Polyolefin composite modified asphalt wet-laid waterproof roll and production method thereof

Abstract

The invention discloses a polyolefin composite modified asphalt wet-laid waterproof roll and a production method thereof. The polyolefin composite modified asphalt wet-laid waterproof roll comprises a modified asphalt binding layer, a binding isolation membrane protecting layer and a polyolefin thermoplastic elastomer material layer which can achieve a chemical crosslinking reaction and a physical mortise-and-tenon collaborative binding action in cooperation with concrete; and the interlayer structure is as follows: the first layer is the polyolefin thermoplastic elastomer material layer, the middle layer is the modified asphalt binding layer, and the lower layer is the isolation membrane protecting layer, and the layers are subjected to thermocompression binding in the production process. The waterproof performance of the waterproof roll is excellent; and the waterproof roll is wriggled and seeped into capillary bores in cement gel and concrete in cement and concrete setting processes by using modified asphalt with reactivity, and has a chemical crosslinking reaction at a contact interface, so that a basal plane reaction layer which is large in binding force, irreversible in binding, concurrently pliable and hard in binding, lasting in binding is formed, thereby achieving a closely and firmly combined and irreversible binding effect as closely linked as flesh and blood.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a reaction bonding polyolefin composite waterproof coiled material capable of chemical crosslinking reaction with concrete. 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, dam culverts, various pools, and building roofs. The materials used for waterproofing are mainly Coatings and various sheets or coils, with the emergence of asphalt waterproof membranes or polymer sheets with fabric layers, because they can be produced in factories and are easy to use, they are more and more popular in building construction. It is favored by people, especially in 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 ...

Problems solved by technology

[0006] However, the inventors have found that the above patents and the waterproof coiled materials seen on the market are mainly modified asphalt waterproof coiled materials and polymer sheets, and their construction methods are mostly hot-pressed construction or oily mooring paste, oily base Bonded with oil and polymer glue, there are high energy consumption, danger, high environmental pollution, and wet base surface construction bonding is not firm; waterproofing bonded with polyvinyl alcohol latex cement adhesive and other polymer latex cement adhesive Rolled materials, which are bonded to the base surface through physical adsorption and certain mortise and tenon effects between the cement slurry and the base surface, are easily affected by environmental humidity and heat cycles, water vapor expansion, and base movement Decreased cohesive force, resulting in the process of desorption and mortise and tenon removal, and loses the permanent sealing and waterproof effect
