Filling material for fission-resistant tunnel outer wall and preparation method of filling material
The invention relates to an anti-fission filling material for an outer wall of a tunnel and a preparation method of the anti-fission filling material. The anti-fission filling material comprises the following raw materials in parts by mass: 80-120 parts of wollastonite, 16-25 parts of modified silicon dioxide nanotubes, 60-82 parts of polymer polyol, 15-25 parts of activated wood flour, 5-6.5 parts of a silane coupling agent and 30-43 parts of isocyanate. According to the invention, a component I containing modified silicon dioxide nanotubes, activated wood flour and polymer polyol and a component II containing wollastonite and isocyanate are subjected to a chemical reaction at room temperature to obtain the fission-resistant filling material for the outer wall of the tunnel, and the fission-resistant filling material has high elasticity, strength, fatigue resistance and isotropy.
本发明涉及一种抗裂变隧道外壁用填充材料及其制备方法，填充材料包括以下质量份数的原料：硅灰石80‑120份、改性二氧化硅纳米管16‑25份、聚合物多元醇60‑82份、经活化处理的木粉15‑25份、硅烷偶联剂5‑6.5份和异氰酸酯30‑43份。本发明将含有改性二氧化硅纳米管、经活化处理的木粉和聚合物多元醇的组分一与含有硅灰石和异氰酸酯的组分二，通过室温下的化学反应，得到一种具有较高弹性、强度、抗疲劳性以及各向同性的抗裂变隧道外壁用填充材料。
