High-tenacity waterproof coiled material and preparation method

Abstract

The invention discloses a high-toughness waterproof coiled material and a preparation method thereof, belonging to the field of waterproof coiled materials. The waterproof coiled material includes: a substrate layer, the upper and lower surfaces of the substrate layer are respectively provided with self-adhesive waterproof layers, and the surfaces of the self-adhesive waterproof layers are respectively provided with isolation protection layers. Wherein, the base material layer is an alkaline glass fiber felt layer, the self-adhesive waterproof layer is a polymer modified asphalt, and the isolation protection layer is a PE film. The preparation steps include: (1) preparation of graphene/natural rubber nanocomposite material; (2) preparation of polymer modified asphalt; (3) preparation of waterproof coiled material. The waterproof coiled material of the present invention not only has good waterproof and anti-corrosion effects, but also greatly improves the toughness of the waterproof coiled material, and the existence of graphene makes the waterproof coiled material have better environmental stability, greatly extending the waterproof coiled material. service life and has a good application prospect.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a high-toughness waterproof coiled material and a preparation method thereof. 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] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. At present, the commonl...

AI Technical Summary

Problems solved by technology

In the application places with high fire protection level requirements, the required waterproof membrane is required to have certain fire and flame retardant properties, while the fire and flame retardant properties of ordinary polymer modified asphalt are poor and cannot meet the requirements for use.

[0004] The existing asphalt waterproofing membrane has low tensile strength, low elongation, poor temperature stability, and is easily affected by the weather; therefore, its waterproof performance is poor, weather resistance is poor, and its service life is short

At present, one of the better quality waterproof membranes at home and abroad is the polymer waterproof membrane—CPE (chlorinated polyethylene), which is a saturated polymer material widely used; the CPE waterproof membrane has excellent Weather resistance, ozone resistance, chemical resistance, aging resistance, oil resistance, flame retardancy and coloring performance, but the CPE waterproof membrane is made of CPE, and the deformation resistance of the membrane is poor, and the temperature change is easy to cause damage to the membrane. Shrinkage and expansion can easily cause the membrane to break and form micropores, which affects the waterproof performance and strength of the waterproof membrane
