Abstract

The invention relates to an anti-corrosion medical rubber and a preparation method thereof, and belongs to the field of medical materials. The anti-corrosion medical rubber comprises the following components in parts by weight: 15-20 parts of butadiene styrene rubber, 5-15 parts of fluorinated silicone rubber, 2-5 parts of ethylene propylene diene monomer, 1-3 parts of angelica dahurica extract, 2-6 parts of potassium pyrrolidone carboxylate, 1-5 parts of polyamide wax micro-powder, 2-3 parts of triethanolamine, 1-3 parts of boron carbide and 2-10 parts of magnesium stearate. The medical rubber provided by the invention has excellent bending strength, tensile strength and corrosion resistance; the service life of the medical rubber can be effectively prolonged; the preparation method provided by the invention is simple and practicable, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a corrosion-resistant medical rubber and a preparation method thereof. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. Rubber not only provides daily and medical light industrial rubber products that are indispensable to people's daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products and its prospects are very broad. Rubber is divided into natural rubber and synthetic rubber according to raw materials; according to form, it is divided into block raw rubber, latex, liquid rubber and powdered rubber. Latex is a colloidal water dispersion of rubber; liquid rubber is an oligomer o...
