Abstract
The invention discloses colloidox antiseptic which belongs to the antiseptic technology in the plant protecting field. The compound of the invention includes the weight proportions that: copperchloride is 10-85 percent, wetting agent is 1-15 percent, dispersant is 1-12 percent, disintegrating agent is 8-26 percent, thinner is 10-50 percent, and adhesive is 2-20 percent. After the components are mixed in a certain proportion evenly, after being milled and smashed, head powder is produced. After the head powder is mixed with gelling agent evenly, through grains-making, drying, and screening, the copperchloride water dispersible granules are produced. The invention can overcome the shortage of the copperchloride wettable powder, can lower the using cost for farmers, and can lower the pollution to the environment. When being used, the invention has the advantages that the content is high, the disintegration is quick, the dispersancy is excellent, the storage and the transportation are convenient, the stability is high, the activity is high, the efficiency is good, and the safety is high.
Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, particularly a kind of have the Cupravit water dispersible granules that prevents and treat double action to crops, the invention still further relates to the preparation method of this disinfectant use in agriculture.
Background technology
At present, disinfectant use in agriculture is a lot, and Cupravit is one kind of.Cupravit (english common name: copper oxychloride), chemical molecular formula: can stick to the plant corpus surface after Cu4C12H606) copper oxychloride is sprayed onto on the crop, form layer protecting film, be difficult for by rain drop erosion.Under certain damp condition, discharge solubility basic copper chloride ion and play bactericidal action, be mainly used in the control citrus ulcer, also can be used for preventing and treating other fungal disease and parts of fine fungus diseases.The technical characterstic of this product is that fungicidal spectrum is wide, curative effect height, non-resistant, environmentally safe has obvious passivation and preventive and therapeutic effect to bacterium and part fungal disease, therefore, use Cupravit to prevent and treat disease and should grasp in the disease beginning and see that the phase carries out, just can obtain effect preferably.Drug effect phase of Cupravit is short, and at solar radiation and to absorb airborne water decomposition very fast, about 7 days of its residual effect phase, it has bactericidal activity height, security performance is good, fungicidal spectrum is wide characteristics.But the former powder of Cupravit is made generally in wetting powder and uses in using at present.Because wetting powder dust pollution in processing and use is serious, and environment and health are had very big danger, and shortcomings such as effective rate of utilization is low, lasting period weak point, therefore be the formulation that falls behind and be on the verge of to eliminate relatively in the present formulations of pesticide.
Summary of the invention
The technical problem to be solved in the present invention is to have environmental pollution in the prior art in order overcoming, to be detrimental to health and shortcoming such as use cost height and a kind of high-load of developing environment-friendly type, availability height, and Cupravit water dispersible granules easy to use.
In order to solve the problems of the technologies described above, the present invention realizes as follows: Cupravit water dispersible granules of the present invention comprises Cupravit, wetting agent, dispersant, disintegrant, thinner, six kinds of components of binding agent; The percentage that various components account for gross weight by weight is:
Cupravit accounts for 10%~85%
Wetting agent accounts for 1%~15%
Dispersant accounts for 1%~12%
Disintegrant accounts for 8%~26%
Thinner accounts for 10%~50%
Binding agent accounts for 2%~20%
Described wetting agent is one or more in sodium alkyl benzene sulfonate, alkylsulfonate, alkyl phosphoric acid sodium, alkylphenol-polyethenoxy base sodium sulphate, sodium alkyl sulfate, the Negel.
Described dispersant is one or more in sodium lignin sulfonate, polycarboxylate, diatomite, the Fluhyzon formaldehyde condensation products.
Described disintegrant is one or more in ammonium sulfate, white carbon, attapulgite, the starch.
Described thinner is one or more in precipitated calcium carbonate, diatomite, the kaolin.
Described binding agent is one or more in No. 54, the denaturated sodium polyacrylate, No. 72, polyethylene glycol, No. 3, modified polyvinyl alcohol, lignin.
The preparation method of Cupravit water dispersible granules of the present invention is undertaken by following step:
(1) Cupravit, wetting agent, dispersant, disintegrant, thinner are mixed in proportion;
(2) after carrying out ultra-fine grinding with above mixture, airslide disintegrating mill obtains female powder;
(3) the female powder that obtains after the ultra-fine grinding is mixed by prescription and binding agent;
(4) above mixture is carried out granulation on comminutor;
(5) above shot-like particle is dried;
(6) shot-like particle with oven dry promptly obtains the Cupravit water dispersible granules after sieving.
Good effect of the present invention is as follows: the Cupravit water-dispersible granules that adopts prescription of the present invention to process, its implementation result show that this product has good dispersiveness, and disintegration rate is fast, and disintegration time is less than 3mil; Heat storage stability is good, and the height of adhesion rate in use, lasting period are long, use in production application, the bactericidal potency height the results showed, control efficiency such as canker to multiple kinds of crops all can reach more than 80%, safety is good, and crops are not had poisoning, and packing is simple, storing is convenient, belongs to science environmental protection formulation product.
