Embodiment 1

[0017] Preparation of 10-60nm, 22% Nano Copper Hydroxide Mixed Raw Powder

[0018] After selecting the control agent medium to be pulverized in advance, it is added to the copper salt in a mass ratio of 2:1 to the solid phase product copper hydroxide for mixing and pulverization; at the same time, another solid phase reactant is pulverized and sieved; the two solid phase reaction raw materials , The particle size of the control agent is controlled at 325-1250 mesh. After mixing the two reaction mixtures uniformly with a mixer, control the reaction temperature and reaction speed. After the reaction is completed, place it in a constant temperature water bath box and treat it at 40°C for 6-10 hours to obtain the mixed raw powder of nano-copper hydroxide. %, the yield is 92%.

Embodiment 2

[0020] Preparation of 50-100nm, 30% Nano Copper Hydroxide Mixed Raw Powder

[0021] After selecting the control agent medium to be pulverized and screened in advance, it is added to the copper salt in a mass ratio of 1:1 to the solid phase product nano-copper hydroxide for mixing and pulverization; at the same time, another solid phase reactant is pulverized and screened; the solid phase The particle size of the reactant and the control agent are all controlled at 325-1250 mesh. After mixing the two reaction mixtures evenly with a mixer, control the temperature and reaction speed, place them in a constant temperature water bath after the reaction, and treat them at a temperature of 80°C for 6 to 10 hours to obtain 30% nano-copper hydroxide mixed raw powder. Wherein the particle size distribution of nanometer copper hydroxide is 50-100nm, and the yield is 94%.

Abstract

The invention relates to a solid-phase synthesized method for nanometer cupric hydroxide bactericidal agent technical powder, which belongs to the technical field of the application of nanometer material, and utilizes inert medium control solid-phase reaction nucleation rate to prepare nanometer cupric hydroxide technical powder, and the invention is characterized in that the medium control is the nuclear portion of the invention, and the manufacturing art is simple. The process of the solid-phase synthesized art comprises selecting appropriate control medium and solid-phase reactant according to the formulation of wettable powder, and respectively breaking and screening, positioning control agent and the product yield of the reaction cupric hydroxide with the weight ratio (0.5-2):1 in nantokite, calculating solid-phase reactant according to the chemical measuring, positioning in a water bath case for a plurality of hours after slowly grinding to be even under the indoor temperature, and attaining the nanometer cupric hydroxide power body after the reaction is completed. The micro-nano power body is suitable to be used as technical powder of agricultural chemical bactericidal agent products such as wettable power agent, soluble power agent, dry suspending agent and suspending agent and the like.

Description

technical field [0001] The invention discloses a solid-phase synthesis method of nano copper hydroxide fungicide raw powder, which belongs to the technical field of nano material application. Background technique [0002] In the past two decades, my country's agricultural planting level has developed rapidly and long-term. At the same time, plant fungal diseases have also begun to break out on a large scale. Especially in the highly intensive off-season vegetable, fruit and flower growing areas, the continuous occurrence of serious fungal diseases has brought huge economic losses to farmers. In 2000, the return of exports due to excessive pesticide residues in products caused economic losses as high as 9.6 billion U.S. dollars, and the losses in 2001 and 2002 exceeded 10 billion U.S. dollars. The Ministry of Agriculture launched the "Non-Pollution Food Action Plan" in April 2001. It can be seen that the development and development of high-efficiency and low-residue pollutio...
