Coal mine underground coal bed waterproof paint

Abstract

The invention provides a coal mine underground waterproof paint, which is characterized by comprising the following components in part by weight: 13 to 27 parts of re-dispersible latex powder, 30 to 40 parts of cement, 35 to 40 parts of quartz sand, 5 to 10 parts of graphite powder, 5 to 10 parts of fly ash, 4 to 6 parts of vermiculite powder, 4 to 6 parts of expanded perlite powder, 4 to 6 parts of aluminum hydroxide, 2 to 4 parts of magnesium hydroxide, 0.003 to 0.024 part of air entraining agent, and 0.02 to 0.09 part of water reducing agent. Compared with other waterproof paint, the coal mine underground waterproof paint has the advantages of good waterproofing quality, flame resistance, antistatic property, elasticity, good cohesive property with coal, light weight, environmental protection, nontoxicity, easy construction and the like, and is suitable for coal mine underground waterproofing.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to an underground coal seam waterproof coating in a coal mine. Background technique [0002] During the construction and production of the mine, surface water and groundwater enter the mine through various channels, resulting in damp coal walls and common water leakage, which affects underground production. Spraying waterproof paint on the seepage coal wall can effectively prevent the seepage of water. [0003] Because fires are prone to occur underground in coal mines, the coal wall is uneven and slowly deformed, and the roadway contains gas gas and other environmental conditions require coal mine underground waterproof coatings not only to have excellent waterproof performance, but also to be flame retardant, antistatic, and adhere to wet coal. It has good binding properties, certain deformability, environmental protection and non-toxicity, and is easy for underground construction. [000...

AI Technical Summary

Problems solved by technology

These waterproof coatings are used for building waterproof coatings, have coating film good elasticity, acid and alkali resistance, anti-aging, have good water resistance, possess thermal insulation again, but there are following deficiencies in being used for coal mine underground waterproofing: 1) resistance Poor flammability, some products are extremely flammable; 2) Poor antistatic performance; 3) Poor water resistance, high water absorption rate, obvious softening after long-term immersion in water, water swelling, and strength decline; 4) Large polymer consumption and high cost

The above shortcomings make general JS coatings unusable in coal mines
