Abstract

The invention discloses a papermaking bactericidal preservative, which belongs to the technical field of papermaking industry. According to the technical scheme, the papermaking bactericidal preservative is composed of the following raw materials in parts by weight: 23-45 parts of 2,2-dibromo-3-nitrilo propionamide, 5-12 parts of an ethylene glycol organic solvent, 1-10 parts of polyhydric alcohol, 1-10 parts of cyclic nitrogen sulfur compounds, 1-10 parts of organic nitrogen sulfur compounds, 5-25 parts of 2-sulfhydryl methylthio benzothiazole, 1-10 parts of methylene bisthiocyanate, 2-8 parts of an emulsifier and 5-25 parts of polyhexamethylene guanidine hydrochloride. Compared with the prior art, the papermaking bactericidal preservative disclosed by the invention has a quick sterilization function, low resistance to drugs and a wide application range, and is capable of reducing dissolved matters and colloidal substances accumulated in a white water system, maintaining the cleanness of water, reducing the used amount of other chemical substances in a papermaking process, reducing the papermaking cost and improving the quality of paper.

Description

technical field [0001] The invention relates to the technical field of papermaking industry, in particular to a bactericidal preservative for papermaking. Background technique [0002] With the development of the paper industry and the increasing shortage of available resources in the world, many manufacturers have begun to recycle waste paper and papermaking white water to reduce production costs and reduce environmental pollution, which inevitably brings a large number of bacteria into the paper machine system. Due to the presence of a large number of microorganisms in the system, it is easy to cause sludge to form in various equipment and piping systems through which pulp and white water flow. The slurry will bring great harm to the production process and product quality. Therefore, in addition to doing a good job of cleaning and eliminating or reducing hazards in production, bactericidal preservatives should be added to pulp and coatings to inhibit or kill microorganism...
