High-viscosity anti-seepage slow-bonding prestressed steel strand and preparation method and application thereof
The invention relates to a high-viscosity anti-seepage slow-bonding prestressed steel strand and a preparation method and application thereof.The high-viscosity anti-seepage slow-bonding prestressed steel strand comprises a prestressed steel strand body, a slow-setting adhesive layer and a high-viscosity anti-seepage sheath, the prestressed steel strand body is wrapped with a slow-setting adhesive, the slow-setting adhesive is wrapped with the high-viscosity anti-seepage sheath, and the high-viscosity anti-seepage sheath is arranged on the outer side of the slow-setting adhesive. And the surface hydrophilic angle theta of the high-viscosity impermeable sheath is less than or equal to 60 degrees. The surface of the sheath of the high-viscosity anti-seepage retard-bonding prestressed steel strand has strong bonding force with concrete, the anti-seepage grade of the high-viscosity anti-seepage retard-bonding prestressed steel strand is not less than P7, and the problem of waterproofness of the existing retard-bonding steel strand is solved.
本发明涉及一种高粘抗渗缓粘结预应力钢绞线及其制备方法和应用，该高粘抗渗缓粘结预应力钢绞线包括预应力钢绞线、缓凝粘合剂层和高粘抗渗护套，缓凝粘合剂包裹在预应力钢绞线的外侧，高粘抗渗护套包裹在缓凝粘合剂的外侧，高粘抗渗护套的表面亲水角θ≤60°。本发明的高粘抗渗缓粘结预应力钢绞线的护套表面与混凝土粘结力强，高粘抗渗缓粘结预应力钢绞线的抗渗等级不小于P7，克服了现有缓粘结钢绞线的防水性问题。
