Description

A kind of radium-shine roller coat UV matt white finish paints

Technical field

It is more particularly to a kind of radium-shine the present invention relates to a kind of coating of chemical field（Laser）Roller coat UV matt white finish paints.

Background technology

UV paints are photocureable coating, and it is to apply more extensive furniture lacquer at present, and main feature has：Processed by intensive ultraviolet photocuring, color stability, for a long time Chang Xin, environment friendly and pollution-free.UV paints are main to apply to plate fitment, and roller coat reality color finish paint is the difficult paint for doing of comparing, is extremely difficult to the mirror effect of PU paint, there is slivering weight, and levelling is poor, the problems such as richness is poor, does not reach the requirement of expensive goods.UV paint employs radium-shine in recent years（Laser）Roller application this method, solves slivering weight, and levelling is poor, the problems such as richness difference, reaches levelling degree high, and richness, with excellent mirror effect, can reach the plate face effect of PU reality color sprayings, be the optimal selection of expensive goods.Coating can be saved, product quality and production efficiency can be greatly improved.

The content of the invention

The technical problem to be solved in the present invention is to improve a kind of richness high, levelling degree high, without slivering print, with excellent mirror effect, can reach the radium-shine of PU spraying effects（Laser）Roller coat UV matt white finish paints.

In order to solve the above technical problems, the technical solution adopted in the present invention is：It is a kind of radium-shine（Laser）Roller coat UV matt white finish paints, by weight:Epoxy acrylate 20-30%, polyester acrylate 10-20%, monomer 20-30%, titanium dioxide（TiO2）8-10%, aerosil delustering agent 5-15%, light trigger 4-5%, levelling agent 0.1-0.5%, defoamer 0.1-0.3%, dust-proofing agent 0.5-1%, dispersant 0.5-2%.

Further：Above-mentioned radium-shine（Laser）In roller coat UV matt white finish paints, polyester acrylate used has extraordinary pliability, and shrinkage can effectively reduce the shrinkage stress of system, have good booster action to the raising of adhesive force than relatively low, and extinction is relatively good, contributes to effect.Epoxy acrylate has extraordinary film forming and low-down shrinkage as matrix resin, and relatively low viscosity plays reduction paint viscosity, workability is reached requirement.So, the present inventor's polyester acrylate commercially available to multiclass and epoxy acrylate are carried out after experiment gropes, the following several commercially available polyester acrylates of selection, such as the 6316 of Changxing, the 2022 of section field, 2381 etc. of Baeyer, the following several commercially available epoxy acrylates of selection：Such as the 6105-80 of three wood, the 622A-80 in Changxing, section Ningde 3215 etc., because these polyester acrylates and epoxy acrylate are commercially available, what those skilled in the art commonly used, the specific composition of each of which commodity is all fixed, thus only need to select this several commercially available polyester acrylates and epoxy acrylate in it is each any one, buy back come according to formula consumption be added to it is radium-shine（Laser）The present invention is capable of achieving in roller coat UV matt fine flour paint formulas.Monomer used is tri (propylene glycol) diacrylate（TPGDA）, dipropylene glycol diacrylate（DPGDA), trimethylolpropane trimethacrylate（TMPTA）, 1,6 hexanediyl esters（HDDA）, ethoxylated trimethylolpropane triacrylate (EO-TMPTA), hydroxyethyl methacrylate（HEMA one or more in), play reduction viscosity, increase hardness and resistance to scraping, improve the effect of adhesive force.Light trigger used is 1- hydroxyls-cyclohexyl-phenyl ketone（184）, 2- hydroxy-2-methyl -1- phenyl -1- acetone（1173）, 2,4,6 (trimethylbenzoyl) diphenyl phosphine oxides（TPO）, phenyl it is double（2,4,6- trimethylbenzoyls）Phosphine oxide（819）In one or more.So titanium dioxide（TiO2）Be rutile type titanium white, anatase thpe white powder one or two.Described flatting silica is aerosil flatting silica, such as OK-500, Grace 2105.Described levelling agent is efficient acrylic acid levelling agent, such as BYK-358N；Described defoamer is efficient acrylic acid defoamer, such as BYK-055, BYK-020, and described anti-settling agent is one or more in efficient organobentonite, Tissuemat E, aerosil, such as M-5, moral modest 201；Described dispersant is efficient acrylic acid wetting dispersing agent, such as BYK-2009.

Compared with prior art, the present invention by weight:Epoxy acrylate 20-30%, polyester acrylate 10-20%, monomer 20-30%, titanium dioxide（TiO2）8-10%, aerosil delustering agent 5-15%, light trigger 4-5%, levelling agent 0.1-0.5%, defoamer 0.1-0.3%, dust-proofing agent 0.5-1%, dispersant 0.5-2%.Be fabricated to for above-mentioned material radium-shine by the painting method commonly used according to those skilled in the art（Laser）Roller coat UV matt white finish paints, with radium-shine (laser）On base material, coating weight directly solidifies roller coat roller in 30-50g/ ㎡, 50 DEG C of levelling 1-2min clocks, can greatly improve production efficiency, and film forming coating weight is low, great reduces cost.Splendid mirror effect can be obtained after solidification, levelling high, richness high, without slivering, can reach the surface effect of PU sub-gloss varnish.
