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

preparation example Construction

[0079] In an optional embodiment, the preparation method of the hydrophilic lubricating coating includes the following steps:

[0080] (a) Soak the autoclaved matrix material in an acetone solution containing photosensitizer for pretreatment;

[0081] (b) Put the pretreated matrix material into a reactor containing a mixed solution of OP-10 and PEG1000. The reactor is airtight and nitrogen gas is introduced. The graft is irradiated with ultraviolet light for 25min~55min. Form a grafted modified layer;

[0082] (c) Remove the residues of the base material with the grafted modified layer attached to the surface;

[0083] (d) Under the protection of nitrogen, immerse the material obtained in step (c) in a solvent containing a hydrophilic monomer and an initiator, and irradiate it under ultraviolet light for 1 to 8 minutes;

[0084] (e) Immerse the material obtained in step (d) in a solvent containing a crosslinking agent and additives, and perform irradiation crosslinking under ultraviole...

Embodiment 1

[0104] A massage unit, which is mainly prepared from a base material, and the base material is mainly prepared by mixing silicone rubber A component and silicone rubber B component with a mass ratio of 1:1;

[0105] The surface of the base material has a hydrophilic lubricating coating. The hydrophilic lubricating coating includes a grafted modified layer and a hydrophilic lubricating layer. The grafted modified layer is provided on the outer surface of the base material, and the hydrophilic lubricating layer is provided on the grafted surface. The outer surface of the modified layer; the grafted modified layer and the hydrophilic lubricating layer form an interpenetrating cross-linked network.

[0106] Among them, the silicone rubber component A is mainly prepared from the following mass parts of raw materials:

[0107] 100 parts of methyl vinyl polydimethylsiloxane, 25 parts of white carbon black, 20 parts of magnesium oxide and 0.5 part of olefin complex of chloroplatinic acid;

[...

Embodiment 2

[0111] A massage unit. The difference from Embodiment 1 is that the base material is mainly prepared by mixing silicone rubber A component and silicone rubber B component with a mass ratio of 1:2, and the rest are the same as Embodiment 1.

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 particularly relates to a massage unit and a preparation method and application thereof. Background technique [0002] Silicone rubber is a kind of highly active adsorption material. It is an amorphous substance, non-toxic, odorless, stable in chemical properties, and does not react with any substances except strong alkalis and hydrofluoric acid. It is widely used in various industries and daily life. application. What’s more prominent is that silicone rubber is widely used in the medical field because of its stable physical and chemical properties, good biocompatibility, tissue compatibility and anticoagulant properties, such as massage equipment, artificial ears, tracheal intubation, and catheters. Medical silicone rubber has become one of the most widely used and most valuable medical polymer materials for urinary catheters, ventricular and abdominal drainage tubes. Especially in re...
