Silanized alcohol amine modified lignin asphalt anti-stripping agent
The invention discloses a silanized alcohol amine modified lignin asphalt anti-stripping agent. The asphalt anti-stripping agent is prepared by a two-step method: firstly, lignin, formaldehyde and N-(2-ethoxyl) ethylenediamine react to prepare alcohol amine modified lignin, and then the alcohol amine modified lignin reacts with trimethylchlorosilane to prepare the silanized alcohol amine modified lignin asphalt anti-stripping agent. After the anti-stripping agent is added into the asphalt, the adhesion between the asphalt and aggregate is greatly improved. The anti-stripping agent has good compatibility with asphalt, is convenient to use and has important application value.
本发明公开一种硅烷化醇胺改性木质素沥青抗剥离剂。该沥青抗剥离剂通过两步法制备：先由木质素、甲醛、N‑(2‑羟乙基)乙二胺反应，制备醇胺改性木质素，然后由醇胺改性木质素和三甲基氯硅烷反应，制备硅烷化醇胺改性木质素沥青抗剥离剂。在沥青中添加该抗剥离剂后，沥青与集料的粘附性大大提高。抗剥离剂与沥青相容性好，使用方便，具有重要应用价值。
