Abstract

The invention relates to the field of paints in chemical industry, particularly a leveling-free ultraviolet curing primer. The leveling-free ultraviolet curing primer is composed of the following components in percentage by weight: 15-30% of epoxy acrylate, 10-30% of polyester acrylate, 20-30% of monomer, 10-25% of filler, 3-5% of photoinitiator, 0.2-0.5% of defoaming agent, 0.1-0.3% of leveling agent and 4-6% of anti-settling agent. The leveling-free ultraviolet curing UV primer can be directly sprayed.

Description

A kind of levelling ultraviolet cured primer of exempting from

Technical field

The present invention relates to chemistry painting industry field, particularly a kind of levelling ultraviolet-cured paint of exempting from.

Background technology

UV paint is photo-cured coating, and it is 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, to adopt medium density fiberboard be base material to cabinet family property in recent years, can improve and anti-ly subside, hardness, reduce costs etc.But general UV paint is this soft, and on the base material of high surface energy, levelling is very poor, traditional way is after mechanical grinding is processed, then sprays the transition of PU priming paint.Cause like this operation to increase, lengthen man-hour, uses PU paint, a large amount of organic solvent pollution atmosphere of release, and whole efficiency and benefit are not high.Especially in medium density fiberboard, paint, traditional way is to carry out acid activation, then paints transition with PU, and operation increases, and extend man-hour, has reduced the whole efficiency of application.

Summary of the invention

Technical problem to be solved by this invention be to provide a kind of can direct spraying, exempt from the ultraviolet light polymerization UV priming paint of levelling.

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

A levelling ultraviolet cured primer, is comprised of the component of following weight percent:

Epoxy acrylate 15 ~ 30%;

Polyester acrylate 10 ~ 30%;

Monomer 20 ~ 30%;

Weighting agent 10 ~ 25%;

Light trigger 3 ~ 5%;

Defoamer 0.2 ~ 0.5%;

Flow agent 0.1 ~ 0.3%;

Anti-settling agent 4 ~ 6%.

Further, described monomer is tri (propylene glycol) diacrylate (TPGDA), Viscoat 295 (TMPTA), 1, the mixture of 6-hexanediyl ester (HDDA), hydroxyethyl methylacrylate (HEMA), these selected monomer surface tension are little, they mix use can play reduction viscosity, improve sticking power, and can give the good levelling property of product and dilution property, play the effect that improves paint film.

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

Further; described light trigger is 1-hydroxyl-cyclohexyl-phenyl ketone (184), 2-hydroxy-2-methyl-1-phenyl-1-acetone (1173), (2; 4; 6-trimethylbenzoyl) mixture of diphenyl phosphine oxide (TPO); they mix use can play reduction viscosity; increase hardness and scrath resistance, improve the effect of sticking power.

Further, described defoamer is the conventional vinylformic acid defoamer of the art, is preferably BYK066N; Flow agent is the conventional vinylformic acid levelling agent of the art, is preferably BYK358N.

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

Further, the weight percent of each component of formula of this priming paint is preferably:

Epoxy acrylate 18 ~ 28%;

Polyester acrylate 12 ~ 28%;

Tri (propylene glycol) diacrylate 5 ~ 7%;

Viscoat 295 4 ~ 6%;

1,6 hexanediol diacrylate 4 ~ 6%;

Hydroxyethyl methylacrylate 5-7%;

Weighting agent 10-25%;

1-hydroxyl-cyclohexyl-phenyl ketone 0.5 ~ 2%;

2-hydroxy-2-methyl-1-phenyl-1-acetone 0.5 ~ 1%;

(2,4,6-trimethylbenzoyl) diphenyl phosphine oxide 1 ~ 2%;

Defoamer 0.2 ~ 0.5%;

Flow agent 0.1 ~ 0.3%;

Anti-settling agent 4 ~ 6%.

The present invention has following beneficial effect:

Compared with prior art, ultraviolet-cured paint of the present invention does not need levelling, and directly fast setting, does place without levelling line with waiting, can improve whole japanning efficiency, environmentally friendly, can reduce the discharge of organic solvent.
