For example, adding mineral powder often reduces the strength while toughening; glass fiber reinforcement usually reduces the toughness; and adding graft copolymerized elastomers to toughen often sacrifices the valuable rigidity, dimensional stability, and heat resistance of the material. For the price, so it is necessary to find a modifier to improve the overall performance of MC nylon

Abstract
The invention discloses a preparation method of a tear-resistant modified composite environment-friendly rubber base material. The method comprises the following steps: preparing graphene oxide with high oxidation degree; and modifying the graphene oxide to prepare the tear-resistant modified composite environment-friendly rubber base material. In the invention, by adopting asphalt-based carbon fiber, the mechanical property of the material is enhanced, the harmful gases and dust matters in tail gas can be greatly adsorbed and eliminated, and the obtained MC nylon has good overall performance. By cooperatively adopting the main materials including epichlorohydrin rubber, nitrile butadiene rubber, acrylonitrile-butadiene copolymer rubber, diene rubber, styrene butadiene rubber and regenerated rubber, the toughness of the material is greatly improved, and the condition that a conveyer belt is easily broken is effectively solved; meanwhile, gases harmful to a human body are not generated at relatively high temperature; and through perfect fusion of the high-temperature resistance, tear resistance and the like, the tear-resistant modified composite environment-friendly rubber base material provided by the invention can be applied to various severe conditions. The added components not only effectively ensure that the protected material is not burnt easily, and but also avoid the generation of gases harmful to the human body when being burnt at extremely high temperature; and compared with the hydrotalcite currently applied on the market, the tear-resistant modified composite environment-friendly rubber base material has obvious advantages of high-temperature resistance, fireproof property and flame retardance.
Description
technical field [0001] The invention relates to a preparation method of a tear-resistant modified composite environment-friendly rubber base material, in particular to a preparation method of MC nylon / modified graphene oxide nanocomposite material. Background technique [0002] Cast nylon (MC nylon) is one of the most widely used engineering plastics. It has the advantages of low cost, high output, high reaction rate and good mechanical properties. It is widely used in the preparation of bearings, gears, pulleys, etc., especially To prepare some large devices that cannot be prepared by compression molding or extrusion molding, MC nylon has gradually replaced some metal materials, such as copper, aluminum, steel and iron, in many fields. However, compared with metal materials, MC nylon still has shortcomings such as high elastic modulus, poor low-temperature toughness, low impact strength, and poor dimensional stability, which limit the application of MC nylon to a certain ex...
