Problems solved by technology

However, when the rubber coil is bonded to the base surface of the structure, the bonding condition requires that the moisture content of the base surface be less than or equal to 8%, otherwise the construction cannot be carried out, and the use is limited; moreover, the adhesive also pollutes the environment and has high costs. ills

Abstract

Production of high-strength self-adhesive hung and spreading coiling material of composite water-proof rubber is carried out by preparing non-vulcanized rubber sheet, synthesizing rubber 100, tack producing agent-polyisobutylene 8-10, improver 1.0-1.6 and hydrophilic agent-sodium oleate 2-5 proportionally, cooking, milling, laying aside for 24 hrs, calendaring or extruding into slices, preparing un-vulcanized rubber sheet, synthesizing rubber 100, activator 2.5-5, vulcanizing agent-S1-5 and improver 2-4 proportionally, milling, laying aside for 24 hrs, cooking at 70-80 degree, forming by calendaring stack or extruder, combining, and passing non-woven fabric sheet, vulcanized rubber sheet and non-vulcanized rubber sheet through vulcanizing drum successively to obtain final product. The products consist of non-woven fabric layer, vulcanized rubber layer and non-vulcanized rubber layer. It has better affinity with concrete, penetration resistance and extendibility and no leakage. It can be used for water proofing layer of underground architecture.

Description

Technical field: [0001] The invention relates to a manufacturing method of a waterproof component used for the waterproof layer of underground structures. In particular, the invention relates to a manufacturing method of a high-strength self-adhesive rubber composite waterproof hanging paving coil. Background technique: [0002] Underground structures must be provided with a waterproof layer due to the impact of the groundwater level. For the waterproof layer of the vertical wall, its bottom surface needs to have affinity with the wet base of the structure, and its upper surface must have a firm bond with the concrete; in addition, the waterproof layer must also withstand vibration and extrusion, and must have a certain Strength of. [0003] At present, rubber coils are often used as waterproof components for the waterproof layer of underground structures. During construction, the rubber coils are bonded to the base surface of the structure to form a waterproof layer. How...
