Problems solved by technology

The traditional construction method of modified asphalt waterproofing membrane is hot-melt construction. The asphalt on the surface of the membrane is melted by heating and then bonded to the roof. This construction method not only requires a lot of labor, but also pollutes the environment. It will make the joint between the coiled material and the roof or the coiled material not tightly bonded and sealed, resulting in roof leakage
Not only reduces the service life of the waterproof membrane, but also causes inconvenience to the user due to the replacement of the waterproof membrane

Abstract

The invention discloses a self-adhesion modified asphalt waterproof roll substrate and a preparation method and belongs to the field of waterproof rolls. The self-adhesion modified asphalt waterproof roll substrate comprises 80-100 parts of 70# asphalt, 5-10 parts of SBS modifier, 5-15 parts of epoxy resin, 0.1-3 parts of graphene, 5-15 parts of filler, 2-5 parts of plasticizer, 3-8 parts of softener, 1-5 parts of stabilizer, 1-3 parts of compatilizer, 1-5 parts of diluent and 1-5 parts of anti-stripping agent. The preparation method comprises the steps that firstly the epoxy resin and the graphene are mixed and modified, then the modified polymer and an SBS modified asphalt substrate are mixed uniformly, and the self-adhesion modified asphalt substrate is obtained. The self-adhesion modified asphalt substrate has higher cohesiveness and water resistance, the service life of the waterproof roll is prolonged greatly, and the self-adhesion modified asphalt waterproof roll substrate has a better application prospect.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a self-adhesive modified asphalt waterproof coiled material matrix and a preparation method. Background technique [0002] Waterproof materials are widely used in the engineering waterproofing of roofs and basements of various industrial and civil buildings, as well as engineering waterproofing of municipal and water conservancy facilities such as subways, tunnels, highway bridges, etc. The current waterproof membranes have poor resistance to damage and are prone to puncture Or tear phenomenon, need to spend manpower, material resources to repair, shorten the service life of waterproof material, cause the waste of resources and funds. [0003] The success of polymer modified bitumen waterproofing membrane waterproofing not only depends on its own quality, but also closely related to the bonding and sealing of the membrane and the roof. The traditional construction meth...
