Description
Technical field
The preparation method that the present invention relates to the colored silicon dioxide granule of a kind of toothpaste suspension.
Background technology
Colored silicon dioxide granule has the structure of porous and large surface area, physics and stable chemical performance, and color is beautiful, so being widely used in toothpaste, is the very important additive of one of toothpaste.Toothpaste adds silicon dioxide colour particles be possible not only to give the brand-new color of toothpaste and outward appearance, but also possess good clean-up performance, therefore very popular.But, the hardness of the colored silicon dioxide friction particle owing to selling in the market is general higher, relative density is bigger, not past any modifying and decorating, so when modulating toothpaste solution system, the suspension time of colored silicon dioxide granule is too short, is typically within 5min and almost can all be deposited to bottom solution, leverage colored silicon dioxide granule homogeneity in toothpaste and stability, limit the development of this toothpaste.
Such as publication number is CN100345755, publication date is that the Chinese patent of 2007.10.31 discloses " preparation method of a kind of nano silicon ", the method is to be joined by alkali silicate in the mixture of hydrocarbon component, surfactant and cosurfactant, form nanometer titania nanoparticle system of oil bag high concentration alkali metal silicate, make produced nano silicon be limited in micelle and carry out precipitation, it is then passed through washing, dries, obtain nanometer silicon dioxide particle.Silicon dioxide particle size distribution range obtained by this patent is narrow, can be used as toothpaste filler, but its hardness is higher, density is bigger, when modulating toothpaste solution system, suspension time is shorter, is all deposited to bottom solution, scattered homogeneity and less stable in toothpaste system within 5min.
Summary of the invention
The preparation method that the technical problem to be solved in the present invention is to provide the colored silicon dioxide granule of a kind of toothpaste suspension, the silicon dioxide granule prepared has certain degree of hardness and relative density less, in toothpaste modulation solution system, suspension time is at least up to half an hour, it is ensured that it is scattered homogeneity and stability in toothpaste system.
For solving above-mentioned technical problem, the technical scheme is that
The preparation method of the colored silicon dioxide granule of a kind of toothpaste suspension, comprises the following steps:
(1) in retort, add dilute sulfuric acid and stir, it is subsequently adding fully dispersed Aqueous Solutions of Polyethylene Glycol and sodium dodecyl sulfate aqueous solution, the weight of Aqueous Solutions of Polyethylene Glycol is the 0.05～0.1% of dilute sulfuric acid weight, and sodium dodecyl sulfate aqueous solution weight is the 0.05～0.1% of dilute sulfuric acid weight；
