Embodiment 1

[0028] The preparation process of the cement waterproof material of the present invention is as follows:

[0029] The preparation of the active mixture M: the content of each component in percentage by weight: ferric chloride 20%, sodium carbonate 20%, magnesium carbonate 5%, calcium carbonate 5%, strontium carbonate 0.5, and the rest are magnesium chloride for ingredients; Sodium, magnesium carbonate, calcium carbonate, strontium carbonate and magnesium chloride are all powders with a particle size of 270-500 mesh. After mixing the ingredients, stir evenly for 5-10 minutes to form an active mixture M;

[0030] Pour the refined quartz sand into the mixer and stir continuously. Add Portland cement during the mixing process. The particle size of the refined quartz sand is 0.1-0.5mm, and the particle size of the Portland cement powder is 270-500 mesh. , And then slowly add the above-mentioned active mixture M, and stir evenly for 5-10 minutes to obtain the cement waterproof material; ...

Embodiment 2

[0032] The weight percentages of the ingredients when preparing the active mixture M are: ferric chloride 30%, sodium carbonate 30%, magnesium carbonate 10%, calcium carbonate 10%, strontium carbonate 1%, and the rest are magnesium chloride.

[0033] The weight ratio of the three during the preparation of the cement waterproof material is: Portland cement: refined quartz sand: active mixture M=35:70:5.

[0034] The preparation method is the same as in Example 1.

Embodiment 3

[0036] The weight percentage of each component when preparing the active mixture M is: 25% ferric chloride, 25% sodium carbonate, 7% magnesium carbonate, 8% calcium carbonate, 0.8% strontium carbonate, and the rest is magnesium chloride.

[0037] The weight ratio of the three during the preparation of the cement waterproof material is: Portland cement: refined quartz sand: active mixture M=35:70:4.

[0038] The preparation method is the same as in Example 1.
