Description
Technical Field
The invention belongs to the field of UV (ultraviolet) coatings, and particularly relates to a fluffy skin-touch scratch-resistant coating and a preparation method thereof.
Background
The UV light curing technology is applied to a plurality of fields by virtue of its "5E" advantages of high efficiency (efficiency), wide adaptability (Energy), economy (economic), energy Saving (Energy Saving), and Environmental protection (Environmental Friendly), including the field of UV light curing paint. At present, the UV light-cured coating is widely applied to coating of shells of electronic products such as mobile phone flat plates and the like, surface films of household appliances such as television washing machines and the like, wood-plastic floors, cosmetics and the like. With the improvement of living standard of people, the requirement on the appearance of daily necessities is higher and higher, and parts frequently touched by hands are required to have the effect of elastic hand feeling, so that smooth feeling similar to skin touch is provided for people, and the skin-feel paint is produced accordingly.
Patent CN 113122125A discloses a UV skin-feel wood coating, a preparation method and an application thereof, wherein the formula thereof is as follows: 10-40 wt% of mixed oligomer of bifunctional elastic polyurethane acrylate, bifunctional polysiloxane polyurethane acrylate and hexafunctional polyurethane acrylate, 50-80 wt% of reactive diluent, 0.1-5 wt% of functional additive, 1-10 wt% of functional filler and 1-10 wt% of photoinitiator. The scratch-resistant effect of the coating is realized by adding self-repairing elastic polyurethane, the surface of the self-repairing resin can be repaired by heating after being scratched, but the scratch-resistant effect of the coating is poor.
Patent CN 113402968A discloses a method for developing a novel UV ultraviolet light curing skin-feel paint, which comprises the following formula: 15-45 wt% of 4-8 functionality polyurethane acrylate, 5-20 wt% of monofunctional reactive diluent, 10-30 wt% of bifunctional reactive diluent, 20-40 wt% of trifunctional reactive diluent, 5-15 wt% of matting powder, 2-8 wt% of photoinitiator and 1-3 wt% of slipping agent. The formula adopts high-functionality elastic polyurethane as a main body to improve the scratch resistance, but the skin feel effect is difficult to obtain only by using a single slipping agent, the compatibility of the slipping agent and resin is reduced during curing, and the yield is not high.
Patent CN 112694828A discloses a UV LED ultraviolet light curing skin-feel paint, a preparation method thereof and a skin-feel material. 50-70 wt% of trifunctional polyurethane resin, 13-18 wt% of acryloyl morpholine, 6-10 wt% of extinction powder, 4-6 wt% of photoinitiator, 8-12 wt% of wool powder and elastic powder, and 0.8-1.2 wt% of wetting dispersant and hand feeling agent. The main resin used in the patent is trifunctional polyurethane acrylic resin, which has good flexibility effect but inferior scratch resistance to high-functional resin; the wetting dispersant is BYK2013, the hand feeling agent is Tego410, and the two auxiliaries have good powder dispersing and anti-settling effects and provide certain smoothness, but have little skin feeling improvement effect.
The above patents all depend on the mutual matching of high-low-functionality resin, and microscopically, the low-functionality resin is embedded into the high-functionality resin gaps to form a compact network structure during curing, so that the performances of high hardness, high wear resistance and the like achieved by the crosslinking density are improved. However, the mechanical properties of the resin obtained by curing the resin alone are far inferior to those of the resin obtained by adding inorganic fillers such as silica and titanium dioxide. Meanwhile, the high-functionality resin has large shrinkage rate, and the shrinkage of the high-functionality resin can be reduced after inorganic powder is filled, so that the surface dryness and the appearance of a cured film are improved. However, the difficulty of adding inorganic powder at present is that no proper dispersant and light-cured resin are available, the shape, size and particle size of the inorganic powder are not uniform, and if the inorganic powder cannot be stably and uniformly dispersed in the resin, the particles are protruded during curing film forming, and the scratch resistance is reduced.
To sum up, the scratch resistance of the existing ultraviolet curing field skin-friendly coating is generally not high, and in the face of increasingly intense market competition, a single skin-friendly coating cannot meet the market demand, so that a product which has multiple performances of skin-friendly, flexible, scratch-resistant, non-sticky return, good film-forming property, good adhesion, low viscosity and the like is needed to meet the demands of different use occasions.
Disclosure of Invention
In view of the defect of poor comprehensive performance of skin-feel paint in the prior art, the invention aims to provide the villous skin-feel scratch-resistant paint and the preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a frizzled skin-feel scratch-resistant coating which comprises the following components in percentage by mass: 30-80 wt% of light-cured resin, 1-5 wt% of photoinitiator, 15-50 wt% of solvent, 2-5 wt% of filler, 1-5 wt% of wetting dispersant and 1-5 wt% of surfactant.
Preferably, the light-cured resin is a mixture of high-functionality urethane acrylate and low-functionality aliphatic urethane acrylate. The high functionality urethane acrylate comprises one or more of 10 functionality aliphatic urethane acrylate, 9 functionality aromatic urethane acrylate, 15 functionality hyperbranched urethane acrylate, 9 functionality aliphatic urethane acrylate, and 6 functionality aliphatic urethane acrylate, and the low functionality aliphatic urethane acrylate comprises one or more of 3 functionality aliphatic urethane acrylate, monofunctional aromatic urethane acrylate, monofunctional aliphatic urethane acrylate, and 2 functionality aliphatic urethane acrylate. Wherein, the high-functionality polyurethane acrylate comprises one or more of CN-8000NS, sarbox SB400, 4600, 7903A and RJ-031, and the low-functionality polyurethane acrylate comprises one or more of CN-996AN, CN-736, N3D-I2809, N3D-C269, 7130B, 37280-5, CN-1072 and CN-996 AN.
Preferably, the photoinitiator comprises one or more of Benzophenone (BP), 2-hydroxy-2-methylphenylacetone (1173), 2,4, 6-trimethylbenzoyl-diphenylphosphine oxide (TPO), 1-hydroxycyclohexylphenylketone (184), 2-Isopropylthioxanthone (ITX).
Preferably, the solvent comprises one or more of butyl acetate, ethyl acetate, n-butyl acetate, butanone, n-butanol and propylene glycol methyl ether acetate.
Preferably, the filler comprises a mixture of silica powder, micron-sized talc powder or micron-sized wax slurry; wherein, the micron-sized (1-10 μm) talcum powder or the micron-sized (1-10 μm) wax slurry accounts for 50-90% of the total mass of the filler, and the silicon dioxide powder accounts for 10-50% of the total mass of the filler. The silicon dioxide powder is prepared by a precipitation method or a gas phase method.
The purpose of selecting the micron-sized silicon dioxide powder is to improve the wear resistance of the coating, but the addition of the silicon dioxide can cause the hand feeling of the coating to be reduced, so the addition of the talcum powder can improve the smooth feeling of the coating, and meanwhile, the talcum powder can also provide certain hardness. According to the experiment, the mixture of the talcum powder and the silicon dioxide 3 can reach the hardness and the wear resistance of the pure silicon dioxide under the same weight, but the scratch resistance and the hand feeling are better than those of the pure silicon dioxide.
Preferably, the wetting dispersant comprises one or more of BYK-2250, BYK-2159, BYK-111, BYK-2008 and BYK-2013. The dispersant used in the invention is a special silicon oxide dispersant from Pico, and has the greatest advantage of strong compatibility, especially the dispersant can also disperse talcum powder and wax slurry. Other companies such as the dispersant such as Dow, cherokee blue, modest and high, have also tried, the process tolerance is not like bike, the phenomena of flocculation, sedimentation and the like can occur when different grades of silicon oxide powder are changed, some of the silicon oxide powder can not be compatible with resin, and the dispersant for dispersing talcum powder can be added when talcum powder is added.
The hardness of the paint can be increased by adding the filler, and through the combined action of the filler and the wetting dispersant, the smooth hand feeling is provided, and the fluffy skin feeling effect is also apparent. The selected filler is a mixture of silicon dioxide and talcum powder or wax slurry, the number of the fillers is three, the price of the first micron-sized talcum powder is lower than that of the silicon dioxide, and the cost is reduced; secondly, although the single silicon dioxide can improve the hardness and the wear resistance of the coating, the hand feeling of the coating is slightly rough compared with the skin of a baby, and the coating has more delicate hand feeling and matte fluff feeling in appearance after the talcum powder or wax slurry is added; and thirdly, the introduction of a proper dispersant can completely wrap the silicon dioxide powder and the talcum powder, so that the silicon dioxide powder and the talcum powder can directly form relatively stable space position force and electrostatic repulsion force and are microscopically and uniformly distributed in a high molecular chain segment. The anti-settling property is good, and the anti-settling agent can be kept stand for two months in a dark place or can be continuously used for more than 6 months without generating settling.
Preferably, the surfactant comprises one or more of BYK-370, tego-410, BYK-320, BYK-345, BYK-310, BYK-333 and BYK-350.
The invention also provides a preparation method of the velvety skin-feel scratch-resistant coating, which comprises the following preparation steps:
step 1: weighing a solvent and a light-cured resin, stirring until the solvent and the light-cured resin are completely dissolved, and diluting the resin;
and 2, step: adding wetting dispersant and filler, and fully stirring;
and step 3: adding a photoinitiator and a surfactant, and continuously stirring;
and 4, step 4: filtering to obtain the villus skin-touch scratch-resistant coating which is fully mixed and uniformly dispersed.
Preferably, in step 1, the stirring rate is 500 to 700r/min, preferably 600r/min.
Preferably, in the step 2, the stirring time is 40-80min, preferably 60min; the rotating speed of the rotor is 1200-3000 r/min.
Preferably, in the step 3, the stirring speed is 200-400r/min, preferably 300r/min; the stirring time is 20-40min, preferably 30min.
Preferably, in step 3, after the addition of the photoinitiator and the surfactant, the solvent is added again to the set mass fraction, i.e., the original weight (to replenish the lost solvent). When preparing the coating, attention is paid to adding the solvent once later, so as to fill up the part of the solvent volatilized due to the high-speed rotation of the rotor.
Preferably, in step 4, the filtration is performed by using a 500-600 mesh sieve, preferably a 400 mesh sieve.
Compared with the prior art, the invention has the following beneficial effects:
(1) The main body resin is high-functionality and low-functionality mixed elastic polyurethane acrylate, and provides smooth skin feeling and certain hardness. Meanwhile, the low-functionality polyurethane acrylate has good wrapping property, and the wetting dispersant is matched for use, so that the inorganic powder can be perfectly wrapped, and the scratch resistance of the coating is improved. The filler is talcum powder for improving hand feeling and silicon dioxide powder for improving mechanical properties such as wear resistance, scratch resistance, hardness and the like, and the smoothness and the wear resistance of the coating are further improved. The surfactant used in the formula has the effects of reducing the surface tension of the coating and improving the leveling property, and can also improve the adhesive force of the coating to plastic substrates such as PET, PC, PMMA, PP, PE, ABS and the like.
