Abstract
The invention discloses a silicon dioxide suspending liquid, which comprises the following components by weight: 10-50 parts of silica micropowder, 0.05-0.75 parts of dispersant, 0.05-0.30 parts of xanthan gum and 50-90 parts of water. According to the invention, the silicon dioxide suspending liquid takes silica micropowder as a base, takes sodium polyacrylate or sodium polymethacrylate as a dispersant, and uses the suspension stability of the xanthan gum. The silicon dioxide suspending liquid has the advantages of high solid content and stable storage, and is suitable for a plurality of operation modes such as pumping and spraying, the preparation process is convenient, and the application range of the pH value is wide.
Description
Technical field
The present invention relates to a kind of suspension, relate in particular to a kind of silica suspension.
Background technology
The aqueous slurry of silica or suspension have been applied to many fields, particularly refractory material, papermaking, concrete industry.The silica suspension that present every profession and trade is used all hopes to have higher solid content, and the suspension of high solids content has higher viscosity usually, causes to use difficulty, and the storage time is restricted the phenomenon that deposition is arranged or flocculate.Silica suspension is mostly again preferably is through strict, complicated production technology for commercial high solids content, storge quality, through multiple dispersant such as organic and inorganic, and strict Acidity of Aikalinity (pH value), the current potential property of holding slurry, manufacturing cost is higher.
Summary of the invention
Deficiency to the prior art existence.Technical problem to be solved by this invention provides a kind of silica suspension, and high solids content, stable storing are suitable for several work modes such as pumping, spraying, and be easy to make.
Silica suspension is made up of following component: silicon powder 10-50 part, dispersant 0.05-0.75 part, xanthans 0.05-0.30 part and water 50-90 part by weight.
Preferably, said silica suspension is made up of following component: silicon powder 30-40 part, dispersant 0.10-0.40 part, xanthans 0.10-0.20 part and water 70-80 part by weight.
Said dispersant is a kind of or its mixture in Sodium Polyacrylate and the sodium polymethacrylate.
Silica suspension of the present invention is the basis with the silicon powder, and said silicon powder is by natural quartz (SiO
2) or vitreous silica (natural quartz is through high-temperature fusion, cooled amorphous state SiO
2) fine silica powder that forms through multiple tracks processes such as broken, ball milling (or vibration, airflow milling), flotation, pickling purification, high purity water processing.Fineness is less than 1 micron account for more than 80%, and average grain diameter is at the 0.1-0.3 micron, and specific area is 20-28m
2/ g.
Using polypropylene acid sodium of the present invention or sodium polymethacrylate are as dispersant.As a kind of new and effective liquefacient, Sodium Polyacrylate or sodium polymethacrylate are applied in the multiple dispersion more and more.The inventor finds, this dispersant, to silicon-dioxide powdery to separate the effect of coagulating remarkable especially, extremely the Sodium Polyacrylate of trace just can play good peptizaiton like 0.05wt%, even and the long-term storage of process the phenomenon of flocculating can not appear.
Xanthans according to the invention is claimed yellow glue, xanthan gum, yellow unit cell polysaccharide again, is a kind of monospore polysaccharide that is produced by false xanthomonas fermentation.Xanthans colloidal sol molecular energy forms the ultra banded spiral EVA that combines, and constitutes the network structure of fragile similar glue, so can support the form of solid particle, drop and bubble, demonstrates very strong stable emulsifying effect and higher suspension ability.In the present invention, mainly utilized this performance of xanthans, carried out suspending stabilized the silicon powder dispersion.
Silica suspension of the present invention can adopt industry conventional method to be prepared from, and for example: earlier dispersant and xanthans are dissolved in the water, add silicon powder again, high-speed stirred is disperseed, and can make silica suspension after old one day.
Among the present invention, less demanding to pH value, in the PH=3-10 broad range, all can be adjusted to stabilising system, look the applied environment of suspension and allocate.
Need to prove that for improving other performances, silica suspension of the present invention can be introduced additives such as antifoaming agent, anticorrisive agent in right amount to improve its corresponding serviceability.
Silica suspension of the present invention, high solids content, stable storing are suitable for several work modes such as pumping, spraying, and easy to make, and the pH value scope of application is wide.
