Abstract

The invention discloses water-based composite adhesive, which contains acrylate emulsion and a cross-linking agent, wherein the weight of the cross-linking agent is 0.1-6 percent of the weight of the acrylate emulsion; the cross-linking agent is any one or a mixture of hexamethylenediamine and adipic acid dihydrazide; and the acrylate emulsion is formed by copolymerizing a terpenes hard monomer, a terpenes soft monomer, a terpenes carboxylic acid monomer, a terpenes functional monomer, a dual-vinyl monomer and a terpenes cross-linking monomer through nuclear shells under an emulsion system. The adhesive is particularly suitable for dry-type composite adhesion between flexible package composite base materials such as a plastic film and a vacuum aluminized film which are processed through corona; has good leveling, fast drying, high transparency, capability of curing at room temperature, high initial strength, excellent peel strength, difficulty in mesh clogging and skinning, wide adaptability and low cost; and can be applied to various machine types, does not contain any organic solvent, can replace solvent adhesive at present completely, and belongs to environment friendly adhesive.

Description

technical field [0001] The invention belongs to the field of organic polymer compounds, and relates to a polymer compound obtained by reacting carbon-carbon unsaturated bonds, in particular to polyacrylate. Background technique [0002] Dry lamination of flexible packaging is the use of adhesives to corona-treated stretched polypropylene (BOPP), polyvinyl chloride (PVC), polystyrene (PS), nylon (PA), polyethylene (PE), cast polypropylene (CPP), polyester (PET), low-density polyethylene (LDPE), coated paper, pearlescent film and CPP or PET aluminized film, aluminum foil and other substrates are combined together, which greatly improves the application performance of packaging materials. Widely used in food packaging, pharmaceutical packaging, cosmetics and detergent packaging, etc. [0003] Adhesives used in dry lamination of flexible packaging are divided into three types: solvent-based, solvent-free and water-based. Solvent-based adhesives use toluene or ethyl acetate as ...
