Abstract

Bentonite activity thickens anti-settling rheological agent, by raw material weight ratio：Highly purified bentonite 100 of the granularity less than 50 microns, octadecyltrimethylammonium chloride 15~20, stearyl dimethyl benzyl ammonium chloride 15~20, deionized water 200~300 is aggregated dries；Bentonite activity thickens the preparation method of anti-settling rheological agent, and its step are as follows：1）, by raw material stirring and emulsifying 20~30 minutes；2）, reactor tank be warming up to 60~80 DEG C be stirred for 20~30 minutes；3）, reactor tank heats up 100 DEG C to be stirred into raw material in reactor tank thick and is dried into block stock, 4）, block stock be ground into powder of the granularity less than 58 microns get product.It is suitable for the swelling native produce of current sealing wax system, and thickening result of prevention is good.

Description

Bentonite activity thickens anti-settling rheological agent and preparation method thereof
Technical field
The present invention relates to rheological agent technical fields, more specifically to a kind of rheological agent that can play thickening result of prevention And preparation method thereof.
Background technique
The organic solvent volatilization of solvent based coating is the main cause that coating industry causes atmosphere pollution.For this purpose, the science and technology of country Long-and Medium-term Development planning, it was also proposed that widely popularize and use environmentally friendly sealing wax.Many policies and regulations relevant to sealing wax go out at present Nowadays platform mostly is being proposed the explicit order forbidden from suggesting to limitation.In view of such status, my company is started to develop Suitable for the swelling native produce of current sealing wax system, dicyandiamide solution usual in sealing wax formula is the mixing of alcohol ether and water at present Solvent, and tradition is organic or aqueous bentonite cannot all play the role of effectively thickening in this mixed solvent system it is anti-settling.
Summary of the invention
The purpose of the present invention is to the deficiencies of the prior art, and provide bentonite activity and thicken anti-settling rheological agent, it Suitable for the swelling native produce of current sealing wax system, it is good to thicken result of prevention.
Technology solution of the invention is as follows：
Bentonite activity thickens anti-settling rheological agent, by raw material weight ratio：Highly purified bentonite 100 of the granularity less than 50 microns Gram, 15~20 grams of octadecyltrimethylammonium chloride, 15~20 grams of stearyl dimethyl benzyl ammonium chloride, deionized water 200 ~300 grams aggregated to dry；The highly purified bentonitic purity is not less than 99% by mass, product chemical index It is as follows：
Appearance：The flowable sprills of white；Fugitive constituent (105 DEG C, 2 hours)：≤3.5%；
Granularity (<76 μm or 200 mesh)：≥98%；
Specific gravity（25℃）：1.6；
Calcination loss (850-900 DEG C)：≤40%；
15% colloid viscosity（Butyl glycol ether：Water=1:1 mixed solvent）≥3000mpa.s.
Bentonite activity thickens the preparation method of anti-settling rheological agent, and its step are as follows：
1）, claim that 100 grams of highly purified bentonite, octadecyltrimethylammonium chloride are added into stainless steel reaction tank by weight 15~20 grams, 15~20 grams of stearyl dimethyl benzyl ammonium chloride, 200~300 grams of deionized water, 20~30 points of stirring and emulsifying Clock；
2）, reactor tank be warming up to 60~80 DEG C be stirred for 20~30 minutes；
3）, by reactor tank heating 100 DEG C raw material in reactor tank stirred into thick and be dried into block stock；
4）, block stock be ground into powder of the granularity less than 58 microns get product.
The beneficial effects of the present invention are：
It is suitable for the swelling native produce of current sealing wax system, and thickening result of prevention is good.
Specific embodiment

Appearance：The flowable sprills of white；Fugitive constituent (105 DEG C, 2 hours)：≤3.5%；
Granularity (<76 μm or 200 mesh)：≥98%；
Specific gravity（25℃）：1.6；
Calcination loss (850-900 DEG C)：≤40%；
15% colloid viscosity（Butyl glycol ether：Water=1:1 mixed solvent）≥3000mpa.s.
Bentonite activity thickens the preparation method of anti-settling rheological agent, and its step are as follows：
1）, claim that 100 grams of highly purified bentonite, octadecyltrimethylammonium chloride are added into stainless steel reaction tank by weight 15~20 grams, 15~20 grams of stearyl dimethyl benzyl ammonium chloride, 200~300 grams of deionized water, 20~30 points of stirring and emulsifying Clock；
2）, reactor tank be warming up to 60~80 DEG C be stirred for 20~30 minutes；
3）, by reactor tank heating 100 DEG C raw material in reactor tank stirred into thick and be dried into block stock；
4）, block stock be ground into powder of the granularity less than 58 microns get product.
