Abstract

The invention discloses functionalized graphene-based solar back aluminum slurry and a preparation method thereof. The solar back aluminum slurry is prepared from the following raw materials in percentage by weight: 65-73 percent of aluminum powder, 1-3 percent of glass powder, functionalized graphene dispersion liquid containing 0.12-0.15 percent of functionalized pure graphene, 20-30 percent of organic carrier, 3-5 percent of auxiliary agent and the balance of diluent, wherein oxidized graphene is modified by using a coupling agent; the modified oxidized graphene is obtained through reaction of the coupling agent and the oxidized graphene and then is reduced to obtain the functionalized graphene; the functionalized graphene is dispersed into terpineol and butyl carbitol with a mass ratio of 5.5-6.5:1 after being subjected to ultrasonic treatment to form the functionalized graphene dispersion liquid. The preparation method comprises the steps of mixing, grinding and vacuum deformation of the raw materials. The solar back aluminum slurry has the advantages of high printing rate and good adhesion, conductivity, bending resistance and weathering resistance.

Description
