Description

Technical Field

[0001] The present invention relates to the technical field of nail pieces for nail art, and particularly to a nail piece for nail art with antibacterial properties. Background Art

[0002] The decoration of nails is a popular way for beauty-loving ladies at present. Before the emergence of nail pieces, ladies usually applied nail polish and the like on the nail surface. Since the manifestation form of nail polish is not rich enough, later, the use of nail art stickers has gradually developed. Nail art stickers are a kind of nail decoration quite popular among young women in recent years and are indispensable tools for nail art lovers. They have unique usage methods and special effects that cannot be replaced by other nail tools.

[0003] As the most important organ of the human body, the hands are the most active every day and have the most contact with the outside world. The hands are the parts most prone to breeding bacteria. In fact, when the nail piece adheres to the fingernail, it is undeniable that the complexity of the finger is increased, making the area of the fingernail larger and more likely to nourish bacteria.

[0004] In order to reduce the positive impact of the nails with adhered nail pieces on finger bacteria, it is necessary to make corresponding improvements to the antibacterial properties of the nail pieces. Summary of the Invention

[0005] The purpose of the present invention is to develop a degradable plastic nail piece due to the current nail pieces not being environmentally friendly and not being degradable, causing environmental pollution. This kind of nail piece can not only have degradable properties, but also its strength and elasticity are completely comparable to those of the plastic materials currently used. Moreover, in order to improve the hygiene problem of the nail piece, it is given antibacterial properties.

[0006] Specifically, the present invention adopts the following technical solutions: A nail piece for nail art with antibacterial properties, the nail piece comprising: A nail piece body, as the main body, for carrying other layers; A pattern design layer, formed on the upper surface of the nail piece body, for presenting the pattern and design effect of the nail piece; An adhesive layer, formed on the lower surface of the nail piece body, for adhering the nail piece body to the nail; An antibacterial protective layer, formed on the pattern design layer, for antibacterial and protecting the pattern design layer; The bonding layer is obtained by photocuring using an antibacterial composition. The antibacterial composition of the bonding layer includes 50 - 58 parts of hyperbranched polyurethane acrylate, 5 - 8 parts of thioester derivatives, 3 - 9 parts of 5',5 - diallyl - 2,2'-biphenol, 1 - 5 parts of photoinitiator, 20 - 30 parts of aliphatic polyurethane acrylate oligomer, 20 - 25 parts of dipropylene glycol diacrylate, 10 - 20 parts of isobornyl methacrylate, 0.1 - 0.5 parts of wetting agent, and 0.2 - 1 part of leveling agent.

[0007] Preferably, the antibacterial protective layer is formed on the surface of the pattern design layer by photocuring a photocurable antibacterial coating.

[0008] Preferably, the photocurable antibacterial coating of the antibacterial protective layer includes, by weight: 40 - 50 parts of aromatic polyurethane acrylate prepolymer, 20 - 30 parts of hyperbranched polyurethane acrylate, 5 - 15 parts of polypropylene glycol diglycidyl ether diacrylate, 5 - 10 parts of bisphenol A type epoxy methacrylate, 35 - 40 parts of 1,6 - hexanediol diacrylate, 5 - 10 parts of organosilicon quaternary ammonium salt, 1 - 5 parts of photoinitiator, 0.5 - 1 part of leveling agent, and 0.1 - 0.5 part of nano - silica.

[0009] Preferably, the photocurable antibacterial coating further includes 0.1 - 0.5 part of nano - zinc oxide by weight.

[0010] Preferably, the pattern design layer is formed on the upper surface of the nail piece by spraying, printing, or vacuum coating.

[0011] Preferably, the preparation process of the organosilicon quaternary ammonium salt is as follows: Mix dodecyl dimethyl tertiary amine, acetic acid, and terminal epoxy - block polyether silicone oil in a ratio of 1:1:0.5 - 1, heat to 70 - 78°C under nitrogen protection, and carry out a reflux reaction for 3 - 7 hours to obtain the organosilicon quaternary ammonium salt.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By using a photocured bonding layer, an antibacterial effect is formed between the nail and the nail piece. By forming an antibacterial protective layer on the surface of the nail piece, not only can the hardness and wear resistance of the nail piece be improved to protect the nail piece, but also an antibacterial protective layer can be formed on the surface of the nail piece, which can effectively reduce the bacterial infection of the nail piece.
