Abstract

The invention provides a quick-setting plugging material which comprises the following components in parts by weight: 72-75 parts of sulphoaluminate cement, 15-25 parts of Portland cement, 5-8 parts of carborundum, 5-8 parts of quartz sand, 1-2 parts of cellulose, 1-2 parts of silica gel powder and 0.5-1 part of a water reducing agent, and 0.5-1 part of calcium stearate. The invention also provides a preparation method of the plugging material, and the provided plugging material can be constructed with water, has the effects of rapid condensation, high strength, water resistance, impermeability and the like, and can be suitable for plugging and water stopping of projects such as various underground buildings or structures, cable channels, pools, toilets and bathrooms, kitchens, civil air defense caverns, subways, tunnels and the like; and emergency repair of underground pipelines, tap water pipelines, dams and equipment foundations.

Description

technical field [0001] The invention relates to the technical field of water leakage and plugging prevention materials, in particular to a quick-setting type leakage plugging material and a preparation method thereof. Background technique [0002] Water tightness is a plugging material used for plugging cracks, wall holes, etc. Chinese patent CN106517969A discloses a quick-setting water tightness, which has the characteristics of short setting time and high compressive strength, and can also be plugged with water pressure. However, in the actual application process, when plugging some larger cracks (length greater than 20cm, width greater than 5cm), there may be collapse in the middle position after solidification, which eventually leads to water seepage at the plugging. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies in the prior art, the present invention provides a quick-setting leakage plugging material and a preparation method thereof, which solves the p...
