Method for preparing pesticide auxiliary by use of spent bleaching clay

一种利用废白土制备绿色农药助剂的方法

Abstract

The invention discloses a method for preparing a pesticide auxiliary by use of spent bleaching clay and belongs to the field of waste utilization. Aiming at the problems of environmental pollution, resource waste and high difficulty in degradation of conventional pesticide auxiliaries, caused by adopting a burying manner in a traditional spent bleaching clay handling method, the method disclosed by the invention comprises the following steps: firstly soaking the spent bleaching clay with ethanol, performing sonic oscillation, taking out part of impurities in the spent bleaching clay, performing biological modification by virtue of fermentation broth, then mixing with additives such as magnesium sulfate, thereby preparing the pesticide auxiliary which is environment-friendly and free from environmental pollution. According to detection, the emulsifying ability of the pesticide auxiliary prepared by the method is improved by 20-30% in comparison with that of the traditional pesticide auxiliary, the wetting power is up to 10-18s, the seepage force is up to 98-99.5s, and the pesticide dosage is reduced by 5-10%.
本发明公开了一种利用废白土制备绿色农药助剂的方法,属于废弃物利用领域。本发明针对目前传统的废白土的处理方法,采用掩埋的方式,产生了环境污染及资源浪费,同时目前传统的农药助剂很难降解的问题,本发明首先通过对废白土进行乙醇浸泡,超声振荡,取出废白土中的部分杂质,再通过与发酵液进行生物改性后,再与硫酸镁等添加剂进行混合,制得一种绿色,对环境无污染的农药助剂。通过检测得本发明所制的农药助剂乳化力比传统农药助剂提供了20~30%,润湿力达到10~18s,渗透力达到98~99.5s,农药用量减少了5~10%。
