摘　　要：针对糠醛-丙酮体系环氧灌浆材料中糠醛毒性大、易挥发及刺激性强等问题,将糠醛与含α-H的脂肪族醛通过羟醛缩合合成α,β-呋喃丙烯醛代替糠醛。研究了正丁醛、正戊醛、正庚醛等含α-H的脂肪族醛与糠醛之间的缩合反应,并对各产物性质及制备的环氧灌浆材料性能进行分析比较,优选3-呋喃基-2-乙基-丙烯醛(FEA)制备浆材,其中FEA产率达82.6%、沸程208℃~210℃及密度1.079 g/cm3。FEA作为稀释剂制备的浆材黏度为80 mPa.s^97.5 mPa.s、28 d压缩强度为96.76 MPa^99.98 MPa、拉伸剪切强度为5.07 MPa^6.06 MPa,是一种挥发度低、性能优异的环保型环氧灌浆材料。Furfural used as diluent was toxic,volatile and irritant in the epoxy grouting material of the furfural-acetone system.α,β-furyl-acrolein was synthesized by the Aldol condensation reaction using furfural and aliphatic aldehydes containing α-H to replace furfural in this paper.Reactions of n-butyraldehyde,n-valeraldehyde,n-heptylaldehyde and so on with furfural were investigated and properties of the environmental-friendly epoxy grouting material prepared by α,β-furyl-acrolein were compared with each other.In the epoxy grouting material,α,β-furyl-acrolein was used as the diluent replacing the toxic and volatile furfural.Comprehensively considering all facts,3-furyl-2-ethyl-acrolein（FEA） was selected as the epoxy grouting material diluent among the α,β-furyl-acrolein.The yield of product FEA was up to 82.6% and the boiling range,the density was 208 ℃～210 ℃,1.079 g/cm3 respectively.The results show the epoxy grouting material prepared by FEA has the properties of viscosity,the compressive strength and the tensile shear strength corresponding to 80 mPa·s～97.5 mPa·s,96.76 MPa～99.98 MPa,5.07 MPa～6.06 MPa respectively.It′s a kind of environmental-friendly epoxy resin grouting material with low volatility and excellent physical and mechanical properties.
