Problems solved by technology

Conventional defoamers are mostly silicone defoamers, but their defoaming performance is greatly reduced in some corrosive working environments, and the existing defoamers are easily corroded by other components or contaminated by bacteria during the defoaming process. Contributes to the overall quality and performance of the paper

Abstract

The invention discloses an anticorrosion antibacterial defoaming agent, made from, by weight, 5060 parts of polyurethane elastomer, 37 parts of nano silver oxide, 26 parts of nano zinc oxide, 913 parts of 2-methylpropanol, 711 parts of p-toluenesulfonic acid, 25 parts of magnesium 3-picolinate, 14 parts of silver citrate, 610 parts of cellulose ecteola, 1013 parts of terpene resin, 914 parts of 2-methylacrolein, 58 parts of N-methylaminopropyltrimethoxysilane, 26 parts of 4-methylthiazole-5-carboxaldehyde, 713 parts of cyclic AMP, 1216 parts of phentolamine, and 48 parts of azodicarbonamide. The anticorrosion antibacterial defoaming agent, as a papermaking aid, has the good integrated properties of corrosion resistance, bacterial resistance and high temperature resistance, is more widely applicable and meets the diverse needs of the market.

Description

technical field [0001] The invention belongs to the technical field of papermaking additives, in particular to an anti-corrosion and anti-bacterial defoamer and a preparation method thereof. Background technique [0002] In the papermaking process, from washing, screening, bleaching, thickening, pulp supply system, surface sizing, coating, black liquor recovery, etc., they are all affected by foam to varying degrees. These foams will interfere with normal production and make paper quality worse. Decrease, resulting in poor sizing degree, poor quantitative uniformity of the banner, spots, light transmission points and small holes on the paper surface, etc., and even paper breakage. These effects cannot be ignored. For example, since the pulping raw materials contain natural substances such as fatty acids and resin acids, they react with chemicals such as caustic soda and sulfide to form foaming substances such as fatty acid soaps and resin acid soaps, and the stability of ma...
