Description

A kind of ultraviolet light fast solidification paint
The present invention relates to ultraviolet-curing paint.
Photo-curing material developed very rapid in recent years, many kinds occurred.Usually, light-cured resin is a kind of monobasic or binary mixture, and photosensitive diluent is binary or tertiary mixture.This makes that rigidity, toughness and the ageing resistance of photo-curing material are bad, and pungent odour is arranged.The photo-curing agent that tradition is used is the benzoin ether compounds, the main drawback of this photo-curing agent is: velocity of initiation is slow, cause the stable storing performance poor, flavescence is serious during polymerization, there is residual gas to emit after the decomposition, poor with the photosensitive resin consistency, and self synthesis technique complexity, synthesis material is poisonous.
Chinese patent CN1047104A has proposed a kind of ultraviolet rapid solidified tri compound optical fiber coatings, this invention coating adopts organosilicon, urethane, three kinds of dissimilar photosensitive resins of epoxy moderate as low-temperature performance, the pliability that light-cured resin has improved coating to a certain extent, the intensity height.But this coating mainly is suitable for doing optical fiber coatings, and is heat-resisting, and performances such as moisture-resistant wiping, gloss are also bad.
It is superior to the purpose of this invention is to provide a kind of fast setting, high gloss, high adhesive force, high tenacity, resistance toheat, shelf-stable, aging-resistant ultraviolet-curing paint.
To achieve the above object of the invention, coating of the present invention is made up of light-cured resin, photosensitive diluent, photosensitive properties-correcting agent, solidifying agent and flow agent; Wherein light-cured resin comprises vinylformic acid bisphenol type epoxy ester, vinylformic acid fragrance urethane and vinylformic acid fat urethane, and the parts by weight that they account in the coating are respectively 52-88 parts, 41-42 parts, 63-90 parts; Photosensitive diluent comprises Viscoat 295, pentaerythritol triacrylate, Triethylene glycol dimethacrylate, hexanediyl ester and ethylacrylic acid-2-ethoxylated ester, the parts by weight that they account in the coating are 42-61 parts respectively, 32-41 parts, 36-57 parts, 26-53 parts and 57-78 parts; Photosensitive properties-correcting agent comprises the Polycarbosilane acrylate, the weight percentage that it accounts in the coating is 8-15 parts, solidifying agent comprises ferrocene modification benzophenone photosensitizers, it accounts for, and parts by weight are 1.5-5 parts in the coating, flow agent comprises methyl acrylate and butyl acrylate copolymer, and the parts by weight that it accounts in the coating are 1-3 parts.
Light-cured resin is the main component of decision ultraviolet photocureable material physical and mechanical properties, and the many important performance to material has great influence as rigidity, viscosity, curing speed, sticking power, surface appearance, ageing-resistant performance etc.Contain epoxy group(ing), hydroxyl in the vinylformic acid bisphenol type epoxy ester molecule, these polar groups are to there being very strong sticking power by adhesion material, and film forming matter rigidity is big, and hardness is big, and ageing-resistant performance is good, but toughness is bad.In the vinylformic acid fragrance polyurethane molecular urethano group is arranged, its snappiness is good, and the film-forming rear surface is highly polished, strong adhesion, but have fragrant phenyl ring in the molecule, so ageing resistance is poor slightly, and high-and low-temperature resistance and impact property are good.In the vinylformic acid fat polyurethane molecular urethano group is arranged, thereby snappiness is good, the film-forming rear surface is highly polished, and does not have phenyl ring in the molecule, so ageing-resistant performance is outstanding especially.But the price of vinylformic acid fat urethane is the most expensive.The performance of comprehensive above three kinds of materials, the present invention has adopted above three kinds of photo-curing resin alloys, makes up for each other's deficiencies and learn from each other, and has overcome the shortcoming of one-component.
Use because photo-curing resin and the general viscosity of modifier thereof, are difficult to normal construction all than higher, so must add thinner, and this thinner is a kind of photosensitive diluent, promptly has in dilution function before solidifying and the solidification process to participate in the solidified function.Contain three activity double keys in Viscoat 295 that adopts among the present invention and the pentaerythritol triacrylate molecule respectively.Crosslinking reaction can take place in these three activity double keys under the effect of photosensitizers and UV-light, form the build network structure, increases the stiffness and ageing-resistant, the resistance toheat of this coating.These two reactive thinners play a trifunctional group cross-linking agent's effect in system.The Triethylene glycol dimethacrylate, contain two activity double keys in the hexanediyl ester molecule respectively, the key reaction of propagation can take place in these two activity double keys under the effect of photosensitizers and UV-light, form linear structure, increase the flexibility of coating, so these two reactive thinners play the effect of a bifunctional flexibilizing agent in system.Contain an activity double key in ethylacrylic acid-2-ethoxylated ester molecule, this activity double key can take place to send out under the effect of photosensitizers and UV-light with another pair key answers, thereby terminating chain increases.So this reactive thinner plays the effect of a simple function group chain terminator.The used photosensitive diluent of the present invention is water white transparency, scentless liquid.
Photosensitive properties-correcting agent adopts the Polycarbosilane acrylate to improve the thermotolerance of photoactive coating.Because contain the good Si-C key of thermostability in the Polycarbosilane acrylate,
Photo-curing agent consumption in prescription seldom but has critical influence to the many performances in the material, as polymerization velocity, stability in storage.Adopt ferrocene modification benzophenone to do the photo-curing agent among the present invention, overcome all shortcomings of using st-yrax ethers chemical combination to bring, it is few to have a consumption, and curing speed is fast, stability in storage height, the advantage of not yellowing during curing.
Flow agent adopts methyl acrylate and butyl acrylate copolymer, and good with the photosensitive resin consistency, the levelling effect is fine.
When preparing coating of the present invention, at first with the Polycarbosilane acrylate 60-80 ℃ down with ethylacrylic acid-2-ethoxylated esters dissolving, form solution A; Ferrocene modification benzophenone photosensitizers is dissolved with the Triethylene glycol dimethacrylate down at 40-60 ℃, form Solution H, methyl acrylate and butyl acrylate copolymer are diluted with pentaerythritol triacrylate under 40-60 ℃, form solution C, with A, H and C add in the reaction vessel respectively, stir after 2 hours, add vinylformic acid bisphenol type epoxy ester, add vinylformic acid fragrance urethane after half an hour, add vinylformic acid fat urethane again after half an hour, add Viscoat 295 and hexanediyl ester again after half an hour, be warming up to 45-55 ℃ after adding, stirring reaction 3 hours, discharging promptly gets product.
During use, be coated in above-mentioned coating on the article equably after, promptly curable with the UV-irradiation of wavelength 300-400nm, power 1-10kw 1-10 seconds.
Coating of the present invention is compared with traditional ultraviolet-curing paint, has that curing speed is fast, high gloss, high adhesive force, high tenacity, resistance toheat are superior, shelf-stable, aging-resistant advantage, are a kind of good ultraviolet-curing paints.
