Problems solved by technology

However, when shaving, the skin is easily scratched by the sharp blade. It is necessary to apply lubricating fluid or soap bubbles to prevent the razor from damaging the skin and reduce the running resistance of the razor. After shaving, apply skin cream to protect the skin. The operation steps of the shaving process are complicated and time-consuming

Embodiment approach 1

[0071] Embodiment 1, a lubricating strip for a razor, at least composed of an elastomer and a polyrotaxane, the polyrotaxane consists of 100 parts by weight of a linear polymer, 200-500 parts by weight of a cyclic molecule and 1-15 parts by weight prepared from endcapped macromolecules in parts by weight, the cyclic molecule is cyclodextrin, the linear polymer is one or more of PEG, PPG, PCL, PVA, PMMA, PEI and PB, the The capped macromolecule is capped at both ends of the linear polymer, and the mass ratio of the elastomer to the polyrotaxane is 1:0.1-1.

Embodiment approach 2

[0072] Embodiment 2 is the same as Embodiment 1, except that the elastomer is one or more of SEBS, SBS, TPEE and EVA.

Embodiment approach 3

[0073] Embodiment 3 is the same as Embodiment 1, the difference is that the end-capped macromolecules are amantadine, cyclodextrin aldehyde, triphenyl derivatives, fluorescamine and fluorescein isocyanate, poly-terminated methyl polyethylene glycol One of alcohol methacrylate and hydroxyethyl methacrylate.

Abstract

The invention relates to a lubricating strip for a shaver. The lubricating strip is at least composed of an elastomer and polyrotaxane. The polyrotaxane is prepared with, by weight, 100 parts of a linear polymer, 200-500 parts of cyclic molecule and 1-15 parts of capped macromolecule. The cyclic molecule is cyclodextrin. The linear polymer is one or more selected from PEG, PPG, PCL, PVA, PMMA, PA and PB. The capped macromolecule is capped on the two ends of the linear polymer. A mass ratio of the elastomer to polyrotaxane is 1:0.1-1. The lubricating strip also comprises a moisturizing agent which is one or more selected from olive oil, jojoba oil and glycerin. According to the invention, the elastomer and polyrotaxane are mixed; the mixture is heated and is subjected to a melting reaction under a temperature of 100-250 DEG C; the temperature is reduced to 90-110 DEG C, and the moisturizing agent is added; the mixture is mixed and stirred, and is subjected to granulation and shaping, such that the lubricating strip is obtained. The preparation method is simple. The lubricating strip has the advantage of good friction lubricating performance. The lubricating strip can be used multiple times, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of razors, and more specifically, the invention relates to a lubricating strip for razors. Background technique [0002] Regular razors are cheap compared to electric shavers. However, when shaving, the skin is easily scratched by the sharp blade. It is necessary to apply lubricating fluid or soap bubbles to prevent the razor from damaging the skin and reduce the running resistance of the razor. After shaving, apply skin cream to protect the skin. The operation steps of the shaving process are complicated and time-consuming. [0003] In order to overcome the shortcomings of ordinary razors, a lubricating strip is proposed to play a lubricating role during shaving, and the lubricating strip can be recycled to prolong the service life of the lubricating strip and make the skin feel moist and painless. Contents of the invention [0004] In order to solve the above problems, the present invention provides a lubric...
