High-toughness thin spraying material for rapid sealing reinforcement of underground coal mine and using method of high-toughness thin spraying material
The invention discloses a high-toughness thin spraying material for rapid sealing reinforcement of an underground coal mine and a using method of the high-toughness thin spraying material, belongs to the technical field of sealing reinforcement of coal mine tunnels, and aims to provide a thin spraying material which is relatively high in hardening speed, certain in strength, relatively good in toughness, excellent in ageing resistance and capable of reducing or avoiding the rebound rate. The thin spraying material is composed of a component A and a component B, wherein the component A is a liquid material composed of water-based polymer resin, and the component B is a powder material composed of Portland cement, sulphoaluminate cement, gypsum, an inorganic filler and a functional auxiliary agent. When being in use, the component A and the component B are mixed on pneumatic spraying equipment according to the proportion, and can be sprayed on site after being uniformly mixed. The spraying equipment is composed of a stirring barrel and a screw pump which are driven by high-pressure air and alternately work, and finally spraying is conducted through a pneumatic nozzle. The thin spraying material disclosed by the invention has the advantages of excellent sealing performance, high strength and large deformation rate, can realize rapid curing, and is safer, more convenient and more efficient in the construction process.
一种煤矿井下快速密闭加固用高韧薄喷材料及其使用方法，属于煤矿巷道密闭加固技术领域，目的在于提供一种具有较快的硬化速度，一定的强度、较好的韧性、优异的抗老化性能、可减少或避免回弹率的薄喷材料，该薄喷材料由AB两种组分组成。A组分由水性聚合物树脂组成的液体材料，B组分由硅酸盐水泥、硫铝酸盐水泥、石膏、无机填料、功能性助剂组成的粉体材料。使用时A、B组分按照配比在气动喷涂设备上进行混料，混合均匀后即可在现场进行喷涂。喷涂设备由高压空气驱动的搅拌桶和螺杆泵组成，交替工作，最后由气动喷嘴喷出。本发明的薄喷材料具有优良的密封性能、高强度及大变形率，能够实现快速固化，施工过程更安全、便捷、高效。
