Description
Technical field
The invention belongs to agricultural effervescent granule, relate to a kind of effervescent granule that contains tensio-active agent and its production and application, be mainly used in the use that mixes with pesticide preparation or fertilizer, do not contain pesticide active ingredient, use as the auxiliary agent of pesticide preparation or fertilizer.
Background technology
The object of the present invention is to provide a kind of efficient, dissolving (dispersions) fast in water, stable high agricultural effervescent granule.Another object of the present invention is to provide the preparation method and the application of above-mentioned agricultural effervescent granule.
At agriculture field, pesticide preparation and fertilizer must satisfy the restriction of diversified reality.Except that good desinsection, sterilization, weeding, coordinate plant growth being provided, replenishing the performance such as plant nutrient, they also need to satisfy many physical constraints that surpass these basic demands.For example, preparation back soup or solution should have excellent wetting capacity, perviousness, tackiness, dispersiveness, and well-known, some tensio-active agent can improve performances such as the mixed wettability of pesticide preparation or fertilizer and water, perviousness, tackiness, dispersiveness.In addition, can also make tensio-active agent snap-out release in water by the effervesce characteristic of foaming component, improve the dispersiveness of agricultural chemicals or effective fertilizer composition, this can realize by add two kinds or the above component that produces gas that reacts in water, for example use sodium bicarbonate and citric acid, this also is the common component of effervescent granule, two kinds or above component of reacting are placed in the independent particle, perhaps the two kinds of components that can react are made particle respectively, remix is made finished product, this all is that well-known, such particle is exactly an effervescent granule.
The problem that exists during pesticide preparation or fertilizer are used on agricultural:
1, wettability is poor.The content of the tensio-active agent in pesticide preparation or the fertilizer and kind are all limited, one, be limited by the restriction of active constituent content, perhaps based on the consideration of manufacturing cost aspect, the content of tensio-active agent is lower in product, usually about 5-50%, part highly effective pesticide per hectare consumption is very low, causes the amount of tensio-active agent wherein also to reduce thereupon; And during practical application, extension rate often at 500-5000 doubly, the content of tensio-active agent is lower in soup after the dilution or the solution, it is very limited that it reduces capillary effect, cause soup or solution to target crop wettability, poor permeability, soup or solutions a large amount of in using tumble on the ground, can not play a role, and cause the significant wastage of effective constituent and cause environmental pollution.They are two years old, tensio-active agent in pesticide preparation or the fertilizer will satisfy many-sided demand such as wettability, perviousness, dispersiveness, stability etc., often take two or more different tensio-active agents of performance to use simultaneously, cause the content wretched insufficiency of the good tensio-active agent of wettability.Its three, be limited by the chemical property of effective constituent, the tensio-active agent that some is outstanding, often since its special physico-chemical property can not add in the preparation.As on agricultural, obtaining the organic silicon surfactant of widespread adoption, have the wetting of excellence, infiltration, diffusion, be generally liquid, stablize in neutrality or under near the neutral condition, but in acid or alkalescence or have water to exist to cause organosilicon to decompose under the situation, limited the application of this class tensio-active agent, promptly in some acidity, alkalescence or have in the pesticide preparation or fertilizer product that water exists, can not directly add organic silicon surfactant, therefore in fact often adopt the tensio-active agent form of packing separately, sell with pesticide preparation or fertilizer product companion's mode, perhaps sell separately field mix during use.
2, poor permeability.The quality of penetrating quality depends primarily on the kind and the quantity of tensio-active agent, be limited by the content and the chemical property restriction of agricultural chemicals or effective fertilizer composition equally, many outstanding tensio-active agents or use quantity not sufficient, or because the reason of physicochemical property, can not join in agricultural chemicals or the fertilizer, cause poor permeability.
3, bad dispersibility.For water-fast agricultural chemicals of effective constituent or fertilizer, in use, effect and its dispersed height correlation in water, in general, dispersiveness is good more, and the suspensibility of the effective constituent of agricultural chemicals or fertilizer in water is high more, be more evenly distributed in water, the liquor strength gradient is more little.And the effective constituent of most of agricultural chemicals and part fertilizer are water-fast, perhaps solubleness is not high in water, need to guarantee its dispersion in soup or solution by control particle size and dispersing auxiliary, and the quality of dispersing property depends primarily on tensio-active agent, same reason, because of the add-on deficiency of tensio-active agent, dispersiveness is usually bad in pesticide preparation or the fertilizer product.
4, had on the market independent based on the pesticide preparation of tensio-active agent or the auxiliary agent of fertilizer, as common organic silicon surfactant, and the conventional surfactant that contains the alkylphenol polyoxyethylene class, adopt the liquid pouch-packaged, because of its good wetting, penetrating quality, obtained market achievement preferably.But there is following defective in this series products:
(1) because tensio-active agent mostly is liquid or paste, be difficult to be processed as solid preparation, small part is processed into powdery, and dust from flying in the time of processing and use has caused bigger pollution to environment, has limited its application on agricultural chemicals or manure solids preparation.
(2) be powdery and granulous agricultural chemicals and fertilizer product for outward appearance, during production, liquid surfactant is difficult to directly join wherein, promptly allow to add, because Technology, add-on is often on the low side, because add a large amount of tensio-active agents, can cause product appearance not good, for example mobile variation, product become sticky, problems such as dispersing property is poor, caking.
Agricultural effervescent granule of the present invention promptly contains the effervescent granule that helps out that is applied to pesticide preparation or fertilizer of tensio-active agent, does not see related products and report.
At the problems referred to above, the applicant has developed agricultural effervescent granule.Add in the preparation (granular, powdery) of solid pesticide preparation (granular, powdery) or solid fertilizer; Add effervescent granule of the present invention when perhaps using in the field separately, existing mixing now used.The soup or the solution of preparation have good wettability, and perviousness, tackiness and plate-out ability play synergism, improved the utilization ratio of effective constituent, reduced waste and to the pollution of environment, had tangible performance, cost and environment-friendly advantage, its market application foreground is very wide.
