Abstract
The invention relates to a plant growth regulator preparation technology, in particular to a paclobutrazol suspending agent and a preparation technology thereof, is suitable for the pesticide preparation preparing technology and belongs to the technical field of chemicals. In China, paclobutrazol is oriented to the market mainly in the form of 15% wettable powder. Due to the fact that the wettable powder is prone to dust pollution in the processing and using processes and the suspending rate of the wettable powder is lower than that of a suspending agent, products are prone to phytotoxicity. A paclobutrazol technical material, a wetting agent, a dispersing agent, a thickening agent, an antifoaming agent, an antifreezing agent, a preservative and other substances are adopted and prepared into the paclobutrazol suspending agent according to a certain weight percentage through a specific preparation method. The paclobutrazol suspending agent has the advantages of being capable of being uniformly mixed with water in any proportion and dispersed, good in fluidity, free of influences of water quality and water temperature, convenient to use, not prone to environmental pollution and capable of being sprayed directly or after dilution.
Description
Technical field
The present invention relates to a plant growth regulators manufacturing technology, especially Paclobutrazol suspension concentrate and manufacturing technology thereof, belong to chemical technology field.
Background technology
The formulations of pesticide that agricultural chemicals suspension agent is prepared through soybean dietary fiber by water insoluble solid pesticide, insecticides adjuvant (wetting agent, dispersant, thickening agent, defoamer, antifreezing agent, preservative etc.) and water.The advantage of this dosage form is can uniformly to mix dispersion with water arbitrary proportion, not by water quality, Water Temperature, easy to use, is difficult to pollute environment, the preferable dosage form that can directly or spray after dilution.Suspending agent is that domestic and international pesticide industry generally acknowledges " environment-friendly type " novel form.The exploitation of this one dosage type low temperature, gives production and the application of the solid pesticide being insoluble in water and organic solvent, has started vast potential for future development, and had the strongest competitiveness.Suspending agent has become as the most competitive novel form in China's pesticidal preparations.
Paclobutrazol is a plant growth regulators.Have and delay plant growing, suppression cane elongation, shorten internode, promote plant tillering, increase plant stress-resistance performance, improve the effects such as yield.Paclobutrazol mainly meets the needs of the market with 15% wettable powder at home.Owing to wettable powder easily produces dust pollution when processing and use, the suspensibility of wettable powder is lower than suspending agent in addition, and product is easily generated poisoning.Therefore, along with the enhancing of people's environmental consciousness, and the needs of modern agricultural development, develop safe and efficient pesticides new formulation meaning particularly significant.Owing to suspending agent wet method is processed, do not produce dust, be to replace organic solvent with water, being suitable for environmental requirement, product granularity is thinner than wettable powder in addition, and effective ingredient dissipates uniformly, suspensibility is high, and drug effect is higher than wettable powder, is the most more satisfactory environmental protection novel form.
Summary of the invention
In order to solve the problem that people, domestic animal and environment are easily worked the mischief by existing wettable powder, the present invention provides a plant growth regulators manufacturing technology.
The technical scheme is that and be achieved in that: it is made up of the former medicine of paclobutrazol, wetting agent, dispersant, thickening agent, defoamer, antifreezing agent, preservative, the percentage by weight of the most each component is: the former medicine of paclobutrazol 20～30%, wetting agent 0.5～10%, dispersant 0.5～10%, thickening agent 0.1～5%, defoamer 0.1～5%, antifreezing agent 1～10%, preservative 0.1～10%, surplus is water.Wherein: one or more in aliphatic alcohol sulfate, a alkene sulfonate, dialkyl group succinate sulfonate sodium, fatty alcohol, alkylphenol polyoxyethylene succinic acid half sulfonated ester, fatty acid amide N N-methyltaurine sodium salt, alkylphenol polyoxyethylene sulfate, Negel, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether of wetting agent；One or more in fatty alcohol ether phosphate ester, nonyl phenol ether phosphate, triphenoethyl benzene phenol polyethenoxy ether, phosphate ester triethanolamine salt of dispersant；One or more in dispersant preferred fat alcohol sulfate, fatty acid amide N N-methyltaurine sodium salt, fatty alcohol, alkylphenol polyoxyethylene succinic acid half sulfonated ester；One or more in dispersant preferred fat alcohol ether phosphate, nonyl phenol ether phosphate, phosphate ester triethanolamine salt.The suspending agent using above-mentioned wetting agent and dispersant composition has the dispersibility and mobility increased；One or more in arabic gum, Xanthan gum, methylcellulose, carboxymethyl cellulose, hydroxyethyl cellulose, sodium acrylate, polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl acetate, gaseous silicon oxide, Magnesiumaluminumsilicate of thickening agent；One or more in organosilicon ketone, the fatty alcohol of C8～10, C10～20 representative examples of saturated aliphatic carboxylic and esters, ester one ether type compound of defoamer；One or more in ethylene glycol, propylene glycol, glycerol, diethylene glycol, 2,2'-ethylenedioxybis(ethanol)., Polyethylene Glycol, monoethylin diglycol, methyl trimethylene diglycol, carbamide, ammonium sulfate, citric acid of antifreezing agent；Preservative is selected from formaldehyde or paraformaldehyde.
The present invention is by former for a certain amount of paclobutrazol medicine, wetting agent, dispersant, thickening agent, defoamer, antifreezing agent, preservative and water, repeatedly circulating waterproof pulverization with sand mill to fineness of the particles is 1～5 m, then with homogenizer carry out homogenizing, thickening, froth breaking are prepared from.
It is an advantage of the invention that and can uniformly mix dispersion with water arbitrary proportion, good fluidity, not by water quality, Water Temperature, easy to use, it is difficult to pollute environment, can directly or spray after dilution.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Paclobutrazol former medicine 20kg, aliphatic alcohol sulfate 2.5kg, alkylphenol polyoxyethylene succinic acid half sulfonated ester 2.5kg, methylcellulose 0.5kg, organic silicon defoamer 0.05kg, ethylene glycol 5kg, paraformaldehyde 0.05kg, remaining supply 100kg with water, repeatedly circulating waterproof pulverization with sand mill to fineness of the particles is 1～5 m, carry out homogenizing the milky suspending agent product i.e. made with thickening, froth breaking with homogenizer again, record paclobutrazol content be 20.2%, suspensibility be 94%.
