Abstract
(EN)
The present invention relates to a medical silicone rubber with high mechanical properties and a preparation method thereof, the medical silicone rubber comprises the following raw materials in parts by weight: 50-90 parts of silicone rubber, 10-50 parts of polyurethane, 10-50 parts of filler, 2-6 parts of hydrogen-containing silicone oil and 2-5 parts of vulcanizing agent. The preparation method comprises: uniformly banbury compounding a part of the filler and silicone rubber in an internal mixer for use, and uniformly banbury compounding the remaining filler and polyurethane in the internal mixer for use; mixing the banbury compounded polyurethane on an open rubber mixer, then sequentially adding, in a small amount for many times, hydrogen-containing silicone oil, uniformly banbury compounded silicon rubber and vulcanizing agent to the open rubber mixer, and finally vulcanizing the mixed rubber on a flat rubber vulcanizing machine for 5-15 min at the temperature of 150-190℃ to obtain the medical silicone rubber with high mechanical properties. The medical silicone rubber with high mechanical properties has the characteristics of good mechanical properties, no irritation, high safety and the like.
