Description

technical field [0001] The invention relates to the technical field of medical materials, in particular 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 necessities, medical and other light industrial rubber products that are indispensable to people's daily life, but also provides various rubber production equipment or rubber parts to heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. 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 powder rubber. Latex is a colloidal water dispersion of rubber; liquid rubber is an oligomer of rubb...
