preparation example Construction

[0036] The present invention also provides a method for preparing the above mortar, including:

[0037] S1: Weigh each raw material in parts by weight;

[0038] S2: Pour the cellulose ether, adsorbent, cement, water reducing agent and sand into the mixer, add an appropriate amount of water to stir and mix to obtain slurry A;

[0039] S3: Add the internal curing agent to the slurry A, stir evenly, and that's it.

[0040] In one of the embodiments, in steps S2 and S3, the stirring rate is 85-100 rpm / min, and the stirring time is 3.5-4 h.

Embodiment 1

[0043] A method for preparing the above-mentioned mortar includes:

[0044] S1: Weigh 10 parts of cellulose ether, 30 parts of Portland cement, 5 parts of activated carbon, 10 parts of lignosulfonate sodium salt water reducing agent, 10 parts of resin, 20 parts of river sand, and 10 parts of water according to parts by weight;

[0045] S2: Pour the cellulose ether, activated carbon, Portland cement, sodium lignosulfonate water reducing agent and river sand into the mixer, add 10 parts of water to stir and mix, the stirring rate is 85rpm / min, the stirring time For 3.5h, to obtain slurry A;

[0046] S3: Add resin to slurry A and stir evenly, where the stirring rate is 85 rpm / min, and the stirring time is 3.5 hours.

Embodiment 2

[0048] S1: Weigh 20 parts of cellulose ether, 35 parts of Portland cement, 10 parts of natural clay, 13 parts of aliphatic superplasticizer, 13 parts of resin, 23 parts of machine-made sand, and 15 parts of water according to parts by weight;

[0049] S2: Pour the cellulose ether, natural clay, Portland cement, aliphatic superplasticizer and machine-made sand into the mixer, add 15 parts of water for mixing, the mixing speed is 90rpm / min, and the mixing time is 4h , Obtain slurry A;

[0050] S3: Add resin to slurry A and stir evenly. The stirring speed is 85 rpm / min and the stirring time is 3.5 hours.

Abstract

The invention relates to anti-cracking dampproof mortar and a production method thereof. The anti-cracking dampproof mortar comprises, by weight, 10-20 parts of cellulose ether, 30-40 parts of cement,5-10 parts of an adsorbing agent, 10-15 parts of a water reducer, 10-15 parts of an internal curing agent, 20-25 parts of sand, and 10-20 parts of water. The cellulose ether enhances water-holding property and rheological property of the mortar; the water reducer and the internal curing agent can cooperate to reduce water usage, improve cracking strength and gain better water-holding property andcuring effect at the premise of maintaining mobility. In addition, the adsorbing agent added herein can greatly enhance water absorption of the mortar and can prevent water from seeping indoors.

Description

Technical field [0001] The present invention relates to the field of building materials, in particular to a crack-resistant and moisture-proof mortar and a preparation method thereof. Background technique [0002] Mortar is a cementing material used in building bricks. It is made by adding water to a certain proportion of sand and cementing materials. In the prior art, mortar and its preparation method have received a lot of reports. For example, a Chinese patent application number of 2017105404471 reports an anti-seepage and crack-resistant thermal insulation mortar and a preparation method thereof. The thermal insulation mortar is composed of the following components: The components are calculated in parts by weight: 40-60 parts of ordinary Portland cement, 25-35 parts of modified attapulgite powder, 30-40 parts of fly ash, 10-20 parts of diatomaceous earth, and 5 parts of polyimide fiber -15 parts, brucite powder 5-15 parts, plagioclase powder 5-15 parts, chabazite powder 5-1...
