together by interfacial action. Adhesives are mainly composed of bonding substances, curing agents, toughening agents, diluents, fillers and modifiers, and are widely used in the automotive industry, shipbuilding industry, aerospace industry, electrical and electronic industry, construction industry, medical industry, light Textile industry and packaging industry. [0003] The wide application of adhesives has brought benefits to the industrial society, but also brought adverse effects. As we all know, there are more volatile organic compounds (VOCs) in adhesives, such as organic compounds in solvent-based adhesives. Solvents, free formaldehyde in trialdehyde ad...
