Abstract

The invention belongs to the technical field of high-molecular polymers, and particularly relates to special graphene mother liquor for thermosetting phenolic resin and a preparation method. Graphene is dispersed in a sodium polyphosphate aqueous solution and has affinity with acidification modified nanometer bentonite, graphene is loaded between lamellae and on lamella surfaces of nanometer bentonite, and on the basis of quite high binding performance of alkaline sodium polyphosphate and nanometer bentonite, graphene and bentonite are tightly complexed and loaded to form a graphene-bentonite complex. The dispersing performance of the complex is far better than that of graphene, and furthermore, the graphene-bentonite complex and phenol form the graphene mother liquor with stable dispersing performance under the assistance of a solvent and a surfactant. The method is simple and easy, the technological process is short, the production process is pollution-free, the cost is low, and the method is suitable for industrial production. The obtained graphene mother liquor is convenient to use and well-adapted, and one advanced and efficient way is provided for large-scale application of graphene in thermosetting phenolic resin.

Description

technical field [0001] The invention belongs to the technical field of graphene application, and in particular relates to a special graphene mother liquor for thermosetting phenolic resin and a preparation method thereof. Background technique [0002] Phenolic resins are often formed by polycondensation of phenolic compounds and aldehyde compounds. Because the phenolic molecule has a rigid benzene ring structure, the phenolic resin has stable dimensions, stable chemical composition, good rigidity, small deformation, heat resistance and wear resistance, and can be used for a long time in the temperature range of 150~200 °C. It is used in the manufacture of gears, bearing bushes, guide wheels, silent gears, bearings, electrical structural materials and electrical insulation materials. It has excellent electrical insulation properties, heat resistance, water resistance, and wear resistance. It can make various coil holders, wiring boards, electric tool casings, fan blades, aci...
