Description
技术领域
本申请属于化学驱鸟驱虫剂技术领域,具体涉及微胶囊驱鸟驱虫剂、缓释型液体驱鸟驱虫剂及其制备方法。
背景技术
随着全国环境保护意识的增强,鸟的种类、数目急剧增加。然而随着鸟类数量的不断增多,鸟类给农作物播种及收获等方面带来了越来越多的问题。作物刚刚播种时,鸟类会刨食种子,危害作物播种,造成出苗不齐;作物成熟时,鸟类会啄食作物,造成作物减产和质量下降;同时一些栽培方式使果穗外露,更易遭到鸟类的侵袭。甚至套袋的果实也会受到诸如灰喜鹊、乌鸦等长嘴鸟类的危害。
目前,应用于防鸟的传统驱鸟手段是利用巨大声响或视觉效果使鸟类受到惊吓来驱鸟,如敲锣、放炮、装稻草人等,这些方法由于具有单一性,费时费力,驱鸟效果不佳。果穗套袋、设防鸟网等成本高,效果也并不理想,新开发的一系列驱鸟产品,如超声波驱鸟剂、激光驱鸟器等。但这些仪器价格较为昂贵,也具有一定的使用限制,难以大规模推广应用。近年来,农用化学驱鸟驱虫剂以其使用的简便性以及价格的低廉性,应用越来越普遍,但目前大多数驱鸟及驱虫剂药效时间短,或者随着使用时间增长,药效明显下降,使用效果不佳。

图2是本申请的缓释型液体驱鸟驱虫剂的制备方法中的实施例1的驱鸟驱虫剂的产品示意图;
图3是本申请的缓释型固体驱鸟驱虫剂的制备方法中实施例1的测试实验示意图。
具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本申请的一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请一实施例提供了一种微胶囊驱鸟驱虫剂,微胶囊包括复配药剂和微胶囊壁材。其中,复配药剂包括驱鸟剂和驱虫剂,从而同时具有驱鸟及驱虫的效果;微胶囊壁材包覆于复配药剂表面,有效保护内部的复配药剂,微胶囊壁材包括明胶-阿拉伯胶复合膜层。
由于微胶囊壁材包覆于驱鸟剂和驱虫剂形成的复配药剂表面,可减缓复配药剂的挥发速率,达到缓慢持久的缓释目的。本申请的微胶囊驱鸟驱虫剂能够缓慢释放,挥发时效长,延长驱鸟剂和驱虫剂的作用时间,具有有效的驱虫驱鸟效果;并且,微胶囊驱鸟驱虫剂的耐候性强,遇到大风或雨水天气,驱鸟剂和驱鸟剂的有效成分不易流失,耐雨水冲刷,可以直接布点放置在需要驱鸟驱鸟的施用范围内;同时,微胶囊驱鸟驱虫剂稳定性强,体积小,利于运输和保存。
明胶-阿拉伯胶复合膜层制备机理如下:明胶是由多种氨基酸组成的线性高分子结构,既含羧基又含氨基, 是两性离子电解质。溶液 pH值高于等电点时,明胶以酸式电离为主,分子带负电荷;溶液 pH 值低于等电点时,明胶以碱式电离为主,分子带正电荷。所以,通过改变溶液的pH 值,可使明胶成为聚阳离子或者成为聚阴离子。而阿拉伯胶分子含大量的羧酸基团,是带负电荷的聚阴离子,在明胶-阿拉伯胶水溶液中,溶液 pH 低于明胶等电点时,就能使作为聚阳离子的明胶和聚阴离子的阿拉伯胶产生静电作用,发生复凝聚反应,在复配药剂的液滴或结晶体微粒表面凝聚成膜,再用甲醛固化成膜,最终形成稳定的微胶囊结构。
微胶囊壁材的质量占微胶囊总质量的15%-30%,例如15%、20%、25%或者30%等。通过调节微胶囊壁材的质量占微胶囊总质量,可以控制微胶囊驱鸟驱虫剂的大小,并实现微胶囊驱鸟驱虫剂的缓释周期可控,产品适用范围广,适应性强。
具体地,驱鸟剂包括邻氨基苯甲酸甲酯、邻氨基苯甲酸乙酯、肉桂醛、薄荷油、薄荷酮中的一种或多种。其中,邻氨基苯甲酸甲酯,为无色结晶或浅黄色液体,有葡萄样气味,易溶于乙醇、乙醚及大多数不挥发油和丙二醇,天然存在于葡萄、草莓、红葡萄酒及白葡萄酒中,有一定的驱鸟效果。肉桂醛是一种醛类有机化合物,为黄色黏稠状液体,大量存在于肉桂等植物体内。自然界中天然存在的肉桂醛均为反式结构,该分子为一个丙烯醛上连接上一个苯基,因此可被认为是一种丙烯醛衍生物。肉桂醛对传播黄热病的伊蚊幼虫有很强的杀灭效果,为新型的杀虫剂。肉桂醛不仅安全环保而且气味芬芳,含有肉桂醛的抗微生物剂,可驱避昆虫。邻氨基苯甲酸甲酯和肉桂醛均具有优良的驱鸟效果,且成分天然,低毒安全。优选地,驱鸟剂可以选择多种单剂复配形成,例如驱鸟剂可同时包括邻氨基苯甲酸甲酯和肉桂醛。研究发现,与单剂相比,复配驱鸟剂对鸟类有很好的驱避作用,多药剂之间存在明显增效作用,从而显著减少用药量,达到安全、经济、环保的目的。复配驱鸟剂对鸟类直接杀伤性很小,不会对鸟类造成毒害;对人类和其他哺乳动物毒性低;对作物安全。并且复配驱鸟剂持效期长,有利于进一步实现缓释的目的。驱鸟剂的质量占微胶囊总质量的40%-60%,例如40%、50%或者60%等。
进一步地,驱虫剂包括萘、2-萘酚、对二氯苯、间二氯苯、樟脑中的一种或多种。驱虫剂的质量占微胶囊总质量的30%、35%或者40%等。通过调节驱鸟剂中组分的种类和含量,可使得驱鸟剂的缓释周期可控,产品适用范围广,适应性强。本申请创新采用驱鸟剂与驱虫剂复配的方式,达到综合协同驱鸟的目的。驱虫剂为气味型缓释驱虫剂,产品具有升华特性,可与驱鸟剂产生协同作用,散发出的复配气味在提升驱鸟效果的基础上,引入驱虫效果,在生物链角度减少区域内食物对鸟类的吸引,从而有效提升驱鸟效果。
本申请又一实施例提供了一种缓释型液体驱鸟驱虫剂,液体驱鸟驱虫剂包括微胶囊、乳化剂、增粘剂和水。其中,微胶囊为上述任一实施例中的微胶囊驱鸟驱虫剂,微胶囊的质量占液体驱鸟驱虫剂的20%-50%,例如20%、30%、40%或者50%等;乳化剂的质量占液体驱鸟驱虫剂的10%-20%,例如10%、15%或者20%等;增粘剂的质量占液体驱鸟驱虫剂的1%-10%,例如1%、5%或者10%等。
具体地,乳化剂包括阴离子型乳化剂,乳化剂包括脂肪酸皂、十二烷基硫酸钠、十二烷基苯磺酸钠等中的一种或几种;和/或,乳化剂包括非离子型乳化剂,乳化剂包括吐温系类,司盘系列中的一种或多种。增粘剂包括有机纤维素类增粘剂,增粘剂包括甲基纤维素、羟甲基纤维素、羧甲基纤维素钠等中的一种或几种;和/或,增粘剂包括多糖类增粘剂,增粘剂包括各种淀粉、阿拉伯胶、琼脂、海藻胶、糊精等中的一种或几种;和/或,增粘剂包括无机粘土类增粘剂,增粘剂包括蒙脱土等。
其中,乳化剂和增粘剂可以调节粘度,解决微胶囊的沉降问题,使其均匀分散在水相中,在使用时,加入大量水稀释后,可直接喷洒在目标区域,使用方便;并且本申请的液体驱鸟驱虫剂包含微胶囊,微胶囊中的复配药剂采用驱鸟剂与驱虫剂复配的方式,达到综合协同驱鸟的目的;微胶囊能够缓慢释放驱鸟驱虫活性成分,挥发时效长,延长驱鸟剂和驱虫剂的作用时间;本申请采用天然动植物原料,可完全降解,无残留,环保且高效。

制备获得微胶囊块体后,需要将微胶囊块体稀释分散,并加入乳化剂和增粘剂调节至预设粘度,获得液体驱鸟驱虫剂,具体包括如下步骤:
S105:将第一预设质量的微胶囊块体稀释于第二预设质量的水中,分散均匀,获得微胶囊分散液。

S106:在微胶囊分散液中加入乳化剂和增粘剂,调节粘度至2000~4000cP,获得液体驱鸟驱虫剂。
在上述微胶囊分散液至加入乳化剂10-20份,持续搅拌,后加入2-10份增粘剂,继续搅拌至粘度至2000~4000cP,即得到缓释型液体驱鸟驱虫剂。
明胶是由多种氨基酸组成的线性高分子结构,既含羧基又含氨基, 是两性离子电解质。溶液 pH值高于等电点时,明胶以酸式电离为主,分子带负电荷;溶液 pH 值低于等电点时,明胶以碱式电离为主,分子带正电荷。所以,通过改变溶液的pH 值,可使明胶成为聚阳离子或者成为聚阴离子。而阿拉伯胶分子含大量的羧酸基团,是带负电荷的聚阴离子,在明胶-阿拉伯胶水溶液中,溶液 pH 低于明胶等电点时,就能使作为聚阳离子的明胶和聚阴离子的阿拉伯胶产生静电作用,发生复凝聚反应,在复配药剂的液滴或结晶体微粒表面凝聚成膜,再用甲醛固化成膜,最终形成稳定的微胶囊结构。
本方法步骤简单,且通过本方法制备获得的缓释型液体驱鸟驱虫剂可经水稀释后直接喷洒在目标区域,使用方便;并且本方法制备获得的缓释型液体驱鸟驱虫剂包含微胶囊,微胶囊中的复配药剂采用驱鸟剂与驱虫剂复配的方式,达到综合协同驱鸟的目的;微胶囊能够缓慢释放驱鸟驱虫活性成分,挥发时效长,延长驱鸟剂和驱虫剂的作用时间;并且本方法制备采用天然动植物原料,可完全降解,无残留,环保且高效。
