Abstract

A preparing method of an oil-proof modified composite environment-friendly rubber base material is disclosed. The method includes preparing graphene oxide having a high oxidation degree, modifying the graphene oxide and preparing the oil-proof modified composite environment-friendly rubber base material. The base material adopts pitch-based carbon fibers to enhance mechanical properties, and can greatly adsorb and clean harmful gas and dust compounds in tail gas. Prepared MC nylon has an advantage of good comprehensive properties. The base material can be used for works under various bad conditions. Added components can effectively ensure no easy combustion of a protected material, and do not generate gas harmful to human bodies during combustion at overhigh temperatures. Compared with hydrotalcite in the market at present, the base material has obvious advantages in the fields of high-temperature resistance, fire protection and flame retardance.

Description

technical field [0001] The invention relates to a preparation method of an oil-resistant modified composite environment-friendly rubber substrate, in particular to a preparation method of an 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 ext...
