Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of steel surface underloading with aqueous rusty self-lubricating coating and
Its preparation method.
Background technology
Steel corrosion, brings huge economic loss, in order to prevent steel corrosion, people have invented much to society every year
Method is used for the anti-corrosion of steel construction, in numerous anti-corrosion methods, coating process simple possible the most economic, patent
CN102838914A and CN104046149A provide it is a kind of can with the aqueous rust transformation primer of application over rust, using tannic acid with
The stable complex compound of iron ion generation, strengthens the adhesive force of coating, so as to suppress the growth of rusty scale.Such coating has anti-well
Rotten effect, but the coating surface formed is coarse, coefficient of friction is big, therefore such coating be not particularly suited for guide rail, transmission device or
The anti-corrosion on tumbler surface.
Occasion for much requiring low-friction coefficient, such as guide rail, transmission device, tumbler.The most frequently used is anti-
Rotten and antifriction method is to coat lubricating oil or lubricating grease on its surface.But lubricating oil, lubricating grease can cause environmental pollution, and should
With being limited in scope.It can hardly be used under high/low temperature, below-G conditions.Although the preparation of related lubricant has very big in recent years
Development, can effectively reduce coefficient of friction and comparatively safe environmental protection, it is sub- that such as patent CN103602362A introduces a kind of curing
The preparation method of iron-graphene composite Nano lubricant, patent CN101914409A introduces a kind of preparation of fire-resistant lubricants
Method.But can useful effect in the lubricant in equipment and few of easily getting rusty or got rusty.
Self-lubricating coating has the vapour bushing in application, such as self-lubricating bearing, piston-mode motor in many fields, very
Lubricating oil, lubricating grease are solved in big degree can not solve or non-serviceable occasion at all.In the prior art, self-lubricating coating
Generally it is made up of, coating is coated on metal substrate anti-wear additive, bonding agent, kollag and color stuffing when it is used
Special lubricant coating is formed after sintering curing.Patent CN102277082A provides a kind of self-lubricating sintering coating and painting
Coating method.Although it has good wearability, its application field is narrow, and construction method is complicated.
