Antiflaming waste rubber powder modified asphalt wet-paving waterproof coiled material and production method thereof

Abstract

The invention discloses an antiflaming waste rubber powder modified asphalt wet-paving waterproof coiled material and a production method thereof. The antiflaming waste rubber powder modified asphalt wet-paving waterproof coiled material comprises an antiflaming modified asphalt sticky layer, an isolation film protection layer and an antiflaming main body material layer which can generate chemical crosslinking reaction and physical mortise-tenon coordinative sticking action together with concrete. According to the interlayer structure of the coiled material, the surface layer is a protection film; the second layer and the fourth layer are waste rubber powder modified asphalt adhesive layers; the third layer is a main body layer; and all the layers are adhered through hot pressing during production. The waterproof coiled material has high waterproof performance; the modified asphalt with reaction activity penetrates into cement gel and concrete capillary holes in a creepage manner when cement and concrete are solidified; and the chemical crosslinking reaction happens at contact interfaces to form a base surface reaction layer; and by addition of the waste rubber powder and the antiflaming agent, the coiled material has a good antiflaming effect.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a reaction-adhesive polyolefin composite waterproof coiled material which is added with flame-retardant waste rubber powder and can undergo a chemical cross-linking 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 culv...

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 The bonding force decreases, resulting in the process of desorption and tenon removal, and loses the permanent sealing and waterproof effect. At present, there are few flame-retardant waterproof membranes. Once the waterproof membrane is used for the roof, the asphalt on the roof will be ignited first when a fire occurs. , increasing the hidden dangers of the building
