Description

Technical Field

[0001] The invention belongs to the technical field of nail polish wearing jelly glue, and in particular relates to an OSG optical solid jelly glue used for nail polish wearing nail pieces. Background Art

[0002] In today's fashion trend, manicure has become an important way for many people to show their personality and beauty. Traditional manicure methods often take a long time to be performed in a nail salon, and products such as nail polish may cause certain damage to the nails. With the continuous advancement of technology, nail art wearing nail pieces has gradually become popular. However, there are three existing ways to wear nail pieces for manicure: 1. Self-adhesive bonding, which is easy to fall off and not firm. 2. Quick-drying glue, which hurts the nails. 3. Solid patch glue, which is cured by ultraviolet light and inconvenient to operate. So there are some shortcomings. For example, solid patch glue may have an unpleasant smell, which will not only cause discomfort to the user, but may also have a certain impact on the environment. In addition, jelly glue may not be strong enough after use, which may easily cause the nail piece to fall off, affecting the effect and durability of manicure. Moreover, quick-drying glue may cause damage to the nails when removed, which is not conducive to the health of the nails. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention aims to solve the problems of the existing adhesives for wearing nail tips, such as unpleasant odor, not being strong enough and easy to fall off, and easily damaging nails when removed. The disclosed optical solid jelly glue has the advantages of no unpleasant odor, being strong and long-lasting after use, having a long wearing time and not damaging nails after removal.

[0004] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: the present invention provides an OSG optical solid jelly glue for manicure wear nail pieces, comprising the following components in weight percentage: 20-30% N-acryloylmorpholine, 2-10% acrylic acid, 30-60% polyurethane resin, 5-15% isobornyl acrylate and 1-5% 1-hydroxycyclohexyl phenyl ketone.

[0005] Furthermore, the OSG optical solid jelly glue comprises the following components in weight percentage: 22-28% of N-acryloylmorpholine, 5-8% of acrylic acid, 40-50% of polyurethane resin, 8-12% of isobornyl acrylate and 2-4% of 1-hydroxycyclohexyl phenyl ketone.

[0006] Preferably, the OSG optical solid jelly glue comprises the following components in weight percentage: 25% N-acryloylmorpholine, 8% acrylic acid, 52% polyurethane resin, 12% isobornyl acrylate and 3% 1-hydroxycyclohexyl phenyl ketone.

[0007] Furthermore, the molecular weight of the polyurethane resin is 1000-5000.

[0008] Furthermore, the OSG optical solid jelly glue is prepared by the following steps:

[0009] S1. Accurately weigh the required N-acryloylmorpholine, acrylic acid, polyurethane resin, isobornyl acrylate and 1-hydroxycyclohexyl phenyl ketone according to weight percentage;

[0010] S2. Add the polyurethane resin into a stirring device to ensure that the resin is evenly dispersed, then slowly add N-acryloylmorpholine, acrylic acid, isobornyl acrylate and 1-hydroxycyclohexyl phenyl ketone, continue stirring to ensure that the pigment is evenly distributed in the glue, let the mixed glue react in a reactor for 18-24 hours, pre-coat with a thickness of 0.4-0.6mm using an optical coater, and reel up in a dark place to obtain a prefabricated coil, after the coil is slit, use a fully automatic die-cutting machine to punch out 4 layers of sandwich jelly glue, and after sorting, obtain the OSG optical solid jelly glue, and the above steps are illuminated by a yellow light until the packaging is completed.

[0011] Furthermore, in the step S2, the polyurethane resin is added and stirred for 5-8 minutes.

[0012] Preferably, in step S2, the polyurethane resin is added and stirred for 6 minutes.

[0013] Furthermore, in the step S2, the 1-hydroxycyclohexyl phenyl ketone is added and stirred for 8-15 minutes.

[0014] Preferably, in step S2, 1-hydroxycyclohexyl phenyl ketone is added and stirred for 12 minutes.

[0015] Furthermore, the OSG optical solid jelly glue is cured by irradiation with an ultraviolet light therapy lamp during use.

[0016] Furthermore, the power of the ultraviolet light irradiation is 3-10 mW / cm 2 .

[0017] Preferably, the power of the ultraviolet light irradiation is 8 mW / cm 2 .

[0018] Furthermore, the ultraviolet light irradiation time is 60-120s.

[0019] Preferably, the ultraviolet light irradiation time is 80 seconds.

[0020] The beneficial effects of the present invention are as follows: firstly, the jelly glue disclosed in the present invention does not have the unpleasant smell of UV glue, and will not make users feel uncomfortable during use, so that users do not need to endure the unpleasant smell while enjoying manicure, thereby providing a more comfortable use experience; secondly, the jelly glue disclosed in the present invention can be tightly combined with the nail plate and the nail after being irradiated by ultraviolet light to form a solid connection. The strength of the present invention is comparable to that of the original nail, and can effectively prevent the nail plate from falling off during daily activities, thereby ensuring the durability and stability of manicure; furthermore, the present invention has an ultra-long wearing time, and there is no need to frequently replace the nail plate, thus saving time and energy; finally, the jelly glue of the present invention remains soft after being removed, and will not cause any damage to the nail.
