    摘 ? 要:采用堿溶液浸泡和煮沸對椰殼纖維進行預處理,研究了處理時長對椰殼纖維吸水率、表面形貌、拉伸強度、彈性模量和表面靜摩擦力的影響,并將預處理椰殼纖維摻入到水泥基材料中,研究了預處理椰殼纖維對水泥基材料拉伸性能和彎曲性能的影響。結果表明:與未處理椰殼纖維相比,煮沸處理2 h或堿處理5 h后,椰殼纖維的吸水率分別降低了40.25%、48.56%,拉伸強度分別降低了3.26%、5.54%,彈性模量分別降低了8.71%、3.32%,表面靜摩擦力分別提高了209.41%、262.35%;采用濃度為15%的有機硅烷溶液浸泡預處理椰殼纖維后,再將預處理椰殼纖維分別按質量比m堿處理∶m煮沸處理=3∶1、m堿處理∶m煮沸處理=1∶1混摻時,水泥基材料的拉伸強度、彎曲強度較空白組分別提高了76.08%、68.04%。 Abstract: The coir fiber was pretreated by soaking and boiling in alkali solution, and the effects of treatment time on water absorption, surface morphology, tensile strength, elastic modulus and surface static friction of coir fiber were studied. The pretreated coir fiber was incorporated into cement-based material, and the effect of the pretreated coir fiber on the tensile and bending properties of cement-based material was studied. The results show that compared with the untreated coir fiber, after boiling for 2 h or alkali treatment for 5 h, the water absorption of coir fiber decreases by 40.25% and 48.56%, the tensile strength decreases by 3.26% and 5.54%, the elastic modulus decreases by 8.71% and 3.32%, and the surface static friction increases by 209.41% and 262.35% respectively. After the pretreated coir fiber is soaked in organosilane solution with the concentration of 15%, and then the pretreated coir fiber is blended according to the mass ratio of malkali treatmen∶mboiling treatment=3∶1 and malkali treatmen∶mboiling treatment=1∶1, the tensile strength and flexural strength of the cement-based material is increased by 76.08% and 68.04% respectively compared with the blank group.
