Conventionally, ABS (acrylonitrile butadiene styrene) or PMMA (acrylic resin) is used as a raw material for producing artificial nail materials, which are very hard, are not adhered after being worn on hands, cause discomfort to people, influence the wearing retention time due to the hardness, and have low transparency, and the ABS contains styrene, so that the requirements of European Union plastic parts on safety and environmental protection are not met. Although a soft armor material and a preparation method thereof are provided in patent application No. CN201410334975.8 by Mr. Lidonghong of Huaying printing Limited company in Tianjin, the materials used by the soft armor material still contain ABS resin and SBS resin which have hazardous ingredients of styrene and plasticizer DOA resin powder which contains carcinogenic ingredients, the obtained product is unsafe and environment-friendly, meanwhile, the resin prepared by the method of blending the ABS into soft materials such as TPU, TPEE and the like is actually a modification of the ABS, the softness and elasticity of the resin are not too good, in addition, the preparation method of mixing the resins with different properties is not good for secondary processing, the problem of cracking and brittleness caused by mechanical fatigue is easy to occur, and the transparency of the product is not too high.

Therefore, the technical problem to be solved by the technical personnel in the field is to find an artificial nail material which is safe, environment-friendly, elastic, soft, high in transparency, comfortable and conformable to wear and convenient to process.

How to introduce a resin can be compatible with TPE and can provide good transparency. After tens of millions of formula tests and theoretical deductions of the inventor, the environment-friendly artificial nail material disclosed by the patent application is finally prepared.

The specific technical scheme of the invention is as follows:

Compared with polyethylene, the surlyn resin has very low crystallinity, good transparency and light transmittance of about 80-92 percent, and is ultrahigh transparent plastic. The special ionic crosslinking among the molecular chains of the sarin resin has reversibility. The cross-linking bond is dissociated when heated, and the product can melt and flow, and the cross-linking bond is recovered when cooled to room temperature.
