Embodiment 1

[0019] First, mix the thermosetting phenolic resin, curing agent, and latent curing agent according to the weight ratio of 1:0.05:0.20, then add it to a high-speed crusher and crush it into a 100-mesh fine powder, wherein the curing agent is urotropine, and the latent curing agent is bisphenol A phenolic resin; then, chlorinated polyethylene and ammonium hydrogen phosphate are added into the high-speed mixer together with the fine powder as a slow curing agent and mixed, and after mixing evenly, the material automatically enters the twin-screw extruder for extrusion and granulation. The diameter of the die head of the screw extruder is 2mm, the internal temperature is 120°C, and the back pressure is 4MPa, and high-speed cold air is introduced to cool the pellets to prevent the pellets from sticking when the extrusion die is cut and granulated; The conveying pipeline connected to the outlet of the twin-screw extruder transports the pellets in a cold air environment, and collects...

Embodiment 2

[0021] First, mix the thermosetting phenolic resin, curing agent, and latent curing agent according to the weight ratio of 1:0.10:0.15, then add it to a high-speed crusher and crush it into a 200-mesh fine powder. Oxygen resin; then add phenol as slow curing agent and fine powder together to the high-speed mixer for mixing, and after mixing evenly, the material will automatically enter the twin-screw extruder for extrusion and granulation. The die head aperture of the twin-screw extruder 5㎜, internal temperature 250°C, back pressure 12 MPa, and high-speed cold air is passed through the extrusion die to cool the pellets to prevent pellets from sticking; it is connected to the outlet of the twin-screw extruder Through the conveying pipeline, the pellets are transported in a cold air environment, and the pellets of thermosetting phenolic resin for energy storage electric carbon are collected. The granulation process of the present invention can make the raw materials of electric ...

Embodiment 3

[0023] First, mix the thermosetting phenolic resin, curing agent, and latent curing agent according to the weight ratio of 1:0.08:0.12, then add it to a high-speed crusher and crush it into a 225-mesh fine powder, wherein the curing agent is urotropine, and the latent curing agent is bisphenol A phenolic resin; then add ammonium hydrogen phosphate, phenol and p-toluenesulfonic acid as slow curing agent together with fine powder into the high-speed mixer and mix, after mixing evenly, the material will automatically enter the twin-screw extruder for extrusion and granulation The diameter of the die head of the twin-screw extruder is 3 mm, the internal temperature is 150 ° C, and the back pressure is 7 MPa. When the extrusion die is cut and granulated, high-speed cold air is introduced to cool the pellets to prevent the pellets from sticking. The conveying pipeline connected with the outlet of the twin-screw extruder transports the pellets in a cold air environment, and collects t...

Abstract

The invention discloses an granulating process of thermosetting phenolic resin for stored energy electrical carbon, and the granulating process comprises the following steps of: (1) mixing thermosetting phenolic resin, a curing agent and a latent curing agent, and then adding to a high-speed disintegrator to disintegrate into fine powder of 100-325 meshes; (2) adding the curing agent and the fine powder to a high-speed mixer, then mixing, discharging after the curing agent and the fine powder are uniformly mixed to automatically enter a double-screw extruder for extrusion and granulation, cutting and granulating on an extrusion mould head, and accessing high-speed cold air to cool granular materials so that the granular materials are prevented from being adhered at the same time; and (3) conveying the granular materials in a cold air environment by using a conveying pipeline communicated with the outlet of the double-screw extruder, and collecting to obtain the granular materials of the thermosetting phenolic resin for the stored energy electrical carbon. The electric carbon granular materials prepared through the granulating process disclosed by the invention are uniform in property and high in grain diameter consistency, can be used for enlarging the specific area of subsequently prepared carbon and ensuring the comprehensive property of the electric carbon, have the characteristics of high output, few procedure and low energy consumption, can be continuously produced and are suitable for popularization and usage.

Description

technical field [0001] The invention relates to the field of preparation of new carbon materials, in particular to a granulation process of a thermosetting phenolic resin for energy storage electric carbon with fewer procedures, high production capacity, less energy consumption and uniform performance of electric carbon particles. Background technique [0002] The thermosetting phenolic resin for energy storage electric carbon needs to be granulated before being made into electric carbon microspheres. The existing granulation process is simply mixed by crushing, so that the raw materials cannot be mixed uniformly and the obtained pellets It is easy to bond together, there are many processes and low production capacity, and the performance of the prepared electric carbon material is not uniform, which affects the use. Contents of the invention [0003] The object of the present invention is to aim at the defects of the prior art, and provide a granulation process of thermo...
