Sticking modified asphalt waterproof coiled material and adhesive, as well as preparation method and application thereof

Abstract

The invention relates to the field of waterproofing materials and waterproofing work, providing a bonded modified asphalt waterproof roll material, matched bonding adhesive, a preparation method and the assorted application thereof in the waterproofing work. The bonded modified asphalt waterproof roll of the invention adopts a basic tyre as a frame, a modified asphalt layer and a surface layer are sequentially stuck to the surface of the basic tyre, one face of the surface layer is polyester non-woven fabric, and the other face is polyester non-woven fabric, polyethylene film, aluminum foil, color sand or cleaving stone. The bonding adhesive of the invention comprises the following components: 60 to 120 portions of asphalt, 3 to 30 portions of affinity agents, 2 to 20 portions of phenolic resin and 30 to 180 portions of filling agents. During the application of the invention on the waterproofing work, one to three layers of bonding adhesive and the bonded modified asphalt waterproof roll are laid and stuck to a basic layer as a waterproof layer. The invention has the advantages of absence of thermal construction, effective blockage of direct leakage points of the basic layer and complicated parts of a building, strong binding force, normal construction under low temperature environment, etc.

Description

technical field [0001] The invention relates to the field of waterproof materials and waterproof engineering, in particular to a modified asphalt waterproof coiled material and an adhesive, a preparation method thereof and its application in waterproof engineering of highway bridge decks, subway projects, railway bridges and culverts, basements and roofs. Background technique [0002] In the existing technology, waterproofing projects mostly use modified asphalt waterproofing membranes for waterproofing. This waterproofing membrane uses the base as the skeleton material, such as polyester base, glass fiber base, polyethylene base, composite base, etc. After the modified asphalt is adhered on both sides of the tire base, polyethylene film (also known as PE film) is adhered, or polyethylene film is adhered to one side of the modified asphalt, and colored sand, shale or aluminum foil is adhered to the other side of. The PE film plays the role of isolation and protection when t...

AI Technical Summary

Problems solved by technology

[0005] 3) The complex parts of the building (also the parts that need key waterproofing) are difficult to construct;

[0006] 4) The direct leakage points of the base, such as cracks, sand holes and capillary pores on the concrete base, cannot be effectively sealed and waterproofed;

[0007] 5) The seam between the coiled material and the coiled material is prone to water leakage;

[0008] 6) The adhesion between the coiled material and the base layer is not strong, resulting in a leakage point causing leakage everywhere, and it is difficult to find the leakage point when the leakage is found

[0010] 1) The direct leakage point of the base layer and the complex parts of the building cannot be effectively sealed and waterproofed;

[0011] 2) The isolation film needs to be removed during construction, which increases the cost of coiled materials and construction, and generates construction waste and pollutes the environment;

[0012] 3) The construction is greatly affected by the ambient temperature: when the ambient temperature is below 15°C, the adhesive force will drop significantly; below 0°C, it cannot be constructed in the form of cold paste, and it does not have true self-adhesiveness;

[0013] 4) The cohesive force of the coiled material is insufficient, and the facade construction needs to be fixed with cement nails, which will cause damage to the coiled material

[0014] Therefore, the waterproof effect of the above two modified asphalt waterproofing membranes is not satisfactory.
