Plastic reactive butyl rubber self-adhesion waterproof coil for tunnel metro

Abstract

The invention discloses a plastic reactive butyl rubber self-adhesion waterproof coil for a tunnel metro. The plastic reactive butyl rubber self-adhesion waterproof coil for the tunnel metro comprises plastic waterproof coil, a butyl rubber self-adhesion layer and a butyl rubber anti-adhesion layer which are adjacent to each other from up to down sequentially. The butyl rubber self-adhesion layer comprises butyl rubber, ethylene vinyl acetate copolymer, active silica, gamma-aminopropyltriethoxysilane and the like. According to the plastic reactive butyl rubber self-adhesion waterproof coil for the tunnel metro, the plastic waterproof coil and the butyl rubber self-adhesion layer are compounded into a functional waterproof material, the waterproof coil is superstrong in compression sensitivity and self-healing, the plastic reactive butyl rubber self-adhesion waterproof coil for the tunnel metro is capable of forming effect of being solidified and fully-adhered with concrete, and saving cost needed in later stage check and repair, and is widely used in a waterproof layer of metro tunnel construction.

Description

technical field [0001] The invention relates to building waterproof materials, in particular to a plastic reactive butyl rubber self-adhesive waterproof coiled material for tunnel subways. Background technique [0002] With the sustained and rapid development of our country's national economy, urban construction is also increasingly prosperous, causing the urban population to continue to expand, resulting in increasingly serious tension in urban traffic. Due to the shortage of urban ground land resources, urban traffic can only develop in underground space and in the air, and the construction of underground railways is developing rapidly. However, most of the large cities in our country are located in coastal areas or along rivers, and the groundwater level is high. If there are no reliable waterproof measures, groundwater will invade, endangering the operation of subways and affecting the service life of tunnels and subways. [0003] Plastic waterproof membrane has the adv...

Problems solved by technology

However, most of the large cities in our country are located in coastal areas or along rivers, and the groundwater level is high. If there are no reliable waterproof measures, groundwater will invade, endangering the operation of subways and affecting the service life of tunnels and subways.

[0003] Plastic waterproof membrane has the advantages of strong toughness, anti-freezing, high temperature resistance, long service life, and good waterproof effect. Paste the waterproof layer directly with the structural concrete, so that the waterproof layer and the main structure are separated from the main structure, and it is easy to leak water

It is difficult and expensive to control leakage, which will reduce the durability of underground buildings, deteriorate the operating environment in the tunnel, and affect the normal traffic of the subway tunnel
