Definitions

  • the invention relates to the invert glue for bulk sizing and surface sizing of paper described in the claims.
  • Reinforced rosins can be made by reacting maleic anhydride or other dienophilic compounds with rosin to increase the number of carboxylic acid groups.
  • a typical reinforced glue can contain about 1 to 30% maleinopinaric anhydride.
  • a glue with a high proportion of free rosin leads to better sizing and requires less alum.
  • a protective colloid By using a protective colloid, it is possible to produce a highly stable glue that contains up to 90% free rosin.
  • the Bewoid process produces a glue with a high proportion of free rosin, which contains about 90% free rosin, dispersed in a small amount of rosin soap and stabilized by the presence of about 2% casein or another protein.
  • the casein is used as a protective colloid to prevent the growth of rosin particles, keeping them in a fine state of breakdown.
  • the rosin is broken up mechanically in the presence of about 1 to 2% sodium hydroxide and about 2% casein.
  • the rosin is heated and subjected to mechanical shear stresses until it is divided into small particles.
  • a small amount of caustic soda (1.6 parts per 100 parts of rosin) is then added to the molten rosin to partially saponify it, and then casein (2.0 parts dispersed in 0.2 part of NaOH) is used to stabilize the dispersed rosin particles added.
  • the dissolved casein is incorporated into the molten rosin with vigorous stirring, whereupon an additional small amount of NaOH (0.2 part) is added, or the hot rosin melt is sprayed into water containing casein. Finally water is added to give a finished dispersion with about 45% solids which is used in this form.
  • This process is also referred to as "inversion process for the production of rosin glue" and the rosin glue thus produced is referred to as "invert glue”.
  • glue with free rosin was made according to U.S. Patent 2,393,179, using a non-alkaline dispersant, e.g. a sulfonated higher fatty alcohol was used.
  • a non-alkaline dispersant e.g. a sulfonated higher fatty alcohol was used.
  • the rosin was melted and the desired amount of dispersant was added with sufficient stirring to form a homogeneous melted mass.
  • a practically neutral or weakly acidic aqueous solution or dispersion of a protective colloid, e.g. Casein added forming a paste-like dispersion with a high solids content, which was then diluted with water to a solids content of 40 to 60% by weight.
  • a surfactant protein e.g. Soybean protein that prevents rosin particles from growing into larger aggregates.
  • glues with free rosin are dispersions of unsaponified resin acids with a certain percentage of resin soaps.
  • the dispersions were produced by the inversion process. They were mostly used with a free rosin content of 60 to 95% and also contained auxiliary emulsifiers and stabilizers such as stearates, triethanolamine, casein and waxes.
  • the reinforced rosins have so far not been suitable for the production of dispersions, since they usually had too high melting points, tended to crystallize or formed fine crusts when dispersed, which led to signs of sedimentation. It describes a paper glue and a process for its production in the form of an aqueous dispersion with a high content of free rosin, in which reinforced rosin is mixed at elevated temperatures with fatty acids, fatty acid mixtures and / or naphthenic acids and the dispersion was carried out in a known manner. The method was used as an inversion method.
  • DE-OS 24 26 038 discloses a process for the preparation of a practically stable aqueous dispersion of a rosin-based material suitable for use in the gluing of cellulose-like fibers for paper production, an unstable, aqueous dispersion containing at least 5% solids from 0 to 95% rosin and 100 to 5% of a reaction product of rosin with an acidic 'the rest'.
  • Swedish patent application 74 10 018-1 describes a practically stable, aqueous dispersion consisting essentially of water, rosin material and an alkali metal alkylbenzenesulfonate as a stabilizer for the rosin material.
  • the dispersions were made by passing a prepared mixture of the components through a homogenizer.
  • U.S. Patent 3,906,142 discloses an agent for sizing paper without the use of aluminum sulfate, which comprises a stable aqueous dispersion of a rosin reinforced by reaction with an alpha, beta-unsaturated carboxylic acid or corresponding anhydride, a protective colloid, e.g. Casein, and a volatile base, e.g. Ammonia, with at least 90% of the reinforced rosin unsaponified.
  • the inversion process was used to produce this agent, in which first the reinforced rosin was melted in a container equipped with a stirring and heating device. A dispersant and stabilizer was then prepared in another container by using a measured amount of a protective colloid, e.g.
  • an invert glue for the mass sizing of paper which contained an aqueous dispersion of a reinforced rosin, whose dispersant in solution anions of the formulas and where R represents an n- or branched alkyl radical having 4 to 18 carbon atoms, R 'represents an alkyl, alkenyl or cycloalkyl radical with fused rings having 10 to 20 carbon atoms and n was such a number that about 27 to 75% of the Molecular weight accounted for the CH 2 CH 2 0 group.
  • the use of protective colloids such as casein should not be necessary, but had to be worked with hot inversion water.
  • an invert glue for the mass sizing and surface sizing of paper is known, which contained in the aqueous resin dispersion as a dispersant compounds which have anions of the formulas in solution or dispersion and or in which R is an n-branched or branched alkyl group having 8 to 9 carbon atoms and R 1 is an n-branched or branched alkyl or alkenyl group having 12 to 20 carbon atoms and n is such a number, that about 21 to 76% of the molecular weight is accounted for by the OCH 2 CH 2 group.
  • the sizing agents described above were used in a pH range of 4.5 to 6 and required relatively large amounts of aluminum sulfate to be fixed on the fiber, which contaminates the waste water. If you previously wanted to glue in the neutral pH range of 6 to 8 paper, you had to use synthetic sizing agents, e.g. Use diketene derivatives instead of rosins. However, no adjustable sizing was possible with these synthetic sizing agents.
  • the invention has for its object an invert glue for bulk sizing and surface sizing of paper, containing an aqueous dispersion of a reinforced, unreinforced, hydrogenated or disproportionated and optionally esterified colophony resin or a mixture of such resins and a dispersant,
  • the digested casein or an emulsifier of the general formula contains, in which R represents an alkylphenyl, alkyl or alkenyl group or a cycloalkyl group with fused rings,
  • A represents a group of the formula -CH 2 COO or -SO s ,
  • M X + represents a cation, x represents 1 or 2 and n represents one Number is that about 21 to 76% of the molecular weight of the anion is accounted for by the group -OCH 2 CH 2 , which can be used for paper sizing in a wide pH range from 4 to 8 and does not have the disadvantages of synthetic sizing agents, ie has no adjustable
  • dispersant additionally contains cationic starch.
  • the glue according to the invention has a satisfactory effect in the pH range from 6.0 to 7.5, results in improved hydrophobization of the paper and, compared to other glues, requires considerably less aluminum sulfate for fixing to the fiber, which in turn means that the paper mills are polluted with waste water reduced.
  • the wastewater pollution from the product itself is reduced, since it has a significantly lower biochemical and chemical oxygen requirement compared to conventional glues.
  • the invert glue according to the invention preferably contains, in the aqueous dispersion, 5 to 50% by weight of the rosin or rosin mixture, 1 to 15% by weight, in particular 6 to 12% by weight, based on the resin or resin mixture, of dispersant and the remainder 100% by weight of water, the weight ratio of casein or emulsifier of the formula I to cationic starch in the dispersant being 20:80 to 80:20.
  • the invert glue according to the invention contains a cationic starch in the dispersant.
  • the cationic starch replaces part of the previously used casein or emulsifier of the formula I, improves the hydrophobicity of the paper in the neutral range, in particular at a pH of 6 to 7.5, supports the protective colloid effect and improves the retention of the glue and the mineral fillers on the fiber. Since the cationic starch alone does not act as a protective colloid, it was surprising that it supports the protective colloid effect of the casein.
  • a particularly preferred weight ratio of casein or emulsifier of formula 1 to cationic starch in the dispersant is 35:65 to 65:35. Excellent results are e.g. obtained with a weight ratio of 50:50.
  • Cationic starches which can be used according to the invention are known as such and are commercially available. You can by cationizing starch, e.g. Potato starch or corn starch with a known cationizing agent, e.g. Glycidyltrimethylammonium chloride, 3-chloro-2-hydroxypropyl-trimethylammonium chloride or the corresponding triethyl compounds. In this cationization, positively charged amino groups are bound to the starch molecule via ether bridges.
  • a known cationizing agent e.g. Glycidyltrimethylammonium chloride, 3-chloro-2-hydroxypropyl-trimethylammonium chloride or the corresponding triethyl compounds.
  • Cationic starch has already been used separately from paper glue as a flocculant and retention aid in paper production. With this known use of the cationic starch, a slight improvement in the hydrophobization of the paper is achieved. However, if the cationic starch is used in the dispersant of the invert glue according to the invention, its hydrophobic effect on the paper is surprisingly about 100 times stronger.
  • the rosin used in the invert glue of the invention can be any of the commercially available types of rosin, e.g. Root resin, balsam resin, tall resin and mixtures of two or more of these resins in the raw or refined state. Resins with a tendency to crystallize can be treated at elevated temperatures with formaldehyde or paraformaldehyde in the presence of an acid catalyst, e.g. p-toluenesulfonic acid, are treated in a manner known to those skilled in the art. So resin treated with formaldehyde can be used and falls under the term "rosin resin" used here.
  • an acid catalyst e.g. p-toluenesulfonic acid
  • an adduct reaction product of rosin with an acidic compound that does the rest contains, which is obtained by reacting rosin with the acidic compound at elevated temperatures, usually about 150 to 210 ° C.
  • the amount of the acidic compound used is adjusted so that a reinforced rosin containing from about 1 to about 30% by weight, preferably about 5 to about 12% by weight, of the added acidic compound based on the weight of the reinforced Rosin, is obtained.
  • Methods for making reinforced rosins are described in U.S. Patents 2,628,918 and 2,684,300.
  • Examples of acidic, the rest Compounds containing that can be used to make the reinforced rosin are the alpha, beta-unsaturated organic acids and their accessible anhydrides; specific examples include fumaric acid, maleic acid, acrylic acid, acrylamide, maleic anhydride, itaconic acid, ttaconic anhydride, citraconic acid and citraconic anhydride.
  • the preferred adduct-forming acid is fumaric acid.
  • acid mixtures can be used to produce the reinforced rosin.
  • Mixtures of various reinforced rosins can also be used. For example, a mixture of the acrylic acid adduct on rosin and the fumaric acid adduct on rosin can be used to produce the invert glues according to the invention.
  • esters of the resins mentioned with amino alcohols for example triethanolamine, triisopropanolamine, tributanolamine, or with glycerol, glycol or polyglycols are also suitable for producing the invert glue according to the invention. If a polyglycol is used as the esterifying agent, preference is given to using polyethylene glycols with molecular weights from 190 to 1,050.
  • the rosin may optionally be mixed with known additives, e.g. Waxes, in particular paraffin wax and microcrystalline wax, hydrocarbon resins, including those derived from petroleum hydrocarbons and terpenes, spindle oils or polyglycols, are mixed. This takes place in the melt or in solution, with up to about 100% by weight. preferably 30 to 50% by weight of the additive, based on the weight of the rosin, can be admixed. Part of the rosin can also be replaced with an extender. As extenders, which can be used in amounts of about 30 to 50% by weight, based on the weight of the rosin, are, for example Tall oil derivatives in question.
  • Waxes in particular paraffin wax and microcrystalline wax
  • hydrocarbon resins including those derived from petroleum hydrocarbons and terpenes, spindle oils or polyglycols
  • Mixtures of reinforced and unreinforced, hydrogenated or disproportionated rosin contain about 0 to about 100% reinforced resin and about 100 to about 0% unreinforced, hydrogenated or disproportionated resin.
  • Mixtures of reinforced resin, resin and resin extender contain about 25 to 49% reinforced resin, about 5 to 50% unreinforced resin and about 0 to 25% extender for the reinforced resin.
  • this mixture can contain any of the rosins listed above, reinforced or unreinforced, optionally also partially or practically completely esterified, hydrogenated or disproportionated or polymerized.
  • an aqueous solution or dispersion of the dispersant is first prepared.
  • the casein or emulsifier of the formula 1, the cationic starch and an acidic or basic disintegrant, for example formic acid, an aminoalkchol such as triethanolamine (TEA), potassium hydroxide solution, sodium hydroxide solution, ammonia or borax are mixed with water and heated.
  • Water is preferably introduced and the disintegrant is first stirred in, and then the casein or the emulsifier of the formula I and the cationic starch are added, whereupon the mixture is heated to 80 ° C., for example.
  • the cation M x + can be, for example, an alkali metal ion such as Na + or K + , a hydrogen ion, an ammonium ion or a triethanolammonium ion.
  • the effect of the cationic starch can, if appropriate, be increased by additionally adding a cationic resin to the dispersant, which can also be referred to as a protective colloid.
  • a cationic resin is a urea-formaldehyde resin which has been cationized using 3-chloro-2-hydroxypropyl-trimethylammonium chloride, 3-chloro-2-hydroxypropyl-triethylammonium chloride or another known cationizing agent.
  • the aqueous solution or dispersion of the dispersant or protective colloid obtained in the above manner is then added to the rosin or rosin mixture which has been melted beforehand and saponified by adding small amounts of a saponifying agent such as sodium hydroxide solution, potassium hydroxide solution or triethanolamine.
  • a saponifying agent such as sodium hydroxide solution, potassium hydroxide solution or triethanolamine.
  • the resin or resin mixture is melted at about 160 ° C and after saponification is cooled to about 120 ° C before adding the dispersant.
  • the saponified resin has been mixed with the protective colloid, the mixture is diluted with water to the desired content, with inversion occurring.
  • Example 1C By heating a mixture of 91 parts of the resin of Example 1A or of Example 14A and 9 parts of glycerin with stirring to 200 ° C and cooling to room temperature after the reaction was complete, a reinforced resin esterified with glycerin was prepared.
  • an inverted glue was prepared from 200 parts of the above esterified resins, 6 parts of 25% NaOH or KOH or 4 parts of triethanolamine and 60 parts of the protective colloid solution according to one of Examples 1B, 14B or 15B.
