Problems solved by technology

[0003] Currently commonly used dodecyl dimethyl benzyl ammonium chloride, tetradecyl dimethyl benzyl ammonium chloride and dodecyl dimethyl benzyl ammonium bromide have better slime stripping effect, but The duration of sterilization is not long, and it is difficult to effectively control the growth and harm of microorganisms in circulating cooling water; while dithiocyanomethane is sensitive to the pH value of water, has high toxicity, and its application range is limited to a certain extent
At the same time, some of these types of fungicides have been used in circulating water treatment since they were introduced into China in the 1970s. Newer ones such as isothiazolinone and glutarald

Abstract

The invention discloses a compound antibacterial preservative, which comprises the following components in parts by weight: 40-70 parts of one or a mixture of dodecyl dimethyl benzyl ammonium chloride, tetradecyl dimethyl benzyl ammonium, hexadecyl dimethyl benzyl ammonium chloride and octadecyl dimethyl benzyl ammonium chloride, 20-50 parts of didecyldimethylammonium chloride, 1-10 parts of stabilizer, and 0-400 parts of deionized water. The invention further relates to a preparation method of the antibacterial preservative. The compound antibacterial preservative disclosed by the invention is capable of effectively controlling breeding of bacteria and algae in water and growth of slime, and has the effects of sterilizing and killing algae effectively for a long time, well peeling, dispersing and permeating slime and simultaneously removing oil, deodorizing and inhibiting corrosion; and the compound antibacterial preservative is non-toxic, environmentally friendly, high-efficiency and free from any environmental pollution, and is applied to controlling bacteria and algae of paper-making and circulating cooling water systems.

Description

technical field [0001] The invention relates to a composite bactericidal antiseptic and also relates to a preparation method of the bactericidal antiseptic. Background technique [0002] The control of bacteria and algae in papermaking or circulating cooling water systems is usually controlled by adding fungicides. Commonly used fungicides are divided into two categories, namely oxidizing fungicides and non-oxidizing fungicides, of which oxidizing fungicides include chlorine gas, sodium dichloroisocyanurate or excellent chlorine, trichloroisocyanuric acid or strong Chlorine, active bromine, etc.; non-oxidizing fungicides include dodecyl dimethyl benzyl ammonium chloride (referred to as '1227'), dodecyl dimethyl benzyl ammonium bromide (brogeramine), fourteen Alkyl dimethyl benzyl ammonium chloride (referred to as '1427'), tetradecyl dimethyl ammonium bromide, isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., the above types of fungicides are often It only has one ...
