Problems solved by technology

[0010] Existing waterproof mortars either have poor weather resistance, or the later strength cannot keep up, or the operation method is complicated. Therefore, it is necessary to develop a waterproof mortar with good waterproof and anti-seepage ability, and high later strength, which is easy to operate and use.

Embodiment 1

[0046] The raw material of the waterproof mortar component with inorganic minerals as the main filler described in Example 1 of the present invention is:

[0047] 300 parts of ordinary Portland cement, 587 parts of graded quartz sand, 40 parts of attapulgite, 5 parts of bentonite, 3 parts of early strengthening agent calcium formate, 10 parts of active aluminum salt aluminum sulfate, thickening and moisturizing agent hydroxymethyl cellulose 3 parts, 1 part of retarder sodium citrate, 1 part of antifreeze agent magnesium chloride, 30 parts of silica powder, 20 parts of active activator sodium silicate, and water 240-350. The grading situation of the quartz sand is as follows: coarse-grained quartz sand is passed through a 40-80 mesh sieve, and fine-grained quartz sand is passed through 80-120 mesh, and the ratio of the coarse sand to the fine sand is 2:1.

[0048] Put the above-mentioned component materials in a mixing tank and mix them evenly for 20 minutes. According to the rated ...

Embodiment 2

[0050] The raw material of the waterproof mortar component with inorganic minerals as the main filler described in Example 2 of the present invention is:

[0051] 350 parts of ordinary Portland cement, 600 parts of graded quartz sand, 10 parts of attapulgite, 3 parts of thickening and moisturizing agent hydroxypropyl methylcellulose, 30 parts of active aluminum salt aluminum sulfate, 1 part of retarder tartaric acid, 3 parts of Nai-series water reducing agent, 3 parts of early intensifier calcium formate, with 180-280 parts of water. The grading situation of the quartz sand is as follows: coarse-grained quartz sand is passed through a 40-80 mesh sieve, and fine-grained quartz sand is passed through 80-120 mesh, and the ratio of the coarse sand to the fine sand is 2:1.

[0052] Put the above-mentioned component materials in a mixing tank and mix them evenly for 20 minutes. According to the rated weight, pack them into a packaging bag with an inner film. The relative humidity of the ...

Embodiment 3

[0054] The raw material of the waterproof mortar component with inorganic minerals as the main filler described in Example 3 of the present invention is:

[0055] Ordinary Portland cement 380 parts, graded quartz sand 442, attapulgite 100, thickening and moisturizing agent hydroxypropyl methylcellulose 3 parts, silicon powder 20 parts, active aluminum salt aluminum potassium sulfate 50 parts, early strengthening agent 5 parts of sodium carbonate. The grading situation of the quartz sand is as follows: coarse-grained quartz sand is passed through a 40-80 mesh sieve, and fine-grained quartz sand is passed through 80-120 mesh, and the ratio of the coarse sand to the fine sand is 2:1.

[0056] Put the above-mentioned component materials in a mixing tank and mix them evenly for 20 minutes. According to the rated weight, pack them into a packaging bag with an inner film. The relative humidity of the environment is less than 80%. The inner film is sealed and the outside is sealed to avoid...

Abstract

The invention discloses waterproof mortar taking inorganic minerals as main filler. The waterproof mortar is prepared from raw materials of components in percentage by weight as follows: 15%-45% of Portland cement, 1%-10% of attapulgite or modified attapulgite, 1%-7% of active aluminium salt, 0-3% of bentonite, 40%-70% of graded sand, 0.3%-1% of a thickening and moisturizing agent, 0.1%-1% of an early enhancer, 0-1.5% of a retarder and 0-10% of an active activator. The waterproof mortar has good waterproof and anti-seepage performance and is higher in early strength and good in weather resistance, and the later strength is also greatly improved.

Description

Technical field [0001] The invention belongs to the field of building decoration materials, and specifically relates to a waterproof mortar with inorganic minerals as main fillers. Background technique [0002] Leakage of buildings will not only damage the interior decoration and equipment of the project, but also seriously damage the structure of the project, causing it to lose its use function, leading to building scrapping and even endangering people's lives. The use of waterproof materials in time to prevent water seepage and water leakage in buildings has been in use since the 1950s. [0003] Waterproof mortar is a kind of rigid waterproof material, which achieves the purpose of waterproof and impermeable by improving the compactness of the mortar and improving the crack resistance. It is mainly used for waterproofing projects that will not cause harmful cracks due to structural settlement, temperature and humidity changes, and vibration. There are three types of waterproof ...
