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 ...

Abstract

The embodiment of the invention provides a polymer cement waterproof coating and a preparation method thereof. The embodiment of the invention provides a polymer cement waterproof coating. The polymer cement waterproof coating is composed of a liquid material and a powder material; the powder material comprises the components in 100 parts by weight: 40-50 parts of Portland cement, 1-3 parts of calcium aluminate, 1-2 parts of gypsum, 5-10 parts of quartz sand, 10-15 parts of quartz powder, 17.6-42 parts of heavy calcium carbonate, 0.2-0.5 part of a water reducing agent, 0.2-0.3 part of a dry powder defoaming agent and 0-1.7 parts of an anti-cracking material; the liquid material comprises a polymer emulsion, an additive and water. According to the polymer cement waterproof coating provided by the embodiment, the thickness of a coating film formed through single-time coating construction is increased, the coating construction cost of the coating is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of polymer cement waterproof coating, in particular to a polymer cement waterproof coating and a preparation method of the polymer cement waterproof coating. Background technique [0002] During construction and coating, the thicker the general polymer cement waterproof coating coating is, the easier it is for the coating film to crack during the film formation process. Therefore, it is necessary to reduce the coating thickness of each construction coating, which increases the construction cost and construction efficiency. [0003] Therefore, be badly in need of a kind of preparation method of new polymer cement waterproof coating and polymer cement waterproof coating. Contents of the invention [0004] The first aspect of the embodiment of the present application provides a polymer cement waterproof coating, which is composed of a liquid material and a powder material; [0005] According to 100 parts by weight of...
