Butyl rubber reactive bonding layer used for pre-paving reactive-bonding waterproofing coiled material, preparation method thereof, and the pre-paving reactive-bonding waterproofing coiled material

Abstract

The invention discloses a butyl rubber reactive bonding layer used for a pre-paving reactive-bonding waterproofing coiled material, a preparation method thereof, and the pre-paving reactive-bonding waterproofing coiled material, and relates to the technical field of high-molecular pre-pavement materials. The butyl rubber reactive bonding layer is mainly produced from: 100 parts of raw rubber, 9.5-15.5 parts of a linear tackifying resin containing terminal hydroxyl group structure, and 12.5-19.5 parts of active filler comprising active silicon dioxide and aluminum oxide. The reactive bonding layer solves the defects that a bonding layer of a waterproofing coiled material in the prior art is liable to flow, deform and wrinkle when being heated, is brittle at low temperature, is free of sticking feet only if a single anti-sticking layer or insulation layer exists, and is poor in stripping strength with post-poured concreted. The butyl rubber reactive bonding layer can form permanent chemical bonds with concrete, so that a real skin-type water-proofing structure is formed between the pre-paved high-molecular waterproofing coiled material and the concrete, and the bonding layer is freeof sticking feet and allows people to walk thereon without coverage by sand and coating layers. In addition, the reactive bonding layer has good low temperature resistance and thermal stability.

Description

technical field [0001] The invention relates to the technical field of polymer pre-laying materials, in particular to a butyl adhesive reactive adhesive layer used for pre-laying reactive adhesive waterproof membranes, a preparation method thereof, and pre-layed reactive adhesive waterproof membranes. Background technique [0002] Building waterproofing is a measure taken to resist external rainwater and groundwater leakage in projects such as walls, roofs, tunnels, highways, underground garages, and residential buildings. It is the first barrier for the entire project and buildings. It plays a vital role. [0003] The polymer pre-paved reactive adhesive waterproofing membrane is suitable for waterproofing basements, reservoirs, roofs, interior and exterior walls of various civil and industrial buildings. In addition, it can also be used for anti-seepage and anti-leakage of various sewage treatment plants, swimming pools, etc., and waterproof and anti-seepage of various und...

AI Technical Summary

Problems solved by technology

[0004] At this stage, the polymer waterproof membrane adhesive layer is commonly used in underground buildings, most of which are hot-melt pressure-sensitive adhesive systems. Anti-adhesive layer or isolation layer, in order to not stick to the feet, easy to construct and form a bond with the cured concrete; the peel strength between the adhesive layer and the post-cast concrete is low; there are also a small part of the reactive adhesive layer that is black butyl Adhesive layer, it is not easy to identify the leakage point, which limits the construction application field of pre-laid reactive adhesive membrane
