[0048] Preparation of Purified Sodium Bentonite

[0049]The preparation process of purified sodium-based bentonite is as follows: Naturally dry and crush the raw sodium-based bentonite, then dry it by airflow, and then grind it by Raymond mill, and then obtain purified sodium-based bentonite by wind selection and classification by airflow classifier, performance index for E Na+ / CEC×100%≥50%.

[0050] Preparation Example

[0051] Step a: Weigh 15g of aluminum metaphosphate, 30g of NaOH, 10g of sodium molybdate, and 30g of deionized water, and add them into a reactor at 90°C, stir and keep the temperature constant for 10 minutes.

[0052] Step b: Put 300g of deionized water in the above-mentioned reactor and mechanically stir at 100-300rpm at room temperature.

[0053] Step c: Weigh 1161g of deionized water and put it in another larger reactor at room temperature, add 4g of surfactant H140 and stir slowly at 30-50rpm, add the catalyst prepared in the above step b until mixed...

Abstract

The invention relates to a permeable reactive waterproof anticorrosion additive and a mortar combination containing the additive, in particular to a permeable reactive waterproof anticorrosion additive, excellent in waterproofing and anti-corrosion performances, simple for construction and permeable and reactive. The permeable reactive waterproof anticorrosion additive can serve as a waterproof anticorrosion barrier for newly-built structures, and the problem that the existing structures already suffer water leakage is solved.

Description

technical field [0001] The invention relates to an osmotic reaction type waterproof and anticorrosion additive and a mortar composition containing the additive. Specifically, the present invention relates to an osmotic reaction type waterproof and anticorrosion additive with excellent waterproof and anticorrosion performance, simple construction, permeability and reactivity. Anti-corrosion additive, the invention also relates to a mortar composition containing the additive. Background technique [0002] In our country, huge property losses are caused by the leakage of underground structures every year, and the leakage of underground structures may also bring serious harm to environmental safety, for example, the benzene pollution incident in a certain place. In the existing underground waterproofing technology, methods such as admixture structure self-waterproofing, membrane waterproofing, and film waterproofing are usually used for comprehensive disposal. Due to the specia...
