Embodiment Construction

[0006] A processing method of high-efficiency paraquat ointment, characterized in that: the formula is water-soluble ointment with paraquat dichloride 30-45% by weight, equivalent paraquat cation content of 21.74-32.58%, surfactant alkyl Glucoside 1-6%, polyisocyanate curing agent 2-8%, carboxymethylcellulose sodium disintegrant 2-13%, special modified polyether 0.5-3%, other additives are emetic, warning color, odor and bittering agent, the rest is water; the processing step is to add water into the reaction kettle after weighing according to the formula, start stirring at low speed, control the temperature at 70°C-80°C, and then add alkyl glucoside and polyisocyanate in turn Curing agent, sodium carboxymethylcellulose disintegrating agent, special modified polyether, after stirring for half an hour, add paraquat mother liquor, add emetic agent, warning color, odorant and bittering agent safety auxiliary ingredients in sequence, and then Add water, keep warm and stir at low s...

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...
