Abstract
The invention discloses a water-borne paper-plastic laminating adhesive and a preparation method thereof. The laminating adhesive comprises 30 to 50 parts of butyl acrylate, 40 to 50 parts of vinyl acetate, 3 to 10 parts of acrylic acid, 2 to 3 parts of crosslinking monomer and 0 to 3 parts of other functional monomers. The invention hast the advantages that: the water-borne paper-plastic laminating adhesive is safe, nontoxic, non-combustible and nonexplosive, and has good weatherability and good laminating fastness; and a laminated product has high finishment and good performance.
Description
Technical field
The present invention relates to the adhesive article field, relate in particular to a kind of aqueous paper plastic composite gum and preparation method thereof.
Background technology
Paper is compound to be an important technology technology of packing.Paper can be moisture resistance, antifouling behind composite polymeric film (as BOPP, PET, PVC), increases stiffness, and color is more gorgeous simultaneously, and therefore, this technology is extensive use of in packages printing circle, and use range and usage quantity are all in rising trend.Paper compound technology has multiple, wherein uses maximum, prevailing the compound of solvent-borne type glue that toluene makes solvent that also be to use.This class glue is made solvent by toluene, and macromolecular materials such as dissolving SBS, rosin, terpenes are made, and finished product is a solid content about 45%, becomes 25% left and right sides concentration with dilution with toluene again during use.These solvents finally all are discharged in the air, cause serious toxic to pollute, and disaster hidden-trouble are serious.In addition, a large amount of uses of natural rosin also cause the ageing resistance of product poor, meeting flavescence after combination product is of long duration, and fastness descends serious.The high-melting-point of SBS also makes the fusing point height of glue, and melt viscosity is big, and composite prod has white point.These shortcomings have seriously limited the application of this class recombining process.
Summary of the invention
A technical problem to be solved by this invention is: a kind of safety non-toxic is provided, do not fire not quick-fried, the aqueous paper plastic composite gum that good, the compound fastness of weathering resistance is good, composite prod is highly polished, performance is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of aqueous paper plastic dry-type composite glue according to the weight part meter, comprises 30～50 parts of Butyl acrylates, 3～10 parts in vinyl acetate between to for plastic 40～50, vinylformic acid.3～3 parts of cross-linking monomers; 0.5～1 part of ammonium persulphate.
Described cross-linking monomer is the polyamino compound, and molecular structure is H
2N-(CH
2O) nCH
2-NH
2, n is 15～20.
Described other function monomer is the mixture of methacrylic acid and Propylene glycol monoacrylate, and blending ratio is 1: 3～5.
The preparation method of composite gum may further comprise the steps:
1) monomer mixes by formula ratio, sends into homogenizer and carries out emulsification 10～20 minutes, obtains pre-emulsion in preferential 15 minutes;
2) under 80～85 degree, add pre-emulsion 5～15% and initiator ammonium persulfate 20～40%, in reactor, carry out 10～20 minutes seed reaction;
3) drip remaining breast and change liquid and initiator in advance, dropwised in 80～120 minutes;
4) insulation is 0.8～1.5 hour;
5) be cooled to the following cooling discharging of 40 degree.
Beneficial effect of the present invention: replace toluene with water, adopt voluntarily the synthetic macromolecule emulsion to make adhesives, weathering resistance is good, and compound fastness is good, and composite prod is highly polished, and is nontoxic, do not fire not quick-fried, very favourable to environment protection.
