Abstract

The invention discloses a nanometer zinc oxide modified natural rubber sealing gasket, and relates to the technical field of natural rubber processing. The nanometer zinc oxide modified natural rubber sealing gasket is prepared from the following raw materials in parts by mass: 100 to 110 parts of natural rubber, 10 to 15 parts of nanometer zinc oxide, 8 to 10 parts of magnesium carbonate, 4 to 8 parts of diphenyl silandiol , 3 to 5 parts of trioctyl trimellate, 4 to 7 parts of coumarone-indene resin, 2 to 5 parts of rosin, 3 to 8 parts of decabromodiphenyl ethane, 1 to 4 parts of sodium stearate, 4 to 9 parts of ethyl carbamate, 1 to 4 parts of propolis, 3 to 6 parts of N-cyclohexylthiophthalimide, 1.5 to 3 parts of maleic anhydride, 2 to 5 parts of an antioxidant and 3 to 7 parts of kaolin. According to the nanometer zinc oxide modified natural rubber sealing gasket, nanometer zinc oxide is used for modifying natural rubber, and the modified natural rubber sealing gasket is prepared under the synergistic effects of the other components, and is high in high temperature resistance, sealing performance, flame resistance and wear resistance and long in service life.

Description

Technical field: [0001] The invention relates to the technical field of natural rubber processing, in particular to a nano zinc oxide modified natural rubber sealing gasket. Background technique: [0002] Natural rubber is a renewable polymer material with superior comprehensive properties, featuring high elasticity, high strength and wear resistance. It is widely used in aerospace, national defense and military industry, tires, and medical elastomers, and occupies a very large role in the national economy. Important position. Due to its small particle size, large specific surface area and strong adsorption activity, nano-zinc oxide has surface effect and high activity. Nano-sized zinc oxide can be combined with rubber molecules to achieve the purpose of improving the performance of the rubber compound, and at the same time reduce the amount of zinc oxide, which is in line with the current trend of environmental protection development. [0003] Gasket is a material used fo...
