Embodiment 1

[0033] like figure 1 Shown, a kind of low-temperature anti-degradation manufacturing method of small particle size suspending agent comprises the following steps:

[0034] Step 1: adding the original drug to be ground into the jet mill 1, and after the grinding is completed, the original drug powder is obtained;

[0035] Step 2: Transfer the original drug powder obtained in step 1 to the pipeline crushing pump 2, and add auxiliary agents and water, wherein the auxiliary agents can be made of dispersants, wetting agents, thickeners, antifreeze agents, preservatives and One or more components in the defoamer, start the pipeline pulverizing pump 2 to pulverize, after the pulverization is completed, the original drug mixture is obtained, preferably, a screen is also provided between the pipeline pulverizing pump 2 and the sand mill 3 , the pore size of the sieve is less than or equal to 15 microns, that is, the raw drug mixture obtained by pulverization is filtered by a sieve wit...

Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a low-temperature anti-degradation manufacturing method for a small-particle-diameter suspending agent. The present invention includes step 1: adding the original drug to be ground into a jet mill, and obtaining the original drug powder after the grinding is completed; step 2: transferring the original drug powder obtained in step 1 to a pipeline crushing pump, adding auxiliary agent and water, start the pipeline crushing pump for crushing, and obtain the original drug mixture after the crushing is completed; Step 3: transfer the original drug mixture in step 2 to a sand mill for grinding, and sieve after grinding to obtain a suspending agent. The present invention is crushed by a jet mill first, then pulverized by a pipeline pump for the second time, and finally sanded, which effectively reduces the time and frequency of sanding, reduces the temperature of the material after sanding, and reduces the risk of the original drug due to temperature rise. The possibility of degradation and product instability caused by it can also effectively prevent the blockage of the sand mill caused by the original drug being too coarse, and reduce the load of the sand mill.

Description

technical field [0001] The invention belongs to the technical field of pesticide materials, and in particular relates to a low-temperature anti-degradation manufacturing method for a small-particle-diameter suspending agent. Background technique [0002] Chemical pesticides contain a large amount of organic solvents, which have brought serious pollution to the natural environment while making great contributions to agricultural harvests. With the improvement of environmental protection laws and regulations, the call for reducing pesticide pollution is becoming stronger and stronger. It has become the general trend of pesticide development to develop new liquid preparations with high safety, green environmental protection and low price to reduce or eliminate the hazards of organic solvents. Among them, water-based is one of the leading directions for the development of pesticide formulations. This new type of pesticide formulation will also add new features to the pesticide...
