Problems solved by technology

However, graphene is only composed of carbon atoms and does not contain any functional groups. At the same time, graphene has poor solubility and compatibility with rubber due to the electrostatic effect of its sheets, so it cannot play the greatest role in rubber composite materials.

Abstract

The invention relates to the technical field of new materials, in particular to a graphene rubber polymer far infrared composite foam material, which comprises the following raw materials in parts by weight: 30-45 parts of natural rubber, 5-9 parts of POE (Polyolefin Elastomer), 10-12 parts of EPDM (Ethylene-Propylene-Diene Monomer), 8-14 parts of white carbon black, 3-6 parts of isoprene rubber, 2-5 parts of zinc stearate, 5-8 parts of graphene oxide, 6-9 parts of zinc oxide, 3-8 parts of an odorless cross-linking agent, 3-5 parts of stearic acid, 4-7 parts of a foaming agent and 5-8 parts of a silane coupling agent, wherein the graphene oxide is prepared by taking graphite, sodium nitrate, potassium permanganate and concentrated sulfuric acid as raw materials. The graphene oxide in the composite material disclosed by the invention is good in dispersity in the natural rubber, so that the far infrared light emissivity of the graphene can be better improved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a graphene rubber polymer far-infrared composite foaming material. Background technique [0002] Far infrared refers to the light outside the red light, which belongs to the category of electromagnetic waves and has a strong heating effect. Because far-infrared rays have such functions, they have special functions in medicine, such as being able to penetrate deep into the subcutaneous tissue of the human body to promote blood circulation. The deep penetration of far-infrared rays can reach the depths of muscle joints, improve joint pain, regulate autonomic nerves, and metabolize human fatigue and aging substances directly from the skin, and can also beautify and lose weight. Far-infrared rays are also an excellent Physiotherapy can promote blood circulation, improve circulatory system, enhance metabolism, and improve immune function. Tested by the National Far Infrared Ce...
