Embodiment 1

[0011] Alkaline calcium-based bentonite: methacrylic acid bentonite: ethanol: a certain mass ratio of cyclohexane is mixed step by step, the alkaline earth is placed in a three-necked flask, and 2 / 3 of the total amount of cyclohexane added is added to the three-necked flask. Use 100W ultrasonic power to ultrasonically disperse at room temperature for 10 minutes; after the ultrasonic dispersion is completed, place the three-neck flask in a water bath, stir and heat the magnetic particles in a constant temperature water bath at 80°C, and when the temperature is constant, drop methacrylic acid, The mixture of ethanol and the remaining cyclohexane was kept at a rate of 1 drop / s, and then reacted with water for 2 hours, the reactant was filtered by suction, dried at 105°C for 16 hours, and naturally cooled to room temperature to obtain the methacrylic acid bentonite , after scanning electron microscope image 3 , prepared a group of methacrylic acid bentonite without ultrasonic dis...

Abstract

The invention relates to a preparation method of methacrylic acid bentonite with a structure of vertically and crossly distributed lamellas. The preparation method of methacrylic acid bentonite is characterized in that alkaline calcium base soil and methacrylic acid act as raw materials, and cyclohexene acts as a dispersing agent. The preparation method comprises the following steps: putting alkaline calcium base bentonite into a three-opening flask, adding a proper amount of cyclohexene, and carrying out ultrasonic dispersion with the power of 50-900W for 1-150 minutes; then putting the three-opening flask into a water bath pot at 30-100 DEG C, and carrying out thermostatic waterbath mechanical stirring, adding a mixed solution of methacrylic acid, alcohol and residual cyclohexene dropwise, then condensing and backflowing, carrying out water diversion reaction for 0.5-12 hours, carrying out suction filtration, drying, and cooling naturally to room temperature, thereby obtaining the methacrylic acid bentonite. The organic content of methacrylic acid bentonite is as high as 30%-50%. The methacrylic acid bentonite is novel organic bentonite. Meanwhile, the preparation method enables the reaction to be more uniform and full, so that the favorable bentonite with vertically, crossly and uniformly distributed lamellas can be obtained, and moreover, the organic content is as high as 44.1%.

Description

technical field [0001] The invention belongs to the field of composite material preparation, and in particular relates to a preparation method of methacrylic acid bentonite whose structure is vertical intersecting distribution of sheets. Background technique [0002] Organic acids have a wide range of sources and a wide variety of products. Different types of products contain organic groups with different functions, which makes up for the lack of single function of the original organic bentonite and expands the application field of bentonite. However, the structure of the organic acid bentonite currently prepared Disordered arrangement and disordered structure impede the application of organic acid bentonite to a certain extent. The invention utilizes methacrylic acid to prepare methacrylic acid bentonite with sheets vertically intersecting. At the same time, although methacrylic acid is an organic acid, it is a little more lipophilic than acrylic acid, and a little more hyd...
