Technical field
The present invention relates to technical field of coatings more particularly to a kind of water fever light dual-cured coatings.
Background technique
Ultraviolet-curing paint is that the energy of ultraviolet light is utilized to cause the low molecule performed polymer in coating or oligomer and work
Polymerization and cross-linking reaction between the monomer molecule of reactive diluent obtain hardening paint film, chemical essentially by being formed
Key realizes chemical seasoning, has no or low VOC emission, the saving energy, curing rate fast, raw compared with traditional heat cure effect
Produce the high-efficient, advantages such as be suitble to flow line production, solidification temperature low.
Since UV-curing technology has the above advantages, so powerful vitality is shown in production application,
However, there is also following both sides disadvantages for ultraviolet light solidification: first is that during ultraviolet light solidification, solidification is limited to ultraviolet light
Penetration depth, solidify especially for coating dash area incomplete；In coating ultraviolet light is absorbed and hindered containing a large amount of
It is incomplete to also result in deep cure for filler；Second is that oxygen inhibition effect is serious in UV curing system, the inhibiting effect of oxygen is normal
Cause lower layer cured, but surface is still uncured and tacky.Oxygen inhibition effect not only extends the ultraviolet light cured time, but also
The important performances such as hardness, wearability, scratch resistance of paint film after damage solidifies.
The shortcomings that in terms of two above, becomes and restricts the crucial barrier that UV-curing technology is promoted and applied to every profession and trade
Hinder.Research finds to introduce heat cured system in UV curing system, and so that coating is formed ultraviolet-heat dual UV curable paint can
The shortcomings that overcome above-mentioned single ultraviolet curing type coating, this becomes the research direction of coating in recent years, while coating is hard
Degree, mechanical performance and impact resistance are still urgent problem to be solved in industry.
Summary of the invention
It is an object of the invention to: a kind of water fever light dual-cured coating is provided, can make up for it simple UV light
Change the deficiency of coating, guarantee coating can completion of cure, while also adding the hardness, impact resistance and mechanical performance of coating.
The technical solution adopted by the invention is as follows:
To achieve the above object, the present invention provides a kind of water fever light dual-cured coating, in parts by weight, the coating packet
It includes following raw material: 50~80 parts of ultraviolet curing prepolymer, 30~60 parts of heat cure performed polymer, 0.3~2 part of curing agent, diluting
25~40 parts of agent, 0.3~2 part of photoinitiator, 0.5~3 part of auxiliary agent, 10~40 parts of silicon carbide, 20~35 parts of intensive.
Preferably, the ultraviolet curing prepolymer is selected from polyurethane acrylate prepolymer body, epoxy acrylate pre-polymerization
One of body or compound.
Preferably, the heat cure performed polymer is selected from polyurethane polyol.
Preferably, the curing agent is selected from toluene di-isocyanate(TDI), and poly ethyldiol modified HDI trimer and sulfonic group change
Any one in the HDI trimer of property.
Preferably, the diluent is selected from styrene, methyl methacrylate, diallyl phthalate, three second two
One of alcohol diacrylate, Triallyl isocyanurate and ethoxyquin pentaerythritol tetraacrylate are a variety of.
Preferably, the photoinitiator is selected from benzoin dimethylether, alkyl arone derivative, 2,4,6- trimethylbenzoyls
One or more of base diphenyl phosphine oxide.
Preferably, the auxiliary agent includes levelling agent, dispersing agent, defoaming agent and adhesion promoter.
Preferably, the weight ratio of the levelling agent, dispersing agent, defoaming agent and adhesion promoter is (2~4): (1~
3): (1.2~2): (0.5~1.5).
Preferably, the intensive includes talcum powder, barium sulfate and nano aluminium oxide.
Preferably, the weight ratio of the talcum powder, barium sulfate and nano aluminium oxide is (3~5): (1.5~3): (0.5~
2)。
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. ultraviolet curing prepolymer of the invention first forms UV curing system with photoinitiator, then heat cure is pre-
Aggressiveness and curing agent form heat cured system, and two kinds of systems, which combine, forms hot light dual-cured coating, can make up simple purple
The deficiency of outer photocureable coating, enables coating completion of cure, and the layer of lacquer surface property of formation is more preferable.
2. joined silicon carbide in the present invention, silicon carbide can be grafted in polyurethanes performed polymer, and the two cooperates,
Since silicon carbide has high rigidity and excellent wearability and heat-resisting quantity, to considerably increase the hardness of polymer, resistance to punching
Hitting property and mechanical performance.
3. it joined talcum powder, barium sulfate, nano aluminium oxide in the present invention to cooperate as intensive, it can be further
Increase hardness, impact resistance and the mechanical performance of coating of the present invention.
