The main solvent is one or two of polyethylene glycol 200, polyethylene glycol 300, ethylene glycol, glycerol, propylene glycol, ethylene glycol monobutyl ether and ethanol. Because the special dissolving and emulsifying mode is used, the xanthan gum is uniformly dispersed or dissolved in the system, and the xanthan gum can be rapidly and uniformly dispersed by adding water, so that the agglomeration phenomenon is avoided, the solvent of the xanthan gum can be rapidly prepared, and the preparation time of the solution of the xanthan gum is reduced.
Description
Technical Field
The invention relates to the technical field of yellow-element glue, in particular to a yellow-element glue solvent and a preparation method thereof.
Background
In processing pesticide suspension products, thickeners are commonly added to increase the viscosity of the dispersion, typically in amounts of 0.2% to 5%. The proper viscosity is an important factor for ensuring the quality and application of the pesticide suspending agent. In the selection of the thickener of the pesticide suspension concentrate, xanthan gum solution has the characteristic of low concentration and high viscosity (the viscosity of 1% aqueous solution is equivalent to 100 times of gelatin), and thus xanthan gum is a thickener frequently used in the preparation of the pesticide suspension concentrate.
Xanthangum (English: Xanthangum, transliterated as xanthan gum), commonly known as zein gum and xanthan gum, is a complex polysaccharide produced by fermenting saccharides (glucose, sucrose and lactose) with Xanthomonas campestris (en: Xanthomonas campestris). Xanthan gum is usually prepared from corn starch, and is an acidic extracellular heteropolysaccharide prepared from Xanthomonas campestris with black rot of cabbage, which takes carbohydrate as a main raw material, and is prepared by cutting 1, 6-glycosidic bond, opening branched chain, and bonding 1, 4-into straight chain by aerobic fermentation bioengineering technology. Xanthomonas campestris, black rot, was isolated in 1952 from the northern research institute of Piriliell, Illinois, and the cabbage extract was converted to water-soluble acidic extracellular heteropolysaccharide. The secondary structure of xanthan gum is that the side chain winds around the main chain skeleton reversely, and a rodlike double-spiral structure is formed through a hydrogen bond system. The tertiary structure of xanthan gum is a helical complex formed by weak non-covalent bonding between double helical rod structures. In the processing of the pesticide suspending agent, the addition of the xanthan gum has two modes, one mode is that the solid xanthan gum is added before sanding, and is evenly stirred and then sanded together with the suspending agent, and the processing method has the advantages of simple process and easy chain structure disconnection and unstable quality; and the other is adding aqueous solution in proportion after sanding, which has the advantages of easily obtaining the pesticide suspending agent with stable quality and has the defects of long water dissolution time in the using process, easy generation of agglomeration, complex operation and difficult adaptation to the production and application of the suspending agent due to the fact that the xanthan gum is a solid powdery substance. Therefore, in order to solve the problems, a method for quickly preparing a yellow-element glue solvent is urgently needed to be developed, and the method is applied to the production of a pesticide suspending agent so as to solve the problem of the production of the suspending agent and improve the production efficiency of the suspending agent. At present, no method for quickly dissolving a yellow glue solvent is applied to the aspect of pesticide suspending agents.
