Abstract
The present invention relates to a preparation method of aqueous lustering oil for paper. In the method, acrylic acid series monomers or unsaturated monomers are copolymerized in free-radical emulsion under the condition of 60 to 90 DEG C by using acrylic resin with a high acid value and a low molecular weight as dispersion resin, using a surface active agent combining negative ions with non-ions as an emulsifying agent and using persulphate as an initiating agent; afterwards, prepared wax emulsion, a small quantity of film-forming additives and other auxiliary agents are added and neutralized by ammonia water to obtain products by filtering. The aqueous lustering oil prepared by the preparation method has the characteristics of low toxicity and odor, little environment pollution, high glossiness, abrasion resistance, high water resistance, long storage time, high service stability, etc., and can be widely applied to surface decoration for packaging various paper products.
Description
Technical field
The invention belongs to technical field of polymer materials, relate to the prescription and the preparation method of water lustering oil for paper.
Background technology
At present commercially available most of water lustering oil is in order to guarantee film forming ability and glossiness, and the content of its film coalescence aid generally accounts for more than 20% of solvent part, have in addition up to 70%, this can't be called water lustering oil truly.The boiling point of film coalescence aid is generally higher, has reduced the rate of drying of film, can not satisfy the needs of high speed printing, has improved product cost simultaneously, has also brought environmental pollution.In addition, in order to improve the wear resistance that goes up optical coating, normally add cured powder or slack wax in water lustering oil, but wax powder, slack wax is dispersed relatively poor, easy curding out can have influence on the stability in storage of water-based glazing.
Summary of the invention
It is smooth, bright, wear-resisting and have the preparation method and a preparation method of styrene-acrylic resin wherein of the water lustering oil for paper of certain waterproof and dampproof function to the objective of the invention is to propose a kind of printing by paper package material surface that can make.Solve fundamentally that common water lustering oil stores, stability in use is poor, water sensitivity is strong, the not high shortcoming of glossiness, the content of organic film coalescence aid is reduced to below 2%, improve the rate of drying of oil polish, eliminate the environmental pollution and the hazard to person that exist in production and the use, reduce material cost and improve the quality of products.
The objective of the invention is to be achieved through the following technical solutions: a kind of preparation method of water lustering oil for paper may further comprise the steps:
(a) acrylic resin of a kind of lower molecular weight, high acid value under promoting, alkaline matter is dissolved in the water to be mixed with concentration be 20% solution;
(b) be dispersion resin with vinylbenzene, acrylic monomer with the acrylic resin of lower molecular weight, high acid value, the tensio-active agent two-in-one with negatively charged ion and nonionic is emulsifying agent, with the persulphate is initiator, in temperature is to carry out the free radical emulsion copolymerization under 60～90 ℃ of conditions, 4～7 hours reaction times;
(c) add emulsifying wax, a small amount of film coalescence aid and other usual auxiliaries after the copolyreaction;
(d) with ammoniacal liquor emulsion is neutralized, regulate pH value to 7～10, obtain after filtration.
Acrylic monomer is selected from vinylformic acid, methacrylic acid, acrylic or methacrylic acid C in the technique scheme
8-C
16Alkyl ester, acrylic or methacrylic acid C

4In alkyl ester, glycidyl methacrylate, acrylamide, n-methylolacrylamide, the trimethylene bisacrylamide at least three kinds; Its molecular weight of the acrylic resin of lower molecular weight, high acid value is 4000～12000, and acid number is 170-250; Promote that lower molecular weight, high acid value acrylic resin dissolved alkaline matter are quadrol; The two-in-one tensio-active agent of negatively charged ion and nonionic is a sulfo-succinic acid polyoxyethylene octyl phenol sodium salt; The initiator persulphate is selected from ammonium persulphate, Potassium Persulphate; The preferable range that ammoniacal liquor is regulated the pH value is 8～9; Film coalescence aid is selected from neopentyl glycol mono isobutyrate, ethylene glycol ethyl ether, glycol propyl ether, propylene glycol butyl ether, 1-Methoxy-2-propyl acetate etc.In the technique scheme, by weight percentage, the consumption of lower molecular weight, high acid value acrylic resin is 5～10%, and the acrylic monomer consumption is 20～60%, and the consumption of the tensio-active agent that negatively charged ion and nonionic are two-in-one is 0～0.5%, initiator persulphate consumption is 0.2～3%, the film coalescence aid consumption is 0～2%, and the consumption of water is 30～55%, and the consumption of quadrol is 0.5～1%, the emulsifying wax consumption is 2～6%, and the consumption of ammoniacal liquor is 2～4%.Above-mentioned emulsifying wax is that the polyethylene wax of 2～4 μ makes by particle diameter, and concrete steps are: under the high speed dispersor high-speed stirring, micro mist wax is dispersed in the water, makes the wax dispersion of higher concentration.Under stirring at low speed, the emulsifying agent that negatively charged ion and nonionic is two-in-one adds in the entry and mixes, and slowly adds prepared wax dispersion again, and is fully emulsified, promptly gets certain density emulsifying wax.
In the preparation of water lustering oil for paper of the present invention, introduce lower molecular weight, high acid value acrylic resin as dispersion resin, its hydrophilic carboxyl can make emulsion particle stably be scattered in the system, strengthened the stability of oil polish emulsion in storage and use, and what of this resin demand have direct influence to the gloss of last optical coating; A small amount of polyene-based unsaturated monomer of introducing in the polymerization process has improved the water resistance of last optical coating greatly as self-cross linking monomer; The emulsifying wax of introducing, one side has significantly improved the wear resistance of last optical coating, on the other hand, because the emulsifying agent of its emulsifying agent during with letex polymerization is the same, therefore emulsifying wax and benzene emulsion consistency are better, and there is not the stability problem that brings because the cohesion of wax powder is separated out in evenly blend.The consumption of emulsifying agent is little much during the common letex polymerization of the negatively charged ion of introducing and the amount ratio of the two-in-one emulsifying agent of nonionic, greatly reduces the water sensitivity of the last optical coating that emulsifying agent brings; Benzene emulsion film forming properties excellence among the present invention, the amount of required film coalescence aid greatly reduces when therefore preparing oil polish, even can, reduce environmental pollution on the one hand, reduced cost, improved rate of drying on the other hand.
The performance of listing water lustering oil for paper of the present invention (A) and commercially available water lustering oil (B) below compares:
