Silicone rubber synthetic leather for medical device and preparation method thereof

Abstract

The invention discloses silicone rubber synthetic leather for a medical device. The silicone rubber synthetic leather comprises a cloth base orderly coated with a silicone rubber layer for a medical device and a surface layer for the medical device. The surface layer for the furniture in the hospital and the nursing institution comprises, by mass, 30-50 parts of high viscosity vinyl silicone oil,10-20 parts of vinyl MQ resin, 10-20 parts of vinyl phenyl silicone resin, 3-10 parts of high hydrogen content silicone oil, 10-20 parts of silicon micropowder, 0.05-0.1 part of a platinum catalyst and 0.01-0.03 parts of a retardation agent. The silicone rubber synthetic leather has excellent high and low temperature resistance, weather resistance and hydrolysis resistance, excellent skin-friendlyproperties, no cytotoxicity, no sensitization and no irritation or intradermal reaction. A preparation method of the silicone rubber synthetic leather has simple processes, high production efficiencyand low cost.

Description

technical field [0001] The invention relates to silicone rubber synthetic leather, in particular to a silicone rubber synthetic leather used in medical equipment, and a manufacturing technology of the silicone rubber synthetic leather used in medical equipment. Background technique [0002] Synthetic leather is widely used in modern life, and is widely used in various fields such as clothing, gloves, bags, furniture, and shoe uppers. [0003] Part of the outer packaging of medical devices also needs to use synthetic leather, but synthetic leather is easily hydrolyzed and corroded in a humid environment, and it cannot be cleaned by washing, which leads to the problem that synthetic leather cannot be cleaned quickly and conveniently during use , which greatly restricts the use of synthetic leather in medical devices. [0004] At the same time, the weather in southern my country is hot and the air humidity is high. Synthetic leather products are prone to mildew, and mildew may...

AI Technical Summary

Problems solved by technology

[0003] Part of the outer packaging of medical devices also needs to use synthetic leather, but synthetic leather is easily hydrolyzed and corroded in a humid environment, and it cannot be cleaned by washing, which leads to the problem that synthetic leather cannot be cleaned quickly and conveniently during use , which greatly restricts the use of synthetic leather in medical devices

[0004] At the same time, the weather in southern my country is hot and the air humidity is high. Synthetic leather products are prone to mildew, and there is also the possibility of mildew in the north.

Mild mold stains on the surface of synthetic leather can be wiped off, which only affects the appearance of synthetic leather and makes the grain surface of synthetic leather lose luster; however, severe mildew stains may make the grain surface of synthetic leather mildewy and brittle

Aihor anti-mildew research analysis: the most effective and main way to prevent synthetic leather is to add anti-fungal agents, but anti-fungal agents generally have different degrees of impact and harm on humans, animals, the environment, etc., and most products are expensive

[0005] In addition, medical devices are easily contaminated by germs during storage. The use of conventional synthetic leather is easy to breed germs and cause cross-infection, and it is prone to wear and tear due to frequent use.
