Description

丙硫菌唑可分散油悬浮剂
本申请要求于2018年12月26日提交中国专利局、申请号为201811598012.3、发明名称为“丙硫菌唑可分散油悬浮剂”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及杀菌剂技术领域，尤其涉及一种丙硫菌唑可分散油悬浮剂。
背景技术
丙硫菌唑，是由拜耳作物科学公司发现、开发并生产的新型广谱三唑硫酮类杀菌剂。丙硫菌唑为甾醇脱甲基化(麦角甾醇生物合成)抑制剂，其不仅具有良好的内吸作用，优异的保护、治疗和铲除活性，而且持效期长。大量的田间药效试验结果表明：丙硫菌唑对作物安全性好，防病治病效果好，而且增产明显。丙硫菌唑主要用于防治小麦、大麦、油菜、花生、水稻、豆类作物、甜菜和大田蔬菜等作物上的病害。同三唑类杀菌剂相比，丙硫菌唑具有更广泛的杀菌谱。几乎对所有麦类病害具有很好的防治效果，如小麦和大麦上的白粉病、纹枯病、枯萎病、叶斑病、锈病、菌核病、网斑病、云纹病等；还能防治油菜和花生的土传病害，如菌核病，以及主要叶面病害，如灰霉病、黑斑病、褐斑病、黑胫病、菌核病和锈病等。而且，更难能可贵的是丙硫菌唑无环境风险关注点，即丙硫菌唑对蜂、鸟、鱼、蚕、水藻、水蚤、蚯蚓、天敌赤眼蜂等安全。
可分散油悬浮剂，英语简称为OD，是一种或一种以上的农药有效成分(其中一种为固体原药)在非水系分散介质中形成高分散、稳定的悬浮体系。优点：用植物油、矿物油等，不用有机溶剂，毒性低、易降解，对环境友好；闪点高，比乳油更安全；植物油和矿物油、油酸甲酯等可以提高制剂药效；对一些易水解的固体原药尤其适合(比如烟嘧磺隆)；在缺水的干旱地区或者飞机喷洒施药情况下，希望少用、甚至不用水，或者用超低容量喷雾，也可直接用油悬浮剂(要符合ULV标准)喷雾更为经济方便。
发明内容
有鉴于此，本发明要解决的技术问题在于提供一种丙硫菌唑可分散油悬浮剂，具有较高的悬浮稳定性。
为解决以上技术问题，本发明提供了一种丙硫菌唑可分散油悬浮剂，按照重量百分数计算，包括：

本发明使用聚合羧酸盐分散剂，相比传统分散剂提高了丙硫菌唑在油溶剂中的分散性，其与油溶剂的相溶性好，电荷密度大，分子量适中，呈梳型结构，可以有效的包裹原药颗粒表面，避免了产品在储存过程中容易发生沉降的情况。
所述黏度调节剂的重量百分数含量为0.5％～6％，进一步优选为1.5％～2.5％。
本发明中，所述黏度调节剂为有机膨润土和气象白炭黑组成的混合物，优选的，所述有机膨润土和气象白炭黑的质量比为(1～3):(3～1)，进一步优选为1：3。
本发明采用有机膨润土和气象白炭黑的混合物作为丙硫菌唑可分散油悬浮剂的黏度调节剂，其中，有机膨润土可以调节体系黏度，使体系具有触变性，呈悬浮状态。气象白炭黑全部是纳米二氧化硅，其粒径在10～20nm，具有超高的表面积和非常强的吸附力，其与有机膨润土混合后，提高了其触变性能，防止制剂结块，有非常好的亲和性以及物理化学稳定性，提高了悬浮剂在低温、高温的稳定性。有利于黏度调节剂与丙硫菌唑原药作用，提高其稳定性。
所述消泡剂优选为有机硅。
所述消泡剂的重量百分数含量为0.1％～1％，进一步优选为0.5％。

所述改性大豆油、油酸甲酯和矿物油的质量比优选为(1～3):(1～6):(1～2)，进一步优选为1：3～6：1。
本发明的丙硫菌唑可分散油悬浮剂使用了改性大豆油、油酸甲酯、矿物油的混合油溶剂，使其在作物面展着渗透性比水溶剂的效果要强，减少了有效成分流失，有明显增效作用。
本发明对所述丙硫菌唑可分散油悬浮剂的制备方法并无特殊限定，可以为本领域技术人员熟知的可分散油悬浮剂的制备方法。
本发明提供了上述丙硫菌唑可分散油悬浮剂的制备方法，包括以下步骤：

在本发明的一些具体实施例中，所述丙硫菌唑可分散油悬浮剂按照以下方法制备：
向混合釜内加入丙硫菌唑原药、乳化剂、聚合羧酸盐分散剂、消泡剂、有机膨润土、气象白炭黑和改性大豆油、油酸甲酯、矿物油，在高剪切搅拌下，使物料充分混合均匀，将混合物料打入砂磨机中研磨，砂磨1～2h，制备得到丙硫菌唑可分散油悬浮剂。
与现有技术相比，本发明提供了一种丙硫菌唑可分散油悬浮剂，按照重量百分数计算，包括：丙硫菌唑10％～30％、乳化剂8％、聚合羧酸盐分散剂5％、黏度调节剂4％、消泡剂0.5％，余量为油；所述黏度调节剂为有机膨润土和气象白炭黑组成的混合物。本发明提供的丙硫菌唑可分散油悬浮剂性能稳定，相对于乳油剂型，本发明的丙硫菌唑可分散油悬浮剂减少了有机溶剂的使用，更环保、安全，贮运和使用安全，且对环境友好，符合当今农药剂型的发展方向，相对于水悬浮剂剂型，本发明的丙硫菌唑可分散油悬浮剂产品悬浮性能更稳定，有效期长，不会出现水悬产品严重沉淀的现象。
实验结果证明，该悬浮剂不仅悬浮稳定性高，满足不同水质地区、高海拔地区、低温地区、赤道附近高温地区的需要，又减少了有机溶剂对环境的影响。
