Problems solved by technology

However, some fungicides have unsatisfactory compatibility with latex, which affects the physical and chemical properties of latex subsequent processing; some fungicides are not only costly, but also harmful to the human body and seriously pollute the environment. Difficult to handle; if additional surfactant is added, although it can exert its emulsification effect to stabilize the latex, thereby reducing the amount of fungicides, it cannot guarantee good coexistence with fungicides; since latex is an anionic colloid, the surface of quaternary ammonium salts active agent not applicable

Abstract

The invention discloses an anionic surfactant having bactericidal activity and a preparation method thereof. The anionic surfactant has a structure shown in the following general formula. Cyanuric chloride, alicyclic amine, sulfamic acid and aminobenzimidazole as raw materials are mixed according to a reasonable feeding ratio and undergo a three-step synthesis reaction to produce the anionic surfactant. The anionic surfactant has surfactant properties and has bactericidal activity. The anionic surfactant having bactericidal activity solves the problem of poor compatibility of a surfactant and a bactericide, overcomes charge limit, widens an application range of the anionic surfactant having the bactericidal activity, can be treated easily in a use later period, has a less use amount and has important theoretical and practical significances. In the general formula, R1 represents -(CH2)5CH3, -(CH2)7CH3, -(CH2)9CH3 or -(CH2)11CH3 and R2 represents -CH2-, -(CH2)2-, -(CH2)3- or -C6H4.

Description

Technical field: [0001] The invention relates to a surfactant, in particular to an anionic surfactant with bactericidal activity. Background technique [0002] Surfactant is a functional fine chemical. Due to its amphiphilic molecular structure, it can be directional adsorbed on the two-phase interface in the dissolved state, thereby significantly reducing the surface tension of the solution and the interfacial tension between the interfaces. Surfactants are used in a wide range of fields, ranging from petroleum exploration, industrial cleaning, papermaking, wastewater treatment, to the use of pesticides and fertilizers in agriculture, to washing, sterilization, and solubilization in the medical field, to daily cleaning products, cosmetics etc., and has expanded to high-tech fields such as new environmental protection materials. [0003] As early as the middle of the 20th century, some surfactants were detected to have bactericidal function, so they have been widely used as...
