Problems solved by technology

However, the application of self-lubricating fabric gasket materials based on phenolic resin under the irradiation of high-energy rays has not been reported so far.
Attributed to the reason, on the one hand, considering the weak radiation resistance of phenolic resin itself; on the other hand, no suitable solid lubricant has been found

Abstract

The present invention provides a high-energy-irradiation-resistant self-lubricating fabric liner, a preparation method and a self-lubricating fabric composite material, and relates to the technical field of functional materials. By taking g-C3N4 and multi-layer graphene as a composite solid lubricant, the requirements of the self-lubricating fabric liner on low friction and abrasion resistance aremet. Meanwhile, the unique six-membered ring structure of the g-C3N4 and multi-layer graphene endows the self-lubricating fabric liner with the certain irradiation resistance, thereby prolonging theservice life of the self-lubricating fabric liner. In addition, by flexible conversion of chemical valence of cerium in cerium dioxide, the irradiation resistance of matrix resin (phenolic resin) is effectively improved. Moreover, the preparation method of the self-lubricating fabric liner is simple, environment-friendly and pollution-free. Furthermore, the self-lubricating fabric composite material formed by the high-energy-irradiation-resistant self-lubricating fabric liner has excellent high energy irradiation resistance and tribology performance.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a high-energy radiation-resistant self-lubricating fabric liner, a preparation method, and a self-lubricating fabric composite material. Background technique [0002] Self-lubricating fabric liners are widely used in the design and manufacture of self-lubricating spherical plain bearings due to their own lubricating properties, relatively light weight and easy processing. In the fields of medicine, aerospace, nuclear industry, and weapon systems, self-lubricating materials will inevitably be exposed to high-energy radiation (such as electron beam irradiation, X-ray irradiation, and γ-ray irradiation, etc.), Among them, the γ-ray irradiation with strong penetrating ability is even more fatal to the material damage. Polymer materials exposed to γ-ray irradiation for a long time will generate free radicals after their molecular chains absorb ionization energy, which wi...
