Abstract

The invention discloses a papermaking sterilizing preservative which comprises the following components in percentage by weight: 40-80% of 2, 2-dibromo-3-nitrilo-propanamide, 10-30% of ethylene glycol system organic solvent, 1-10% of polyhydric alcohols, 1-10% of cyclic nitrogen system sulfur system chemical compound, and 1-10% of organic nitrogen system sulfur system chemical compound. According to the papermaking sterilizing preservative provided by the invention, the bacterium can be quickly killed, the papermaking sterilizing preservative is low in drug resistance and wide in application range, the accumulation of dissolved matter and colloid in a white water system can be reduced, the cleanness of water quality can be kept, the use of the other chemical substances in the process of papermaking can be used, the papermaking cost can be reduced, and the quality of finished paper can be improved.

Description

technical field [0001] The invention relates to a papermaking chemical, in particular to a papermaking bactericidal antiseptic. 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 microorganisms to improve paper performa...
