Problems solved by technology

The introduction of a higher concentration of emulsifiers is not conducive to the protection of the environment. In addition, high concentrations of emulsifiers lead to increased liquid viscosity, which in turn affects the physical and chemical effects of sprays.

Abstract

The invention relates to the field of chemical industry, in particular to a non-ionic surfactant composition and application thereof. The non-ionic surfactant composition is prepared from high molecular polyoxyethylene-polyoxypropylene ether [HO(C2H4O)a-(C3H6O)b-(C2H4O)cH and fatty alcohol-polyoxyethylene ether [CnH2n-1(CH2CH2O)3H according to the weight ratio of 1.5-2.5:1, wherein b is an integer ranging from 30 to 40, and the sum of a and c is an integer ranging from 5 to 10], and n is an integer ranging from 12 to 16]. When the non-ionic surfactant composition is applied as an emulsifier of a water-in-oil emulsion, the capability of water emulsion reaches 95 percent. The invention also discloses a water-in-oil emulsion comprising the following components in parts by weight: 0.5-2 partsof non-ionic surfactant compositions, 5-20 parts of oil and 78-94.5 parts of water, and has uniform dispersion and stable property.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a nonionic surfactant composition and its application. Background technique [0002] Surfactants refer to substances that have strong surface activity and can reduce the surface tension of liquids. High molecular polyoxyethylene-polyoxypropylene ether is a kind of non-ionic surfactant. By designing different copolymerization ratios, we can achieve different hydrophilic and lipophilic balances. Among them, the increase of polyoxypropylene can enhance lipophilicity; The increase of oxyethylene can enhance the hydrophilicity. However, the solubilization ability of such substances is weak. Fatty alcohol polyoxyethylene ether is also a kind of nonionic surfactant commonly used in industry. In two-phase liquids that are immiscible with each other, the above substances can be used as emulsifiers. By reducing the surface tension between the two phases of oil and water to a large exten...
