Definitions

  • the present disclosure relates to a method for improving sizing efficiency of an ASA sizing agent in a paper-making process.
  • the invention relates to a method for improving the sizing efficiency of a polymer emulsifier emulsified ASA emulsion by treating paper-making filler particles with a hydroxyl-containing hydrocarbon natural polymer polysaccharide compound in the sizing process of paper- making.
  • Paper is a cellulose-containing fiber composite having a typical polar, strongly hydrophilic character, which is to say it can be easily wetted and swelled by aqueous system.
  • aqueous system When writing on and imprinting paper, and also when processing paper, this results in excessive and uncontrolled penetration of water and other liquids (such as ink, printing inks) into the fibrous web.
  • the resulting problems include weakening of the internal fiber bonding strength, worsening of the mechanical properties, decrease in the dimensional stability, and very poor writing and imprinting ability.
  • sizing agents In order to control the wetting and penetration behavior so called sizing agents are employed, which through partial hydrophobization counteract the aforementioned behavior.
  • auxiliary agents can be added both to the aqueous cellulose pulp (internal sizing) or be applied by way of a surface treatment of the previously formed paper web using an appropriate application system such as a size press, film press, coater and the like (surface sizing). Both methods are employed together for some types of paper.
  • neutral sizing agents such as typical neutral sizing agents including, e.g., alkyl ketene dimer (AKD) and alkenyl succinic anhydride (ASA) are used.
  • typical neutral sizing agents including, e.g., alkyl ketene dimer (AKD) and alkenyl succinic anhydride (ASA)
  • ASA alkenyl succinic anhydride
  • the neutral sizing agent itself is a water insoluble oil. Therefore, it must be in an emulsion state before addition to the furnish for internal sizing.
  • an appropriate emulsifier is of paramount importance.
  • Cationic starch and synthetic acrylamide based polymers arc normally used as emulsifiers.
  • polymer emulsifiers are attracting more attention due to the fact that a large amount of cationic starch has to be used to achieve target sizing efficiency, whereas a relatively much smaller amount of synthetic polymer can be used to obtain a similar effect.
  • the use of a large amount of cationic starch greatly increases the chemical oxygen demand (COD) level in the water released from a paper mill, which might cause serious environmental pollution. From environmental protection point of view, it is desirable to replace cationic starch with cationic polymers.
  • fillers such as CaC0 3 , Ti0 2 are being added to paper to decrease fiber consumption.
  • typically used fillers detrimentally affect the sizing of alkaline paper. With increasing ash content, that is, more fillers added, the neutral sizing is negatively impacted. More specifically, the effect of the neutral sizing when using polymeric emulsifiers is not ideal compared to cationic starch emulsifiers.
  • U.S. Patent No. 5,411,639 discloses that a starch / fatty acid soap complex can be obtained by cooking the starch and then mixing the aqueous solution of the starch and the fatty acid soap (sodium or potassium salt of fatty acid) in certain conditions. When such complex is used to modify the filler, the sizing efficiency of the AKD can be effectively improved.
  • U.S. Patent No. 5,527,430 also discloses a method for improving ASA sizing efficiency wherein a polymer is used to surface modify the fillers so that the surface of the filler become hydrophobic.
  • a fatty acid or a salt of the fatty acid is used, and the starch / fatty acid complex is used in a large amount, which causes a complex process.
  • the use of large amounts of chemicals for surface modifying calcium carbonate is not economically suitable for practical applications.
  • the present invention solves the problems by providing a method for improving sizing efficiency of a polymer emulsifier emulsified ASA emulsion, which can significantly improve the efficiency of the neutral sizing.

  • the invention provides a process for paper-making comprising the steps of: adding paper-making filler particles modified by a hydroxyl-containing hydrocarbon natural polymer polysaccharide into a pulp slurry, at the same time of or before or after adding a polymer emulsifier emulsified ASA emulsion into the pulp slurry
  • the sizing efficiency of the ASA sizing can be significantly improved when a polymer emulsifier is used as an emulsifier.
  • the sizing efficiency of the synthetic polymer-emulsified ASA emulsion is not less than the sizing efficiency of the ASA emulsion that is emulsified by a cooked cationic starch emulsifier.
