Few one kind.
Present invention employs brand-new UV curing technologies, using in UV ultraviolet lights, shortwave（300-800 nanometers）In UV radiation
Under, light trigger in liquid UV materials is stimulated to be changed into free radical or cation, so as to trigger the high score containing active function groups
Sub- material（Resin）Aggregate into insoluble solid paint film, this film and be typically free of volatile organic compound.Can be comprehensively purple
Outer photocuring technology main feature, damages while be avoided that again to human body, can consolidate completely under conventional ultraviolet germicidal
Change, and material property meets use requirement after solidification.
The present invention has an advantageous effect in that compared with prior art：The present invention takes curing system twice, effective solution
Single coating of having determined hydrophily and it is weather-proof, corrosion-resistant between contradiction, accomplished superperformance and it is durable in use between harmony.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Embodiment
It is a kind of can under Weak ultraviolet photograph the hydrophilic coating that be fully cured, by following constituting by weight proportion：50-
74% performed polymer, the acrylic monomer of 8-30%, the light trigger of 4-14%, the aided initiating of 1-12%, the auxiliary agent of 1-5%.
Preferably, described performed polymer is at least one in epoxy acrylate, urethane acrylate.

Principle of the invention and advantage：
（1）The UV principles of solidification are that ultraviolet light polymerization needs to produce free radical or cation to trigger polymerization, crosslinking by light trigger
Reaction is carried out by unsaturated double-bond, and under uv radiation, the light trigger in liquid UV materials is excited, and produces free radical or sun
Ion, triggers the compound with unsaturated double-bond in material（Polymer, prepolymer and monomer）Generation polymerisation, is cross-linked into net
Shape cured film.
（2）The main mode of UV hydrophilic coating film forming be chemical membrane, that is, convert film forming, after aqueous solvent is largely volatilized into
Film thing will occur a series of chemical reaction and be just changed into the polymeric membrane with certain performance its structure to be mostly netted big point
Minor structure, therefore the polymerization of chain lock addition polymerization and Step Condensation film forming two ways can be divided into.1. chain lock addition polymerization polymerization：In film forming matter
Unsaturated double-bond triggers the free chain polymerization of generation to form macromolecule membranous layer by the free radical in initiator.2. Step Condensation into
Film：Contain substantial amounts of reactive functional group group in film forming matter, such as hydroxyl, carboxyl, amino etc. itself can occur progressively to be polymerized
And form macromolecule membranous layer.
（3）This project takes brand-new UV curing technologies, and a kind of technology new solidification means for water paint is provided subtract
The hardening time of water paint is lacked, coating stability is good, without organic solvent, has eliminated conventional ultra-violet photocureable coating and carry
The problems such as polluting and stimulate caused by VOC, has the advantages that curing rate is fast, environment-friendly, good hydrophilic property.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
