Problems solved by technology

At present, most quick-setting water-tight types on the market have a condensing time of about 3 minutes. The condensing time is long, and the strength after condensing is small. The effect of high-pressure water leakage is not particularly ideal.

preparation example Construction

[0025] The invention relates to a quick-setting water-proof and a preparation method thereof. The quick-setting water-proof comprises: 60-70 parts of fast-hardening sulfoaluminate cement, 42.5 parts of ordinary silicon Salt cement 18-27 parts, quartz sand 7-12 parts, calcium chloride 0.7-0.9 parts, lithium chloride 0.6-1.0 parts, water reducing agent 0.14-0.18 parts, cellulose 0.14-0.18 parts, rubber powder 0.19- 0.23 parts, 0.06-0.1 parts of calcium stearate.

[0026] The specific preparation method of the quick-setting type water leak provided by the invention comprises the following steps:

[0027] Step 1. Add half of the total amount of quick-hardening sulfoaluminate cement and 42.5 ordinary Portland cement into the mixing tank and stir for 10-20 minutes;

[0028] Step 2. Add calcium chloride, lithium chloride, water reducer, cellulose, rubber powder, and calcium stearate to the mixing tank in sequence and continue stirring for 10-20 minutes;

[0029] Step 3: Add the coa...

Embodiment 1

[0032] The quick-setting type watertight in the present embodiment comprises: 69.35 parts of fast-hardening sulfoaluminate cement, 20.3 parts of 42.5 ordinary Portland cement, 8.1 parts of quartz sand, 0.82 part of calcium chloride, 0.82 part of lithium chloride, 0.16 parts of water, 0.16 parts of cellulose, 0.21 parts of rubber powder, and 0.08 parts of calcium stearate.

[0033] Preparation method: First put half of the total amount of quick-hardening sulfoaluminate cement and 42.5 ordinary Portland cement, that is, 45.4 parts, into the mixing tank and stir for 15 minutes, then add calcium chloride, lithium chloride, water reducer, Cellulose, rubber powder, and calcium stearate were added to the mixing tank in turn and stirred for 15 minutes, and finally the quartz sand, the remaining rapid hardening sulfoaluminate cement and 42.5 ordinary Portland cement were added to the mixing tank and stirred for 20 minutes.

Embodiment 2

[0035] The quick-setting type watertight in the present embodiment comprises: 64.35 parts of fast-hardening sulfoaluminate cement, 25.3 parts of 42.5 ordinary Portland cement, 8.1 parts of quartz sand, 0.82 part of calcium chloride, 0.82 part of lithium chloride, 0.16 parts of water, 0.16 parts of cellulose, 0.21 parts of rubber powder, and 0.08 parts of calcium stearate.

[0036] Preparation method: First add half of the total amount of quick-hardening sulfoaluminate cement and 42.5 ordinary Portland cement into the mixing tank and stir for 15 minutes, then add calcium chloride, lithium chloride, water reducer, cellulose, rubber powder , calcium stearate were added to the mixing tank in turn and stirred for 15 minutes, and finally the quartz sand, the remaining rapid hardening sulfoaluminate cement and 42.5 ordinary Portland cement were added to the mixing tank and stirred for 20 minutes.

Abstract

The invention relates to a rapid solidifying type water leakage plugging material and a preparation method thereof. The rapid solidifying type water leakage plugging material is prepared from 60-70 parts of rapid hardening sulphoaluminate cement, 18-27 parts of 42.5 ordinary Portland cement, 7-12 parts of quartz sand, 0.7-0.9 part of calcium chloride, 0.6-1.0 part of lithium chloride, 0.14-0.22 part of a water reducing agent, 0.14-0.18 part of cellulose, 0.19-0.23 part of rubber powder and 0.06-0.1 part of calcium stearate. The rapid solidifying type water leakage plugging material can be solidified to generate heat in 1 minute and achieve the compressive strength of 10 MPa or above in 5 minutes, has the leakage plugging and water preventing functions and can be widely applied to rapid water plugging, rush repair and the like in engineering such as pools, houses, underground and tunnels, achieve in-water under-pressure leakage plugging and be applied to treatment on cement pipe and cast iron pipe cracks and joints.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a quick-setting watertight and a preparation method thereof. Background technique [0002] In industrial production or daily life, affected by factors such as building settlement, deformation, and aging, it is inevitable that there will be leakage in building facilities or confined spaces, which affects industrial production and daily life. At present, most quick-setting watertight water-tight products on the market have a setting time of about 3 minutes. The setting time is long, and the strength after setting is small. The effect of high-pressure water leakage is not particularly ideal. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and to provide a quick-setting water-proof and a preparation method thereof. [0004] In order to achieve the above object, according to one aspect of the pres...
