摘要:
 为使木材同时具有防腐防霉及阻燃等多重功能，将磷酸胍（GDP）、氨基磺酸胍（GS）、四水合八硼酸二钠（DOT）、十二烷基二甲基苄基氯化铵（DDBAC）根据正交试验进行不同比例的复配，制成N-P-B环保型木材防护剂并检测了其处理材的性能。结果表明，该防护剂不仅对腐朽菌和霉菌有较好防治效果，使处理材基本都达到了强耐腐等级，且处理材的氧指数是空白对照的1.72~2.71倍，此外对木材的抗吸水性也有积极影响。将正交试验结果利用矩阵法计算各因素水平的权重，根据权重大小，优选出的配方为2%的GDP，3%的GS，3%的DOT和0.5%的DDBAC。试验结果证实该N-P-B系木材复合防护剂能使各种药剂的功能协同化，实现“一剂多效”。
Abstract:
 In order to make woods to have multiple functions,such as decay and mold resistance,flame retardant,guanidine dihydrogen phosphate (GDP),guanidine sulfamate (GS),disodium octaborate tetrahydrate (DOT) and dodecyldimethylbenzylammonium chloride (DDBAC) were compounded in different proportions according to orthogonal design.Series of N-P-B wood protective agents were made and the properties of treated woods were tested.The results showed that these protective agents had better effects against decay fungi and mold,and the treated woods reached to the high decay resistance level.Compared with the control,the oxygen index of treated groups improved 1.72-2.71 times.In addition,there was a positive impact on water absorption resistance.Matrix analysis was used to calculate the weight of the factors and levels.According to the weights,the formulation of 2% GDP,3%GS,3% DOT and 0.5%DDBAC was selected as the optimized formula.The results revealed that there was synergistic effect among these reagents in the agent and realized the goal of “one dose with multiple effects”.
