Abstract
The invention discloses a simple method for preparing superfine barium sulfate with the particle size of 100-350nm. The method comprises the following steps: 1) grinding barite into grains of 325 meshes by using a mineral barium sulfate Raymond mill; 2) adding the grinded material to make pulp with the solid content of 40-60%; 3) adding polyethylene glycol which accounts for 2% of the weight of the pulp, uniformly stirring and reacting for 10 minutes; 4) performing wet type superfine fine-grinding for 6 hours; 5) drying the material after the superfine fine-grinding. Superfine barium sulfate is prepared by pulping the barite powder, adding polyethylene glycol as a dispersing agent to disperse agglomerated barium sulfate grains in pulping, grinding a barium sulfate solution by using a wet grinding method and drying, wherein the average grain size is 100-350nm, and the application of a product is widened.
Description
Technical field
The present invention relates to the preparation method of barium sulfate, relate in particular to a kind of preparation method of ultra-fine barium sulfate.
Background technology
Because barium sulfate superfine powder has unique physicochemical property, in industries such as pigment, papermaking, medicine, rubber, ink, alite pastes, be widely applied.The powder size of barium sulfate product is thinner, and its surface adsorption ability is better, is easy to adsorb other material, can make the quality of product be easy to control, and makes product result of use good, and purposes is more extensive.
Summary of the invention
The present invention is directed to the problems referred to above and propose particle diameter at 100nm-350nm, and the preparation method of the simple a kind of ultra-fine barium sulfate of method.
Technical scheme of the present invention is: comprise the following steps:
1) by barite deposit, with barium sulfate Raymond mill abrasive dust to average grain, be, 325 orders;
2), the material after abrasive dust is added to water slurrying solid content 40%-60%;
3), the slurry after slurrying is added to 2% polyoxyethylene glycol of above-mentioned slurry weight, stir, reaction 10min;
4), above-mentioned material is carried out to the ultra-fine fine grinding of wet type 6 hours;
5), the material after the material after extra-fine grinding is dried and obtains ultra-fine barium sulfate pulverulent product.
The relative molecular mass of described polyoxyethylene glycol is 4000.
Described ultra-fine barium sulfate powder median size 100nm-350nm.
The present invention passes through the slurrying of barite abrasive dust, add polyoxyethylene glycol as dispersion agent, to be dispersed in the agglomerating particles of barium sulfate in slurrying, the present invention also grinds barium sulfate solution by wet grinding method, the dry ultra-fine barium sulfate powder of preparing, median size is 100nm-350nm, makes the purposes of product more extensive.
Embodiment:
The first step, by barite deposit, with barium sulfate Raymond mill abrasive dust to average grain, be 325 orders, be about to larger barite and be first broken into homogeneous bulky, can make described barite put into barium sulfate Raymond mill, then carry out abrasive dust, finally making material average grain is 325 orders.
Second step, add water to carry out slurrying in the described barite after abrasive dust, stir, making solid content is 40%-60%.
The 3rd step, the slurry after slurrying is added to the polyoxyethylene glycol that 2% relative molecular mass of above-mentioned slurry weight is 4000, stir, react 10min, can make the larger barium sulfate agglomerating particles in described slurry fully spread out.
The 4th step, the slurry of reacted barium sulfate in the 3rd step is carried out to the ultra-fine fine grinding of wet type 6 hours.
The 5th step, the material after the material after extra-fine grinding is dried and obtains ultra-fine barium sulfate pulverulent product.
The present invention is by the 3rd step, with described polyoxyethylene glycol as the dispersion agent larger particles that disperses to reunite in described barium sulfate slurry, then carry out the ultra-fine fine grinding of wet type described in the 4th step 6 hours, just can obtain barium sulfate particle diameter and reach 100nm-350nm, by dried, can make pulverulent product.Described pulverulent product is nano level, and its surface adsorption ability is better, is easy to adsorb other material, can make the quality of product be easy to control, and makes product result of use good, and purposes is more extensive.
