Problems solved by technology

However, the existing ultraviolet light grafting method has weak penetrating power to the material, the grafting effect is not ideal, and it is prone to uneven grafting, and the surface structure is unstable, causing the hydrophilic lubricating coating to fall off easily. Maintain long-term hydrophilic lubricity, which is not conducive to long-term use

Abstract

The invention belongs to the technical field of massaging equipment, and particularly relates to a massaging unit and a preparation method and application thereof. The massaging unit provided by the invention is mainly prepared from a substrate material, wherein the surface of the substrate material is provided with a hydrophilic lubricating coating; the substrate material is mainly prepared from a silicon rubber component A and a silicon rubber component B in a mass ratio of 1 to (0.5-2). The preparing method of the massaging unit disclosed by the invention comprises the following steps: uniformly mixing the silicon rubber component A and the silicon rubber component B according to a certain proportion, and curing to obtain a substrate material; preparing a hydrophilic lubricating coating on the surface of the substrate material in an ultraviolet photografting way; injecting the substrate material of which the surface is coated with the hydrophilic lubricating coating into a mold of the massaging unit, heating and molding to obtain the massaging unit. The massaging unit disclosed by the invention has higher mechanical performance, high hydrophilic lubricating performance, high stability and long service life.

Description

technical field [0001] The invention belongs to the technical field of massage equipment, and in particular relates to a massage unit and its preparation method and application. Background technique [0002] Silicone rubber is a highly active adsorption material, which is an amorphous substance, non-toxic, tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. It has a wide range of applications in all walks of life and in daily life. application. What is particularly prominent is that silicone rubber is widely used in medical fields due to its stable physical and chemical properties, good biocompatibility, tissue compatibility and anticoagulant properties, such as massage equipment, artificial ears, tracheal intubation, catheter Medical silicone rubber has become one of the most widely used and most valuable medical polymer materials. Especially in recent years, the application of silicone rubber in mass...
