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
The present invention relates to a kind of processing method of efficient paraquat paste.
Background technology
At present, paraquat is the second largest herbicide on the weed killer herbicide market, the world, has registered in more than 100 countries and has used.Paraquat is the quick-acting type weed killer herbicides that go out that touch, and can play a role rapid inactivation behind the contact soil, noresidue in soil after the sprinkling very soon.Under the normal operating position wildlife and environment are not had harm, correct use has no adverse effects to spraying operation personnel's health.In developed country and developing country, paraquat is used in various crop widely, has promoted the raising of agricultural productive force.But paraquat preparation from mouth, enter in the body surpass a certain amount of after, but can be to the equal threat to life of the detrimental effect of intestines and stomach, liver, kidney, the heart, lung.It is reported that in recent years, paraquat increases to some extent as the trend of suicide medication, and the splash skin of the easy calcination mankind or animal of paraquat preparation.Therefore, take the generation that paraquat is committed suiside in order to reduce, adding causes leaf agent, malodorant, colloid formation agent etc. in the product of paraquat, but effect and not obvious.
Country will forbid the paraquat aqua product in 2014, and our unit, then can effectively reduce dose and be difficult for splashing the calcination mankind or animal if paraquat is made paste by research.But what do that paste making agent faces most critical is the interpolation of auxiliary agent, will make that not only paraquat becomes paste, but also will consider in use, and it is fast to go into aqueous dispersion, can dissolve the medication good effectiveness.
Summary of the invention
Purpose of the present invention is exactly the processing method that a kind of efficient paraquat paste will be provided, and it can overcome the above defective that existing product exists.The object of the present invention is achieved like this, and a kind of processing method of efficient paraquat paste is characterized in that; Its prescription is paraquat two villaumite 30-45% for water-soluble paste by weight percentage, amounting to paraquat cation content is 21.74-32.58%, surfactant alkyl glycoside 1-6%, polyisocyanate curing agent 2-8%, sodium carboxymethylcellulose disintegrant 2-13%, special modified polyethers 0.5-3%, other auxiliary agent is emetic, warning colouration, stink agent and bitters, and all the other are moisture content; Its procedure of processing is for after weighing by prescription, in reactor, add water earlier, start stirring, low speed, the control temperature is at 70 ℃-80 ℃, add alkyl glycoside, polyisocyanate curing agent, sodium carboxymethylcellulose disintegrant, special modified polyethers successively, after stirring half an hour, add the paraquat mother liquor, add emetic, warning colouration, stink agent and the auxiliary composition of bitters safety after adding successively, add water then, continue the insulation stirring at low speed and can get finished product after one hour, finished product loads 200kg or every with every big mouthful Galvanized Iron Drum and moulds a bag paper web loading 50kg and pack.
Product appearance of the present invention is the navy blue paste, and normal temperature does not have flowability.Dispersing and dissolving faster in water, leaving standstill does not have precipitation.Paraquat is processed into paste, not only can effectively avoid the paraquat preparation skin of the calcination mankind or animal that splashes, and can be low because of flowability, wrongly take or the impulsion property amount of swallowing low, significantly improved the safety of paraquat, it is more convenient to transport, and uses drug effect remarkable.
Embodiment
A kind of processing method of efficient paraquat paste is characterized in that; Its prescription is paraquat two villaumite 30-45% for water-soluble paste by weight percentage, amounting to paraquat cation content is 21.74-32.58%, surfactant alkyl glycoside 1-6%, polyisocyanate curing agent 2-8%, sodium carboxymethylcellulose disintegrant 2-13%, special modified polyethers 0.5-3%, other auxiliary agent is emetic, warning colouration, stink agent and bitters, and all the other are moisture content; Its procedure of processing is for after weighing by prescription, in reactor, add water earlier, start stirring, low speed, the control temperature is at 70 ℃-80 ℃, add alkyl glycoside, polyisocyanate curing agent, sodium carboxymethylcellulose disintegrant, special modified polyethers successively, after stirring half an hour, add the paraquat mother liquor, add emetic, warning colouration, stink agent and the auxiliary composition of bitters safety after adding successively, add water then, continue the insulation stirring at low speed and can get finished product after one hour, finished product loads 200kg or every with every big mouthful Galvanized Iron Drum and moulds a bag paper web loading 50kg and pack.During concrete enforcement, add materials according to the metering of 1000kg finished product, in the 1500L reactor, add 100kg water earlier, start stirring, low speed, the control temperature is at 70 ℃-80 ℃, add alkyl glycoside 10-60kg, and then adding polyisocyanate curing agent 20-80kg, sodium carboxymethylcellulose disintegrant 20-130kg, special modified polyethers 5-30kg, add paraquat mother liquor 550-650kg after stirring half an hour, add emetic 0.5-5kg after adding successively, warning colouration 0.1-1.5kg, stink agent 0.1-2kg and the auxiliary composition of bitters 0.1-1.5kg safety, water is supplied 1000kg then, continues the insulation stirring at low speed and can get finished product after one hour.
