Flat agent 1-3 parts, 1-5 parts of wetting agent, 10-20 parts of pigment.
Preferably, the raw material of the powdery paints includes: that 50 parts of E-12 type epoxy resin, graphene change according to parts by weight
Property 3 parts of phenolic resin curing agent, 20.4 parts of barium sulfate, 8 parts of mica powder, degassing 1 part of wax, 1 part of levelling agent, 1.6 parts of wetting agent,
15 parts of pigment.
The preparation method of the modified phenolic resin curing agent of the graphene: by bodies such as 30wt% hydrogen peroxide and dehydrated alcohols
Silane coupling agent and graphene are added in the solution prepared according to the mass ratio of 1:2:100 for product mixing, and 50 DEG C are stirred at reflux
6 hours, under the action of silane coupling agent, surface is carried out to graphene and is modified, graphene is dispersed in the polymer improving
While, also enhance the interface interaction power of graphene and resin matrix.Alcohol is washed and is dried after product filtering, the modification that will be prepared
Graphene is uniformly mixed with phenolic resin by 1:5 mass ratio, is put into extruder and is squeezed out (120 DEG C of II area's temperature of extruder), is squeezed
Sheet stock obtains the modified phenolic resin curing agent of graphene after crushing grinding out.
The pigment is titanium dioxide；
Preparation method: by the modified phenolic resin curing agent of E-12 type epoxy resin, graphene, barium sulfate, mica powder, degassing
Wax, levelling agent, wetting agent, pigment are added in blender are uniformly mixed according to the ratio, then are squeezed out by double screw extruder, pressure
The modified double antiseptic powder coating of graphene is made in piece, cooling, broken, sieving.
Remarkable advantage of the invention:
Phenolic resin curing agent is introduced graphene-structured using graphene is modified by the present invention, so that heat resistance, anti-corrosion
Performance is obviously improved, and under the action of silane coupling agent, while raising graphene is dispersed in the polymer, is also increased
The interface interaction power of strong graphene and resin matrix, compounded combination between phenol-formaldehyde resin modified curing agent and auxiliary agent, outside and epoxy
After resin solidification, the protective performance of coating is superior, and corrosion resistance turns over several turn over more before modified.
