Abstract
The invention discloses a kind of oil-suspending agent auxiliary agent.With parts by weight, the present invention is composed of the following components: vegetable oil acid: 8 ~ 12, nonyl phenol: 8 ~ 12, castor oil acid: 8 ~ 12, polypropylene: 30 ~ 40, oxirane: 40 ~ 60, KOH:0.3 ~ 0.4, acetic acid: 0.2 ~ 0.3.Preparation method of the present invention, comprise following technical step: (1) drops into vegetable oil acid, nonyl phenol and castor oil acid in the 1L reactor that thermometer, agitator and chuck are housed, 120 DEG C ,-0.97Mpa dehydrated under vacuum 1.5 hours, then use N
2replace 3 times; (2) detect moisture qualified after, in reactor, polypropylene and acetic acid is passed into when 115 DEG C, when the temperature in still rises and with passing into after oxirane (3) led to during pressure drop continuously, aging 1.5 little after normal pressure in 120 DEG C of insulations, vacuumize, discharging, add KOH and neutralize to obtain finished product.
Description
Technical field
The invention belongs to insecticides adjuvant technical field, more specifically relate to a kind of oil-suspending agent auxiliary agent and preparation method thereof.
Background technology
Insecticides adjuvant is the general name to the various adjuvants used outside active ingredient in chemical pesticide processing formulation.Auxiliary agent itself does not have biologically active, but is indispensable additive in form formula or in dispenser, add the main purpose of auxiliary agent be improve drug effect, reduce the consumption of agricultural chemicals, cost-saving, reduce agricultural chemicals to the pollution of environment.Auxiliary agent to the synergistic effect of agricultural chemicals especially weed killer herbicide mainly by increase agricultural chemicals plant surface hold-up, extend be detained time ask and improve the penetration capacity to plant epidermis.Because the kind of auxiliary agent is different, its mechanism of action is also different.In use, be many with surfactants such as emulsifier, profit spreaders, purposes is comparatively wide, also larger on powder performance impact.Adding of surfactant, greatly reduce the surface tension of solution, make the drop of medicament emulsion surface form the strong diaphragm of one deck, strengthen medicament at wetting, the spread of plant surface or insect body surface and adhesive force, thus improve drug effect.Be applied to mainly containing of pesticide surfactant at present: aliphatic alcohol polyethenoxy class, polyoxyethylene alkylphenol ether class, Sulfonates, sulfonic acid esters, amide-type, silicone based etc.
Vegetable oil type suspending agent be with vegetable oil if soybean oil, rapeseed oil, cottonseed wet goods are for carrier, pulverized by sand milling, make active ingredient form suspension in oil phase.This kind of formulation meets the requirement of environment-friendly type preparation: the first, using pure natural plant oil as main carriers, equally have stronger Environmental compatibility with aqueous formulation; The second, vegetable oil and target have stronger affinity, can give full play to the preventive and therapeutic effect of active ingredient, compared with aqueous formulation, without the need to adding a large amount of synergist to improve the function of preparation; Three, having very strong adaptability, is important supplement that is water base, granular preparation, can make manyly to make this dosage form product to the more sensitive agricultural chemicals of water; Four, because it has higher flash-point and well safety, very suitable to some spray agents, as low capacity (LV), ultra low volume spraying preparation (ULV) etc., not easily produce the drug injury problem that organic solvent often occurs in use; Five, be a kind of renewable resources, raw material is easy to get, and auxiliary dosage is few, advantage of lower cost.Domestic market vegetable oil resource is sufficient, has certain competitive advantage compared with the aromatic solvent such as toluene, dimethylbenzene.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, a kind of oil-suspending agent auxiliary agent is provided.
Another object of the present invention is to the preparation method that this oil-suspending agent auxiliary agent is provided.
For achieving the above object, this invention takes following technical scheme:
A kind of oil-suspending agent auxiliary agent, with parts by weight, composed of the following components:
Vegetable oil acid: 8 ~ 12, nonyl phenol: 8 ~ 12, castor oil acid: 8 ~ 12,
Polypropylene: 30 ~ 40, oxirane: 40 ~ 60,
KOH:0.3 ~ 0.4, acetic acid: 0.2 ~ 0.3.
The preparation method of described oil-suspending agent auxiliary agent is: in the 1L reactor that thermometer, agitator and chuck are housed, drop into vegetable oil acid, nonyl phenol and castor oil acid, and 120 DEG C ,-0.97Mpa dehydrated under vacuum 1.5 hours, then use N
2replace 3 times, after detection moisture is qualified, when 115 DEG C, in reactor, pass into polypropylene and acetic acid, rise when the temperature in still and pass into oxirane continuously with during pressure drop, after lead to, being incubated in 120 DEG C aging 1.5 little after normal pressure, vacuumize, discharging, add KOH and neutralize to obtain finished product.
Compared with prior art, the present invention has following beneficial effect:
The present invention utilizes vegetable oil oleic acid to do initiator and epoxides to carry out ring-opening reaction and obtain monomer, then carries out composite obtained auxiliary agent with other surfactants.This Additives Products is using pure natural plant oil as main carriers, equally have stronger Environmental compatibility with aqueous formulation, vegetable oil and target have stronger affinity, can give full play to the preventive and therapeutic effect of active ingredient, compared with aqueous formulation, without the need to adding a large amount of synergist to improve the function of preparation.This auxiliary agent also has in addition very strong adaptability, is important supplement that is water base, granular preparation, can make manyly to make this dosage form product to the more sensitive agricultural chemicals of water.The most important thing is that its raw material raw material is easy to get, auxiliary dosage is few, advantage of lower cost.
The present invention is pollution-free, consume excessively without water power, uses simple and reduces preparation cost, having good properity and price advantage.
The present invention is yellow to buff thick liquid at normal temperatures, and with environmental friendliness, have higher economic benefit, social benefit and ecological benefits, popularizing application prospect is wide.
