Problems solved by technology

Especially when bonding substrates with heavy ink and varnish systems, ordinary hot melt adhesives only bond the ink or varnish layer on the surface, and hot melt adhesives are easily plasticized or dissolved by plasticizers and organic solvents on the surface, thus greatly Affected bond strength

Abstract

The invention relates to the hot melt adhesive field, and especially discloses a cross-interface penetration adhesive which can achieve penetration adhesion to a surface film or a gold stamping layer. The penetration adhesive is composed of, by weight, 1-10 parts of ethylene-acrylic acid copolymer wax, 2-12 parts of paraffin, 10-18 parts of maleic anhydride grafting EVA, 10-21 parts of EVA with a high VA content, 6-15 parts of metallocene catalysis polyolefin, 10-18 parts of dehydrated malic acid abietin, 10-25 parts of rosin glyceride, 1-8 parts of liquid-state C5 petroleum resins, 0.5-2 parts of leveling agents, 1-6 parts of plasticizers, 0.2-1.2 parts of high-molecular coupling agents and 0.2-1 part of antioxidants. The obtained cross-interface penetration adhesive can penetrate through printing ink and the like and adheres to internal organic matters, the adhesion fastness is raised and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of hot melt adhesives, in particular to a cross-interface permeable adhesive. Background technique [0002] When the existing smooth film or bronzing paper is packaged, when the existing viscose is bonded to it, it can only be bonded to its surface, resulting in poor bonding fastness, and it is easy to make the viscose and the surface film Or the bronzing layer falls off together, affecting its normal use. [0003] When bonding ordinary coated paper, pressed powder paper, etc., the hot melt adhesive has already started to solidify on the surface, and has not penetrated into the inside of the paper, so degumming is very easy to occur. Especially when bonding substrates with heavy ink and varnish systems, ordinary hot melt adhesives only bond the ink or varnish layer on the surface, and hot melt adhesives are easily plasticized or dissolved by plasticizers and organic solvents on the surface, thus greatly affect the b...
