preparation example Construction

[0023] The preparation method of the modified rectorite clay used as a waterproof material provided in this embodiment comprises the following steps:

[0024] Step S101, selecting rectorite clay coarse concentrate raw material and crushing.

[0025] Rectorite is a kind of non-metallic mineral. In the embodiment of the present invention, the modified rectorite clay is prepared by modifying rectorite clay coarse concentrate as raw material. In this step, an appropriate amount of rectorite clay coarse concentrate raw material is selected and crushed according to the demand. Preferably, the rectorite content in the rectorite clay coarse concentrate raw material is 60-80%.

[0026] Step S102, adding a sodium salt modifier to the rectorite clay coarse concentrate.

[0027] The sodium salt modifier includes organic sodium salt modifier and / or inorganic sodium salt modifier, such as sodium carbonate, sodium fluoride, sodium chloride, sodium phosphate, sodium oxalate, etc., the sodium...

Abstract

The invention is suitable for the field of waterproof materials, and provides modified rectorite clay used as a waterproof material and a preparation method thereof. The method comprises the following steps of: selecting and crushing a rough concentrate raw material of rectorite clay; adding a sodium salt modifier to the rough concentrate raw material of rectorite clay; adding water into the rough concentrate raw material of rectorite clay and uniformly mixing and grinding to modify; and after modification, drying and crushing to prepare rectorite clay. The invention provides a preparation method of modified rectorite clay. The modified rectorite clay is a novel waterproof material. The modified rectorite clay provided by the invention enriches the variety of mineral waterproof materials, and the waterproof performance of the modified rectorite clay prepared by the method provided by the invention is superior to that of sodium bentonite.

Description

technical field [0001] The invention belongs to the field of waterproof materials, in particular to a modified rectorite clay used as a waterproof material and a preparation method thereof. Background technique [0002] Mineral-based waterproof materials have been paid more and more attention due to their long service life, no pollution, and easy construction, and have been applied in subways, construction, agriculture, forestry, water conservancy, and landfills. However, there are only a single variety of minerals used as waterproof materials at present. In practical applications, there is only one mineral species of sodium-based bentonite. However, there are few natural high-quality sodium-based bentonite resources in my country, and most of them are calcium-based bentonites. However, in practical applications, calcium-based bentonite sodium Chemical products also have problems such as poor waterproof performance. Contents of the invention [0003] In view of the above p...
