Embodiment 1

[0013] The invention provides a surface modifier for active lime powder. The surface modifier for active lime powder includes complex compound, lye, carrier, ethanol, active agent and plaster of paris; wherein, relative to 1 weight part of complex compound, the content of lye 0.5 parts by weight, the amount of carrier is 0.2 parts by weight, the amount of ethanol is 1.5 parts by weight, the amount of active agent is 1.0 parts by weight, and the amount of plaster of paris is 2 parts by weight.

[0014] Specifically, in this embodiment, the complex compound is trioxide complex or trichloride complex, the mass percent concentration of the lye is 60%, and the lye is potassium hydroxide solution or sodium hydroxide solution.

[0015] In addition, the carrier is calcium oxide or calcium carbonate.

Embodiment 2

[0017] The invention provides an active lime powder surface modifier, which includes a complex compound, lye, carrier, ethanol, active agent and plaster of paris; wherein, relative to 1 part by weight of the complex compound, the lye The content is 0.8 parts by weight, the amount of carrier is 0.3 parts by weight, the amount of ethanol is 2 parts by weight, the amount of active agent is 1.0 parts by weight, and the amount of plaster of paris is 3 parts by weight.

[0018] Specifically, in this embodiment, the complex compound is trioxide complex or trichloride complex, the mass percent concentration of the lye is 60%, and the lye is potassium hydroxide solution or sodium hydroxide solution.

[0019] In addition, the carrier is calcium oxide or calcium carbonate.

[0020] In summary, the active lime powder surface modifier of the present invention has an activity of 400 and a hydration time longer than 60 minutes, so it has a very strong waterproof performance and can maintain ...

Abstract

The invention relates to an activated lime powder surface improver which comprises a complex, alkali liquor, a carrier, ethanol, an activator and calcined gypsum. Relative to 1 part by weight of the complex, the content of the alkali liquor is 0.5 to 0.8 part by weight, the using amount of the carrier is 0.2 to 0.3 part by weight, the using amount of the ethanol is 1.5 to 2 parts by weight, the using amount of the activator is 0.5 to 1.0 part by weight, and the using amount of the calcined gypsum is 2 to 3 parts by weight. According to the activated lime powder surface improver, the activity reaches 400, and can be kept high within a longer time; the hydration time is longer than 60 minutes, so that the waterproof performance is extremely high; a preparation method is simple, high in operability and environment-friendly, and has higher economic and social values.

Description

technical field [0001] The invention relates to the construction field, in particular to an active lime powder surface modifier. Background technique [0002] In recent years, with the continuous development of the construction industry and the increasing awareness of environmental protection, many traditional industrial products with low output and high energy consumption have gradually been eliminated. The existing common lime powder is easy to deliquesce due to contact with moisture in the air, thereby reducing the activity, so it is necessary to improve the common active lime powder. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a surface modifier of active lime powder, which has strong moisture resistance, good fluidity and easy access to raw materials. [0004] The present invention is achieved through the following technical scheme: provide a kind of active lime powder surface improver, act...
