Abstract

The invention relates to the technical field of filtering materials, discloses a graphene-based filtering material and a preparation method thereof, and aims to solve the problems that the filtering material prepared by the existing method is not good in flame retardant effect and cannot be suitable for a high-temperature environment on one hand, is poor in antioxidant effect on the other hand, and is easy to locally damage along with the increase of service life. The filtering material is prepared from components in parts by weight as follows: 2-8 parts of a graphene raw material, 10-20 parts of epoxy resin, 0.2-0.8 parts of a dispersing agent, 4-8 parts of a photocatalyst, 5-10 parts of a cold catalyst, 10-20 parts of hydrogen peroxide, 3-9 parts of silicate ester, 10-20 parts of a flame retardant, 5-10 parts of an antioxidant and 1.5-4.5 parts of an aid. According to the graphene-based filtering material, graphene and the flame retardant are combined and can generate a synergistic effect, the flame retardant capacity of the filtering material is effectively improved, meanwhile, a proper amount of antioxidant is added, the antioxidant effect of the filtering material can be remarkably improved, the filtering material is not prone to local damage along with the increase of the service life, and the service life of the filtering material is prolonged.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a graphene-based filter material and a preparation method thereof. Background technique [0002] The filter material can separate solid particles in liquid or gas, or make different material components fully contact, speed up the reaction time, and protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter screen or filter element with the filter material, its Impurities are blocked, while clean fluid flows out through the filter material, graphene is a sp 2 Graphene is a new material in which hybridized carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical, and mechanical properties. It is widely used in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It has important application prospects and is cons...
