Graphene heat dissipation film production device

Abstract

The invention discloses a graphene heat dissipation film production device. According to the graphene heat dissipation film production device, the problem that existing equipment is low in dispersionefficiency is solved through a dispersion assembly; multi-stage dispersion is achieved through a first dispersion part and a second dispersion part, dispersion dead angles are reduced through an inclined main dispersion disc, an inclined auxiliary dispersion disc and an inclined transition dispersion disc, a plurality of dispersion areas are formed, and graphene is fully and preliminarily dispersed and separated in a solvent through mutual collision and friction of multiple main dispersion blocks, auxiliary dispersion blocks, transition dispersion blocks and graphene aggregate particles; and awobble plate mechanism is formed among a driving shaft A, a driving shaft B, a transmission shaft A, a transmission shaft B and a dispersion ring B, so that dispersion liquid is fully dispersed, thedispersion efficiency is guaranteed, and the dispersion time is shortened. A substrate is conveyed and preheated through an auxiliary assembly, it is guaranteed that the solvent is rapidly evaporatedwhen the dispersion liquid makes contact with the substrate, graphene agglomeration is avoided, and therefore a uniform film is obtained, and the problem that after existing graphene dispersion liquidis sprayed to the substrate, small liquid drops are formed, and agglomeration is caused is solved.

Problems solved by technology

Graphene heat dissipation film is usually prepared by spraying method, that is, a professional spray gun is used to spray graphene dispersion onto the substrate, but the existing spraying method for preparing graphene heat dissipation film has the following problems: first, graphene is very easy to agglomerate, Existing equipment has low dispersion efficiency and cannot fully disperse graphene to obtain a high-quality graphene dispersion; second, after the fully dispersed graphene dispersion is sprayed on the substrate, small droplets will form and cause agglomeration
