Waterproof protective material for deep well and preparation method of waterproof protective material

Abstract

The invention discloses a waterproof protective material for a deep well and a preparation method of the waterproof protective material. The waterproof protective material is prepared from water-based polymethyl silicone resin, deionized water, butyl stearate, an antioxidant, a water repellent agent, carboxymethylcellulose, polyacrylamide, fatty glyceride and a coloring agent. The water-based coating comprises the following components in parts by weight: 78-84 parts of water-based polymethyl silicone resin, 15-19 parts of deionized water, 3-5 parts of butyl stearate, 2-4 parts of an antioxidant, 2-4 parts of a water repellent agent, 1-3 parts of carboxymethylcellulose, 2-4 parts of polyacrylamide, 1-3 parts of fatty glyceride and 1-3 parts of a coloring agent. The hydrophobic agent formed by mixing the dimethyl silicone oil, the calcium palmitate and the microcrystalline wax is added, so that the waterproof performance of the material is greatly improved, the problem of underground water leakage is not easy to occur after long-term use, a protective layer is maintained, the problems of damp deformation, cracking and collapse of a deep well are avoided, and the use is safer.

Description

technical field [0001] The invention relates to the technical field of mine building materials, in particular to a waterproof protective material for deep wells and a preparation method thereof. Background technique [0002] Deep wells generally refer to mines that exceed a certain mining depth in mining engineering. The surrounding rock in the mining space is greatly deformed, and the rheological phenomenon is obvious. Different mining areas have different critical depths, mostly below 500 meters to 700 meters. At present, it is common to coat a layer of material on the inner wall of reinforced concrete structures in deep wells for protection during mining operations. [0003] However, ordinary deep well materials have poor waterproof performance. Long-term use is prone to groundwater leakage, which destroys the protective layer, causing the deep well to be deformed, cracked or even collapsed due to moisture. The lower material is seriously aged, cannot be used for a long ...

AI Technical Summary

Problems solved by technology

[0003]However, ordinary deep well materials have poor waterproof performance, and they are prone to groundwater leakage after long-term use, destroying the protective layer, causing the deep well to deform, crack and even collapse due to moisture , there is a certain safety risk, and the anti-oxidation performance is insufficient. The material is seriously aged in harsh environments, and cannot be used for a long time. The work reliability is poor and the shelf life is short. Weak, slow drying and curing, inconvenient to use, poor market competitiveness
