Problems solved by technology

In addition, the preparation process of Shangshizhipain rubber ointment is complicated. For example, a large amount of organic solvent is used in the production process by solvent method, which brings unsafe factors to production and easily pollutes the environment.
If the hot pressing method is used in pulping and filtering, it is often difficult to filter due to improper storage of zinc oxide particles and absorb water, and it is difficult to clean mechanical equipment.
Therefore, plasters based on natural rubber are rarely seen in the international market at present due to complex processes, skin irritation, and serious allergies, and their application prospects are bleak.

Abstract

The present invention provides a making method of a damp pain-relieving rubber paste with good performance. On the basis of the recipe of an original damp pain-relieving paste, the damp pain-relieving rubber paste is made of special hot melt polymer adjuvant matrix, wherein the special hot melt polymer adjuvant matrix is made of a hot plastic elastic body, medical rubber, softeners, antioxidant and the like which are prepared according to certain proportion. The making process of the damp pain-relieving rubber paste with good performance is simple, organic menstruum is not needed, and the making method of a damp pain-relieving rubber paste with good performance is safe and environmental. The rubber covering speed is fast, and the production efficiency is high. The damp pain-relieving rubber paste made by the present invention has small stimulation for skins, and has no allergic phenomenon. The sticking is comfortable. The damp pain-relieving rubber paste can not pollute clothes, can not stick hair, can be stuck repeatedly, and is the upgrading change generation product of damp pain-relieving paste plaster.
