Abstract

The present invention aims to provide a pre-laid wet-laid waterproof roll material with a cross-linking reaction layer, including a main material layer, a bonding sealant layer and a cross-linking reaction layer, the bonding sealant layer is a petroleum asphalt layer, modified permanent asphalt layer or polymer pressure sensitive adhesive layer. The pre-paved wet-paved waterproof membrane according to the present invention can achieve better bonding effect with the concrete base surface after the cross-linking reaction layer is added, and is suitable for various asphalt or polymer pressure-sensitive adhesives as the main adhesive layer. The pre-laid wet-laid waterproof membrane of raw materials has a wide range of applications and outstanding technical effects. It solves the loss of the waterproof layer constructed by pre-laid wet-laid waterproof membrane due to the influence of environmental humidity and heat cycle, water vapor expansion, and grass-roots movement. The problem of sealing waterproof effect.

Description

technical field [0001] The invention relates to the field of sealing and waterproofing, in particular to a pre-laid wet-laid waterproof coiled material with a cross-linked reaction layer. Background technique [0002] At present, there are more and more waterproof and anti-seepage construction projects used in tunnels for transportation, subway basements, garage roofs, civil air defense projects, dams and culverts, and various pools. The materials used for waterproofing are mainly coatings and various Various sheets or coils, with the emergence of asphalt waterproof membranes or polymer sheets with fabric layers, because they can be produced industrially and are easy to use, they are more and more popular in building construction, especially It is the construction of the top floor of the building, the subway sky and the top surface of the embankment culvert. The side of the modified asphalt membrane with the adhesive is directly pasted to the concrete surface to achieve the ...
