Abstract

The invention provides a processing method of high-efficient paraquat paste. The paste comprises, by weight percent, 30-45 % of paraquat dichloride salt, being equivalent to 21.74-32.58 % of paraquat cation, 1-6 % of a surfactant alkyl glycoside, 2-8 % of a polyisocyanates curing agent, 2-13 % of a carboxymethylcellulose sodium disintegrating agent, 0.5-3 % of special modified polyether, and the balance being auxiliary agents and water. The finish product is prepared by heating, insulating and stirring. The product has an appearance of dark blue paste, does not flow at a normal temperature, can not only effectively prevent splashing of the paraquat paste to burning skins of human or animals, but also be low in amount of wrong or impulsive swallow because of low fluidity, thereby substantially improving safety of the paraquat and being convenient to transport; and the product can be relatively rapidly dispersed and dissolved, is free of precipitate during standing and substantial in using efficacy.

Description

technical field

[0001] The invention relates to a processing method of high-efficiency paraquat ointment. Background technique

[0002] At present, paraquat is the second largest herbicide in the world herbicide market and has been registered for use in more than 100 countries. Paraquat is a quick-acting contact herbicide, which can act quickly after spraying, and quickly inactivate after contacting the soil, leaving no residue in the soil. Under normal use, it is harmless to wild animals and the environment, and correct use has no adverse effects on the health of spraying workers. In developed and developing countries, paraquat is widely used on a variety of crops, contributing to the improvement of agricultural productivity. However, when paraquat preparations enter the body from the mouth in excess of a certain amount, the damage to the gastrointestinal tract, liver, kidney, heart, and lung can be life-threatening. According to reports, in recent years, the trend of...
