Description
Technical field
The invention belongs to technical field of chemical pigments, specifically a kind of rust-stabilising pigment and preparation method thereof.
Background technology
The coating that is used to prevent metallic corrosion is anticorrosive coating, and what wherein play main corrosion-resisting function is rust-stabilising pigment.At present, rust-stabilising pigment is divided into toxicity rust-stabilising pigment, low toxicity rust-stabilising pigment or non-poisonous antirust pigment.The toxicity rust-stabilising pigment mainly contains plumbous system and chromic salt, low toxicity or non-poisonous antirust pigment, as zinc molybdate, barium metaborate, zinc phosphate, phospho-molybdic acid calcium zinc, aluminium triphosphate, calcium exchange silicon-dioxide, wustite and their modified product and combined prod etc., its rustless property is close with toxicity rust-stabilising pigment performance.In recent years, aspect metal rust preventing, adopt phytic acid to be used to replace passivation and metal conditioners such as phosphatization and plating that chromic acid and phosphoric acid are respectively applied for metal, and obtain good result in actual applications, yet, notice with the phytic acid to be that compounds such as raw material production phytic acid zinc, aluminium, iron, calcium, barium are in high-efficiency rust-preventive pigment the industrial few people of rust-stabilising pigment.The applicant formerly develops non-poisonous antirust pigment, number of patent application " 200610041732.0 ", name is called " a kind of rust-stabilising pigment ", this rust-stabilising pigment contains phytate and mica or mica system or iron mica or ferrophosphorus powder filler, the weight ratio of phytate and mica or mica system or iron mica or ferrophosphorus powder filler is 1: 1-9, phytate and mica or mica system or iron mica or ferrophosphorus powder filler codeposition are mixed, its performance replaces traditional toxicity rust-stabilising pigment fully, can prevent effectively that the toxicity rust-stabilising pigment from causing severe contamination to environment, be detrimental to health.But its weak point is that rustless property, salt water resistance and package stability aspect and industrial requirement also have gap.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of rustless property height, salt water resistance, excellent storage stability and nontoxic, environmental protection, efficient, cheap rust-stabilising pigment.
Another technical problem that the present invention will solve is: the preparation method who proposes a kind of rustless property height, salt water resistance, excellent storage stability and nontoxic, environmental protection, efficient, cheap rust-stabilising pigment.
The present invention for the technical scheme that the technical solution problem adopts is: it is filler/or iron mica or ferrophosphorus powder that rust-stabilising pigment contains phytate, tannate and mica or mica, and said material proportional quantity weight part is as follows:
Phytate: the weight ratio of tannate is 10～20: 7～14, the mixture of phytate and tannate: mica or mica be filler/or the weight ratio of iron mica or ferrophosphorus powder be 1: 1～9.
Phytate of the present invention is phytic acid zinc, phytic acid aluminium, phytic acid iron, phytic acid ca, phytic acid manganese, phytic acid titanium, phytic acid nickel, phytic acid strontium or barium phytate.
Tannate of the present invention is Weibull zinc, tannal, ferric tannate, tannate of lime, Weibull manganese, Weibull titanium, Weibull nickel, Weibull strontium or Weibull barium.
The preparation method of rust-stabilising pigment of the present invention is:
With phytate, tannate and mica or mica be filler/or iron mica or ferrophosphorus powder filler be raw material, prepare rust-stabilising pigment as follows
1. mix: with mica or mica is filler/or iron mica or ferrophosphorus powder filler is added to phytate and tannate mixes, and stirs 1--5 hour;
2. surface treatment: carry out surface treatment with adding surface treatment agent in the liquid of mixing back;
3. wash after drying, granularity is 0.5～4 μ m, obtains containing phytic acid zinc, Weibull zinc and mica or mica and be filler/or the rust-stabilising pigment of iron mica or ferrophosphorus powder.
Said surface treatment agent is a silane coupling agent.
Said dosage of silane coupling agent is the 0.5-5% of raw material gross weight.
Beneficial effect of the present invention: rust-stabilising pigment of the present invention is owing to only contain phytic acid, the Weibull that extracts and nontoxic filler from the fruit Turkey-galls of plant, polymkeric substance is white or pale powder, toxic substances such as not leaded, chromium, cadmium, arsenic, when producing and using rust-stabilising pigment of the present invention, can not pollute, have environmental-protection function environment.In water-based and oiliness anticorrosive coating, all have outstanding rustless property, simultaneously hardness, toughness, the sticking power that strengthens coating is all had significant effect, therefore efficient.Coating (water-based, oiliness) excellent storage stability, neither multiviscosisty, also gel does not lump, and is good with other pigment, filler and resin (water-based, oiliness) amalgamation, can allocate arbitrarily.Have excellent especially rustless property and over-all properties.And the more existing rust-stabilising pigment of price is cheap, and its cost performance is fairly obvious.
Rust-stabilising pigment of the present invention and other rust-stabilising pigment are compared situation at rustless property, sticking power, hardness, package stability:
1, the contrast of the test in water soluble resin, schedule of operation is, with test with rust-stabilising pigment all by 10% weighing of total amount, the deionized water and stirring of adding 20% is evenly stand-by, to test again with after the steel plate rust cleaning degreasing, carry out the surface-coated oven dry, do dip test data such as following table with 3% sodium chloride solution again:
2, test contrast in non-water-soluble resin, schedule of operation is, to test with rust-stabilising pigment and in coating, press total amount 20% weighing, add then and grind in the resol evenly, to test again with after the steel plate rust cleaning degreasing, carry out surface-coated from doing 24 hours, do dip test data such as following table through 3% sodium chloride solution:
Above simultaneous test has only selected water-based and non-aqueous resin as filmogen, and does not add composition such as other any filler, and purpose is exactly to check each rust-stabilising pigment performance and other performance.Obviously be better than other rust-stabilising pigment by above test comparing result every performance of the present invention as can be seen.
