Abstract
The invention discloses a preparation method of oxidation-resistant corrosion-resistant iron oxide black, which comprises the following steps: directly using an undried iron oxide black oxidation press cake prepared by a sodium hydroxide oxidation process, adding attapulgite accounting for 2-3 wt% of the iron oxide black press cake, antioxidant 168 accounting for 0.1-0.2 wt% of the iron oxide black press cake and zinc stearate accounting for 0.5-0.8 wt% of the iron oxide black press cake, grinding at the high speed of 2000-3000 rpm for 10-15 minutes, adding a proper amount of water, pulping for 20-30 minutes to obtain a 45-60% pulp, adding water-soluble accounting for 0.3-0.5 wt% of the pulp, sodium carboxymethyl cellulose accounting for 0.2-0.3 wt% of the pulp and zinc borate accounting for 0.3-0.4 wt% of the pulp, stirring for 20-30 minutes, milling by a colloid mill until the particle size is less than 50 mu m, drying, and pulverizing to obtain the finished product. The attapulgite and antioxidant 168 in the iron oxide black are added, so that the antioxidant 168 and the iron oxide black are combined together by using the dispersion and adsorption characteristics of the attapulgite, thereby enhancing the oxidation resistance; and the benzotriazole is added, thereby effectively enhancing the corrosion resistance of the iron oxide black.
Description
Technical field
The present invention relates to a kind of preparation method of anti-oxidation and antisepsis erosion iron oxide black, belong to the chemical color field.
Background technology
Iron pigment is as important inorganic color(ed)pigment, and its annual production occupies first of the inorganic color(ed)pigment.Because the reinforcement of world's environmental consciousness, the inorganic iron series pigments is nontoxic with it, do not have characteristics such as smell, pollution-free constantly replaces plumbous series, the serial poisonous mineral dyes of chromium such as pigment dyestuff and red lead, lead-chrome yellow.Iron oxide black is simple owing to chemical ingredients, nontoxic pollution-free, and chemical stability is strong, is widely used in the building trade paint.Phenomenons such as but existing iron oxide black oxidation-resistance and Corrosion Protection are poor, fade easily, variable color, thereby limited the use range of iron oxide black.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of preparation method of anti-oxidation and antisepsis erosion iron oxide black is provided.The iron oxide black good in oxidation resistance that this preparation method produces, difficulty is corroded, and is dispersed superior.
The technical solution used in the present invention is as follows:
A kind of preparation method of anti-oxidation and antisepsis erosion iron oxide black, the iron oxide black that it adopts the sodium hydroxide oxidation style to make, directly use the not oxidation filter cake of oven dry, add the attapulgite that is equivalent to iron oxide black filter cake weight 2-3%, the oxidation inhibitor 168 of 0.1-0.2% and the Zinic stearas of 0.5-0.8%, 2000-3000rpm ground at a high speed 10-15 minute, add an amount of water making beating 20-30 minute then, make the slurries that concentration is 45-60%, and the water-soluble benzotriazole of adding slurry weight 0.3-0.5%, the Xylo-Mucine of 0.2-0.3%, the zinc borate of 0.3-0.4%, stirred 20-30 minute, again by the colloidal mill defibrination to particle diameter less than 50 μ m, oven dry is played pulverizing and is finished product.
Beneficial effect of the present invention:
Black iron oxide pigment of the present invention has increased attapulgite, oxidation inhibitor 168, dispersion and characterization of adsorption by attapulgite combine oxidation inhibitor 168 and iron oxide black, increase oxidation-resistance, increased benzotriazole simultaneously, can improve the non-corrosibility of black iron oxide pigment effectively.
The iron oxide black that the present invention produces has superior heat resistance, well erosion resistance, oxidation-resistance and characteristics such as light absorptive is strong, tinting strength is high, consistency is good, good dispersity.
Embodiment
A kind of preparation method of anti-oxidation and antisepsis erosion iron oxide black, the iron oxide black that it adopts the sodium hydroxide oxidation style to make, directly use the not oxidation filter cake of oven dry, add the attapulgite that is equivalent to iron oxide black filter cake weight 2%, 0.15% oxidation inhibitor 168 and 0.6% Zinic stearas, 3000rpm ground at a high speed 10 minutes, add an amount of water making beating 20 minutes then, make concentration and be 55% slurries, and the water-soluble benzotriazole of adding slurry weight 0.4%, 0.2% Xylo-Mucine, 0.3% zinc borate, stirred 30 minutes, again by the colloidal mill defibrination to particle diameter less than 50 μ m, oven dry is played pulverizing and is finished product.
Black iron oxide pigment of the present invention has increased attapulgite, oxidation inhibitor 168, dispersion and characterization of adsorption by attapulgite combine oxidation inhibitor 168 and iron oxide black, increase oxidation-resistance, increased benzotriazole simultaneously, can improve the non-corrosibility of black iron oxide pigment effectively.
