Description
Technical field
The invention belongs to technical field of coatings, more particularly, to a kind of preparation method of water-based antirusting paint operable with rust.
Background technology
In order to protect steel not corroded, extend its service life, carry out corrosion-proof coating to steel most passes through as one kind
Ji and effective method.In order to obtain excellent decay resistance, totally, otherwise the iron rust on steel must be removed before application
Due to the continuous expansion of iron rust paint film and antiseptic effect can be caused very poor, therefore, the processing of rust removing of iron rust is the weight of coating process
Part is wanted, the success or failure to corrosion-proof coating play conclusive effect.But many heavy constructions, bridge, ship etc. are multiple
Miscellaneous steel structure member is in maintenance process due to being limited by execution conditions, it is difficult to using mechanized construction method, can only adopt
By hand or electric tool is derusted, and its result necessarily has the residual of iron rust and various corrosion products, causes derusting difficult
To be guaranteed, construct, difficult, expense is huge.
Current domestic anticorrosion of steel structure still continues to use the old technique of progress application after sandblasting, although antiseptic effect is preferable,
There is also complex structural member to have dead angle, to expend electric energy height, dust pollution, noise pollution, cost height etc. all for sandblasting, ball blast technique
More shortcomings, therefore prepare the on rust paint that directly can be constructed on rust face and be very important.
Traditional technique uses phosphoric acid as transforming agent, although phosphoric acid can make corrosion be converted into phosphating coat, due to hydrogen
Separate out, paint film is easy to foaming, causes adhesive force to decline.It relies on the composite organic acid group being grafted on sub-micron macromolecule micelle,
Iron rust is reduced into the passivation composition with antirust ability, while molecular level occurs on whole metallic matrix for macromolecule micelle
Rearrange, by intersect film forming formed a fine and close big net because film layer directly with base material by chemical bonds, and
The molecular level of film layer, which rearranges, makes almost do not have space between particle, therefore film layer has high closeness, high derusting performance, height attached
Put forth effort, so that thoroughly the secondary problem of rustiness after solution derusting before application and derusting do not cause anticaustic in a short time thoroughly
Problem.
