preparation example Construction
[0070] Such as figure 2 As shown, the second aspect of the embodiment of the present application provides a method for preparing a polymer cement waterproof coating, the method comprising:
[0071] S11, uniformly mixing the Portland cement of the first part by weight, the filler of the second part by weight, and the anti-cracking material to obtain the first mixed powder;
[0072] S12, adding gypsum, calcium aluminate, heavy calcium mixed with a water reducer, and a dry powder defoamer to the first mixed powder to obtain a uniformly mixed second mixed powder;
[0073] S13, adding the third part by weight of Portland cement and the fourth part by weight of filler to the second mixed powder to obtain a uniformly mixed powder,
[0074] Wherein, the ratio of the first weight part to the third weight part is 1-1.5; the ratio of the second weight part to the fourth weight part is 1-1.5.
[0075] In some embodiments, the anti-crack material is selected from at least one of hollow ...
