Abstract
The invention relates to a preparation technique an environment-friendly thickener for toothpaste. Water, sodium silicate and concentrated sulfuric acid are organically combined and react to produce the thickener for toothpaste. The thickener for toothpaste has the advantages of stable indexes and low energy consumption in the production process, saves abundant cost, and can easily implement industrialized popularization.
Description
Technical field
The invention belongs to chemical production technical field, specially refer to the preparation technology of toothpaste additive, is a kind of preparation technology of toothpaste environmental protection thickening material specifically.
Background technology
Thickening material claims again jelling agent, and toothpaste production field all needs to use thickening material, in traditional toothpaste thickening material production process, and the thickening material of output, often index is unstable, and product energy consumption is large, and poor effect causes production cost high.
Summary of the invention
The present invention be directed to above problem, a kind of preparation technology of toothpaste environmental protection thickening material is provided, the technique of this toothpaste environmental protection thickening material, the toothpaste thickening material of output, indices is stable, and production process energy consumption is little, saves great amount of cost, is easy to industrialization promotion.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
1) in reactor, add in advance 36.4m
3water and 2.63m
3water glass, after mixing, temperature is controlled between 38 ℃～42 ℃, adding concentration is 98% sulfuric acid, and pH value is controlled between 6.5～7;
2) by water glass according to 17.5m
3the flow of/h adds in reactor, and heats simultaneously, when temperature rises between 94 ℃～96 ℃, pH value reach 11～12 between time, keep temperature and pH value now, react 75～80 minutes;
3) sulfuric acid that is then 98% by concentration is according to 0.76m
3the flow of/h adds in reactor, and pH value is reached between 4.5～4.6, reacts 28～32 minutes;
4) stop temperature and keep, ageing obtained product after 20 minutes.
Beneficial effect of the present invention: the technique of this toothpaste environmental protection thickening material, the toothpaste thickening material of output, indices is stable, and production process energy consumption is little, saves great amount of cost, is easy to industrialization promotion.
Embodiment
1, in reactor, add in advance 36.4m
