Definitions

  • the present invention relates to a method for the production of a coating color, containing a highly concentrated starch solution for the coating of paper and board, to the use of said highly concentrated starch solution as a binder in a coating color, and to a coating color obtainable by said method.
  • Coating colors are used for coating of both paper and board products, e.g. for coatings that conventionally contain pigments, binders, and other additives, such as thickeners, foam retardants, dispersing agents, viscosity regulating agents, and dyestuffs.
  • pigments are kaolin and calcium carbonate.
  • the main function of the binders is to bind the pigments to the paper and board surface and to keep the pigment particles as such together. Normally, the binders are divided in two groups, i.e. water soluble binders and latex binders. The main function of the water soluble binders is to act as pigment binder and to provide water retention.
  • the latex is comprised of polymers dispersed in water and is normally used in combination with a water soluble biopolymeric binder, such as starch, starch derivatives, or CMC (carboxy methyl cellulose).
  • a water soluble biopolymeric binder such as starch, starch derivatives, or CMC (carboxy methyl cellulose).
  • a dextrin has the advantage of being cold water soluble directly in the pigment solution and therefore not bringing any extra water into the coating color.
  • dextrin there is a drawback with dextrin, i.e. the small contribution this biopolymer gives to the water retention of the coat- ing color.
  • U.S. Patent Application No. 2010/00159104 discloses a procedure to gelatinize and dissolve starch for use in an adhesive composition, ending with a higher concentration than otherwise possible with conventional technique, i.e. a starch concentration of more than 35%. With this technique a starch solution essentially free from granules is obtained. Due to the higher starch concentration in the slurry preparation obtained the achieved gelatinized product creates a higher viscosity which in turn generates a need of higher steam pressure than in a conventional cooking procedure with a view to obtaining a solution.
  • U.S. Patent Application No. 2010/0058953 discloses the use of legume based dextrin for coating applications, e.g. for laying paper or flat carton.

  • a cooked starch solution intended as a component in a coating color for coating applications, such as for top coatings, having a high- er starch content compared to known starch solutions for the same purpose is obtained with the method according to the present invention.
  • the present invention also refers to use of the highly concentrated starch solution having a starch dry matter content of 40-70% produced in the evaporation step in the method according to the present invention as a binder in a coating color for the coating of paper and board.
  • the present invention refers to a coating color obtainable by the method according to the present invention.
  • Figure 1 discloses a plant for the production of a highly concentrated starch solution by use of the method according to the present invention.

  • roots and tubers such as potato and tapioca
  • grains and cereals such as wheat, barley, corn, and rice
  • legumes such as peas and beans
  • the raw material also includes other varieties of these starches, e.g. high amylose or high amylopectin starch, as well combinations or blends thereof.
  • the starch involved in the present invention may also be a modified starch.
  • modified starches are starch esters, such as acetates, phosphates, sulfates, sulphosuccinated, succinated, etc; and starch ethers, such as cationic and anionic starch ethers, hydroxy- propylated starches etc; crosslinked starches, such as sodium trimetaphos- phate reacted starches, epichlorohydrine reacted starches, etc.

  • the modified starch is warm water soluble it includes a dry powder and/or an intermediate starch, such as a cake or a slurry.
  • a warm water soluble starch is gelatinized and dissolved with a process known in the art, batch or continuous cookers, e.g. a jet cooker, are used, wherein the cooked starch normally has a solid concentration of more than 20%, preferably 30- 45%.
  • a second preparation step an evaporation is performed, and the solution is thereby concentrated to levels of starch concentrations of higher than 40% in dry matter content, preferably 40-70%, and most preferably between 45 and 65%.

  • the starch solution having been subjected to the evaporation is then fed from the evaporation device 4 to the collection vessel 5, from which the starch solution is recirculated back to the evaporation device 4 by use of the circulation pump 6 as long as the desired starch concentration in the starch solution exiting the evaporation device 4 not yet has been reached.
  • the starch density, corresponding to a specific starch concentration, in the collection vessel 5 is continuously measured with a control unit (not shown in Figure 1 ).

  • the coating obtained on said paper or board surface has the following advantages compared to corresponding known coatings: It has a higher dry matter content compared to a coating color containing a conventionally cooked starch, wherein less water has to be removed for obtaining the required total dry content interval of approximately 65-72% for a conventional coating color.
  • the coating color produced with the method according to the present invention gives a coating having a better water retention and a higher surface strength compared to a coating color containing dextrin as the biopolymer binder.
  • the higher dry content in the starch solution gives the possibility to lower the latex content, thereby reducing the costs and being a more environmental-friendly alternative, without decreasing the dry content of the latex based coating color.
  • the starches were then dispersed in room temperate water with a mixer (Eurostar digital, type Model Euro ST-D from IKA-Werke GmbH) to a starch slurry with a starch dry matter content corresponding to 30-45% for the different starches.

Further, as stated above, the method according to the present invention also allows a reduction of the amount of latex in the coating color and thereby also a cost reduction. The cost reductions disclosed above more than well compensate for the initial energy cost for the increase of the starch dry matter content from what is possible to obtain with conventional techniques up to starch dry matter contents of more than 40%.
