Embodiment 1

[0029] (1) Grind and pulverize the layered mineral talc powder first, then add it to hydrochloric acid with a mass fraction of 10%, stir at a speed of 200rpm to make a suspension slurry, continue to stir and react at room temperature for 6h, filter, and use deionized Washed twice with water, then dried at 80°C to obtain activated layered minerals;

[0030] (2) Mix tetrabutyl titanate, absolute ethanol, and water with a mass ratio of 15:65:30 by stirring to form a mixed solution, and then add the activated layered minerals obtained in step (1) in an amount of mixing 15% of the mass of the solution to disperse the activated layered minerals to form a slurry, then stir at a speed of 900rpm, and slowly drop in the acetic acid solution. The time for adding acetic acid is controlled at 20 minutes, and the amount of acetic acid added is controlled at the pH value of the slurry. 5.5; then spray drying at 200°C, and firing at 400°C for 10 minutes, the formed titanium dioxide forms a ti...

Abstract

The invention provides a foaming master batch for a plastic floating plate for ecological restoration of the water body and a preparation method. According to the foaming master batch, activated layered minerals and tetrabutyl titanate are mixed and react, so that nano titanium dioxide is formed between layers and on the surface of a layered object, the nano titanium dioxide is tightly combined with the layered object, an interface is fully exposed, an excellent function of repairing pollutants by photocatalysis is achieved, and the foaming master batch is prepared by treating with a couplingagent and then mixing with EVA carrier resin, straw powder, a foaming agent and a lubricating agent, extruding and granulating. The floating plate prepared from the foaming master batch provided by the invention is fine and uniform in foam holes, low in density, not easy to sink and strong in pollutant adsorption effect, effectively overcomes the defects of easy loss, difficult separation and difficult recovery, and is large in layered carrier specific surface area, excellent in adsorption performance, more remarkable in water body purification effect, simple in preparation process, low in production cost, and capable of being popularized and applied.

Description
