Abstract

The invention discloses a high-fusion type water-stop strip, comprising a high-viscosity fusion layer and a combined steel belt, wherein the fusion layer comprises the following components in percent by weight: 35-45% of cement bituminous mortar, 20-30% of filler, 0.4-0.8 of cellulose ether, 4-7% of adhesive, 0.1-0.5% of lignocellulose, 0.1-0.3% of thixotropic agent, 0.1-0.2% of water reducing agent, 5-10% of SBS (styrene butadiene styrene), 4-10% of SPAO, 8-10% of softener, 4-9% of tackifying resin and 0.5-0.8% of aging agent. According to the high-fusion type water-stop strip, the fusion layer can be self healed and can be microcosmically completely wet with concrete to generate intermolecular forces; new concrete and old concrete are perfectly fused, the bonding strength is high, and liquid water and water vapor are effectively blocked from leaking into a structural body through construction joints; the service life of the galvanized combined steel belt is prolonged, and a rust removing operation in the subsequent construction procedure is avoided.

Description

technical field [0001] The invention relates to a connection material for a joint surface, in particular to a highly fused waterstop with strong adhesion. Background technique [0002] With the continuous expansion of the scale of modern cities, the country is building large-scale construction projects, and concrete pavement can be seen everywhere on roads and bridges. The complex transportation network facilitates our lives, but the road surface is often damaged or aging during continuous use. Damaged pavement needs to be repaired or resurfaced. During the construction process, after the new pavement is laid, it is necessary to connect the old and new pavement. The orientation of the joint surface, the treatment method of the joint surface, the raw and cooked concrete ingredients and vibration control of the new and old concrete all affect the waterproof quality of the project. In order to ensure the construction quality and make the concrete of the new and old pavements p...
