Embodiment Construction

[0007] For further illustrating the present invention, specifically illustrate in conjunction with following examples:

[0008] A water-emulsion type L40 surfactant, the preparation method is: mixing active substance A and solvent A with a weight ratio of 10:10 to obtain mixture A; then mixing active substance B and solvent B with a weight ratio of 10:10:1 and auxiliary agent C to obtain mixture B, and then mix mixture A, mixture B and auxiliary agent D according to the ratio of 6:5:2 by weight, and after homogeneous mixing, the product is obtained; wherein the active substance A is sucrose ester; solvent A is 5:1 methanol aqueous solution; active substance B is NP-50 (non-ionic emulsifier NP series); solvent B is 4:1 ethylene glycol aqueous solution; auxiliary agent C is CMC-Na; auxiliary agent D is anionic PAM (alias: flocculant No. 3; anionic polyacrylamide; polyacrylamide dry powder (anionic); polyacrylamide colloid type I; polyacrylamide colloid type II; hydrolyzed polyac...

Abstract

The invention relates to a water emulsion type L40 surface active agent. A preparation method of the water emulsion type L40 surface active agent comprises the following steps: mixing an active matter A with a solvent A based on the weight ratio of 10: 10 so as to obtain a mixture A; mixing an active matter B with a solvent B and an assistant C based on the weight ratio of 10: 10: 1 so as to obtain a mixture B; mixing the mixture A with the mixture B and an assistant D based on the weight ratio of 6: 5: 2; and homogenizing and uniformly mixing so as to obtain the water emulsion type L40 surface active agent. The water emulsion type L40 surface active is high in quality and relatively low in comprehensive cost, can be widely popularized, and is low in dosage, so that down-stream products are excellent in performances and remarkable in economic benefit. By adopting the water emulsion type L40 surface active agent, the problems that the cost of preparing pesticide is high, serious pollution is brought to the environment, and the benefit is low, can be solved, and furthermore, the residual toxicity of the crops can be effectively degraded, the application of pesticide for the crops is improved, the rain resistance and the drought resistance of the crop can also be improved; and the water emulsion type L40 surface active agent plays an important role in updating the promotion of surface active agent products, realization of increase crop production and income of farmer, and reduction of the pollution of pesticides products to the environment.

Description

technical field [0001] The invention relates to a novel water emulsion type L40 surfactant. Background technique [0002] Water-emulsion L40 surfactant is one of the main types of pesticide surfactants, the main component of pesticide mixed emulsifiers, and the most widely used category of pesticide adjuvants. It can be used alone as a pesticide adjuvant, and the mixed adjuvant prepared by mixing with anionic surfactant has better performance, but due to technical difficulties, our country has been unable to break through in this field. [0003] There are many preparation methods for water emulsion L type 40 surfactant, and the main method is to dissolve and mix active substances A, B, solvents A, B, additives C, D in one step to obtain the product. This method is easy to operate and control, the equipment is relatively simple, and the investment is small, but the product performance is unstable, resulting in the reduction of subsequent product quality.
