Quick-setting inorganic anchoring material and preparation method thereof
The invention belongs to the technical field of anchoring materials, and discloses a quick-setting inorganic anchoring material which comprises the following components in parts by weight: 40-80 parts of overburnt magnesium oxide, 15-40 parts of phosphate, 2-12 parts of retarder, 1-5 parts of shrinkage reducing agent, 0-200 parts of sand, 0-12 parts of latex powder, 5-30 parts of mineral admixture, 0-4 parts of fiber and 10-25 parts of water. The invention also discloses a preparation method of the quick-setting inorganic anchoring material. The preparation method comprises the following steps: S1, weighing the raw materials; S2, mixing and dry-stirring other raw materials except water to obtain dry powder; and S3, mixing and stirring the dry powder and water to obtain the product. The quick-setting inorganic anchoring material has good fire resistance and durability, and can avoid safety accidents caused by aging or fire failure of an anchoring structure; meanwhile, the grouting material is quick in setting and hardening, high in early strength, high in volume stability, high in bonding strength and quick in hydration heat release, the anchoring effect can be effectively improved, and the construction time can be effectively shortened; in addition, hydration heat release is fast, and construction can be conducted under the negative temperature condition.
本发明锚固材料技术领域，公开了一种快固型无机锚固材料，按重量份计，包括过烧氧化镁40～80份、磷酸盐15～40份、缓凝剂2～12份、减缩剂1～5份、砂0～200份、乳胶粉0～12份、矿物掺合料5～30份、纤维0～4份和水10～25份；本发明还公开了该快固型无机锚固材料的制备方法，包括以下步骤：S1.称取原料；S2.将除水以外的其他原料混合干拌，得到干粉料；S3.将所述干粉料和水混合搅拌，即得；该快固型无机锚固材料具有良好的耐火性和耐久性，能够避免锚固结构因老化或火灾失效而造成安全事故；同时，其凝结硬化快、早期强度高、体积稳定性高、粘结强度高且水化放热快，可有效提高锚固效果和缩短施工时间；另外，其水化放热快，可在负温条件下进行施工。
