The invention discloses novel high-viscosity supporting guniting and a preparation method thereof, relates to the field of mine underground supporting guniting materials, aims to solve the problems of poor adhesion and high rebound rate in the prior art, and adopts the technical scheme that the novel high-viscosity supporting guniting comprises cement, gypsum, desulfurized gypsum, fly ash, tailings, an accelerator, a water reducer and a tackifier. The aggregate, the cementing material and the polymer additive are added, and the surface of the cementing material is covered with a film formed by a polymer, so that a cementing material matrix and the aggregate are strongly bonded; and by enhancing the binding force between the aggregate and the rubber material and reducing the resilience, high viscosity is taken as a main component, and rapid setting is taken as an auxiliary component, so that the obtained guniting material is high in cohesiveness and low in resilience rate.
本发明公开了一种新型高粘性支护喷浆及其制备方法，涉及矿山井下支护喷浆料领域，旨在解决现有技术中粘接性差，回弹率高的问题，采用的技术方案是，包括水泥、生石膏、脱硫石膏、粉煤灰、尾砂、速凝剂、减水剂、增粘剂。通过添加骨料、胶材和聚合物助剂，利用聚合物成膜覆盖在胶凝材料表面，使胶凝材料基体与骨料之间形成强有力的粘结；通过增强骨料和胶材之间的结合力，而降低回弹需要以高粘为主，以快凝为辅，使获得的喷浆料粘结性高、回弹率低。
