Description
[technical field]
The invention belongs to high-molecular coating technical fields, and in particular to a kind of novel aqueous low gloss ultraviolet-curing paint
And its preparation and application.
[background technique]
The ultraviolet-curing paint of existing market, is substantially oiliness ultraviolet-curing paint, and ultraviolet-curing paint exists
Under action of ultraviolet light, the photoactive substance in system can generate active particle or group by photochemical reaction, thus primosome
Reactive resin in system carries out cross-linked polymeric, and then the paint film hardened, and most of product odour is big on existing market, paint film
Shrinkage is big, paint film is crisp and the features such as being not easy delustring, wherein ultralow dumb light product viscosity is excessively high, easy after-thickening is recycled, does not flow
It puts down, be not easy that dry, lingering taste is big, be not able to satisfy the market demand still, rare UV-curable waterborne coatings, are also deposited in the market
Admittedly containing the problems such as low, filling is poor, paint film easily returns white, not resistant to water, easy to crack, easy depainting, not anti-scratch.
[summary of the invention]
The purpose of the invention is to overcome the defect of existing coating, a kind of novel aqueous low gloss ultraviolet light solidification is provided
Coating.
Of the invention also provides a kind of preparation method of novel aqueous low gloss ultraviolet-curing paint.
Of the invention also provides a kind of application method of novel aqueous low gloss ultraviolet-curing paint.
A kind of novel aqueous low gloss ultraviolet-curing paint, by the material composition of following components by weight percent:
Preferably, the aqueous polyurethane acrylate A is 6 function low viscosity aliphatic urethane acrylates, Gu containing being
40%, aqueous polyurethane acrylate B are 3 functional aliphatic's urethane acrylates, Gu containing being 80%, watersoluble polyurethane acrylic acid
Ester C is 2 functional aliphatic's urethane acrylates, Gu containing the clear viscous shape liquid for 100%.Various functional polyurethane propylene
The flexibility that can improve system is combined in acid constituents, promotes paint film mobility.
Preferably, the hybrid reaction type diluent is ethoxyquin trimethylolpropane triacrylate and polyethylene glycol two
Acrylate, after being tested respectively in 7:3,6:4,5:5 ratio, the ratio of preferably 6:4 is prepared optimal.Ethoxyquin trihydroxy methyl
Three acrylate of propane and polyethylene glycol diacrylate rouge, belong to high-strength structure component, are bicomponent epoxy resin, no
Containing solvent, there is preferable shear strength and hardness.
Preferably, the flatting silica A is preferential to select that oil absorption is low, permeability is good and surface through processed fineness is 3-
6 microns of aerosil micro mist.
Preferably, more micropores and the distribution of particles of variation form the premise of its outstanding matte effect, are ideal
Spherical particle, do not influence the rheological property of coating completely, except with outstanding matte effect, enhance paint film elastic force (toughness)
Other than being influenced with hardness, low rheology, also has and improve scratch resistance, enhancing adhesive force, improve the soft degree in surface, weatherability
With gloss holding capacity.
Preferably, the photoinitiator A is 2- hydroxy-2-methyl -1- phenylacetone or 2- hydroxy-2-methyl -1- phenyl -
1- acetone, the photoinitiator b are 1- hydroxyl ring ethylphenyl ketone or 2,4, the oxidation of 6- trimethylbenzoy-dipheny
Phosphine.Particularly preferred photoinitiator is 2,4,6- trimethylbenzoy-dipheny phosphorous oxides (TPO), in low luster coating, because of powder
Expect more, paint film is thicker, need efficient ultraviolet initiator to reach solidification thoroughly, thus particularly preferably TPO do it is light-initiated
Agent.
Preferably, the dispersing agent is the acidic-group copolymer for containing 100% admittedly, what the defoaming agent contained admittedly for 100%
Polyetherpolysilicone transparency liquid, the levelling agent are the polyether-modified dimethyl silicone polymer for containing 100% admittedly.
Preferably, the aided initiating is tertiary amine acrylate, alkyl hydroxy amine, one in dimethylaminobenzoic acid ester
Kind.Can photoinitiator be preferably tertiary amine acrylate, oligomer and dispersing agent can be turned by liquid rapidly in promotion system
Solid-state is turned to, optical active group interaction can be improved the absorption to luminous energy, increase activity, while to a certain extent
Overcome the xanthochromia of product.
A kind of preparation method of novel aqueous low gloss ultraviolet-curing paint, comprising the following steps:
1) turning one's coat property of mixing, is answered into type diluent, dispersing agent, defoaming agent, levelling agent, flatting silica A, flatting silica B, light-initiated
Agent A, photoinitiator b, aided initiating sequentially add mixing under 300~450 revs/min of revolving speed stirrings, then with revolving speed 700~
900 revs/min obtain just stage mixture in stirring 15~25 minutes；
2) aqueous polyurethane acrylate A, B, C, are sequentially added to above-mentioned elementary section of mixing species, then with revolving speed 700~
After 900 revs/min are stirred 15~25 minutes, after filtering removal impurity, novel aqueous low gloss ultraviolet-curing paint is obtained.
A kind of application method of novel aqueous low gloss ultraviolet-curing paint, comprising the following steps:
After each component substep is mixed evenly, after thermal barrel is added after filtering, bucket inside courtyard temperature is added to 55~
After 60 DEG C, make coating material temperature uniformly and facilitate defoaming complete, can roller coating operation, the UV-curable waterborne bottom of timber floor
Paint is applied and is installed, and fills and leads up pore, straight and even smooth with the polishing of No. 320 sand paper, can roller coating in the plate face polished, by coating 9~
