Definitions

  • the present invention relates to an aqueous sizing emulsion and more specifically to emulsions containing a substituted succinic anhydride as sizing agent, commonly referred to as ASA, and colloidal cationic silica particles.
  • ASA succinic anhydride
  • colloidal cationic silica particles colloidal cationic silica particles
  • Aqueous emulsions of substituted succinic anhydrides are used for sizing of neutral to slightly alkaline stocks at which pH range calcium carbonate effectively can be used as filler material.
  • substituted succinic anhydrides are hydrophobic, the size has to be evenly distributed in an aqueous phase before being added to the cellulosic stock.
  • sizing emulsions are prepared in the vicinity of the end user, i.e. in the paper mill, in the presence of surfactants and/or polyelectrolytes such as starches.
  • Substituted succinic anhydrides generally provide satisfactory sizing of the paper. Though, sizing properties of substituted succinic anhydrides commonly deteriorates with cellulosic stocks having a high conductivity due to a high amount of charged particles and/or stocks having a significant amount of dissolved organic substances, i.e. lipophilic wood extractives, such as resin acids, fatty acids, fatty esters, etc.
  • WO-A1-9731152 refers to sizing emulsions comprising a reactive sizing agent and an anionic microparticulate material rendering the emulsion anionic. Furthermore, it is stated that the inclusion of cationic compounds is undesirable, thus, the sizing dispersions are essentially free from cationic compounds.
  • the invention provides an aqueous emulsion comprising a substituted succinic anhydride and positively charged colloidal silica particles or positively charged colloidal aluminia particles or positively charged colloidal zirconia particles. Additionally, the invention provides a process for the production of cellulose-based products in which a sizing emulsion is added to the stock or applied as a surface size.
  • the present size emulsion makes it possible to produce paper with improved sizing over conventional size emulsions at a corresponding dosage and to use a lower dosage of substituted succinic anhydride sizing agent to attain a corresponding level of sizing.
  • the possibility of using lower amounts of sizing agent to obtain in-specification sizing reduces the risk of accumulation of non-adsorbed sizing agents in the white water recirculating in the process, thereby reducing the risk of aggregation and deposition of the sizing agent on the paper machine.
  • Starch cannot be used in emulsions without being pretreated by cooking, a treatment which greately affect the properties of starch. Accordingly, it is important how the cooking is implemented in order to obtain a starch with adequate characteristics. Furthermore, there is always a possibility that the level of bacterial activity may increase in cooked starch impairing the properties. It is therefore desirable to be able to reduce the amount of starch or even omit starch in sizing emulsions of ASA.
  • the sizing agent according to one preferred embodiment of the invention is a substituted succinic anhydride, commonly referred to as ASA.
  • Suitable acid anhydrides can be characterized by the general formula (I) below, wherein R 3 and R 4 can be identical or different and represent saturated or unsaturated hydrocarbon groups suitably containing from 8 to 30 carbon atoms, or R 3 and R 4 together with the -C-O-C- moiety can form a 5 to 6 membered ring, optionally being further substituted with hydrocarbon groups containing up to 30 carbon atoms.
  • acid anhydrides which are used commercially include alkyl and alkenyl succinic anhydrides and particularly isooctadecenyl succinic anhydride.
  • iso-octadecyl succininc anhydride iso-octadecyl succininc anhydride, n-hexadecenyl succinic anhydride, dodecenyl succinic anhydride, decenyl succininc anhydride, octenyl succinic anhydride, triisobytenyl succinic anhydride, 1-octyl-2-decenyl-succinic anhydride and 1-hexyl-2-octenyl-succinic anhydride.
  • Suitable acid anhydrides include the compounds disclosed in US 3102064, US 3821069, US 3968005, US 4040900 and Re 29960 which are incorporated herein by reference.
  • the sizing dispersions according to yet another preferred embodiment of the invention comprise positively charged colloidal silica or positively charged colloidal alumina or positively charged colloidal zirconia.
  • Stable cationic aquasols of colloidal silica, alumina, or zirconia are well known in the art, for example from US 3007878, US 3620978, 3719607, 3754126 and US 3956171 which all are incorporated herein by reference.
  • these sols contain colloidal, dense, finely divided particles, suitably silica.
  • Typical known sols are those containing positively charged particles having a dense silica core coated with a hydroxyl of other oxygen compound of a polyvalent metal such as aluminium, along with an anionic counter ion such as a chloride, acetate or nitrate.
  • Preferred positively charged silica particles or sols are available from Eka Chemicals.
  • suitably inorganic positively charged colloidal silica particles are contained in the emulsions.
  • the positively charged colloidal silica particles are inorganic silica particles which suitably are aluminium-modified. It is preferred that the particles are surface-modified with aluminium.
  • the general method for preparing positively charged cationic silica sols starts suitably from aqueous sols of silica which are reacted with a basic salt of a polyvalent metal to give the sol particles a positive surface charge and stabilisers such as boric acid, alkali metal bases, alkaline earth metal bases, ammonia etc.
  • the polyvalent metal salt is usually an aluminium salt, however, it is also possible to use basic salts of other polyvalent metals for preparing cationic silica based sols, such as chromium, zirconium. Any basic salt which is water soluble and renders the desired positively charged surface can be used and typically the cationic silica is prepared using chlorides, nitrates or acetates of the metal. Preferably, poly aluminium chloride is used as basic salt.

  • the cationic silica particles can have positively charged species of the polyvalent metal, preferably aluminium, on their surface and the weight ratio of Al 2 O 3 to SiO 2 can be in the range from 1:20 to 4:1, suitably within the range of from 1:10 to 2:1 and preferably within the range of from 1:5 to 1:1.
  • the colloidal particles are suitably contained in aqueous sols.
  • the emulsions according to the invention can have contents of substituted succinic anhydride sizing agents from about 0.1% by weight up to about 50% by weight.
  • the content of substituted succinic anhydrides sizing agent is suitably within the range of from 1 up to 40% and preferably from 2 up to 30% by weight.
  • the weight ratio of substituted succinic anhydride sizing agent to positively charged colloidal particles, preferably positively charged colloidal silica particles can be within the range of from 1:1 to 100:1.
