Silicone rubber composition and preparation method thereof

Abstract

The invention discloses a silicone rubber composition. The silicone rubber composition is prepared from the following components in parts by weight: 100 parts of methyl vinyl silicone rubber; 25 to 60 parts of reinforcement filler; 100 to 400 parts of X-ray absorbent; 2 to 20 parts of processing agent; and 0.2 to 3 parts of cross-linking agent. The silicone rubber composition adopts the methyl vinyl silicone rubber as a base material to be combined with the reinforcement filler, the X-ray absorbent, the processing agent and the cross-linking agent to generate the silicone rubber composition, after being cured, the silicone rubber composition has good shielding and protective effect for X-rays, also has good weather resistance, mechanical strength and toughness, is conveniently made into various types of protective products and is suitable for being popularized to use.

Description

technical field

[0001] The invention relates to a silicone rubber composition, in particular to a silicone rubber composition and a preparation method thereof. Background technique

[0002] X-ray is an indispensable technical means in modern medical imaging examination, especially in interventional radiology procedures such as cardiovascular angiography and angioplasty and fine surgery. Obtain imaging data in patients in trauma situations.

[0003] When X-rays irradiate the human body, they will interact with the body's cells, tissues, body fluids, etc., directly destroy some macromolecular structures in the body, and even directly damage the cell structure. In addition, X-rays can ionize water molecules in the body to form some free radicals, and damage the body through the indirect action of these free radicals. For patients, it is relatively safe and harmless to be exposed to X-ray radiation for a short time during treatment; but for medical staff, they need to be expos...
