Reactive butyl rubber self-adhesive layer for waterproof roll and processing technology thereof

Abstract

The invention discloses a reactive butyl rubber self-adhesive layer for a waterproof roll and a processing technology thereof. The reactive butyl rubber self-adhesive layer comprises the following components in parts by weight: 20 parts of butyl rubber, 1.0-4.2 parts of ethylene vinyl acetate copolymer, 16.5-20.5 parts of tackifying resin, 18.4-24.0 parts of tackifier, 12-18 parts of carbon black, 9-14 parts of light calcium carbonate, 8.0 parts of functional aid, 1.8 parts of vulcanizing agent, 0.8 part of anti-aging agent and 0.5 part of coupling agent. The butyl rubber self-adhesive layer is prepared by mixing, kneading and extruding forming. Due to the mode, the invention provides a reactive butyl rubber self-adhesive layer for a waterproof roll and a processing technology thereof, the butyl rubber self-adhesive layer can be chemically reacted with cast-in-place concrete to form a whole, a permanent waterproof layer is formed and has the self-healing performance, the waterproof layer and various high polymer waterproof rolls can be compounded to form a functional waterproof material, and the reactive butyl rubber self-adhesive layer is suitable for various underground waterproof engineering.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a reactive butyl rubber self-adhesive layer for waterproof coiled materials and its processing technology. Background technique [0002] Buildings are structures built by people using materials such as soil, stone, wood, and steel. In construction projects, people are most concerned about the quality and safety of houses, and building waterproofing is one of the important components of building quality and safety. Building waterproofing is a measure taken on building materials and structures to prevent water from penetrating certain parts of a building. It is generally used in construction projects such as roofs, underground buildings, and underground parts of buildings. Among them, polymer waterproof materials are mainly It can block the passage of water and increase the anti-leakage ability as one of the important waterproof methods of buildings. [0003] Since the underground...

AI Technical Summary

Problems solved by technology

[0003] Since the underground part of the building and the bottom plate and side wall of the underground building have no construction space, generally only the method of pasting the waterproof membrane and the concrete cushion can be used for underground waterproofing, but this waterproof method prevents the waterproof membrane from being directly connected to the underground concrete. The main structure is bonded, causing the waterproof layer to be separated from the main structure

Compared with the whole building with multiple processes and many days of construction, the waterproof membrane is only a very thin film layer. In actual construction, the deformation and settlement of the floor cushion, the harsh construction environmental conditions, the quality control of waterproof construction, Many problems such as cross construction may damage the waterproof layer. Even if the highest waterproof level and perfect construction plan are adopted, it is still impossible to ensure that these factors are fully controlled within the expected range

Once the waterproof layer is damaged, groundwater will infiltrate, and even water will emerge from the concrete two to three meters thick. However, the exact location of the leakage cannot be found, which makes maintenance difficult and seriously affects the service life of the building.
