Description
技术领域
本发明涉及一种防腐剂，具体是一种含有化合物HelikaurolideA的木材防腐剂，属于农业技术领域。
背景技术
到目前为止，最为常用防止木材腐朽的方法是用化学药剂防腐，防腐剂在生产和使用过程中的泄漏和渗出，以及防腐处理木材的废弃和燃烧都会对环境造成不利影响，并危害人类的健康。由于环境问题越来越受到人们的关注，也成为选择防腐剂的关键。
当前使用最多的是水溶性防腐剂，约占防腐剂使用总量的3/4。由于单一防腐剂抗木腐菌、虫的范围比较狭窄，现在一般将两种或几种防腐剂按一定比例混合，不但可以克服单一防腐剂使用时的不足之处，而且还会产生一些新的特性。目前，复合防腐剂已在世界各国得到了最广泛的应用，并取得了很好的效果。由于传统防腐剂存在诸多不足，迫使人们研究和寻找对人畜无害、对环境无污染、仅对微生物有毒的新型防腐剂。目前研究较多的包括水溶性的烷基铵类化合物(AAC)、氨溶烷基胺铜(ACQ)、硼化物、二甲基二硫代氨基甲酸铜(CDDC)和油溶性的百菌清(CTL)、有机碘化物(IPBC)等。对于木材防腐的实质，开发无毒、高效和实用的木材防腐方法，降低环境污染，对保护人类生态环境和充分利用现有资源意义深远。
HelikaurolideA首次发表于Helikaurolides A–D with a Diterpene-Sesquiterpene Skeleton from Supercritical Fluid Extracts of Helianthus annuusL.var.AriannaOrg.Lett.,2015,17(19),4730–473。其是从向日葵中分离出来的具有全新骨架的化合物，
申请人发现HelikaurolideA与千金子二萜醇在一定比例下配合对于木材防腐具有增效的效果。
发明内容
针对上述现有技术存在的问题，本发明的目的在于提供一种含有化合物HelikaurolideA的木材防腐剂，它是将两种不同结构、不同作用机理的成分进行复配，对木材起到防腐的作用。为实现本发明的目的，发明人将HelikaurolideA与千金子二萜醇复配，用于木材防腐。
为了实现上述目的，本发明采用的技术方案是:含有化合物HelikaurolideA的木材防腐剂，包含主要有效成分:HelikaurolideA。结构式如下：
所述的HelikaurolideA与千金子二萜醇的重量份数之比为1:1-30:1.
HelikaurolideA与千金子二萜醇的重量份数之比为1:1-30:1，有效成分占总重量的0.3％～10％。。
该组合物还包括辅助配方：水溶性高分子聚合物、表面活性剂、有机溶剂和水。
所述的水溶性高分子聚合物为共聚维酮、聚乙烯吡咯烷酮、苯乙烯-丙烯酸酯类聚合物中的任意一种。
所述的有机溶剂为正丙醇或者正丁醇。
有效成分0.1-5％，水溶性高分子聚合物0.6-4％，有机溶剂3-7％，余量水。
本发明通过将HelikaurolideA与千金子二萜醇配伍在特定的比例下发现具有很好的防霉效果，特别是在HelikaurolideA与千金子二萜醇的重量份数之比为23-25:1之间，其协同防霉效果非常的明显，而且毒性小，健康环保。
具体实施方式
千金子二萜醇，CAS号:34420-19-4，成都植标化纯生物技术有限公司等均有售。
本发明所涉及化合物HelikaurolideA的制备方法参见文献：(Helikaurolides A–D with a Diterpene-Sesquiterpene Skeleton from Supercritical Fluid Extractsof Helianthus annuus L.var.AriannaOrg.Lett.,2015,17(19),4730–473)。
效果试验:
试材 柳木，产自江苏省，5～10年生，无缺陷。去皮加工成精刨柳木条，并在自然环境下气干至含水率12％～15％。本实验中柳木全部加工成40mm×30mm×6mm(长×宽×厚)的试样.
霉菌:黑曲霉(AspergillusnigerV.Tiegh)，桔青霉(PenicilliumcitrintimThom)，菌种由中国林业科学研究院木材工业研究所提供。
实验设备
MJX-8503智能培养箱，BCL-1360-B型超净工作台等。
每组有22个柳木试样在不同的药液中常温浸渍处理时，根据处理时间3min按照常压浸渍法。将同一组的试样放在烧杯中井字形摆放，重物压顶以防止浮动，然后倒入药液并使其液面高出试样材顶2cm。取出后，擦掉试样表面的残液。空白对照组试样用无菌水浸泡，处理后的试样置于通风处，气干21天。
防霉效果评价
参照国家标准《防霉剂防治木材霉菌及蓝变菌的实验方法》，检测处理试样的室内防霉性能。试样接菌后的4周内，每3天观察记录一次试样的被害值以及试样表面发生霉变的程度，并参照试样的被害值。
| 试样表面发生霉变的程度 | 试菌感染面积被害值 |
| 试样表面无菌丝 | 0 |
| 试样表面感染面积＜1/4 | 1 |
| 试样表面感染面积1/4～1/2 | 2 |
| 试样表面感染面积1/2～3/4 | 3 |
| 试样表面感染面积＞3/4 | 4 |
药剂对霉菌的防治效力计算公式为:
E＝(1-Dt/D0)×100％式中:E为防治效力(％)；Dt为药剂处理试样的平均被害值；D0为未处理对照试样的平均被害值，
经过4周室内防霉实验后，不同浓度处理试样对霉菌的防治效力见表。
药剂的辅助配方为：聚乙烯吡咯烷酮2％，正丁醇5％，余量水。
A为HelikaurolideA，B为千金子二萜醇。
由实验结果可以看出单一的HelikaurolideA和千金子二萜醇具有一定的防霉效果，但是效果不显著，大量的试验表明只有HelikaurolideA与千金子二萜醇23-25:1)的比例对于霉菌的防治效果好，而其他比例组均不显著，可见HelikaurolideA与千金子二萜醇在23-25:1时协同防腐效果明显，具有显著的进步。
