Description

A kind of ultraviolet-curing paint and manufacture method thereof that is used for plastics
Technical field
The invention belongs to technical field of coatings, relate to a kind of ultraviolet-curing paint and manufacture method thereof that is used for plastics, particularly relate to a kind of ultraviolet-curing paint that is used for plastics with high rigidity and wear resisting property.
Background technology
It is efficient, energy-conservation, pollution-free that ultraviolet-curing paint has, and paint film layer is wear-resisting, hardness is high, strong adhesion, characteristics such as corrosion-resistant, has been widely used in furniture application, house decoration and printing ink etc.Since the These characteristics of ultraviolet-curing paint, the present finish paint that just is being applied to the plastic fittings of portable device, as the handset shell surface, portable computer external, toiletry bag casing etc.Spray this kind plastic component with ultraviolet-curing paint, can make its tough and hard wear resistant, the corrosion of sweat proof water or other chemical, the glossiness height, advantages such as usage period overlength, therefore, application in this regard is the focus that this kind coating promotes the use at present.
Traditional ultraviolet-curing paint that is used for woodenware, leather, metal etc., two or more that mostly adopt aliphatic urethane acrylate, polyester acrylate or epoxy acrylate are as main film forming substance, with 1 to 3 functional group reactions Acrylic Acid Monomer as diluting monomer, add a spot of auxiliary agent again and form, promptly adopt this kind method as CN1277232A, CN1297973A etc.Because the limitation of its composition and proportioning, when this kind coating was used for the finish paint of often frayed plastic device, its hardness and wear resistance were then inadequate.CN1436825A speaks of and add the anti-wear additive that accounts for gross weight 0.5~3% in coating system, this kind anti-wear additive model is BYK920, it is a kind of reactive auxiliary agent, can promote the cross-linking effect of resin or diluting monomer, therefore can increase the wear resistance of solidifying the back paint film to a certain extent, but be difficult to increase simultaneously largely the hardness and the wear resistance of paint film, therefore can not reach the service requirements of portable plastic device coating.
Summary of the invention
Technical problem to be solved by this invention is the defective that does not reach service requirements at the hardness of the portable plastic device coating of existing in prior technology paint film and wear resistance, a kind of ultraviolet-curing paint and manufacture method thereof that is used for plastics is provided, by in coating, increasing a kind of high-intensity hardness and anti-wear additive powder, can improve the fastness to rubbing and the hardness of ultraviolet-curing paint simultaneously, make it reach of the requirement of high-grade plastic device paint film coating.After being sprayed at frosting, use UV-irradiation, its solidifying film layer is the wear resisting property excellence not only, and the hardness height, ability sweat and the corrosion of general chemical, and the surface quality of coating is fabulous, is well positioned to meet the requirement of the coating of portable plastic device.
According to the present invention, the ultraviolet-curing paint that is used for plastics that is provided comprises matrix resin, reactive thinner, light trigger and solvent, it is characterized in that also comprising wear-resisting-hardness additive, this wear-resisting-hardness additive weight percent content in this coating is 0.1~8.0%, preferred 0.2~5.0%.Described wear-resisting-the hardness additive is that microhardness is at 500kgf/mm 2Above pressed powder.
In general the use, the hardness and the wear resisting property of portable plastic device paint film there is higher requirement than other coated.With respect to performances such as adhesive force of coatings, solvent resistances, the hardness of raising coating and the difficulty of wear resisting property are often bigger.
In the present invention, employing adds a certain amount of wear-resisting-hardness additive that is used to improve hardness and wear resistance in the total system of coating, described wear-resisting-material of hardness additive is the pressed powder with higher mechanical strength, when matrix resin and reactive thinner behind photocuring, wear-resisting-hardness additive powder is just sneaked into and is coated with in the rete, because this wear-resisting-hardness additive is the material with higher hardness and intensity, so just improve the whole physical and mechanical properties that is coated with rete greatly, greatly improved the hardness and the wear resistance of paint film.
In the outer photo-cured coating of purple of the present invention, so long as its microhardness satisfies the pressed powder of above-mentioned requirements, can as described wear-resisting-the hardness additive, for example, this wear-resisting-hardness additive can be for being selected from least a in carbide, nitride, oxide compound or the organic polymer.Preferably, described carbide is to be selected from least a in silicon carbide, zirconium carbide, norbide, aluminium carbide, iron carbide, the chromium carbide; Described nitride is to be selected from least a in titanium nitride, zirconium nitride, gan, aluminium nitride, the CaCl2; Described oxide compound is to be selected from least a in titanium dioxide, aluminum oxide, chromic oxide, stannic oxide, the silicon-dioxide; Described organic polymer is to be selected from least a in nylon, polyethylene wax, Poly Propylene Wax, polyvinyl chloride wax, the polycarbonate.

The former lacquer performance of above embodiment and made coating sees Table 1.
The performance of the paint film of coating behind ultraviolet light polymerization that each embodiment is made sees Table 2.
As can be seen from Table 2, do not add the abrasion resistance of the embodiment 1 of wear-resisting-hardness additive and have only 300 times, hardness is 2H, ethanol-tolerant test nondiscoloration.When adding the carborundum powder of 2.0g, its wear-resisting and hardness increases greatly, and the data results of embodiment 2 shows wear-resisting reaching 610 times, and hardness is 4H.The amount that continues the wear-resisting-hardness additive of increase reaches 8g, and this moment is wear-resisting and hardness amplification is little, but downtrending appears in sticking power, reaches 2B, and corrosion resistance nature also descends.Its reason is that wear-resisting and hardness additive has slackened the bonding force of body resin and ground.The inorganic additives of other kinds also reaches same effect, shown in embodiment 4,5.
Add a spot of organic additive and also can increase the wear-resisting and hardness that is coated with rete, shown in embodiment 6.
Change the amount of matrix resin or reactive monomer, add a spot of wear-resisting and hardness additive, can reach the effect that increases wear-resisting and hardness equally, but the minimizing of matrix resin or reactive thinner amount may cause the decline of paint film layer sticking power and corrosion resistance nature.Under equal conditions, the consequence that causes of the reduction of matrix resin amount can be more serious.Embodiment 7-10 has promptly shown this conclusion.
