Abstract

The invention provides a creeping non-cured rubber asphalt waterproof roll material, aiming to solve the problems of poor water seepage resistance, poor tensile strength, poor weather resistance and poor basal plane binding capacity for cast-in-place concrete in the conventional self-adhered waterproof roll material. The creeping non-cured rubber asphalt waterproof roll material comprises a polyethylene membrane and an asphalt adhesive layer with which the polyethylene membrane is coated, wherein the asphalt adhesive layer is prepared from the following components of base asphalt, hot melt adhesive, rubber modifying agent, viscosity-enhancing rubber and modified padding; the modified padding is grafted fumed silica. Meanwhile, the invention further discloses a preparation method for the creeping non-cured rubber asphalt waterproof roll material. The creeping non-cured rubber asphalt waterproof roll material provided by the invention has high water seepage resistance, high tensile strength, high weather resistance and high basal plane binding capacity for the cast-in-place concrete.

Description

Technical field [0001] The invention belongs to the technical field of building waterproof materials, and relates to a creep type non-curing rubber asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Self-adhesive waterproof membrane is a kind of self-adhesive rubber asphalt prepared with synthetic rubber such as SBS, tackifier and high-quality road petroleum asphalt as the base material. The polymer film is used as the upper surface material, and the peelable silicon-coated isolation film or Silicone-coated isolation paper is a waterproof material made of anti-stick isolation material on the lower surface. [0003] Existing self-adhesive waterproof membranes have many advantages of underground waterproofing when used, and have incomparable deformation resistance and self-healing properties of polyester tires or glass fiber tires, but their water permeability, The tensile strength and weather resistance are poor. In recent years, it ha...
