High-tenacity waterproof silicone rubber material

Abstract

The invention discloses a high-tenacity waterproof silicone rubber material which is prepared from the following raw materials in parts by weight: 20-60 parts of fluorinated silicone rubber, 20-40 parts of butyl rubber, 0.5-1.2 parts of a silane coupling agent KH550, 0.2-0.6 part of a coupling agent A-151, 20-40 parts of modified walnut shell fibers, 45-55 parts of barium metaborate, 2-8 parts of bentonite, 4-10 parts of bismuth oxide, 2-6 parts of boron oxide, 0.5-1.5 parts of dioctyl phthalate, 1-2 parts of trimethyl phosphate, 2-4 parts of di-tert-butyl peroxide, 0.2-0.6 part of ammonium dichromate potassium, 1-2 parts of titanium oxide acetylacetonate and 2-4 parts of an ultraviolet absorber UV-531. The high-tenacity waterproof silicone rubber material has excellent water resistance, tenacity and sealing property, excellent ageing resistance, good impact resistance and high hardness.

Description

technical field

[0001] The invention relates to the technical field of rubber, in particular to a high-toughness waterproof silicone rubber material. Background technique

[0002] Rubber, together with plastics and fibers, is called the three major synthetic materials, among which rubber is a polymer material with high elasticity and excellent elasticity. However, with the rise of the global low-carbon economy, green manufacturing has become one of the strategic guidelines for the sustainable development of my country's rubber industry. It is to increase industrial restructuring and vigorously develop safe, energy-saving, and environmentally friendly raw materials is the basis of green manufacturing. However, traditional rubber has poor toughness, and its waterproof performance cannot meet the demand. Contents of the invention

[0003] Based on the technical problems in the background technology, the present invention proposes a high-toughness waterproof silicone rubber m...
