Anti-bacterial and heat-resistant rubber seal ring for instruments and apparatus

Abstract

The invention discloses an anti-bacterial and heat-resistant rubber seal ring for instruments and apparatus. The rubber seal ring comprises raw materials in parts by weight as follows: 20-40 parts of brominated butyl rubber, 5-15 parts of bifluoride rubber, 5-15 parts of fluororubber, 1-2 parts of zinc oxide, 0.5-1 part of magnesium oxide, 0.5-1 part of fatty acid, 1 part of sulfur, 5-15 parts of modified diatomite, 5-15 parts of white carbon black, 2-8 parts of fly ash, 1-4 parts of carbon nano tubes, 2-5 parts of bentonite, 1-3 parts of a silane coupling agent KH-540, 0.2-0.6 parts of chlorinated paraffin, 1-2 parts of chloro-methoxy methyl oleate, 0.2-0.6 parts of butyl oleate, 1-2 parts of dioctyl phthalate, 0.1-0.5 parts of diethylene glycol dibenzoate, 1-2 parts of a calcium-zinc composite stabilizer, 1-2 parts of an anti-aging agent H and 1-2 parts of phosphite ester. The rubber seal ring is good in anti-bacterial effect, excellent in mechanical performance, good in toughness and quite good in aging resistance and heat resistance.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a rubber sealing ring for antibacterial and heat-resistant instruments and meters. Background technique [0002] In recent decades, rubber materials and their products have developed vigorously. They are rapidly replacing natural polymers such as steel, metal, cement, wood, and cotton, and are widely used in various sectors of the national economy such as industry, agriculture, and military. Rubber materials are widely used in the industry to make sealing components. The instrument industry puts forward higher requirements for rubber materials. Traditional rubber materials cannot meet the needs due to poor antibacterial properties, heat resistance and aging resistance during long-term storage and use. Long-term use gradually appears. The phenomenon of becoming soft and sticky, hard and brittle or cracking makes its physical and mechanical properties deteriorate or even lose...
