摘要: 以天然产物腰果酚为原料合成表面活性剂腰果酚聚氧乙烯醚(CPE)并进行红外光谱及核磁共振氢谱表征;将CPE与其他市售表面活性剂脂肪醇聚氧乙烯醚(AEO-9)、脂肪醇聚氧乙烯醚硫酸盐(AES)、十二烷基硫酸钠(K12)、吐温-60(Tween-60)和吐温-80(Tween-80)进行单一及复配使用,用于混合办公废纸浮选脱墨。结果表明:CPE对混合办公废纸有较好的脱墨效果,且具有良好的配伍性,与多种表面活性剂复配可以达到更好的效果。CPE与其他表面活性剂三组分复配使用时脱墨效果优于双组分使用,更优于CPE单独使用。当CPE/AEO-9/AES质量比为1:1:1复配使用时效果最好,脱墨浆白度达到90.45%(ISO),油墨去除率达到91.96%,纸浆得率75.7%。

Abstract: Cardanol polyoxyethylene ether(CPE) was prepared from natural cardanol and characterized by FT-IR and 1H NMR. By combining with other commercially available surfactants(fatty alcohol polyoxyethylene ether (AEO-9),fatty alcohol polyoxyethylene ether sulfate(AES),sodium dodecyl sulfate (K12),Tween-60 and Tween-80), CPE was used as flotation deinking agent of mixed office waste paper. The experimental results showed that CPE was effective and compatible, which could achieve better effect when mixed with a variety of surfactants. The deinking effect of CPE compounded with other two surfactants was better than that of double components and CPE alone. Results showed that the blend of three surfactants, composed of CPE:AES:AEO-9 with mass ratio of 1:1:1, could provide best effect, and the brightness of the recycled paper product reached to 90.45%(ISO), ink removal efficiency was 91.96% and pulp yield reached to 75.7%.
