| 但是昂貴的價格、阻燃和抗靜電性能差嚴重限制了這一材料的進一步應(yīng)用。本文選用廉價的水玻璃對聚氨酯注漿材料進行改性,研究了水玻璃與聚氨酯的共固化行為?疾炝肃彵蕉姿岫□OB及催化劑的含量對注漿材料固化時間和蓄熱溫度的影響;預(yù)聚體的種類及含量對注漿材料黏度及力學(xué)性能的影響、結(jié)合SEM測試結(jié)果分析了剪切速率對注漿材料雙組份的影響,并對固化機理進行了初步探索。 |

The further application of this material was severely limited by its expensive price and poor fire retardance and anti-static performance. The co-solidified behavior of water glass and polyurethane was investigated in this paper based on the modification of polyurethane grouting material by using cheap water glass. The effects of the contents of DOB and catalyst on curing time of grouting material and heat storage temperature and the prepolymer variety and content on viscosity and mechanical properties were studied in tihs paper.Then, the SEM was used to analyze the effect of shearing rate on two-component of grouting material, and a primary exploration of curing mechanism was made at last. |
