Problems solved by technology

However, after the cross-linking agent is mixed with asphalt, most of the cross-linking agent is inside the waterproof membrane, and less can be in contact with the concrete interface. The amount of addition and the adhesion effect are not optimal.

Abstract

The objective of the invention is to provide a pre-paving wet-paving waterproof coiled material with a crosslinking reaction layer. The coiled material comprises a main material layer, a bonding and sealing adhesive layer and the crosslinking reaction layer. The bonding and sealing adhesive layer is a petroleum asphalt layer, a modified asphalt layer or a polymer pressure-sensitive adhesive layer. By adding the crosslinking reaction layer to the coiled material, better bonding effects with concrete bases can be achieved. The crosslinking reaction layer is suitable for various pre-paving wet-paving waterproof coiled materials adopting various kinds of asphalt or polymer pressure-sensitive adhesives as main raw materials of adhesive layers. The coiled material is wide in application range and excellent in technical effects, and overcomes a problem that sealing and water proofing effects of waterproof layers formed by pre-paving wet-paving waterproof coiled materials become invalid due to influences of environment thermal humidity cycling, water vapor expansion, base movement, and the like.

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 ...
