Abstract
A process for preparing non-toxic antirust composite pigment from phosphide dregs includes such steps as neutralizing with alkaline substance, water washing until pH=5-7, drying, and pulverizing. It contains zinc phosphate (10-30%), iron phosphate (50-80%) and calcium phosphate (2-5%). Its advantages are reducing environmental pollution and low cost.
Description
Technical field
The present invention relates to a kind of preparation method of rust-stabilising pigment.
Background technology
Zinc phosphate is nontoxic, and favorable rust preventing effect extensively is used in all kinds of rust-inhibiting paints, but because of its production be by phosphoric acid and zinc oxide under certain condition chemical combination form, so price is more expensive; And when the bonderizing of steel, steel and iron member, produce the phosphatization slag, and not treated, just enter rivers, make the water quality eutrophication, pollute to environment.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the phosphatization slag to produce nontoxic composite antirust pigment.
The objective of the invention is to realize in the following way: a kind of method of utilizing the phosphatization slag to produce nontoxic composite antirust pigment: the phosphatization slag is washed to PH5-7 with the alkaline matter neutralization, is dried to water content then at 0.5%-2%; Being crushed to granularity then is 40 μ m-20 μ m, obtains a kind of zinc phosphate content at 10%-30%, and tertiary iron phosphate content is at 50%-80%, and calcium phosphate content is at the white of 2%-5% or the nontoxic composite antirust pigment of linen amorphous powder.
The present invention has following beneficial effect, and the one, made full use of when the bonderizing of steel, steel member, produce the phosphatization slag, make refuse obtain utilizing, reduced pollution on the environment; The 2nd, the nontoxic composite antirust pigment of producing is to utilize phosphatization slag waste material, so price is lower.
Embodiment
The present invention will be further described below in conjunction with embodiment:
A kind of method of utilizing the phosphatization slag to produce nontoxic composite antirust pigment, the phosphatization slag that will produce in the phosphorization treatment process of steel, steel and iron member etc. is washed to PH5-7 with the sodium hydroxide neutralization, is dried to water content then at 0.5%-2%; Being crushed to granularity then is 40 μ m-20 μ m, obtains a kind of zinc phosphate content at 10%-30%, and tertiary iron phosphate content is at 50%-80%, and calcium phosphate content is at the white of 2%-5% or the nontoxic composite antirust pigment of linen amorphous powder.
Claims (1)
1, a kind of method of utilizing the phosphatization slag to produce nontoxic composite antirust pigment is characterized in that:
The phosphatization slag is washed to PH5-7 with the alkaline matter neutralization, is dried to water content then at 0.5%-2%; Being crushed to granularity then is 40 μ m-20 μ m, obtains a kind of zinc phosphate content at 10%-30%, and tertiary iron phosphate content is at 50%-80%, and calcium phosphate content is at the white of 2%-5% or the nontoxic composite antirust pigment of linen amorphous powder.
