我国橡胶木防腐剂自1980年采用硼酚合剂以来,至今仍在普遍使用。海南省年产橡胶木约10万m~3,经防腐和干燥处理后出口,价值1000多万美元。但由于硼酚合剂含有25—35％五氯酚钠,具有刺激性气味。国外还发现氯化酚除莠剂中含有二噁英(dioxins)杂质,对哺乳类动物的毒性较大。1978年瑞典首先禁止使用五氯酚钠防治木材蓝变,接着日本,印度尼西亚以及其他国家也相继禁止或控制使用。我国也已把五氯酚钠列为高毒农药。目前,广东和海南等省通过进口防腐剂以代替硼酚合剂,化费大量外汇。因此,寻找新型不含氯化酚的
Our rubber wood preservatives since the use of boron phenolic mixture since 1980, is still in widespread use. Hainan Province, with an annual output of about 100,000 rubber m ~ 3, after anti-corrosion and drying exports, the value of more than 10 million US dollars. However, since the boron phenolic mixture contains 25-35% sodium pentachlorophenate, it has an irritating odor. Foreign countries also found that chlorinated phenol herbicides containing dioxins (dioxins) impurities, mammals more toxic. In 1978, Sweden banned the use of sodium pentachlorophenol for the first time in controlling the blue-stain of wood. Subsequently, Japan, Indonesia and other countries also banned or controlled the use of sodium pentachlorophenate. China has also listed pentachlorophenol as a highly toxic pesticide. At present, Guangdong and Hainan provinces, through the import of preservatives to replace the boron compound, cost a lot of foreign exchange. Therefore, looking for a new type of non-chlorinated phenol
