Abstract

The present invention provides hole-sealing slurry and a preparation method thereof, and relates to the field of hole-sealing materials, and the hole-sealing slurry comprises the following raw materials by weight: 330-400 parts of cement, 590-670 parts of sand, 3-10 parts of a water reducer, 40-70 parts of an expanding agent, 0.2-0.5 part of aluminum powder, 3-7 parts of an air-entraining agent and 0.3-0.7 part of cellulose. The preparation method of the hole-sealing slurry is as follows: adding the raw materials into a raw material mixer to mix evenly. The hole-sealing material is fast in solidification speed, high in compressive strength and large in volume expansion rate, after 28 days, the strength is up to 20MPa or more, the volume expansion reaches 2.3%, and the preparation process is simple.

Description

technical field [0001] The invention relates to the field of sealing materials, in particular to a sealing slurry and a preparation method thereof. Background technique [0002] At present, the commonly used polyurethane sealing material has a large amount of sealing due to its small expansion rate; when the expansion rate of polyurethane is increased, its strength decreases and the sealing effect is poor; at the same time, the cost of polyurethane sealing material is relatively high, and the price is 20,000 yuan. / ton or so. Contents of the invention [0003] The invention proposes a hole-sealing slurry and a preparation method thereof, which solves the problem that the expansion rate and strength of the existing hole-sealing materials cannot be improved simultaneously. [0004] Technical scheme of the present invention is realized like this: [0005] A kind of hole sealing slurry, its raw material comprises by weight: 330-400 parts of cement, 590-670 parts of sand, 3-...
