Abstract
A process for preparing organic montmorillonite from Ca-base montmorillonite features that the raw material is organized by adding quaternary ammonium salt to it. Its advantages are simple process and less loss.
Description
Technical field
The present invention relates to be used for the preparation method of the organic montmorillonoid of polymer composite, belong to polymeric material field.
Background technology
Traditional preparation process is used for the method for the organic montmorillonoid of polymer composite, is that the ca-montmorillonite obtained opening a mine is (because of calcium ions Ca between its wafer
++Gain the name) after technologies such as washup purifying, obtain calcium-base montmorillonite.Detailed process is with the polynite thick mud of making soluble in water, 5% of adding polynite weight salt acid treatment after desanding is handled, wash thick mud again to neutral, filter after drying, get 300 purpose calcium-base montmorillonite powder through crushing screening again, and carry out the sodium glycosylation reaction, can make the sodium-based montmorillonite powder.This step also is to carry out in the aqueous solution, so last goods also need drying, pulverizing, again the sodium-based montmorillonite powder is carried out cation exchange reaction in the aqueous solution, introduce interlayer insets such as amino acid between wafer, dried product is organic montmorillonoid.Generally provide commodity market after the pulverizing with 300 purpose powder.This polynite powder that organises can be directly used in the preparation nano plastic, and promptly the polymer/nanoclay matrix material is the high-tech product in the present polymkeric substance.
Above-mentioned traditional preparation organic montmorillonoid process as shown in Figure 1.
The said process characteristics are that calcium-base montmorillonite needs to have made sodium-based montmorillonite after the sodium baseization, the reaction that just organises, and be applied to prepare polymer composite.This processing method will be dewatered sodium-based montmorillonite, needs to consume a large amount of energy.
Summary of the invention
The purpose of this invention is to provide a kind of with the calcium-base montmorillonite be raw material, without the sodium baseization directly preparation be used for the organic montmorillonoid preparation method of polymer composite.Method of the present invention is, adds quaternary ammonium salt in by the calcium-base montmorillonite after the hydrochloric acid washup, organises to handle to make the organic montmorillonoid that is used for polymer composite.
The process that the present invention obtains organic montmorillonoid as shown in Figure 2.Method of the present invention is to add quaternary ammonium salt in the calcium-base montmorillonite after the hydrochloric acid washup to organise to handle and make the organic montmorillonoid that is used for polymer composite.

Embodiment
Embodiment 1:
In the beaker of 2000ml, add calcium-base montmorillonite 100g, deionized water 400g, soak more than 2 hours, and shear slurrying with agitator, rotating speed should be greater than 500rmp, about 40 minutes of time, get upper strata suspension, add 5% hydrochloric acid of polynite weight again in the suspension, stirring reaction is 4 hours under normal temperature, washes thick mud then to neutral.
Getting above-mentioned thick mud (containing the heavy polynite of 10g) places in the 1000ml flask, add the organise palmityl trimethyl ammonium chloride of cationite 3.28g and the deionized water of 400ml, being heated to 80 ℃ stirred 2～4 hours down, be soup compound and lower floor's clear water on visible upper strata, the soup compound press filtration of getting the upper strata branch that anhydrates, in being crushed to 300 orders with after the filter cake oven dry below 150 ℃, promptly get organic montmorillonoid again.X ray detection, its interlamellar spacing d are carried out in sampling
0Be 40 dusts.
Embodiment 2:
In the beaker of 2000ml, add calcium-base montmorillonite 100g, deionized water 400g, soak more than 2 hours, and shear slurrying with agitator, rotating speed should be greater than 500rmp, about 40 minutes of time, get upper strata suspension, add 5% hydrochloric acid of polynite weight again in the suspension, stirring reaction is 4 hours under normal temperature, washes thick mud then to neutral.
Getting above-mentioned thick mud (containing the heavy polynite of 10g) places in the 1000ml flask, add organise cationite 4.47g octadecyl trimethyl ammonium chloride and 400ml deionized water, 80 ℃ are stirred down and get upper strata slurry and the press filtration branch that anhydrates after 2～4 hours, be crushed to 300 orders after the oven dry, promptly get organic montmorillonoid, x ray detection, its interlamellar spacing d are carried out in sampling
0Be 42 dusts.
Embodiment 3:
With example 1 and example 2 methods, the cationite that only will organise changes distearyl dimethyl ammonium chloride into.Its gained organic montmorillonoid is through x ray detection, interlamellar spacing d
0Be 45 dusts.
Embodiment 4:
With example 1 and example 2 methods, the cationite that will organise changes Trimethyllaurylammonium bromide into, and its gained organic montmorillonoid detects interlamellar spacing d through X ray
0Be 25 dusts.
