POLYSTYRENE PHENOL POLYOXY ALKYL POLYMER AND PREPARATION METHOD AND APPLICATION THEREOF

摘要

Disclosed in the present invention is a polystyrene phenol polyoxy alkyl polymer and a preparation method and application thereof, relating to the technical field of pulping and papermaking. The polystyrene phenol polyoxy alkyl polymer is a polystyrene phenol polyoxyethylene/propylene/butylene ether or sulphate, phosphate and carboxylic ester polymers having a molecular weight of 240-7000; adding the polymer to aqueous cellulose papermaking slurry such that same has a surface reaction with organic pollutants or ink matter which changes the physical and chemical properties of the organic pollutants or ink, such that this matter is more easily separated and removed during the pulping process; the amount of organic pollutants and ink in the system is reduced, whilst the viscosity of organic pollutants is simultaneously changed and even eliminated; organic pollutant deposits during the pulping and papermaking process are thereby eliminated, achieving the objectives of improving paper quality and increasing papermaking productivity.
