Mining bi-component ultra-strong thin-layer spraying material and preparation method and application thereof
The invention belongs to the technical field of building materials, and discloses a mining bi-component ultra-strong thin-layer spraying material and a preparation method and application thereof. The mining bi-component super-strong thin-layer spraying material is composed of a component A and a component B, and the mass ratio of the component A to the component B is 1: (0.9-1.1); the component A is prepared from the following components in parts by weight: 100 to 500 parts of cement, 100 to 400 parts of first sand component, 100 to 400 parts of second sand component, 100 to 300 parts of third sand component, 0.1 to 10 parts of polypropylene fiber and 0.1 to 5 parts of water reducing agent; the component B is prepared from the following components in parts by weight: 0.1 to 2 parts of hydroxypropyl methyl cellulose, 1 to 10 parts of bentonite and 100 to 300 parts of water. After the mining bi-component super-strong thin-layer spraying material is sprayed on the surface of a mine roadway, a firm protection layer can be formed, rock stripping and collapse are effectively prevented, and then the safety of a mine is effectively improved.
本发明属于建筑材料技术领域，公开一种矿用双组分超强薄层喷涂材料及其制备方法和应用。所述矿用双组分超强薄层喷涂材料由A组分和B组分组成，且所述A组分和所述B组分的质量比为1:0.9～1.1；A组分由以下重量份组分组成：水泥100～500份、第一砂组分100～400份、第二砂组分100～400份、第三砂组分100～300份、聚丙烯纤维0.1～10份和减水剂0.1～5份；B组分由以下重量份组分组成：羟丙基甲基纤维素0.1～2份，膨润土1～10份和水100～300份。本发明的矿用双组分超强薄层喷涂材料喷涂于矿山巷道表面后能够形成坚固的保护层，有效防止岩石的剥落和坍塌，进而有效提高矿山的安全性。
