Abstract
The invention provides an epidesmine environment-friendly coating and a preparation method thereof. The epidesmine environment-friendly coating is prepared from epidesmine as a raw material into a powder product with the particle size of 800 meshes through elutriation, dry pulverization, acid activation and neutral drying. The invention has the advantages that the epidesmine prepared through modification and activation has great internal surface area, high absorption capacity and strong water absorbing capacity, the water absorbing rate reaches 73.47%, the volatilization of harmful volatiles in the coating can be effectively reduced, and the air is kept to be fresh, dry and free of toxic and side effects; the preparation process is simple and low cost; and a new approach is developed for the utilization of epidesmine mineral resources.
Description
Technical field
The present invention relates to coating, specifically stellerite environmental protection coating material and preparation method thereof.
Background technology
Environmental protection coating material refers to the performance index of coating products, and safety index is meeting under the prerequisite of product standard separately, meets the coating products of the technical requirements that the National Environmental famous special product proposes.
Stellerite (Stellerite) is mineral species in the zeolite family, its chemical ingredients (%): SiO258.76, Al2O314.13, CaO8.80, K2O0.11, Na2O0.18, Fe

The Application and Development of stellerite has caused concern at present, have as water purification agent, have as fertilizer additive, have as rubber reinforced additive, have as stellerite to prepare deodorant drier, there is not yet report but utilize stellerite to make environmental protection coating material.
Summary of the invention
The objective of the invention is to provide a kind of harmful volatile component few, cost is low, and the stellerite environmental protection coating material that has no side effect and preparation method thereof.
The technical scheme that realizes the object of the invention is:
Stellerite environmental protection coating material of the present invention is to be raw material by stellerite, makes the powder-like product of 800 order particle diameters through elutriation, dry grinding, acidic activated, neutral drying, and its preparation method comprises the steps:
(1) the natural parastilbite ore deposit is eluriated, dry grinding to 800 order is dried to water ratio＜0.5%;
(2) soak activation treatment with 10% sulfuric acid to being crushed to 800 purpose stellerite powder, stir simultaneously, soak time 2.5 hours, the volume ratio of sulfuric acid and stellerite powder is: 10% Liu Suan ︰ stellerite powder=4 ︰ 1;
(3) with the stellerite powder after the above-mentioned immersion with clear water wash to the pH value of solution be 6.7;
(4) powder drying is to water ratio＜0.5%, and drying temperature 100-130 ℃, packing is made.
Advantage of the present invention is: the stellerite of making through modified active, inner surface area is large, high adsorption capacity, water-retaining capacity are strong, water-intake rate reaches 73.47%, can effectively reduce the volatilization of harmful volatile component in the coating, keep air fresh, dry, and have no side effect, preparation technology is simple, and cost is low; For new approach has been opened up in the utilization of stellerite mineral products resource.
Embodiment
Eluriate it as main raw material in the natural parastilbite ore deposit of producing take the Ziyuan County, Guangxi, and dry grinding to 800 order is dried to water ratio＜0.5%; Then get 160L concentration and be 10% sulfuric acid and 40L is crushed to 800 purpose stellerite powder soaks, stir simultaneously soak time 2.5 hours; Again with the stellerite powder after the above-mentioned immersion with clear water wash to the pH value of solution be 6.7; Powder drying is to water ratio＜0.5%, and 100 ℃ to 130 ℃ of drying temperatures are packed and made the stellerite environmental protection coating material.
Claims (2)
