Background technology
Along with the development of high science and technology, people are more and more higher to performance requriementss such as the decoration of coating, protection against corrosion, heatproof, cold-resistant, stain resistants, and world coatings industry is by the direction develop rapidly of solvent-borne type to high-performance, pollution-free, environment-friendly aqueous coating.UV-curing technology, with its energy-conserving and environment-protective, the feature such as easy to use, quick, obtained the development of advancing by leaps and bounds at nearly 20 years.
The coating material solidified advantage combining water-based and UV-curing technology of aqueous, environmental protective UV; solve the shortcoming of the intrinsic soft of water-borne coatings, low sticking power; achieve the application of aqueous, environmental protective, cost degradation and high-level efficiency, along with the whole world becomes the inexorable trend replacing traditional solvent-borne UV coating to the strict demand of environmental protection.
Although aqueous UV curing coating achieves considerable progress in production technology and Application Areas, but still make little progress in the pollution of solution organic solvent environment, stability and paint film mechanical property problem, the gordian technique of water-soluble UV cured resin and special addition agent does not still effectively solve.In this respect, application number be 200710031844.2 Chinese patent literature propose to get epoxy-acrylate and polyurethane-acrylate is mixed in proportion, add aqueous promoter and water mixed alkoxide solution again, add curing speed, improve fragility and the snappiness of paint film, but shortcoming is that the stability of coating is not enough, containing alcoholic solvent in solution.Application number be 200710027188.9 Chinese patent literature propose to be mixed in proportion with high molecular polymer, light trigger and water to prepare ultraviolet-curing paint, system improves film and snappiness, system organic solvent-free, but the stability of coating and emulsifying effectiveness existing problems.Application number be 200810039199.3 Chinese patent literature propose be incorporated in base polyurethane prepolymer for use as with multi-thiol and rare end group that is respectively by the method for chemical bonding, pass through from the standby aqueous polyurethane dispersion paints containing multi-thiol and polynary alkene of newborn legal system again, this method efficiently solves stability in storage and the paint film mechanical property problem of coating, but shortcoming is the use that still there is organic solvent in process of production.
Therefore, along with the raising of environmental protection standard relevant in world wide, the enforcement of enforceable environmental law Laws & Regulations, the development and production feature of environmental protection is good, the aqueous UV curing coating of good stability, quick solidifying is the road of the certainty of UV photo-cured coating industry development to replace solvent-borne type UV coating on existing market.
Summary of the invention
In order to solve, the organic solvent environment that exists in existing water-based ultraviolet (UV) curable coating pollutes in the present invention, stability and paint film mechanical property problem aspect, the invention provides a kind of environment-friendly water-based UV photo-cured coating and production technique.
The technical scheme that the present invention takes is:
A kind of environment-friendly water-based UV photo-cured coating, comprises the component of following parts by weight:
Further technical scheme is: self-control polyurethane acrylate prepolymer is by the prepolymer resin that the basis of existing patent " a kind of preparation method (200810045778.9) of aqueous photo-curing polyurethane resin " is prepared by hydrophilic modifying.
Concrete preparation method is: the isocyanic ester adding 20 to 40 weight parts in the reaction flask of logical nitrogen protection, 50 DEG C to 70 DEG C preheating 10min; 30 to 60 weight parts are added drop-wise in reaction flask with the dibasic alcohol (as polycaprolactone diols, polycarbonate ester dibasic alcohol or polytetrahydrofuran diol) of ehter bond, carboxyl, sulfonic acid or tertiary ammonium salt with the speed of 2 to 5 per second, the initiator of 0.5 to 1 weight part 2-hydroxyl-4'-(2-hydroxy ethoxy)-2-methyl phenyl ketone is added again in reaction flask, drip the butyl tin class catalyzer of 0.5 to 2 weight part, keep the stirring velocity of 350r/min, constant temperature 1h to 1.5h; Be cooled to 50 DEG C to 60 DEG C, what add 1 to 10 weight part has a hydroxyl and the alkene class end-capping reagent of one or more double bond and the amine salt forming agent of 1 to 5 weight part, constant temperature 1.5h to 2h.Cool to 30 DEG C to 40 DEG C dischargings after completion of the reaction, and obtain transparent self-control polyurethane acrylate prepolymer.
Further technical scheme is: self-control emulsifying agent has following structural formula:
Wherein n is the natural number of 8-18.
The number-average molecular weight of described self-control emulsifying agent is 600 to 1000, and its second-order transition temperature is at-25 DEG C to 80 DEG C.
Wherein, this self-control emulsifying agent can be prepared by the following method, comprising:
(1) various component is prepared according to following part by weight:
