【摘要】 利用二甲基二癸基氯化铵(DDAC)、五水合硫酸铜、氨水或乙醇胺合成3种不同的氨溶烷基铜铵(ACQ,包括A型、B型、D型)。以樟子松和三倍体毛白杨为试材, ACQ为防腐剂对绿色木霉进行防腐性能研究, 通过比较试样经绿霉菌腐蚀后的质量损失率来分析ACQ类型、浓度、树种类别对ACQ防腐性能的影响; 并比较试样经抽提后质量损失率来分析酸碱度, 助剂对ACQ抗流失性能的影响。结果表明: 在相同处理条件下, 3 种ACQ在较低浓度(0 5%)下均能达到强耐腐等级, 耐腐性能满足要求; ACQ在浓度高于0 5%时, 防腐效果较好; ACQ在碱性环境中固着率高于酸性环境。更多还原

【Abstract】 Ammonium Copper Quaternary (ACQ) is a novel wood preservative. DDAC, copper sulfate pentahydrate, ammonium hydroxide or ethanolamine were used to synthesize three different kinds of ACQ(type A, type B, and type D). Pinus sylvestnis var. mongolica Litv. and poplar were used as test materials in studies of the ACQ preservative performances against green woods mold. By comparing weight loss of test samples after decay caused by green woods mold, the influences of ACQ type, concentration, and wood type on the ACQ preservative performance were investigated.The effects of pH and additives on antiloss performance of ACQ were also studied by comparing weight loss percentage after sample extraction. Results showed that under the same circumstances, all three kinds of ACQ reached the high antidecay level at the relatively low concentration of 0 5%. Preservative effects became stronger as the concentration increased to more than 0 5%. Adhesive property of ACQ in alkaline environment was better than in acid.更多还原
