Abstract

The invention discloses a graphene cold-resistant rubber polymer composition. The graphene cold-resistant rubber polymer composition prepared from the following raw materials in parts by weight: 60-68parts of natural rubber, 8-12 parts of polybutadiene rubber, 23-29 parts of low-pressure polyethylene, 13-17 parts of polyphenylene ether, 4-6 parts of oxidized polyethylene, 3-4.5 parts of a flow additive, 2.6-3.4 parts of grapheme, 5-8 parts of silane coupling agent modified white carbon black, 3-5 parts of fumed silica, 2-3 parts of a foaming agent, 1.4-1.8 parts of activated zinc oxide, 1.6-1.9 parts of a bridging agent, 1.5-2.2 parts of a cross-linking agent, 3-5 parts of an antioxidant and 3-5 parts of a heat stabilizer. The graphene cold-resistant rubber polymer composition is low in compression permanent deformation rate, good in resilience, high in tensile strength, high in elongation at break, excellent in shear performance, good in comprehensive performance, excellent in processing performance, good in apparent quality, most importantly, low in brittleness temperature and good in low temperature resistance, can be used in a long term in the range of normal temperature to -40 DEG C, and is excellent in cold resistance.

Description

technical field

[0001] The invention relates to the technical field of rubber products, in particular to a graphene cold-resistant rubber polymer composition and a preparation method thereof. Background technique

[0002] Natural rubber (NR) is a natural polymer compound with cis-1,4-polyisoprene as the main component, and 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene Diene), and the rest are non-rubber substances such as protein, fatty acid, ash, sugar, etc. It is generally flake solid, relative density 0.94, refractive index 1.522, elastic modulus 2-4MPa, softens at 130-140°C, sticky and soft at 150-160°C, and begins to degrade at 200°C. It has high elasticity at room temperature, slightly plastic, and crystallizes and hardens at low temperature. It has good alkali resistance, but not strong acid resistance. Insoluble in water, lower ketones and alcohols, can swell in non-polar solvents such as chloroform, carbon tetrachloride, etc. [0003...
