The stabilizer mainly comprises sodium silicate, magnesium silicate (or magnesium polysilicate, such as magnesium trisilicate), disodium Ethylene Diamine Tetraacetic Acid (EDTA), and organic polymer compound containing carboxyl, acyl or hydroxyl. The preparation method comprises the following steps: adding magnesium salt solution (such as magnesium sulfate or magnesium chloride) into sodium silicate solution with certain modulus, stirring to react completely, adding organic polymer solution and EDTA, and stirring.
Description
The present invention relates to a kind of compound method of SPC-D stablizer.This stablizer mainly contains water glass, Magnesium Silicate q-agent (or multi-silicate magnesium, as Magnesium Trisilicate), disodium ethylene diamine tetraacetate (EDTA) and contains the organic high molecular compound of carboxyl, acyl group or hydroxyl.Its compound method is: in the sodium silicate solution of certain modulus, add magnesium salt solution (as sal epsom or magnesium chloride), be stirred to react completely after, add the solution and the EDTA of organic high molecular compound again, stir.Add this stablizer, can simplify the production technique of SPC-D, obtain high stability product simultaneously.
SPC-D is a kind of mild oxidation agent, and molecular formula can be used 2Na
2CO
23H
2O
2Expression.Its instability is met heat or decomposition gradually under water function.Generally be to add Magnesium Silicate q-agent and EDTA as stablizer in the SPC-D production process, the SPC-D that makes like this can only be dry about 40 ℃.Also useful organic high molecular compound solution sprays fluidized granulating.By the SPC-D of these two kinds of method preparations, stability is generally 93～95%.
We once advised a kind of need not any stablizer, but add hydrophilic dehydration of organic solvent making the method for stable sodium percarbonate, the SPC-D that makes can be 120 ℃ of dryings, but its stability can only reach the level that above-mentioned two kinds of methods make product.
Adopt the described stablizer of present patent application, then stability can be brought up to more than 99.9%.
SPC-D stablizer with method preparation of the present invention has following characteristics:

(2) added the SPC-D of this stablizer, after from reaction slurry, separating, do not needed, can not have significant decomposition by dry face under up to 120 ℃ temperature with hydrophilic organic solvent (as ethanol etc.) dehydration.
Below provide 5 embodiment.In the preparation stablizer,,, can obtain good effect as can be seen no matter also be to use above-mentioned which kind of macromolecular compound no matter be to generate Magnesium Silicate q-agent or multi-silicate magnesium.Equally, when stating stablizer production SPC-D in the use, no matter whether sodium carbonate solution is made with extra care (is used Na
2S removes the foreign metal ion), perhaps, whether use hydrophilic dehydration of organic solvent such as ethanol, can both obtain high stability product.
