Plugging permeability-preventing agent

Abstract

The invention discloses a plugging permeability-preventing agent, which is prepared from the following raw materials in percentage by weight: 25% of caustic soda, 6% of sodium methyl silicate, 10% of quartz powder, 10% of gypsum and 50% of water. The preparation method of the plugging permeability-preventing agent comprises the following steps: firstly, adding water into the caustic soda for uniformly mixing and stirring, slowly adding the sodium methyl silicate, the quartz powder and the gypsum in the stirring process for uniformly stirring, and filtering waste residues to obtain a finished product. The plugging permeability-preventing agent of the invention is suitable for various concrete buildings such as roofs, oil depots, water towers, water channels, washing rooms and the like, canenable the gaps of cement mortar concrete to be compact, has the effects of preventing water and permeability, and simultaneously can improve the compressive strength and the tensile strength of the cement mortar concrete. Because the plugging permeability-preventing agent is ventilated, layer surfaces can not be expanded, deformed, weathered and peeled off and can be bonded together again to perform the action of plugging.

Description

technical field [0001] The invention relates to waterproof materials, in particular to a leak-stopping and anti-seepage agent for concrete buildings. Background technique [0002] Existing waterproofing agents, such as ointment and asphalt, achieve the effect of waterproofing and plugging by blocking the holes of masonry and concrete structural materials, but the anti-seepage pressure is low and the cohesive force is small, and the long-term anti-seepage and moisture-proof plugging effect is still not achieved . Contents of the invention [0003] The object of the present invention is to provide a high-strength and long-durability plugging and anti-seepage agent for the shortage of existing leak-stopping and anti-seepage agents. [0004] In order to achieve the above object, the plugging and anti-seepage agent of the present invention is made from the raw materials of the following weight percentages: [0005] Caustic soda 25%, sodium methyl silicate 6%, quartz powder 10...
