Preparation method of high-resilience rubber material and hemorrhoid ligation rubber gasket

Abstract

The invention discloses a preparation method of a high-resilience rubber material, which comprises the steps of banburying, kneading, tableting, and vulcanization; the banburying time is 4-8 minutes, and the banburying temperature is 72-88°C; the kneading time is 16-24 minutes , the refining temperature is 35-55°C; the vulcanization time is 250-300s, and the vulcanization temperature is 140-160°C; the raw material composition of the high-resilience rubber material includes: 100 parts of natural rubber, 1.2-2.5 parts of stearic acid, and 2.5 parts of accelerator ~4 parts, anti-aging agent 0.3~1.5 parts, vulcanizing agent 5.3~8 parts. The present invention removes the white carbon black component in the apron material in the prior art, and uses an improved combination of vulcanizing agent and accelerator to enhance the resilience and strength of the mixed rubber, and the apron made of the above material is permanently deformed Small, the hemorrhoids can be tightened instantly during the ligation process, not easy to fall off, and can effectively block the blood flow of hemorrhoids.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a preparation method of a high-resilience rubber material and an apron for hemorrhoid ligation. Background technique [0002] One of the measures currently used to treat external hemorrhoids is to use hemorrhoid rubber rings to bind the hemorrhoids to block the blood supply of the hemorrhoids, so that the hemorrhoids are gradually ischemic, necrotic and fall off, so as to achieve the therapeutic purpose of controlling hemorrhoids bleeding and reducing prolapse. The ligation rubber ring usually needs to be used with a ligation device, and the ligation ring needs to be stretched on the ligation device, and the pushing mechanism of the ligation device will instantly shrink the rubber ring to the ligation part of the hemorrhoid. The above process determines that the apron used for hemorrhoid ligation must have high elongation and instant rebound performance, and the increase in the in...

Problems solved by technology

Specifically, white carbon black not only has the tendency to adsorb the compounding agent in the vulcanization system, which leads to the delay of vulcanization, but also causes the problem of hardening of the mixed rubber, which is generally called "structural effect". increase, even to the point that it cannot be re-smelted or scrapped

Simply removing the silica in the raw material components will significantly reduce the hardness, but it is not conducive to ensuring the tear resistance and tensile strength of the vulcanized rubber
