Embodiment 1

[0039] (1) Add 1 gram of graphene oxide, 5 grams of hydrazine hydrate, 5 grams of sodium dodecylbenzenesulfonate, and 260 grams of formaldehyde solution with a concentration of 44% into a four-necked bottle, start stirring, and slowly heat up to 100 ° C The next reaction is 6 hours;

[0040] (2) When the reaction solution is cooled to 75°C, add acid to adjust the pH to 2.3, then add 600 g of phenol, and react at 95°C for 2 hours. After the reaction, the reaction mixture is heated and dehydrated to a temperature of 160°C to obtain thermoplastic graphene Phenolic Resin.

Embodiment 2

[0042] Compared with Example 1, the difference is that 5 grams of graphene oxide, 25 grams of hydrazine hydrate and 20 grams of sodium dodecylbenzene sulfonate are added.

Embodiment 3

[0044] Compared with Example 2, the difference is that 15 grams of hydrazine hydrate is added,

Abstract

The invention relates to the technical field of phenolic resin composite materials, in particular to a graphene phenolic resin composite material. Oxidized graphene, hydrazine hydrate, a surfactant and a formaldehyde solution are added into a reactor, stirred and heated up to 80-100 DEG C for reaction; the obtained liquid reactant is cooled down to 60-80 DEG C, then an acid catalyst and phenol are added, the temperature is increased to 85-100 DEG C for reaction, and then heating dehydration is performed. The graphene phenolic resin composite material can be applied to bakelite powder. As the proper surfactant is adopted, the problem of dispersion of graphene in resin is solved, and uniformly mixed graphene modified phenolic resin is obtained; the oxidized graphene which is not reduced can further react with phenolic resin to obtain graphene modified phenolic resin of an inorganic complexing structure; the bakelite powder prepared by resin has relatively high impact resistance and low forming shrinkage ratio.

Description

technical field [0001] The invention relates to the technical field of phenolic resin composite materials, in particular to a graphene phenolic resin composite material, a preparation method of the graphene phenolic resin composite material, and an application of the graphene phenolic resin composite material. Background technique [0002] Phenolic resin is the earliest industrialized synthetic resin in the world. It has a history of nearly a hundred years. Due to its easy-to-obtain raw materials, low price, simple production process and equipment, and more importantly, its excellent mechanical properties, heat resistance, and Ablation performance, electrical insulation performance, formability and flame retardancy have become indispensable materials in the bakelite industry. The traditional unmodified phenolic resin has high brittleness, poor toughness and shrinkage during molding, which limit its application in high-end bakelite products.
