Abstract

The invention relates to a multi-functional glass pumice and a preparation method thereof. Coatings are cured on the outer surface of the glass pumice and the inner walls of micropores of the glass pumice. The preparation method comprises the following steps of: sintering glass pumice, and blending a functional solution while sintering the glass pumice; then, attaching the prepared functional solution to the surface of the sintered glass pumice; and finally, enabling the functional solution layer attached to the glass pumice to stand and be cured at normal temperature, so as to form functional coatings on the outer surface of the glass pumice and the inner walls of the inner pores of the glass pumice. According to the multi-functional glass pumice and the preparation method thereof, different functions can be effectively realized through the functional coatings attached to the surface of the multi-functional glass pumice.

Description

technical field [0001] The invention relates to a glass pumice with multiple additional functions and a preparation method thereof. Background technique [0002] Glass pumice, because its micropores have the functions of filtration, water storage, and drainage, can be directly used as a filler to lay on paved roads or under the vegetation layer of green belts; at the same time, in order to achieve different functional purposes, special glass is required Pumice to achieve. For example, the Chinese patent CN201310281284.1 "A kind of foaming microporous glass pumice for deodorization and deodorization and its preparation method" applied by our company, CN201610452136.5 "A glass pumice planting nutrient soil capable of slow release of phosphate fertilizer and its Preparation method" and CN201310281273.3 "A foamed microporous glass pumice for chemical clarification and water quality filtration and its preparation method", which uses different formulas to make the glass pumice ob...
