Modified asphalt self-adhesive waterproof vapor barrier film based on molecular dispersion polymerization

Abstract

The invention discloses a modified asphalt self-adhesive waterproof vapor barrier film based on molecular dispersion polymerization, comprising a reel and an asphalt layer. The bottom end of the asphalt layer is bonded with an aluminum foil layer through asphalt, the bottom end of the aluminum foil layer is bonded with a polymer layer, a groove is formed in the polymer layer according to the proportion of 3:5-4:5, the groove is square, chamfers are formed in the four edges of the groove, and the chamfers are 30-50 degrees. according to the invention, the structure is scientific and reasonable,use is safe and convenient, through the aluminum foil layer, the fire resistance and the waterproofness can be conveniently improved, the types and arrangement of atoms, the types of substituent groups and end groups, the arrangement sequence of monomer units and the types and lengths of branched chains in the structure finger chain are realized through the polymer layer, the flexibility is thusenhanced, through up-and-down weaving of a woven layer, the toughness and the pulling effect of the whole vapor barrier film are improved, the service life of the vapor barrier film is prolonged, andthe contact effect between the vapor barrier film and the mounting position in the mounting process is improved through a sponge layer, so that the application range of the vapor barrier film is widened.

Description

technical field [0001] The invention relates to the technical field of vapor barrier membranes, in particular to a modified asphalt self-sticking waterproof vapor barrier membrane based on molecular discrete polymerization. Background technique [0002] The vapor barrier film is laid between the roof base and the insulation layer, which can enhance the air and water tightness of the building, slow down the discharge of water vapor in the concrete structure and indoor moisture to the insulation layer, prevent the formation of condensation, protect the insulation material and maintain the structure Excellent thermal performance, reduce building energy consumption, and provide moisture-proof and reflective properties. [0003] However, the waterproof and vapor barrier membranes currently on the market cannot improve their toughness and self-adhesiveness, which leads to complicated installation, poor sound absorption effect, and cannot improve their softness, resulting in that t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a modified asphalt self-adhesive waterproof and vapor-proof membrane based on molecular discrete polymerization, which can effectively solve the problem that the waterproof and vapor-proof membranes currently on the market cannot improve their toughness and are not easy to self-stick, resulting in complicated installation. And the sound absorption effect is poor, and its flexibility cannot be improved, which leads to the problem that it cannot be adjusted according to its installation environment during installation
