Ethylene propylene diene monomer waterproof roll

Abstract

The invention relates to the technical field of ethylene propylene diene monomer rubber, in particular to an ethylene propylene diene monomer waterproof roll which comprises a waterproof roll body, mounting rings, T-shaped rods, arc grooves, springs, magnetic blocks, an arc-shaped clamping plate, fastening bolts, nuts, clamping blocks, bearings, a first rubber layer, a waterproof layer, a butyl rubber layer, a silicon rubber layer, a second rubber layer and a reel. The T-shaped rods move to drive the arc-shaped clamping plate to move to be separated from the magnetic blocks; the arc-shaped clamping plate move to be attached to the waterproof roll body and then one end of the waterproof roll body is attached to the waterproof roll body and the loosening phenomenon of the waterproof roll body is avoided; the design of the waterproof layer improves the waterproof effect of the waterproof roll body; the design of the butyl rubber layer improves the waterproof effect and the tensile strength of the waterproof roll body, the design of the silicone rubber layer improves the high-temperature-resistant effect of the roll body, and the design of the first rubber layer and the second rubber layer has resistance to polar solutions and chemicals and is low in water absorption and has a good insulation characteristic.

Description

technical field [0001] The invention relates to the technical field of EPDM rubber, in particular to an EPDM waterproof membrane. Background technique [0002] EPDM is a terpolymer of ethylene, propylene and non-conjugated dienes. Diene has a special structure, only one of the two bonds can be copolymerized, and the unsaturated double bond is mainly used as a cross-link. The other unsaturated will not become the polymer backbone, only side chains. The main polymer chain of EPDM is fully saturated. This property makes EPDM resistant to heat, light, oxygen, and especially ozone. [0003] The currently used EPDM waterproof membrane has certain defects, lack of convenient clamping function, and it is easy to cause the main body of the waterproof membrane to fall off from the annular side of the reel. When clamping with a rubber band, the rubber band is easy to break, and the clamping effect At the same time, the tensile effect of the main body of the waterproof membrane and ...

Problems solved by technology

[0003] The currently used EPDM waterproof membrane has certain defects, lack of convenient clamping function, and it is easy to cause the main body of the waterproof membrane to fall off from the annular side of the reel. When clamping with a rubber band, the rubber band is easy to break, and the clamping effect Poor, at the same time, the tensile effect of the main body of the waterproof membrane and the effect of high temperature resistance are not good, which reduces the performance of the main body of the waterproof membrane
