Description
[technical field]
The aerosol, particularly a kind of smoke agent specially used for thermal smoke sprayer that the present invention relates to a kind of aerosol base-material and prepared by this base-material.
[technical background]
The operation principle of the fog machine of use is in the market: the air-flow that produces HTHP by fuel combustion is gasificated into steam with agricultural chemicals and farm chemical carrier (aerosol) by HTHP, is sprayed at crop surface.The carrier of these agricultural chemicals is all to make aerosol by emulsifier, in other words by emulsifier directly as aerosol, emulsifier belongs to organic matter, it is processed with diverse ways by the different surfaces activating agent by various greases (as: vegetable oil, mineral oil), with emulsifier directly as aerosol as carrier with crops one are packaged enters the fog machine dispenser and produced very large drawback and defective.The first, emulsifier is a kind of grease, is contained in the central heat of meeting of fog machine easily on fire, can not be used for desinsection and the sterilization of forest at all, and this has just limited the scope of application of heating power fogging machine.The second, the dispenser cost is high, and in the dispenser process, all use is emulsifier stoste, because the emulsifier temperature raises, the loss amount increase causes the wasting of resources, simultaneously, has caused environmental pollution because emulsifier content in atmosphere increases.Three, emulsifier liquefies by HTHP and just easily swims in air, and the medicine molecule can not rest on crop surface effectively, for a long time in being brought into air, shortened the affine time of medicine and insect pest, caused the waste of medicine, insect pest can not effectively be killed, inefficiency.
Utilize on the market diesel oil as solvent, most typically be, commercially available emulsifiable concentrates for agricultural chemicals is blended into diesel oil as aerosol, then what also have uses in diesel oil with pesticide original medicine " molten ", etc.The aerosol of preparation mainly contains following defective like this: the one, and diesel oil and medicament are immiscible, are prone to layering, thereby reduce drug effect; The 2nd, the flash-point of diesel oil is low, and burning-point is low, easily catches fire; The 3rd, easily produce colloid in aerosol spraying mist process, block machine, fog machine is broken down and difficult the startup.
[summary of the invention]
The objective of the invention is to overcome in prior art not enoughly, provide that a kind of safety, environmental protection, efficient, low toxicity, pollution are little, a kind of heating power fogging machine special environment protection aerosol of low-residual.
Its component of smoke agent specially used for thermal smoke sprayer base-material that the present invention relates to comprises flash-point 〉=80 ℃, 40 ℃ of viscosity≤25mm
2The mineral oil of/s and surfactant (comprising anionic, nonionic, cationic or its compound), its content (percentage by weight) and preferred value are as follows:
Mineral oil (preferably select and take off fragrant solvent naphtha): (preferred value is 85-93% to 70-95%; );
Surfactant (preferably selecting non-ionic surface active agent): 5-30% (preferred value is 7-15%).
Above-mentionedly take off fragrant solvent naphtha, the preferred value of its flash-point is between 80-100 ℃.
Above-mentioned nonionic surface active agent can be polyoxyethylene nonylphenol ether series of products, fatty alcohol-polyoxyethylene ether series of products, these Pan's series of products, one or more compounds of tween series of products.
Another kind of the present invention has the aerosol base-material of antirust function, and its component comprises flash-point 〉=80 ℃, 40 ℃ of viscosity≤25mm
2The mineral oil of/s, surfactant and antirust agent, the content of each component is as follows:
Mineral oil (preferably select and take off fragrant solvent naphtha): 80-93% (preferred value is 83-92%);
Surfactant (preferably selecting non-ionic surface active agent): 5-15% (preferred value is 6.0-12%);
Antirust agent: 0.5-5.0% (preferred value is 1.0-4.0%).
Smoke agent specially used for thermal smoke sprayer base-material of the present invention can be made aerosol according to following formula in use:
Base-material: 45-55% (preferred value is 46-53%);
Water: 43-50% (preferred value is 44-47%);
Emulsifiable concentrates for agricultural chemicals or wetting powder: 1.0-10% (preferred value is 3.0-7.0%).
In concrete spray pharmaceutical worker does, produce heat by the gasoline pulse-combustion aerosol is gasificated into smog, medicine mist particle is less than 50 microns, fill the air, spread and float to fruit tree, vegetables and other crops surface and institute and have living space, form with liquid particle is evenly adsorbed plant surface, thereby plays the effect of prevention and elimination of disease and pests.
Advantage of the present invention is as follows;
1. use safety.
The flash-point of aerosol carrier is greater than 80 ℃, and burning-point is high, wherein adds certain water gaging, reduces the aerosol atomization temperature, can flame, use safe and reliable.
2. environmental protection.
Take off fragrant solvent naphtha for low aromatic hydrocarbons, low-sulfur, nontoxic, tasteless feature of environmental protection solvent, to pollution-free damages such as woods fruit, forest, vegetables and other crops.The non-ionic surface active agent emulsifier has gentleer, acid-fast alkali-proof performance, improves that medicament adheres to, infiltration and solvability.
3. aerosol resistance of rainwater washing against ability is strong.
Due to the non-ionic surface active agent emulsifier, have gentleer, acid-fast alkali-proof performance, improve that medicament adheres to, infiltration and solvability, smog has high plate-out ability and tack on woods fruit, forest, vegetables and other crops etc., medicine drips rapidly secure bond and is being subjected to the medicine surface, difficult drop-off.
4. emulsifiable concentrates for agricultural chemicals or wetting powder can use.
Because part is taken off fragrant solvent naphtha and water, under the efficient emulsifier effect of nonionic, form emulsion due to emulsifiable concentrates for agricultural chemicals or wetting powder, not stratified in 2 hours.
5. environmental pollution is little, and dosage reduces, and effect is high.
After smog is executed, diffusion is immediately filled the air and is attached to plant surface, can be lost in soil hardly, adopts conventional spray-on process, approximately has the droplet of 40-60% to run off, contaminated soil.Use the fog machine prevention and elimination of disease and pests per hour can spray 15-20 mu of ground, can improve more than 20 times than routine spraying effect.Because aerosol is moisture less, can save a large amount of water sources, be used for water scarcity forest zone extermination of disease and insect pest effect better.
6. applied widely.
The medium long-stalked crops such as the cotton of agricultural crops, corn, wheat, the economic crops such as matrimony vine, tea place, Chinese chestnut, grape, orchard, the Pesticidal and sterilizing such as forest, grassland, green house, urban sanitation, sewer, warehouse harbour, public place and prevent and treat large tracts of land locust disaster.
