Embodiment 1

[0029] Example 1 Preparation of functional crystallization masterbatch

[0030] Method One

[0031] Take quicklime, put it in a beaker, add water to digest. Then it was stirred at constant temperature for 0.5h and aged at room temperature for 12 hours to form milk of lime. Then pour the prepared milk of lime into the carbonization reactor at one time. The temperature of the reactor is 80 degrees. A gas with a carbon dioxide concentration of 20% (V%) is introduced from the bottom of the reactor while stirring at a speed of 600r / min. After stirring for 1 hour, the material was poured out, and then placed in a drying oven at 105°C for 2 hours, and then taken out to obtain calcium carbonate powder.

[0032] Use deionized water to prepare Al(NO 3 ) 3 The aqueous solution A, where Al(NO 3 ) 3 The concentration is 60mol / L.

[0033] The aqueous solution B was prepared with deionized water, in which the concentration of NH4HCO3 was 60 mol / L and the concentration of polyethylene glycol was 5 ...

Embodiment 2

[0051] Example 2 Preparation of waterproof material containing functional crystalline masterbatch

[0052] The functional crystalline masterbatch of the present invention is used to prepare a waterproof material with the following formula:

[0053] Formula 1: Functional crystalline masterbatch 6%, methyl cellulose thickener 5%, anhydrous citric acid retarder 3%, ground quartz sand 30%, and the rest is cement. Wherein, the functional crystallization masterbatch is prepared by method one in Example 1.

[0054] Formulation 2: Functional crystallization masterbatch 8%, methyl cellulose thickener 5%, anhydrous citric acid retarder 3%, ground quartz sand 30%, and the rest is cement. The functional crystallization masterbatch is prepared by the second method in Example 2.

[0055] Formulation 3: Functional crystallization masterbatch 7%, methyl cellulose thickener 5%, anhydrous citric acid retarder 3%, ground quartz sand 30%, and the rest is cement. The functional crystal...

Abstract

The invention provides a functional crystallization master batch, a preparation method thereof and a waterproof material and belongs to the field of inorganic materials. The functional crystallization master batch is composed of a nanoscale calcium carbonate aluminum oxide composite powder body and chelated titanate. The preparation method includes preparing and mixing calcium carbonate powders and the nanoscale calcium carbonate aluminum oxide composite powder body. The waterproof material is composed of, by weight, 6-8% of the functional crystallization master batch, 4-6% of methyl cellulose thickening agents, 2-4% of anhydrous citric acids retarders, 25-35% of finely grinding quartz sands, and the balance cements. The functional crystallization master batch has excellent crystallization performance and usage performance, the preparation method is simple, low in production cost, safe in operation and suitable for industrial production, and the waterproof material has excellent impermeability pressure, compression strength and rupture strength.

Description

Technical field [0001] The invention belongs to the field of inorganic materials, and relates to a functional crystalline masterbatch, a preparation method thereof and a waterproof material, and belongs to a functional inorganic material. Background technique [0002] At present, in the field of inorganic materials, attention has been paid to the performance and preparation of functional crystalline masterbatch. The patent number is 200410058199.X, the invention patent named cement-based permeable crystalline waterproof material and its production process and construction method. It discloses a cement-based permeable crystalline waterproof material. The content of cement (inorganic material) is 50% of the total weight. -65%, the remaining components are active material 5.5-14.5%, methyl cellulose thickener 3.5-8.0%, anhydrous citric acid retarder 2.0-4.5%, and ground quartz sand 20-40%. But the problem is that the role of active materials is not ideal, that is, the performance i...
