Smoke agent

Abstract

The invention relates to a smoke agent. The smoke agent comprises following components in parts by weight: 5-25 parts of potassium nitrate, 5-30 parts of an aerial fog density modifier, 5-15 parts of ammonium chloride, 20-55 parts of a surfactant, 0.1-1.5 parts of a fire retardant, 5-20 parts of urea and 1-15 parts of talcum powder. The smoke agent provided by the invention is added with the fire retardant, so that the difficulty in combustion is realized; the fire potentials can be eliminated in use; pesticides have good compatibility and high use ratio; no pollution on environment can be realized.

Description

technical field [0001] The invention relates to a smoke generator and belongs to the technical field of pesticide products. Background technique [0002] Smokers can be divided into solid and liquid according to their form. Solid fuming agents mainly include hexachloroethane-zinc oxide mixture, crude anthracene-ammonium chloride mixture, yellow phosphorus, red phosphorus, etc. Liquid fuming agents mainly include high-boiling point petroleum, coal tar, metal-containing polymers, sulfur trioxide-chlorosulfonic acid mixture, and titanium tetrachloride. In addition, there are colored smoke agents, which produce brightly colored smoke screens. [0003] In places where it is inconvenient to spray pesticides, people usually use pesticide fume generators to repel insects and kill insects on crops; without special treatment, traditional pesticide fume generators have low smoke density and drift with the wind, which cannot completely enter designated areas, causing At the same time...

Problems solved by technology

[0003] In places where it is inconvenient to spray pesticides, people usually use pesticide fume generators to repel insects and kill insects on crops; without special treatment, traditional pesticide fume generators have low smoke density and drift with the wind, which cannot completely enter designated areas, causing At the same time of waste, it also pollutes the air and the environment in other areas. In addition, the poor compatibility of traditional fuming agents and pesticides leads to unevenness, which in turn reduces the insecticidal effect. The composition of fuming agents has a low boiling point and is flammable. fire hazard
