Description
The present invention relates to vacuum aluminum-coated industry, particularly vacuum aluminum-coated preceding body paper is handled glue.
Because the body paper before vacuum aluminum-coated must carry out pre-treatment.Glue among the Chinese patent CN86106862 to the body paper surface treatment, has good performance.But, because Gum Rosin wherein becomes fragile, and makes aluminium plating film come off after the alcohol solvent volatilization, loss of gloss when hot weather construction, has the bonding obscission, and aluminium powder comes off and has a strong impact on quality product, because its solid content is lower, glue consumption is big, and the cost of the glue and the paper of aluminizing is higher.
The purpose of this invention is to provide a kind of new paper for vacuum aluminium plating pre-treating adhesive that is used for before vacuum aluminum-coated.
For realizing purpose of the present invention, the present invention adopts following technical characterictic, includes petroleum resin at least, the colloid mixture of rubber (rubber) and organic solvent.
Petroleum resin can use the petroleum resin of petroleum cracking C 9 distillate, rubber can use any natural rubber or synthetic rubber, or the epoxy glue of the two (rubber of the present invention should be that the untreated rubber that not doping and uncured are handled is rubber).Organic solvent can use fat hydrocarbon solvent, aromatic hydrocarbon solvent, esters solvent can use above-mentioned a kind of solvent separately, also can two or three kind mix and use.
Fat hydrocarbon solvent is best to use industrial naptha, and regular gasoline also can use, but because it contains detonation suppressor, causes crossed contamination.Aromatic hydrocarbon solvent is best with benzene,toluene,xylene, or several benzene mixes use.Esters solvent is best with ethyl acetate.
In addition, can successful implementation for making the present invention, the each component consumption is the petroleum resin 20～65 of (weight %) petroleum cracking C 9 distillate, natural and/or synthetic rubber 0.1～5, industrial naptha 30～60.
Body paper pre-treating adhesive of the present invention has the characteristic of other materials of containing of broad.In this glue, can also contain (weight %) and be no more than 45% rosin and/or rosin derivative, be no more than 5% polyvinyl acetal, be no more than 20% alcohol, be no more than 25% aromatic solvent, be no more than 15% ester solvent, be no more than 6% carboxamide.
Polyvinyl acetal preferably uses polyvinyl butyral acetal.Carboxamide uses urea.That is to say, also can in glue, add rosin and/or its derivative, polyvinyl acetal, alcohol, carboxamide, aromatic hydrocarbons and esters solvent.Also can be fully miscible, the normal use.
The preparation method of pre-treating adhesive of the present invention is under the condition of heating, temperature preferably is controlled between 50～120 ℃, be dosed in the reactor of whipping appts by the order that drops into solute behind elder generation's throwing solvent, insulated and stirred through 3～6 hours, make its thorough mixing, dissolving, after filtration, decolouring and deodorizing, natural sedimentation and making.Its solid content is (control charging capacity) between 40～70%, and viscosity is between 50～500cps, and outward appearance is brown or light red or red-brown translucent (or transparent) colloid.
The more used glue of the solids content of glue of the present invention is high by 10～30%, the avidity of aluminium coated and glue increases by 8～25%, and the rate of drying during gluing is brought up to 30～50m/mln by 30 original～40m/mln, and the output that gluing is low can improve 15～30%, economize on electricity 20～30%, cost descends 10～20%.The Water Vapour Permeability of the paper of handling through gluing is maximum 30g/m
2Therefore 24h, can be used as the pre-treating adhesive of the weather-proof dressing paper of food and other industries packing.
