Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a white antibacterial coating for UV laser roller coating.
Background
The antibacterial coating has broad-spectrum and long-acting antibacterial effect, can effectively inhibit the growth of gram-positive bacteria and gram-negative bacteria, and has an antibacterial rate of over 99 percent for conventional bacteria such as escherichia coli, staphylococcus aureus and the like. The antibacterial coating is prepared by adding an antibacterial agent into the coating so that the coating has antibacterial performance. When the antibacterial coating is used in public places, the bacterial content in the public places can be reduced, so that the probability of cross infection and contact infection is reduced; when the antibacterial agent is used in a household environment, the antibacterial agent can effectively reduce the bacterial density of articles such as furniture and the like, and optimize the living environment of people.
The UV paint is an ultraviolet light curing coating, is a furniture paint which is widely applied at present, and is mainly characterized in that: through the strong ultraviolet light curing treatment, the color is stable, the color is new for a long time, and the environment is protected. The UV paint is mainly applied to plate-type furniture, and the white finish paint is a paint which is difficult to make in the UV paint, has poor fullness, poor surface leveling and poor antibacterial effect; the construction is difficult to control, the loss of the spraying construction is large, the efficiency is not high, the spraying coating film is thick, and the cost is high.
Disclosure of Invention
Aiming at the situation, in order to make up for the existing defects, the invention provides the UV laser roller coating white antibacterial coating which is suitable for coating the plate-type furniture, has good leveling property and high fullness, and has the effects of broad-spectrum and long-acting resistance.
The invention provides the following technical scheme: the invention provides a UV laser roller coating white antibacterial coating which comprises the following components in percentage by weight: 10-20% of bifunctional modified epoxy acrylate resin, 5-20% of polyester acrylate resin, 0-15% of aliphatic bifunctional polyurethane acrylate resin, 20-30% of functional monomer, 4-7% of photoinitiator, 0.1-0.5% of defoaming agent, 0.1-0.4% of wetting and leveling agent, 20-30% of titanium dioxide, 0-14% of matting powder, 0-2% of wax powder, 1-2% of dispersing agent, 0.05-0.5% of anti-settling agent and 0.5-1% of antibacterial agent.
Further, the functional monomers are at least two of dipropylene glycol diacrylate, hexanediol diacrylate and trimethylolpropane triacrylate, and since the solubility, flexibility, dullness, fullness and curing speed of different monomers are different, the properties of a single monomer are difficult to balance, so that at least two functional monomers are selected.
Further, the photoinitiator is a mixture of a-hydroxy isopropyl benzophenone, a-hydroxy cyclohexyl benzophenone, 2,4, 6-trimethylbenzoyl-diphenyl phosphine oxide and phenyl bis (2,4, 6-trimethylbenzoyl) phosphine oxide.
Further, the wetting leveling agent is one or two of an acrylic leveling agent and a polysiloxane-polyether copolymer.
Further, the matting powder is silicon dioxide matting powder.
Further, the dispersant is one or both of a copolymer solution of the acid group-containing interpolymer and a structured acrylic copolymer solution.
Further, the antibacterial agent is a silver ion antibacterial agent.
Further, the defoamer is an acrylate polymer and mixtures thereof.
The invention with the structure has the following beneficial effects: the UV laser roller-coated white antibacterial coating provided by the invention is suitable for coating the white finish paint of the panel furniture, and has the following advantages compared with the existing white finish paint:
(1) the silver ion antibacterial agent is added into the UV laser roller coating white finish, the cell walls of bacteria are negatively charged due to the positive charge of the silver ions, and the silver can be adsorbed on the cell walls of the bacteria to cause uneven positive and negative electricity so as to break the bacteria, thereby achieving the antibacterial effect; meanwhile, silver ions can penetrate into the cell and destroy the intracellular structure (mitochondria, vacuole, ribosome) and biomolecules (protein, lipid and DNA), thereby destroying the activity of cell synthase and further leading the microorganism to lose the division and proliferation capacity; and the silver ions have strong adsorption and fixation effects on the viruses, can be combined with certain proteins on the surfaces of the viruses to influence the interaction between the viruses and cell receptors, so that the combination of the viruses and host cells is blocked, and the viruses are prevented from invading the cells, so that the added silver ion antibacterial agent has the effects of broad-spectrum and long-acting resistance.
(2) Through the matching use of the difunctional modified epoxy acrylate resin, the polyester acrylate resin, the aliphatic difunctional urethane acrylate and the functional monomer, and the matching of a proper amount of the dispersing agent and the wetting and leveling agent, the UV laser roller coating white finish achieves the surface effects of spraying the PU paint and the UV shower coating paint;
(3) the matting powder with different proportions is matched to meet the requirements of the plate-type furniture on different glossiness.

As can be seen from the above table, the UV laser roller-coating white antibacterial coating provided by the invention has an antibacterial rate of over 99.99% on escherichia coli and staphylococcus aureus, has a flat and smooth surface, and can achieve the surface effects of PU (polyurethane) paint spraying and UV curtain coating paint spraying; and its glossiness (60 deg.) can be 10-100%
Comparative example 1 differs from example 1 in whether an antibacterial agent is added: the scheme (example 1) of adding the antibacterial agent has the sterilization rate of over 99.99 percent on escherichia coli and staphylococcus aureus, and the scheme (comparative example 1) of not adding the antibacterial agent has no antibacterial property, which indicates that the antibacterial agent has obvious antibacterial effect.
Comparative example 2 also differs from example 5 in whether an antimicrobial agent is added: the antibacterial rate of the scheme (example 5) of adding the antibacterial agent to escherichia coli and staphylococcus aureus reaches more than 99.99 percent, the scheme (comparative example 2) of not adding the antibacterial agent has no antibacterial property, and the antibacterial effect is further illustrated by adding the antibacterial agent.
Comparative example 3 differs from example 1 in whether or not a difunctional modified epoxy acrylate resin is added: the scheme of adding the difunctional modified epoxy acrylate resin (example 1) has excellent fullness, the scheme of not adding the difunctional modified epoxy acrylate resin (comparative example 3) has poor fullness, and the difunctional modified epoxy acrylate resin has an obvious effect on the fullness improvement.
Comparative example 4 the difference in example 1 is whether a polyester acrylate resin is added:
the scheme (example 1) of adding the polyester acrylate resin has a flat and smooth surface effect without roll marks, and the scheme (comparative example 4) of not adding the polyester acrylate resin has slight roll marks, which shows that the polyester acrylate resin has an obvious effect on improving the flatness.
The difference between comparative example 5 and example 5 is whether or not the difunctional modified epoxy acrylate resin is added, the case of adding the difunctional modified epoxy acrylate resin (example 5) is excellent in fullness, and the case of not adding the difunctional modified epoxy acrylate resin (comparative example 5) is poor in fullness, which further shows that the difunctional modified epoxy acrylate resin has an obvious effect on the fullness improvement.
The difference between comparative example 6 and example 5 is whether polyester acrylate resin is added or not, the scheme (example 5) with polyester acrylate resin is smooth and has no roll mark, and the scheme (comparative example 6) without polyester acrylate resin has slight roll mark, further showing that polyester acrylate resin has obvious effect on improving the flatness.
Comparative examples 7 and 8 are different from example 5 in that whether or not the aliphatic bifunctional urethane acrylate resin is added, the gloss is remarkably matte with the addition of the aliphatic bifunctional urethane acrylate resin (example 5), and the gloss is brighter without the addition of the aliphatic bifunctional urethane acrylate resin (comparative examples 7 and 8).
In conclusion, the UV laser roller-coating white antibacterial coating provided by the invention can be suitable for coating the white surface of the plate-type furniture, and firstly, the sterilization rate of the UV laser roller-coating white antibacterial coating to escherichia coli and staphylococcus aureus is more than 99.99% by adding the silver ion antibacterial agent; secondly, matching the difunctional modified epoxy acrylate resin, the polyester acrylate resin, the aliphatic difunctional urethane acrylate and the functional monomer, and matching a proper amount of dispersant and a wetting and leveling agent to ensure that the UV laser roller coating white finish achieves the surface effects of spraying PU paint and UV shower coating paint; and thirdly, matching with different proportions of matting powder to meet the requirements of the plate-type furniture on different glossiness.
