Description

technical field [0001] The invention relates to the field of production of graphene-modified silicon-titanium nano heavy-duty anti-corrosion materials, in particular to a preparation method of graphene-modified silicon-titanium nano-polymer slurry and heavy-duty anti-corrosion materials. Background technique [0002] The existing technology mainly adopts the ball milling method. First, the output of a single machine is limited; second, the production cycle is long; third, the process quality is difficult to control; At the same time, because these resins have large molecular weight, long molecular chains, large steric hindrance, and limited number of functional groups, it is impossible to completely cross-link and graft with the nano-scale titanium surface. The role of fine fillers in molecular materials greatly reduces the effect, and free titanium is conductive, and the electrode potential is higher than that of iron. When the coating is abnormally damaged, galvanic corros...

[0002] The existing technology mainly adopts the ball milling method. First, the output of a single machine is limited; second, the production cycle is long; third, the process quality is difficult to control; At the same time, because these resins have large molecular weight, long molecular chains, large steric hindrance, and limited number of functional groups, it is impossible to completely cross-link and graft with the nano-scale titanium surface. The role of fine fillers in molecular materials greatly reduces the effect, and free titanium is conductive, and the electrode potential is higher than that of iron. When the coating is abnormally damaged, galvanic corrosion of large cathode and small anode is very easy to occur, making Increased corrosion

[0003] The existing graphene-modified titanium nanopolymer is divided into two steps. First, a graphene dispersion is prepared, and then a titanium nanoslurry is prepared. The two are combined to obtain a graphene-modified titanium nanopolymer. This physical It is difficult to combine the graphene flake layer structure with the titanium nanopolymer network, and the shielding effect is limited.
