Description
Technical field
The present invention relates to technical field prepared by environmental protection coating material, be specially a kind of ultraviolet-curing paint.
Background technology
Ultraviolet-curing paint (UVcuringcoating, be called for short (UVCC), be a kind of environment-friendly and energy-efficient coating of the exploitation sixties in 20th century, since 20 century 70s realize commercialization abroad, remain the average annual growth of 8%-10% always.It is advantageous that curing speed is fast, almost instantaneous film forming, less use volatile solvent, energy-efficient, solidification process can automated operation, is applicable to continuous mass production.UVCC meets the requirement of pay attention to day by day environmental protection within the scope of our times, is described as environmental friendly product of new generation and rectifies.Its curing light source is generally UV-light (UV), electron beam (EB) and visible ray; because electron beam curing apparatus is comparatively complicated; cost is high and the material of visible-light curing is difficult to preservation; therefore the most frequently used at present curing light source is still UV-light; ultraviolet-curing paint is widely used in and closely bound up field of living by people; as being used in the shell of the article such as mobile phone, computer, digital camera, toy for children; to play the effect beautifying object and protection object; and, disclosed by correlation technique also has in the patent literature.
As Chinese invention patent application CN104341979A, open a kind of clean taste color inhibition type ultraviolet-curing paint and preparation method thereof.Described clean taste color inhibition type ultraviolet-curing paint, comprise the component of following weight part: resin 30-45 part, reactive thinner 35-55 part, matting agent 6-10 part, wax powder 0.8-1 part, anti-settling agent 0.3-0.5 part, defoamer 0.1-0.3 part, flow agent 0.2-0.5 part, dispersion agent 0.1-0.5 part, light trigger 3-5 part, BP0.5-1 part, reactive amines 0.5-1.5 part, stopper 0.01-0.05 part, wherein, described resin is modified epoxy acrylic ester resin, aliphatic urethane acrylate resin and hyperbranched polyester acrylic ester resin.Clean taste color inhibition type ultraviolet-curing paint of the present invention, has the anti-yellowing property that smell is low and good concurrently, can meet furniture industry to the higher requirement of UV photo-cured coating on low smell and color inhibition.
As Chinese invention patent application CN103205183A discloses a kind of tasteless nontoxic UV-curable waterborne coatings and preparation method thereof, one or both in a kind of and polyester acrylate resin in water miscible unsaturated polyester resin, unsaturated carbamide resin of polyester amide, Epocryl, polyurethane acrylate resin are mixed, with 1173,184, one or more in TPO are for light trigger, and adding auxiliary agent, water or aqueous ethanolic solution, allotment obtains UV-curable waterborne coatings.Such ultraviolet-curing paint has water-based, curing speed is fast, glossiness is high feature.Such ultraviolet-curing paint is expected to be used as gloss oil for paper, also can be used for the coating protection of plastics, glass, woodenware, metal etc.
But it is not very desirable that existing ultraviolet-curing paint still shows in thermotolerance, erosion resistance.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of ultraviolet-curing paint is provided, be applicable to make printed-wiring board (PWB) and ground not easily adhere to or flexible substrate, described ultraviolet-curing paint coating laser curing velocity is fast, coating hardness is high, good corrosion resistance, thermotolerance are better, material wettability is good, little to skin irritation, further, raw material be easy to get, low price.
The present invention can be achieved through the following technical solutions:
The invention discloses a kind of ultraviolet-curing paint, described ultraviolet-curing paint is made up of by weight following composition: bisphenol A epoxy acrylate 16 ~ 25 parts, Epoxy Phenolic Acrylates 4 ~ 10 parts, epoxidized oil propionic ester 8 ~ 15 parts, reactive thinner 10 ~ 25 parts, light trigger 1 ~ 5 part, organic amine 6 ~ 12 parts, auxiliary agent 1 ~ 4 part, solvent 30 ~ 50 parts;
Described bisphenol A epoxy acrylate can replace with ricinolic acid modified epoxy, replaces bisphenol A epoxy acrylate can improve the performance of coating in thickness, snappiness, sticking power, shock-resistance etc. with ricinolic acid modified epoxy;
Described reactive thinner is one or more in tripropylene glycol acrylate, trimethylolpropane acrylates, neopentylglycol diacrylate, Viscoat 295, ethoxyquin trimethylolpropane tris propylene vinegar, in photocuring system, reactive thinner not only plays the effect of regulation system viscosity, and usually can participate in film-forming, less volatile is in air, imparting system environmental protection characteristic, wherein, ethoxyquin Viscoat 295 also correctability to the pungency of skin; The flexibility that tripropylene glycol diacrylate has had, can reduce composition viscosity, well adheres to promoter action in addition;
Described light trigger is one or more in benzoin dimethylether, benzophenone, 1-hydroxy-cyciohexyl-benzophenone, 2,4,6-trimethylbenzoyl diphenyl phosphate oxidations; Because the absorption peak of 1-hydroxyl-ring Ethyl-phenyl ketone is at 325-330nm, wave band is shorter, good light-initiated effect is played in coating, and 2,4,6 diphenyl phosphate oxidation absorption peaks are at 350-400nm, wave band is comparatively large, has good deep cure effect, has the effect of bleaching simultaneously, both are combined and make the present invention be provided with good light-initiated effect and deep cure effect simultaneously, make solidification more complete;
Described organic amine is one or more in diethanolamine, trolamine, triethylamine, N, N-dimethyl benzylamine;
Described auxiliary agent is flow agent, wetting agent, defoamer, in order to reach good flowing planarization in coating system, needs to add people's flow agent; In order to the formation of bubble in inhibition system, need to add defoamer; In order to the wetting effect strengthening system needs to add wetting agent; When making used additives, should to select as far as possible can participate in curing reaction, most of ordinary adjuvants is stayed because not participating in photocuring reaction by strap clamp pin hole in cured film, returns glutinous grade for film defect;
Described flow agent is poly-methyl alkyl siloxane solution; Described wetting agent is Bi Ke BYK-103 or vapour bar EFKA-4010; Described defoamer is acrylic-functional polydimethylsiloxane;
Described solvent is ketone and alcohol ether organic solvent, described ketone comprise acetone, butanone, methyl-n-amyl ketone, methyl-isoamyl ketone one or more, described alcohol ethers comprise ethylene glycol monomethyl ether, ethylene glycol ethyl ether one or both.
A kind of ultraviolet-curing paint of the present invention, has following beneficial effect:
The first, the photosensitive resin of ultraviolet-curing paint of the present invention choose bisphenol A epoxy acrylate, Epoxy Phenolic Acrylates, epoxidized oil propionic ester combination to improve coating laser curing velocity fast, and coating hardness is high, good corrosion resistance, thermotolerance better, and coating wettability is good.
The second, bisphenol A epoxy acrylate is replaced can to improve the performance of coating in thickness, snappiness, sticking power, shock-resistance etc. with ricinolic acid modified epoxy in this preferred version.
Three, the reactive thinner ethoxyquin Viscoat 295 chosen of the present invention also correctability to the pungency of skin; The flexibility that tripropylene glycol diacrylate has had, can reduce composition viscosity, well adheres to promoter action in addition.
