Abstract
The invention discloses a kind of quick Ludox preparation methods of drying, including following S01, prepare Humic Acid Solution, between then progress acid-base accommodation makes its pH be 8 ~ 10；The Humic Acid Solution obtained in S01 is added drop-wise in silicon sol solution and is stirred by S02, forms humic acid/Ludox mixed system；S03 is washed with absolute ethyl alcohol after being filtered the humic acid obtained in S02/Ludox mixed system, finally the mixture being obtained by filtration is re-dispersed into polyamide emulsion hydrosol, and dry quick Ludox is made.The quick Ludox of drying prepared by the present invention, SiO2Particle is evenly dispersed in polymer emulsion, and product is cost-effective and has the characteristic of environmental protection.
Description
Technical field
The present invention relates to quick Ludox of a kind of drying and preparation method thereof, belong to technical field of nano material.
Background technology
Ludox is dispersion liquid of the nano level silica dioxide granule in water or in solvent, has large specific surface area, resistance to
The characteristics such as high temperature, anti-oxidant are a kind of ideal polymer emulsion increasings
Strong material.Due to the Nano-meter SiO_2 in Ludox2Particle surface needs to carry out hydrophobic change to it there are great amount of hydroxy group
Property, make SiO2Particle is can be uniformly dispersed in polymer emulsion.So far, main modifying agent mainly includes machine modifying agent
With metal modifiers two major classes.Organic modifiers are mainly silane coupling agent, but silane coupling agent can occur acutely in water
Hydrolysis-condensation reaction, lead to the generation of gel；Metal modifiers are the most commonly used is aluminium, tin, zinc and lead, but metal modifiers
Cost is higher, the problems such as in addition causing heavy metal pollution.In addition, common Ludox slow drying speed, causes the production cycle
Extend, is unfavorable for the raising of production efficiency.
Invention content
The technical problem to be solved by the present invention is to provide that a kind of Ludox arid cycle is short, SiO2Uniform particle dispersion
The preparation method of dry quick Ludox；Further, it is molten to provide a kind of cost-effective, environment-friendly type quick silicon of drying by the present invention
Glue and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of quick Ludox preparation method of drying, includes the following steps：
S01 prepares Humic Acid Solution, between then progress acid-base accommodation makes its pH be 8 ~ 10；
The Humic Acid Solution obtained in S01 is added drop-wise in silicon sol solution and is stirred by S02, and it is molten to form humic acid/silicon
Glue mixed system；
S03 is washed after being filtered the humic acid obtained in S02/Ludox mixed system with absolute ethyl alcohol, most
The mixture being obtained by filtration is re-dispersed into polyamide emulsion hydrosol afterwards, dry quick Ludox is made.
A concentration of 30 ~ 40wt% of the silicon sol solution.
The humic acid is extracted from the soil organism or water body organic matter.
The acid of the acid-base accommodation includes dilute hydrochloric acid or dust technology, and the alkali of the acid-base accommodation includes sodium hydroxide.
Between a concentration of 1000mg/L to the 2000mg/L of the humic acid.
Further include any one of the following conditions or multinomial in S02：
A. the reaction temperature being stirred is 40oC to 50oBetween C；
B. described to be stirred to be persistently stirred, the time being persistently stirred is at least 24 hours；
C. the drop rate of the humic acid is 5 ~ 10mL/min.
A kind of quick Ludox of drying, is made by aforementioned preparation process.
Beneficial effects of the present invention：A kind of rapid draing Ludox provided by the invention and preparation method thereof, polyamide breast
The setting of glue can shorten Ludox arid cycle, the Humic Acid Solution obtained in S01 is added drop-wise in silicon sol solution and is stirred
Mixing forms humic acid/Ludox mixed system, SiO2Particle can adsorb the humic acid with negative electrical charge, make itself band
There is negative electrical charge, increases SiO2Repulsive interaction between particle, final SiO2Evenly dispersed formed is not easy particle in water or in solvent
The Ludox stability reunite, generated is high；The humic acid is extracted from the soil organism or water body organic matter, and humic acid exists
It is widely present in nature, occupies the major part in natural organic matter, select material of the humic acid as modified silicasol, at
This is relatively low, and humic acid itself is extremely stablized, will not generation environment pollution, have the effect of environmental protection.
Specific implementation mode
The knot present invention is further described below, and following embodiment is only used for clearly illustrating the technical side of the present invention
Case, and not intended to limit the protection scope of the present invention.
