Problems solved by technology

In the 1990s, the use of solvent-based box glue was more common, but with people's emphasis on environmental protection and strict restrictions on exports, the use of solvent-based box glue was restricted. Now most of the glue used in the market is water-emulsion paste. Box glue
[0003] The existing water-emulsion type box glue made by using acrylate as a polymerized monomer always has some disadvantages during use: (1) the adhesion is not strong enough, especially for paper to PET (polyethylene terephthalic acid). Ethylene glycol ester), OPP (polypropylene) and other difficult-to-bond substrates have poor adhesion; (2) High temperature aging resistance

Abstract

The invention discloses environment-friendly water-based high-viscosity box pasting glue and a preparation method thereof. The environment-friendly water-based high-viscosity box pasting glue comprises the following components: an ethylene-1-octylene copolymer emulsion, a thickening agent, a curing agent, filler, a defoaming agent, an environment-friendly plasticizer, tackifying resin and water-based polyurethane-epoxy resin-acrylate composite resin. The preparation method comprises the following steps: feeding the components into a dispersion kettle, and stirring and dispersing all the components to obtain the environment-friendly water-based high-viscosity box pasting glue. The ethylene-1-octylene copolymer emulsion in the box pasting glue is high in bonding strength and outstanding in tensile strength and tearing strength; the molecular structure of the waterborne polyurethane-epoxy resin-acrylate composite resin is net-shaped, and the waterborne polyurethane-epoxy resin-acrylate composite resin is matched with other components, so that the box pasting adhesive has relatively high bonding strength, excellent water resistance and solvent resistance and storage stability. Experimental results show that the product has good initial viscosity, bonding strength, heat resistance and mechanical stability.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly water-based high-viscosity box glue and a preparation method thereof. Background technique [0002] As the market's requirements for product packaging are getting higher and higher, all kinds of beautifully printed packaging products have put forward higher requirements for the adhesives used, which has also promoted the rapid development of packaging adhesives. Especially for many companies that produce high-quality color boxes, it is necessary to glue special paper, cardboard, laminated color paper, etc. with industrial cardboard, MDF, etc. by hand through a gluing machine to make various high-end wine boxes and gift boxes. etc., the industry is accustomed to call this type of glue box glue, color box glue, fine mounting glue, mounting box glue, sticky box glue, water-based yellow glue, etc. At present, there are two main types of box glues on the mar...
