Abstract
The invention discloses a paraquat thickening agent and a preparation method of the paraquat thickening agent. The paraquat thickening agent comprises the following components in parts by weight: 2-5 parts of hydrogenated tallow amine, 20-30 parts of fatty alcohol polyoxyethylene ether, 1-3 parts of sodium sulfate, 1-3 parts of glycine betaine, 3-5 parts of ethoxylated ether amine, 10-20 parts of phosphite ester and 0.02-0.04 part of sodium hydroxide. The preparation method of the paraquat thickening agent comprises the steps of (1) according to the ratio, feeding the hydrogenated tallow amine into the fatty alcohol polyoxyethylene ether, and evenly dispersing; (2) adding the ethoxylated ether amine into the phosphite ester, and evenly dispersing; (3) mixing the product obtained in the step (1) and the product obtained in the step (2), feeding the other components, and evenly mixing and dispersing to obtain the finished product.
Description
Technical field
The invention belongs to insecticides adjuvant technical field, more specifically relate to a kind of paraquat thickener and preparation method thereof.
Background technology
Along with modern, the developing rapidly of chemical industry, each user, to insecticides adjuvant demand growth, constantly promotes insecticides adjuvant thus, the innovation of chemical products and upgrading.Constantly increase at the current population that faces, soil reduces day by day, grain demand sharply, when environmental demand is more and more severeer, people are needed to develop how efficient, safe novel pesticide, and the novel pesticide construction cycle is long, investment is large, risk is high, success rate is low, particularly modern high technology and hyper-active pesticide kind.Along with developing rapidly of agricultural chemicals synergist, numerous novel forms must be had and produce.On the one hand, the physical property of former medicine can be improved, not only extend the service life of original agricultural chemicals, the effect of better performance agricultural chemicals, reduces dosage, expands range of application, reduce costs, save manpower etc., and decreasing pollution can be reached, improve the safety used, play agriculture the effective elements of the medicine object to greatest extent, therefore, exploitation tallies with the national condition and international market demand with exploitation, and to give various agricultural chemicals with active function increases its wetability, permeability, film forming and adhesivity.There is significant economic benefit and social benefit.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, a kind of paraquat thickener is provided.
Another object of the present invention is to the preparation method that this paraquat thickener is provided.
For achieving the above object, this invention takes following technical scheme:
A kind of paraquat thickener, with parts by weight, composed of the following components:
Hydrogenated tallow amine: 2 ~ 5, fatty alcohol-polyoxyethylene ether: 20 ~ 30,
Sodium sulphate: 1 ~ 3, betain: 1 ~ 3, ethoxylated ether amine: 3 ~ 5,
Phosphite ester: 10 ~ 20, sodium hydroxide: 0.02 ~ 0.04.
The preparation method of described paraquat thickener is:
(1) by proportioning, hydrogenated tallow amine is added fatty alcohol-polyoxyethylene ether, be uniformly dispersed;
(2) ethoxylated ether amine is added in phosphite ester, be uniformly dispersed;
(3) by the mixing of the product of step (1) and step (2), and add all the other components, after mixing is uniformly dispersed finished product.
Compared with prior art, the present invention has following beneficial effect:
(1) solve domestic like product drug effect low, have pollution, cost is high, the low inferior problem of preparation level; This product is yellow transparent thick liquid at normal temperatures, soluble in water, has the functions such as excellent wetting, infiltration, thickening, synergy.
(2) on the basis not affecting the original excellent comprehensive performance of paraquat, to environment and ecological close friend and compatibility.
(3) significantly can reduce solution surface tension, stronger penetration, effectively can strengthen the adhesion between drop and liquid level, promote that plant absorbs medicament, increase the conduction of medicament in plant corpus thus improve agent activity.
(4) consumption is few, and adhesivity is good, can reduce paraquat consumption, reduces preparation cost cost; This agent safety non-toxic, environmental protection, in a wide variety of climates equal function admirable.
