目的研制一种高效、安全、使用简便及性能可靠的快速杀虫烟剂。方法参照有关国家标准,对该杀虫烟剂性能、药效及毒性进行试验观察。结果该杀虫烟剂以溴氰菊酯为有效成分,辅以氧化剂、阻燃剂等成分高压压制成块剂。经检测自燃温度适中,为132~138℃;点燃试验合格,瞬间发烟,燃烧时间<20 s;成烟率达88.6%。对蚊、蝇、蟑快速杀灭,对大鼠急性吸入毒性LC50>10 000 mg/m3。结论该烟剂对卫生害虫具有良好的杀灭效果,使用便捷,毒性属于微毒级。
Objective To develop a fast insecticide which is efficient, safe, easy to use and reliable in performance. Methods With reference to the relevant national standards, the performance, efficacy and toxicity of the pesticide were tested. Results The insecticidal smoke agent deltamethrin as an active ingredient, supplemented by oxidants, flame retardants and other ingredients high pressure into a block agent. After testing the moderate self-ignition temperature, 132 ~ 138 ℃; ignition test pass, instant fumes, burning time <20 s; smoke rate of 88.6%. Mosquitoes, flies, cockroaches quickly kill rats acute inhalation toxicity LC50> 10 000 mg / m3. Conclusion The smoke agent has a good killing effect on the health pests and is convenient to use. The toxicity belongs to the micro-toxicity level.
