Problems solved by technology

[0004] 1. It is well known that asphalt itself is a cold and brittle material with heat flow, so modified asphalt adhesives have poor high and low temperature resistance, which brings troubles to construction in summer and winter;
[0005] 2. The surface of the coil is not treated, and the feet are sticky, so workers cannot bind steel bars on the surface of the coil;
[0006] 3. There is no protective layer on the surface of the coiled material. If the construction period is delayed, under the action of ultraviolet rays and wind and rain, the bonding effect will be lost and the product will be scrapped;
[0007] 4. The bonding and peeling strength of modified asphalt adhesives is low

Embodiment 1

[0025] This embodiment provides a polymer pre-laid waterproof membrane. Such as figure 1 As shown, the polymer pre-paved waterproof membrane has a three-layer structure. Specifically, the polymer pre-laid waterproof roll includes a polymer substrate 1 , a polymer adhesive layer 2 covering the polymer substrate, and a protective layer 3 covering the polymer adhesive layer 2 .

[0026] The polymer substrate 1 is a waterproof sheet with a thickness of 1.0 mm made of high-density polyethylene pellets mixed at high and low speeds into a twin-screw extruder and shaped by a die. Control the temperature of each section of the twin-screw extruder, the temperature of the feeding section is room temperature, the compression section is 90-140°C, and the metering section is 180°C.

[0027] The formation method of polymer adhesive layer 2 is: according to the weight ratio of SBS rubber: naphthenic oil: hydrogenated petroleum resin=10:5:12, antioxidant 1010, ultraviolet stabilizer UVP and ...

Embodiment 2

[0031] This embodiment provides a polymer pre-laid waterproof membrane, the structure of which is the same as that of Embodiment 1. The difference is that:

[0032] The polymer substrate 1 is a waterproof sheet with a thickness of 1.0 mm made of polyethylene terephthalate mixed at high and low speeds into a twin-screw extruder and shaped by a die. Control the temperature of each section of the twin-screw extruder, the temperature of the feeding section is room temperature, the compression section is 90-140°C, and the metering section is 180°C.

[0033] The formation method of polymer adhesive layer 2 is: according to the weight ratio of polyisobutylene rubber: naphthenic oil: hydrogenated petroleum resin=10:5:12, antioxidant 1010, ultraviolet stabilizer UVP and calcium carbonate are according to 5% of total amount ‰, 7‰, and 10% are added to the feeder of the screw extruder to control the temperature of each section of the twin-screw extruder. The temperature of the feeding s...

Abstract

The invention relates to a macromolecule pre-laid waterproof coiled material which comprises a sheet-shaped macromolecule base material and a macromolecule adhesive layer formed on the macromolecule base material; and the macromolecule pre-laid waterproof coiled material is characterized by further comprising a protective layer coated on the macromolecule adhesive layer, wherein the macromolecule base material is high-density polyethylene, and polyethylene glycol terephthalate or ethylene-vinyl acetate copolymer; synthetic rubber is the main component of the macromolecule base material; and the material of the protective layer is silicon-containing unsaturated carboxylic acid modified butyl rubber which is prepared by the steps of grafting unsaturated carboxylic acid on butyl rubber molecule and then mixing with active silica. The macromolecule pre-laid waterproof coiled material has good high and low-temperature resistance and high adhesion peeling strength, and is easy to construct.

Description

technical field [0001] The invention relates to a polymer pre-laid waterproof coiled material used in the field of building waterproofing. Background technique [0002] With the acceleration of the urbanization process, cities are getting longer and taller, more and more crowded, and road traffic congestion is becoming more and more serious. Limited land resources have become difficult to accommodate more population and construction and development activities. Therefore, the development and utilization of underground space resources has become an inevitable choice for the current and future development of many cities. At present, the utilization of underground space has involved: underground commercial facilities, underground parking stations, underground reservoirs, warehouses, subways, underground streets, underground passages and so on. However, the impact of water channeling, leakage and settlement in underground waterproofing projects is still a major problem that plag...
