Bactericidal and preservative agent combination for repair-regeneration of microbial pollution products

Abstract

The invention relates to a bactericidal and preservative agent combination for the repair-regeneration of microbial pollution products, which comprises the following active ingredients: a preservative agent A, a preservative agent B, a bactericide, solvents, additives and water, wherein the preservative agent A is formed by bronopol, the preservative agent B is formed by parachlorometaxylenol PCMX and a phenoxyethanol mixture, and the bactericide is formed by 2,2-dibromo-3-nitrilo-propionamide DBNPA or polyhexamethylene biguanidine hydrochloride PHMB. Through one-time addition, the bactericidal and preservative agent combination disclosed by the invention has strong synergistic, preservative and bactericidal effects, and can concurrently have the functions of bactericidal repair and corrosion and mildew prevention in the period of re-storage, thus most of industrial water-based products metamorphosed by microbial pollution are reused. The bactericidal and preservative agent combination disclosed by the invention has the advantages of reasonable formula, advanced process, high cost performance, low toxicity, good operational feasibility, bactericidal and preservative effect, and the like, and is verified through a lot of industrial practices.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical bactericidal preservatives, and relates to a bactericidal preservative composition for repairing and regenerating microbially polluted products, in particular to a high-efficiency antiseptic composition used for repairing and reusing industrial water-based products deteriorated by microbial contamination. Bactericidal preservative composition. Background technique [0002] Water-based industrial products such as various detergents, daily chemical additives, papermaking additives, water treatment agents, coatings, adhesives, metalworking fluids and other products contain water and various additives and other organic substances, which are harmful to the growth and reproduction of microorganisms. It provides abundant carbon sources, nitrogen sources, inorganic salts and growth factors, which are easily polluted and deteriorated, and the economic losses caused by microbial contaminatio...

Problems solved by technology

[0006] But the DBNPA solution of single component all has very big defect in making and application, mainly shows in: (1), it is very difficult to dissolve 20% or the DBNPA of higher concentration in the solvent, needs stirring for a long time, also needs heating in winter , consume energy and make the DBNPA active ingredient decompose and lose again, and the viscosity is large, and the operation is inconvenient; (2), after DBNPA is added to the deteriorated product, the stability is poor, easy to delaminate, change color, and the physical properties cannot recover to the state of conventional products; ( 3) The DBNPA solution only plays a bactericidal role. It is easily decomposed under normal conditions, especially when used in spoiled products with a pH value greater than 7. The half-life is very small, and it will be completely decomposed in about a week. Anti-corrosion and anti-bacterial; (4), DBNPA solution has a short storage period, and it only takes half a year to seal and avoid light at room temperature
