Abstract

The invention relates to the field of coatings, particularly to a transparent ultraviolet-curing edge-sealing primer coating. The transparent ultraviolet-curing edge-sealing primer coating is characterized by comprising components in percentage by mass as follows; 23-53% of resin, 20-40% of monomers, 10-25% of a filler, 4-7% of a photoinitiator, 0.2-0.5% of an antifoaming agent, 0.1-0.3% of a leveling agent and 5-8% of an anti-setting agent; and the resin is a mixture of epoxy acrylate, modified epoxy acrylate and modified polyurethane acrylate. The coating is simple in process, low in viscosity and good in leveling property, and edges can be sealed with no PU (poly urethane) or PE (poly ethylene) primer required.

Description

A kind of ultraviolet light polymerization edge sealing transparent priming coating

Technical field

The present invention relates to paint field, particularly a kind of ultraviolet light polymerization edge sealing transparent priming coating.

Background technology

UV paint is photo-cured coating, and it is one of the furniture lacquer more widely of application at present, and principal feature has: through intensive ultraviolet photocuring, process, color and luster is stable, for a long time Chang Xin.So be widely used at aspects such as cabinet family properties, can improve and anti-subside, hardness, reduce costs etc., but restricting the efficiency of producing on the edge sealing of cabinet family property.On edge sealing, general UV paint reduces viscosity and reaches spraying requirement because needs add solvent, and will increase levelling line, and paint film irritating smell is large, and environmental pollution is serious, causes UV paint Difficulty.Traditional way is to carry out edge sealing with PU or PE priming paint.Cause like this operation to increase, lengthen man-hour, reduced the whole efficiency of application.

Summary of the invention

It is simple that technical problem to be solved by this invention is to provide a kind of operation, good leveling property, the ultraviolet light polymerization edge sealing transparent priming coating that viscosity is low.

Technical problem to be solved by this invention is achieved by the following technical programs:

Described resin is the mixture of epoxy acrylate, modified epoxy CALCIUM ACRYLATE, modified polyurethane CALCIUM ACRYLATE.

Further, described resin account for formula gross weight mass percent be: epoxy acrylate 5 ~ 15%, modified epoxy CALCIUM ACRYLATE 15 ~ 30%, modified polyurethane CALCIUM ACRYLATE 3 ~ 8%.Epoxy acrylate used is standard epoxy acrylate.Modified epoxy CALCIUM ACRYLATE is the conventional modified epoxy CALCIUM ACRYLATE of the art, YTM2085 as beautiful in refined painting, it has extraordinary snappiness as matrix resin, and shrinkability is lower, the string stress that can effectively reduce system, has good effect to the raising of sticking power.Modified urethane acrylate is selected the conventional modified urethane acrylate of the art, YTM5200 as beautiful in refined painting, it is as assisted resin, there are extraordinary wettability and low-down shrinkability, lower viscosity plays and reduces paint viscosity, and selected resin defoaming is good, froth breaking, makes workability reach requirement fast.

Further, described monomer is at least one in tri (propylene glycol) diacrylate (TPGDA), Viscoat 295 (TMPTA), 1,6 hexanediol diacrylate (HDDA), hydroxyethyl methylacrylate (HEMA); They can play reduction viscosity, improve sticking power, and can give the good levelling property of product and dilution property, improve the effect of paint film.

Further, described weighting agent is at least one in talcum powder, transparent powder, Zinic stearas.

Further, described light trigger is 1-hydroxyl-cyclohexyl-phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-1-acetone, (2,4; 6-trimethylbenzoyl) at least one in diphenyl phosphine oxide; they play reduction viscosity, increase hardness and scrath resistance, improve the effect of sticking power.

Further, described defoamer is vinylformic acid defoamer, BYK141 as conventional in the art, and flow agent is the agent of vinylformic acid levelling, preferably conventional BYK-333 or the DEGO450 of the art.

Further described anti-settling agent is at least one in organobentonite, polyethylene wax, aerosil.

The present invention has following beneficial effect:

In the middle of the present invention, this priming paint can be painted on ground, by ultraviolet light polymerization, reduce operation, man-hour, efficiency improves greatly.And do not needing to add under the prerequisite of any solvent, dope viscosity of the present invention is low, and levelling line is good, without PU or PE priming paint in the situation that, carry out edge sealing.
