Bentonite inorganic gel for washing powder and preparation method thereof

Abstract

The invention discloses a preparation method of bentonite inorganic gel used in washing powder, comprising the following steps: (1) crushing to obtain bentonite particles; (2) fully dispersing the bentonite to obtain pulp A; (3) centrifuging the pulp A Separation and purification treatment to obtain slurry B; (4) adding inorganic salt to slurry B for sufficient modification to obtain viscous slurry C; (5) drying. The present invention not only can obtain high-purity and high-whiteness products, but also greatly improves the preparation efficiency and saves costs. The experiment proves that compared with the Chinese invention patent application CN108004054A, the cost is saved by about 25%, and a remarkable effect has been achieved; at the same time, The products of the present invention have better stain removal and softening properties.

Description

Bentonite inorganic gel for washing powder and preparation method thereof technical field The present invention relates to a kind of bentonite inorganic gel that is used for washing powder and preparation method thereof, belongs to daily washing articles technical field. Background technique [0002] At present, the vast majority of domestic washing powders use anionic surfactants as the main active substance. and supple The agent is mainly a cationic surfactant. Therefore, the existing washing powder (or washing liquid, detergent) and softener cannot be Otherwise, the anionic and cationic surfactants will react and cause the washing powder to fail. At present, people basically use laundry Machine to wash clothes, washing powder and softener cannot be added at the same time, which brings great trouble to the washing process. On the other hand, my country's bentonite resources are rich in species, and the reserves are huge, due to the unique nano-level layered stru...

Problems solved by technology

[0006] Yet there is following technical problem in above-mentioned technical scheme: (1) the concentration in the bentonite aqueous solution in its preparation method is relatively low, so the amount of the modified bentonite product that obtains in follow-up centrifugation, getting upper layer slurry, drying step is relatively few , the preparation efficiency is low, so the cost is high; this is very fatal for the washing powder additives in the fast-moving consumer goods industry; (2) due to the low concentration in the bentonite aqueous solution in its preparation method, the final The purity of modified bentonite products is low, so it is difficult to reflect the advantages of bentonite itself. In addition, due to the synergistic blending of modified siloxane and modified bentonite, the soft function is mainly reflected by modified polysiloxane. And the cost of modified polysiloxane is much higher than the cost of modified bentonite, and finally the cost of soft and functional particles has also been increased; (3) because modified bentonite is in the state of particles (particles), there are The problem of dispersibility and solubility, although it improves the dispersion and solubility of particles in water through sodium citrate, but its own dispersion and solubility are poor, and still need to be further improved
