Embodiment 1

[0020] The suspension provided by the present embodiment and its preparation method are as follows:

[0021] Including 0.05g attapulgite, 0.05g octadecyltrimethylammonium chloride, 50ml corn oil.

[0022] Control the temperature of the vegetable oil at 55°C, first add octadecyltrimethylammonium chloride to the vegetable oil, then add attapulgite to the beaker, and keep stirring at a speed of 300rpm, after the attapulgite is added , continue stirring for 15min.

[0023] Sonication:

[0024] (1) Ultrasound for 10 minutes at 68°C and 1000W;

[0025] (2) Lower the temperature to 50°C, and ultrasonicate for 20 minutes under the condition of 1800W;

[0026] (3) Lower the temperature to 30°C, and sonicate for 10 minutes under the condition of 2200W.

[0027] During gradient sonication, the temperature is decreased by 1°C per minute, and the ultrasonic power is increased by 80W per minute.

[0028] The resulting suspension can be stored stably for 90 days.

Embodiment 2

[0030] The suspension provided by the present embodiment and its preparation method are as follows:

[0031] Including 0.2g attapulgite, 0.07g octadecyltrimethylammonium chloride, 70ml soybean oil.

[0032] Control the temperature of the vegetable oil at 62°C, first add octadecyltrimethylammonium chloride to the vegetable oil, then add attapulgite to the beaker, and keep stirring at a speed of 400 rpm until the attapulgite is added After that, continue to stir for 20min.

[0033] Sonication: specifically:

[0034] (1) Ultrasound for 16 minutes at 70°C and 1200W;

[0035] (2) Lower the temperature to 53°C, and ultrasonicate for 25 minutes under the condition of 1900W;

[0036] (3) Lower the temperature to 37°C, and sonicate for 13 minutes under the condition of 2400W.

[0037] During gradient ultrasonic treatment, the temperature decreased by 1.5°C per minute, and the ultrasonic power increased by 90W per minute.

[0038] The resulting suspension can be stored stably for 9...

Embodiment 3

[0040] The suspension provided by the present embodiment and its preparation method are as follows:

[0041] Including 0.5g attapulgite, 0.1g octadecyltrimethylammonium chloride, 100ml peanut oil.

[0042] The temperature of the vegetable oil is controlled at 68°C. First, add octadecyltrimethylammonium chloride to the vegetable oil, then add attapulgite to the beaker, and keep stirring at a speed of 600 rpm. After the attapulgite is added After that, continue stirring for 30 min.

[0043] Sonication, specifically:

[0044] (1) The temperature is 73°C, under the condition of 1500W, ultrasonic for 20min;

[0045] (2) Lower the temperature to 60°C, and ultrasonicate for 30 minutes under the condition of 2000W;

[0046] (3) Lower the temperature to 40°C, and ultrasonicate for 15 minutes under the condition of 2500W.

[0047] During gradient sonication, the temperature was decreased by 2°C per minute, and the ultrasonic power was increased by 100W per minute.

Abstract

The invention discloses a highly suspended attapulgite vegetable oil suspension and a preparation method thereof. The highly suspended attapulgite vegetable oil suspension comprises the following components by weight: 0.05 to 0.5g of attapulgite, 0.05 to 0.1g of octadecyl trimethyl ammonium chloride, and 50 to 100ml of vegetable oil. The preparation method comprises the following steps: adding attapulgite, octadecyl trimethyl ammonium chloride into a beaker of vegetable oil, stirring, and then conducting ultrasonic treatment to obtain a suspension, i.e, the highly suspended attapulgite vegetable oil suspension. The suspension provided by the invention has the advantages of low cost, simple process, high suspending property and long stable period.

Description

technical field [0001] The invention relates to a high-suspension attapulgite vegetable oil suspension, which belongs to the field of materials. Background technique [0002] Attapulgite is a hydrous magnesium-aluminum-rich silicate mineral with a layered chain structure, and its chemical formula is: ((Mg,Al) 4 (Si) 8 (O,OH,H 2 O) 26 ·nH 2 O), whose basic structural unit is a rod-shaped single crystal composed of two layers of silicon-oxygen tetrahedron and one layer of magnesium-aluminum-oxygen octahedron, with a diameter of 20–70 nm and a length of 0.1–5.0 µm, which belongs to natural one-dimensional nanomaterials. Attapulgite is rich in reserves in my country, and the Jiangsu-Anhui attapulgite clay ore belt is one of the few attapulgite clay ore enrichment areas with high economic value in the world. Attapulgite has excellent physical and chemical properties unmatched by other clay minerals: adsorption properties, strong adsorption of heavy metal ions and organic ben...
