Solid powder antistatic agent and preparation method thereof

Abstract

The invention discloses a solid powder antistatic agent and a preparation method thereof, and belongs to the technical field of powder antistatic assistants, the solid powder antistatic agent comprises the following raw materials: paint slag, conductive carbon black and graphene according to a mass ratio of (25-50): (25: 50): (1-2). The used graphene is few-layer graphene and/or multi-layer graphene with the carbon content not lower than 95%, and the paint slag is waste slag generated in the paint spraying process or residues of waste paint. The preparation method of the antistatic agent comprises the following steps: removing impurities from paint slag, and performing high-temperature pretreatment; then mixing with conductive carbon black and graphene at a high speed, and carrying out ball milling for 2-4 hours; and finally, sieving with a 600-mesh sieve. By adopting the technology provided by the invention, the paint slag is used for replacing conductive carbon black in a large proportion, so that the problem of environmental pollution caused by carbon black production is effectively reduced, and the problem of paint slag recycling is solved; the antistatic agent with a good antistatic effect is prepared.

Description

technical field [0001] The invention belongs to the technical field of powder antistatic additives, in particular to a solid powder antistatic agent and a preparation method thereof. Background technique [0002] Static electricity is one of the main "killers" that seriously threaten various industries, and the awareness of static electricity prevention is also getting more and more attention. In the process of material conveying, static electricity is easily generated due to the friction between the conveyor belt and the conveyed items during operation. When this static electricity accumulates to a certain extent, it will lead to serious consequences such as fire. Therefore, the conveyor belt is generally required to have an antistatic function. Common antistatic conveyor belts are generally antistatic by adding conductive carbon black to the formula. [0003] At present, in order to save resources, more and more attention is paid to waste recycling. With the rapid deve...
