AI Technical Summary

Problems solved by technology

When the binding time of steel bars on the adhesive layer exceeds its own weatherproof sealing safety (7 to 28 days), it will cause the adhesive sealing failure, and the open water under the waterproof layer will enter in large quantities through the defects or damaged parts of the waterproof itself. Between the waterproof layer and the concrete structure layer, it will enter the interior of the structure at the structural cracks, resulting in engineering leakage

Embodiment 1

[0036] Such as figure 1 As shown, a fiber-reinforced TSR polyethylene tire modified asphalt waterproof membrane includes a fiber reinforced layer 1, an upper adhesive layer 2, a modified polyethylene tire base layer 3, a lower adhesive layer 4 and Isolation film5.

[0037] Wherein, the fiber-reinforced layer 1 is one of non-woven fabrics made of polyester, polypropylene, polyester fiber, nylon or polypropylene fiber.

[0038] Wherein, the upper adhesive layer 2 and the lower adhesive layer 4 are both chemical root puncture resistant colloidal layers.

[0039] Wherein, the preparation method of the chemical root-resistant puncture-resistant colloidal layer is as follows:

[0040] S1: ratio of asphalt and oil;

[0041] S2: Add polymer modifier SBS, butyl rubber IIR and natural rubber CR, keep the temperature at 180-190 degrees Celsius, and stir at 45Hz for 1 hour;

[0042] S3: Grinding with a colloid mill at a grinding temperature of 180-190 degrees Celsius;

[0043] S4: ke...

Embodiment 2

[0047] The invention also discloses a construction method of fiber-reinforced TSR polyethylene tire modified asphalt waterproofing membrane, which includes the following steps:

[0048] P1: Concrete cushion construction on the floor of the underground project, leveled and calendered once; the thickness of the concrete cushion is 100-150mm.

[0049] P2: Hot-melt construction: After the surface of the cushion concrete is flat, dry, and free of open water, the hot-melt fiber-reinforced TSR polyethylene tire modified asphalt waterproofing membrane makes the fiber-reinforced TSR polyethylene tire modified asphalt waterproofing membrane The material is bonded to the cushion concrete and the cushion concrete is sealed so that the fiber reinforced layer faces upward;

[0050] P3: Pre-paving construction: After 12-24 hours, on the surface of the waterproof layer, on the surface of the completed waterproof layer, the reinforcement of the base plate structure is plated on the fiber reinf...

Embodiment 3

[0054] In TSR, T is a hot-melt type, S is a self-adhesive type, and R is a polymer-modified asphalt root-resistant waterproof membrane.

Abstract

The invention discloses a fiber reinforced TSR polyethylene tire modified asphalt waterproofing coil which comprises a fiber reinforcing layer, an upper bonding layer, a modified polyethylene tire base layer, a lower bonding layer and an isolating membrane which are sequentially connected to each other. The invention further discloses a construction method of the fiber-reinforced TSR polyethylenetire modified asphalt waterproofing coil. The construction method comprises the following steps of P1, construction of a concrete underlayer of an underground engineering floor, leveling and performing of calendaring once, P2, hot melt construction and P3, pre-paving construction. According to the fiber reinforced TSR polyethylene tire modified asphalt waterproofing coil and the construction method, the hot melt and pre-paving construction methods are combined in the construction of the waterproofing coil, the waterproofing structure is simple in layer, the double guarantee of waterproofing safety is realized, and the probability of water leakage is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of underground engineering waterproofing, in particular to a fiber-reinforced TSR polyethylene tire modified asphalt waterproofing membrane and a construction method thereof. Background technique [0002] In recent years, waterproof membranes have been widely used in construction projects, among which modified asphalt waterproof membranes are widely used, and modified asphalt polyethylene tire waterproof membranes have good impermeability and corrosion resistance, and are easy to break. High elongation, tear resistance and other characteristics, the product is widely used in roofing and underground waterproofing and moisture-proofing projects, and has become one of the main products of modified asphalt waterproofing membranes in China. At present, the traditional polyethylene tire root-resistant puncture-resistant modified bitumen waterproofing membrane produced in China has poor thermal dimensional stabilit...
