Problems solved by technology

It takes a long time to heat the suspension with a solid particle content of 2%-5% to such a high temperature, resulting in low production efficiency, and the solid particles of the bentonite suspension still have larger particles agglomerated together, and the activation is not sufficient

Embodiment 1

[0044] In a 1000ml beaker, add 20 g of bentonite with a montmorillonite content of 95%, add 500 ml of water, wherein the weight ratio of bentonite to water is 1: 25, stir for 20 minutes, then add 0.7 gram of sodium carbonate and disperse and stir for 30 minutes to make the bentonite Sufficient wetting and dispersion form sodium-based bentonite suspension, (the particle size distribution of high-pressure homogeneous sodium-based bentonite suspension is not as shown in Figure 1), this sodium-based bentonite suspension is used NiroNS1001L type high-pressure homogenizer at 100 standard atmospheres Lower homogenization, (the particle size distribution of sodium bentonite suspension after homogenization is shown in Figure 2). Then add the homogenized bentonite suspension to octadecyltrimethylammonium chloride solution to carry out organic activation reaction for 30 minutes, and then filter and dry to obtain high anti-sedimentation organic bentonite.

Embodiment 2

[0046] In the beaker of 1000ml, add centrifuged back montmorillonite content and be 95% bentonite suspension 500g, wherein the weight ratio of bentonite and water is 1: 25, stir for 20 minutes, then add 0.7 gram of sodium carbonate and disperse and stir for 30 minutes to make The bentonite is fully wetted and dispersed to form a sodium-based bentonite suspension, and the sodium-based bentonite suspension is homogenized at 200 standard atmospheres using a Niro NS1001L high-pressure homogenizer. (the particle size distribution of the sodium-based bentonite suspension after homogenization is shown in Figure 3) then the bentonite suspension that was homogenized was added to octadecyltrimethylammonium chloride solution to carry out organic activation reaction for 30 minutes, then filtered and dried to obtain the final product High anti-settling organic bentonite.

Embodiment 3

[0048] In the beaker of 1000ml, add centrifuged back montmorillonite content and be 95% bentonite suspension 500g, wherein the weight ratio of bentonite and water is 1: 25, stir for 20 minutes, then add 0.7 gram of sodium sulfate and disperse and stir for 30 minutes to make The bentonite is fully wetted and dispersed to form a sodium-based bentonite suspension, and the sodium-based bentonite suspension is homogenized at 1200 standard atmospheres using a Niro NS1001L high-pressure homogenizer. (the particle size distribution of the sodium bentonite suspension after homogenization is shown in Figure 4). Then, the homogenized bentonite suspension is added into octadecyl dimethyl benzyl ammonium chloride solution to carry out organic activation reaction for 30 minutes, and then filtered and dried to obtain high anti-sedimentation organic bentonite.

Abstract

The invention discloses a making method of anti-settling organic alta-mud through high-pressure homogeneous mechanism in the new technique of deep manufacturing of high-grade organic alta-mud, which comprises the following steps: 1) preparing low sodium sodium-base alta-mud suspension; 2) doing high-pressure isotrope for the suspension in the high temperature isotrope machine; obtaining sodium-based alta-mud suspension; 3) proceeding organic active reaction for the suspension to obtain the product with obvious anti-depositing property. The invention simplifies the operation with short time and high efficiency, which saves manufacturing cost and energy as a new technical flow path of large-scale industrialized high-grade organic alta-mud.

Description

technical field [0001] The invention relates to a preparation method of organic bentonite, in particular to a preparation method of high anti-sedimentation organic bentonite by using a high-pressure homogenizer, which belongs to a new technology for deep processing of high-grade organic bentonite. Background technique [0002] Organic bentonite is a new field of fine chemicals developed in recent years. It is widely used and is an indispensable additive in paint, coating, petroleum, cosmetics and other industries. Used as a leveling agent and fabric softener in the textile industry; used in emulsions, as a flow rate control agent; used in solvent-based inks, as thickening aids to adjust the viscosity and consistency of inks and prevent ink bleeding Dispersion, improve thixotropy; Used in oil drilling, it can be used as an additive for preparing oil-based mud to increase the consistency, dispersion and suspension of mud; Used as an anti-sedimentation additive in paints, it ca...
