Abstract
The invention discloses a kind of self-lubricating renovation agent, including following main component：Vinyl polysilazane resin, aluminium powder, zinc powder, Graphene, polyimides, curing agent and solvent；Add Graphene; and by itself and vinyl polysilazane resin, the common powder ball milling of polyimides; vinyl polysilazane resin, polyimides are dispersed in graphenic surface; crosslinking is so controlled in film forming procedure is sprayed; film forming physical and mechanical properties is more excellent; glossiness, guarantor's light unfading are good, can quickly repair the protective coating that object surface is damaged, and product is small to environmental danger.
Description
Technical field
The present invention relates to protective coating recovery technique field, more particularly to a kind of self-lubricating healant.
Background technology
Object exposure is susceptible to oxidation in atmosphere, often increases by one layer of protective coating using in object surface.Zinc and
Aluminium aoxidizes generation one layer of diaphragm of densification --- zinc oxide and aluminum oxide in atmosphere, so often selecting zinc in the prior art
With aluminium as the protective coating of object surface to prevent object from being oxidized, blue white zine is often further selected during plating
Used as protective coating, the local damage of object surface often results in protective coating failure, causes object metal in itself local rotten
Erosion or plastics local ageing etc., object are difficult to keep attractive in appearance, therefore the protective coating to object surface safeguards particularly significant in time.
The content of the invention
Based on the technical problem that background technology is present, the present invention proposes a kind of self-lubricating renovation agent and preparation method thereof.
Technical scheme is as follows：
A kind of self-lubricating renovation agent, including following percentage by weight main component：
Vinyl polysilazane resin 12-20%；
Aluminium powder 8-15%
Zinc powder 10-20%
Graphene 0.03-0.05%
Polyimides 15-25%
Curing agent 3-5%
Balance of solvent.
Preferably, described curing agent is diethylenetriamine.
Preferably, the particle diameter of described aluminium powder and zinc powder is 250 mesh.
Preferably, described solvent is the mixture of ethyl acetate and DMF.
A kind of self-lubricating renovation agent and preparation method thereof, comprises the following steps：
A, vinyl polysilazane resin, polyimides and Graphene are carried out powder ball milling, cross 250 mesh sieves；
B, above-mentioned raw materials are dissolved in solvent and aluminium powder is added and zinc powder, be uniformly dispersed；
C, when using, curing agent is added in above-mentioned raw materials, after being well mixed.
The present invention is advantageous in that：Add Graphene in the present invention, and by it with vinyl polysilazane resin, it is poly-
The common powder ball milling of acid imide, graphenic surface is dispersed in by vinyl polysilazane resin, polyimides, so in spray
Control crosslinking in film forming procedure is applied, film forming physical and mechanical properties is more excellent, and glossiness, guarantor's light unfading are good, can quickly repair
The protective coating that object surface is damaged, product is small to environmental danger.
