Description
[technical field]
The invention belongs to technical field of polymer materials, relate to the prescription and the preparation method of paper water-based glazing calendering oil.
[background technology]
At present, most of water lustering oil of selling on the market is in order to guarantee film forming ability and glossiness, and the content of its film coalescence aid accounts for more than 20% of solvent part, have in addition up to 70%, this can't be called real water lustering oil.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 cured cream in the water lustering oil again, but cured powder, cured cream is dispersed relatively poor, easy curding out can have influence on the stability in storage of water lustering oil.In view of the foregoing, the someone has proposed a kind of preparation method of water lustering oil for paper, to improve the rate of drying of oil polish, solves the shortcoming that common water lustering oil stores, stability in use is poor, water sensitivity is strong, glossiness is not high.Look into Chinese patent database, find that a kind of denomination of invention is " preparation method of water lustering oil for paper ", Granted publication number is the patent of invention of CN1175067C, and it discloses following content: " 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, and the reaction times is 4～7 hours;
(c) add cured, a small amount of film coalescence aid of emulsification and other usual auxiliaries after the copolyreaction;
(d) with ammoniacal liquor emulsion is neutralized, mediation pH value to 7～20 obtain after filtration.”。This water lustering oil, introduce lower molecular weight, high acid value acrylic resin as dispersion resin, its hydrophilic hydroxyl 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; Unsaturated and the monomer of a small amount of polyene-based of introducing in the polymerization process has improved the water resistance of last optical coating greatly as self-cross linking monomer; Its film forming properties excellence, the amount of required film coalescence aid greatly reduces during the preparation oil polish, even can.But along with more and more higher to the requirement of papery packaged product, gloss has not reached requirement with the glazing technology of coating, so, make the finish degree height of paper surface and glossiness good, all to adopt the press polish technology, just can reach desired effect.Adopt the water lustering oil for paper of above-mentioned preparation method's preparation, its technology and all more complicated of filling a prescription, and can not adopt the press polish technology to carry out glazing.Owing to by this prescription and the resulting water lustering oil of preparation method, adopt the press polish technology, oil polish even full size can be bonded on the press polish mould, and can't reach requirement.
[summary of the invention]
In view of the deficiency that exists in the background technology, the technical problem to be solved in the present invention provides a kind of prescription and technology is all fairly simple and water glazing coating that can adopt the press polish technology with and preparation method thereof.
In order to solve the problems of the technologies described above, the present invention realizes by the following technical solutions: a kind of water-based glazing press polish coating is characterized in that it is made up of the raw material of following weight ratio: 20～50 parts of acrylic monomers, 10～30 parts of alcohols polar solvents, 10～20 parts of auxiliary agents, 20～40 parts in water, 0.3～0.8 part of initiator.
Preferably, its 30 parts of described acrylic monomer, 20 parts of alcohols polar solvents, 10 parts of auxiliary agents, 40 parts in water, 0.5 part of initiator.
After making above-mentioned glazing paint glazing, can adopt the press polish technology, in above-mentioned prescription, also add 0.08～0.12 part of releasing agent.
Preferably, its 30 parts of described acrylic monomer, 20 parts of alcohols polar solvents, 10 parts of auxiliary agents, 40 parts in water, 0.5 part of initiator, 0.09 part of releasing agent.
Above-mentioned acrylic monomer is selected from a kind of in vinylformic acid, methyl acrylate, butyl acrylate, methacrylic acid, glycidyl ester, acrylic amine, Propylene glycol monoacrylate, propyl methacrylate, butyl methacrylate, the methyl esters methyl acrylate.
Described auxiliary agent is the miscellany of defoamer and flow agent.
A kind of preparation method of above-mentioned water glazing coating is characterized in that it has following steps:
A), acrylic monomer and alcohols polar solvent are mixed;
B), add initiator, under vacuum or protection of nitrogen gas, acrylic monomer is become the polymkeric substance of 5000～15000 molecular weight with alcohols polar solvent polyreaction;
C), in polymkeric substance, add neutralizing agent and auxiliary agent stirs, last thin up promptly becomes water-based glazing press polish coating.
When adapting, in step c), add releasing agent, stir with neutralizing agent, auxiliary agent with the raw material of above-mentioned adding releasing agent.
The temperature of described polyreaction is 85～105 ℃, and the reaction times is 6～8 hours.
Described neutralizing agent is organic amine, quadrol, ethylene glycol amine or ammoniacal liquor.
Adopt prescription of the present invention with and preparation method thereof resulting water glazing coating, it adopts Acrylic Acid Monomer as starting material, the hydrophilic hydroxyl of vinylformic acid can make emulsion particle stably be scattered in the system, strengthened the stability of this coating in storage and use, Acrylic Acid Monomer is as the self-cross linking monomer of polymerization process, improved the water resistance of coating greatly, after it adds releasing agent, behind the employing glazing technology, adopt the press polish technology again, coating can not be bonded on the press polish mould, higher after than glazing of resulting paper surface, glossiness, and be easy to store, the stability height, its wear resisting property and water resistance are also fine simultaneously, and its toxicity, smell is little, and time of drying is fast, pollute and lack compliance with environmental protection requirements.
The performance of listing glazing calendering oil of the present invention (A) and commercially available oil polish (B) below is relatively:
| Performance project | Oil polish (A) | Oil polish (B) |
| Film, 60 ° of gloss (dry film .20 micron) viscosity (No. 4 cup, 25 ± 1 ℃) drying time: surface drying (30-60 ℃ of second) drying time: do solid work the glazing technology that (30-50 ℃ of second) pliability/millimeter adhesive force/level pendulum dry consistency adopts | 80 20-60,20 300≤1≤2 〉=0.3 glazing, press polish | 60 10-15,30 400＞1＞2＜0.3 glazing |
As seen from the above table, every index of the present invention all is better than commercially available oil polish.
