A kind of waterborne anti-rust coating compositions
Technical field
The present invention relates to a kind of rust-inhibiting paint, relate in particular to a kind of natural aqueous antirust paint composition.
Background technology
The direct economic loss that China causes due to metallic corrosion every year accounts for 4% of gross national product.Therefore the Anticorrosion Problems of metal more and more causes people's concern.In anticorrosive metal application techniques before, before japanning, pretreatment of metal surface accounts for 45% left and right of whole coating project total price.If can reduce or save rust cleaning, oil removing, the surface treatment procedure such as dewater, can significantly lower painting cost, also can greatly simplify enamelling process simultaneously, thereby reduce labor intensity and reduce the harm of rust dirt to human body.At present, in industry, a large amount of solvent-borne type conversion and prevention paint of rust constructions of using simply, can directly be brushed, and have saved this operation of rust cleaning.But formaldehyde, benzene, dimethylbenzene contained in solvent-borne type conversion and prevention paint of rust are all poisonous carcinogenic substances, and HUMAN HEALTH is caused to great hidden danger, can not meet people far away for the requirement of health environment-friendly.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is that a kind of waterborne anti-rust coating compositions nontoxic, pollution-free, with low cost, that rust-preventing characteristic is good that has is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of waterborne anti-rust coating compositions, is mixed and is formed by the composition of following weight percent:
Urethane resin 10%~20%;
Pure-acrylic emulsion 5%~8%;
Butanols 5~7%;
Calcium monofluorophosphate rust-proofing powder 5%~12%;
Vinylformic acid butyric acid 10%~20%;
Zinc phosphate 5%~7%;
Poly aluminium phosphate 5%~10%;
Deionized water surplus.
The advantage of waterborne anti-rust coating compositions of the present invention is: environment friendly and pollution-free, with low cost, take natural product as raw material, and wide material sources, cost is low; And the paint vehicle that the present invention makes has extremely strong sticking power to metallic surface, reach the object of protection hardware, thereby extend the work-ing life of hardware, can reach more than 20 years work-ing life.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
Waterborne anti-rust coating compositions of the present invention, is mixed and is formed by the composition of following weight percent:
Urethane resin 10%~20%;
Pure-acrylic emulsion 5%~8%;
Butanols 5~7%;
Calcium monofluorophosphate rust-proofing powder 5%~12%;
Vinylformic acid butyric acid 10%~20%;
Zinc phosphate 5%~7%;
Poly aluminium phosphate 5%~10%;
Deionized water surplus.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
