Definitions
- This invention relates to paper sizing compositions, methods for making such compositions, processes for sizing paper products using these compositions and paper products which have been sized with these compositions.
- Paper is used, for convenience, to mean all forms of paper, paperboard and related products whose manufacture involves the employment of a sizing agent upon cellulosic or other fibres.
- Paper sizing agents are usually employed either by being added to the cellulosic or other fibre stock from which a web is later made or by being applied to the surface after the web has been formed. Rosin-based sizing agents depend for their sizing effect upon the formation of electrostatic bonds between the sizing agent and the cellulosic or other fibres of the paper stock or web.
- paper sizing agents are usually in the form of stable dispersions and they cause sizing by depositing rosin-based or other materials on to the fibre stock or the paper web, so that sizing essentially involves breaking the stable dispersion. This can occur on contact between the dispersion and the stock or web, where the latter is effective to destroy the stability of the dispersion.
- adequate sizing does not arise from mere contact of the paper sizing agent with the paper stock or web. Instead, it requires the presence of a co-reactant to break the dispersion and so cause the desired deposition of sizing components on the fibres of the paper stock or web.
- co-reactants are aluminium compounds and, especially, aluminium sulphate, papermaker's alum and the polyaluminium chlorides.
- dispersions comprising a rosin component and an amine salt of a rosin acid, which are stable and which impart excellent sizing properties to paper, can be prepared by the incorporation of at least one aluminium compound into a composition of a rosin size and an amine salt of a rosin acid.
- a paper sizing composition in the form of a preformed stable aqueous dispersion for subsequent use in a paper-sizing process, characterised in that the composition has the ability to size paper stock, sheet or web to an effective extent when brought into contact with the stock, sheet or web during the sizing process and comprises the material obtainable by addition of at least one aluminium compound to an aqueous dispersion comprising rosin size and an amine salt of a rosin acid.
- the invention also provides a method of manufacture of a paper-sizing composition, the composition being characterised in that it is in the form of a stable aqueous dispersion for subsequent use in a paper-sizing process and has the ability to size paper stock, sheet or web to an effective extent when brought into contact with the stock, sheet or web during the sizing process, the method comprising first forming an aqueous dispersion comprising rosin size and an amine salt of a rosin acid and then introducing at least one aluminium compound into the dispersion; and a process of manufacture of a sized paper product, wherein a paper-sizing composition is added to fibre stock which is then made into paper or is applied as a surface size to a prepared paper web or sheet, the composition being characterised in that it comprises the material obtainable by addition of at least one aluminium compound to an aqueous dispersion comprising rosing size and an amine salt of a rosin acid.
- Rosin is a solid resinous material which occurs naturally in the oleoresin of pine trees. It is obtained from one of three main sources, the oleoresin exudate of living pine trees, the oleoresin contained in the aged stumps of pine trees and from the tall oil produced as a by-product in the kraft paper industry. Rosin is a complex mixture of cyclic terpene carboxylic acids together with a small amount of non-acidic components. A major constituent of rosin is the tricyclic doubly unsaturated mono-carboxylic acid, abietic acid.
- rosin may therefore be reacted with dienophilic carboxylic acids such as maleic acid, maleic anhydride or fumaric acid to form a tetracyclic polycarboxylic acid. This reaction with these dienophiles is commonly termed fortification.
- the product of such reaction between rosin and a dienophile is commonly termed a fortified rosin. Fortified rosin dispersions are used as sizing compositions in the paper sizing industry and the novel dispersions of this invention may comprise either rosin or fortified rosin or a mixture of the two.
- the rosin may have been treated with formaldehyde in order to enhance their stability.
- Esterified or disproportionated rosins may also be used in the compositions of this invention.
- Esterified rosins are rosins which have been reacted with an alcohol which is preferably a polyol such as glycerol.
- Disproportionated rosins are rosins which have been treated by a catalytic process in order to improve their stability to oxidation. Mixtures of any of these types of rosin may be used in the compositions of this invention.
- the preferred rosin for use in the composition of this invention are fortified rosins.
- the preferred fortified rosins are those wherein the rosin has been reacted with from 5 to 50% of its own weight and generally about 10% by weight of a dienophile.
- Such rosins comprise a mixture of fortified and unfortified rosin. The two are normally used in combination in view of the fortification which would render the use of a product comprising fortified rosin only prohibitively expensive.
- the most preferred type of rosin is fortified tall oil rosin.
- the amine salt of the rosin acid may be produced by the neutralisation of any of the rosin or rosin derivatives described above. It may be prepared separately and added to the rosin dispersion, but more usually it will be produced in situ by the addition of sufficient amine to bring about the partial neturalisation of the acid content of the rosin.
- the amine salt is the salt of the rosin acid or acids present in the rosin component of the dispersions of this invention.
- the salt of the rosin acid may be produced by neutralising the acid either prior to or after its conversion to a rosin derivative.
- the neutralisation may be carried out using an amine having the formula: wherein substituents R1, R2 and R3, which may be the same or different, represent alkyl or alkenyl groups comprising from 1 to 4 carbon atoms or a hydrogen atom, with the proviso that at least one of the substituent is not a hydrogen atom.
- substituents R1, R2 and R3 represent alkyl groups and, most preferably, all three of these substituents represent alkyl groups.
- R1, R2 and R3 which represent alkyl groups may represent branched or straight chain saturated alkyl groups such as methyl, ethyl, or n- or iso- propyl, n-, sec- or tert- butyl groups or they may represent alkyl groups which contain one or more substituent groups such as hydroxyl, alkoxy, carboxy or amino groups such as 2, hydroxyethane groups or hydroxypropane groups.
- Particular amines which are useful in the composition of this invention include monomethylamine, dimethylamine, trimethylamine, monoethylamine, diethylamine, triethylamine, monopropylamine, dipropylamine, tripropylamine, monoethanolamine, diethanolamine and triethanolamine.
- the most preferred amine is triethanolamine.
- the amount of amine which is added to the rosin will be that which is required in order to produce the desired amount of amine salt.
- the amount of amine which is added will normally be sufficient to neutralise from 1 to 20%, preferably from 3 to 6% of the acid groups present in the rosin.
- the amount of amine salt will normally be such that the mixture comprises the same proportions of neutralised and nonneutralised rosin acids.
- the co-reactant component of the dispersions of this invention may be of any of the aluminium salts known to be useful in the sizing of paper such as aluminium sulphate, paper maker's alum Al2(SO4)3.18H2O, polyaluminium chlorides such as those having the formula Al(OH) x (SO4) y Cl z wherein x has a value in the range 1.35 to 1.65, y has a value of from 0.08 to 0.15 and z has a value of 3-(x+y), or those having the formula: Al n (OH) m Cl 3n-m wherein n has a value of from 1 to 20, m is less than 3n and is at least 2 and preferably at least 5.
- a particular type of polyaluminium chloride which is useful in the dispersions of this invention are those described in European Patent Application 145686 and those produced by the processes described in European Patent Application 181847.

- the preferred co-reactant for use in the compositions of the present invention are the aluminium chlorohydrates.
- the dispersions of the present invention may be prepared by simple admixture of the components thereof or by using any of the conventional techniques of the art.
- the dispersions may be prepared using the inversion technique.
- the rosin preferably a fortified rosin, optionally treated with para formaldehyde in the presence of a para toluene sulphonic acid to inhibit crystallisation, and optionally one which has been at least partially neutralised with an amine, may be melted and a stabilising agent or mixture of stabilising agents may then be added as a concentrated (e.g. 50% by weight solids) aqueous solution. Sufficient water is stirred in to form a creamy water-in-oil emulsion (e.g. 20 to 40% based on the weight of rosin).
- a stabilising agent or mixture of stabilising agents may then be added as a concentrated (e.g. 50% by weight solids) aqueous solution.
- Sufficient water is stirred in to form a creamy water-in-oil emulsion (e.g. 20 to 40% based on the weight of rosin).

- the preferred sources of ammonia or ammonium salt for use in the compositions of the present invention are the products obtained by the reaction of urea with sulphamic acid including all those products which are described in United States Patent 4025354.
- These modified ureas may be produced by combining urea with sulphamic acid and water.
- the parts by weight of water equal the parts by weight of urea plus sulphamic acid, although the urea may be treated with the sulfamic acid with more water or with little or no water.
- the urea-sulphamic acid solution may be heated to a temperature which causes a change in the pH for example to rise in the pH to at least about 7.5.
- the temperature affecting the pH may be higher.
- a temperature of about 212° and 235°F, preferably about 215° to 230°F will increase the pH up to at least about 7.9.
- the solution boils at the temperature which changes the pH and heating should be continued until after boiling has stopped to effect an irreversible pH change.

Accordingly, sulphamic acid at 0 25% by weight of urea produces a first stage product with an acidity of 4,300 ppm. As indicated, the amount of sulphamic acid added to the solution is not as important as its resulting acidity in defining the first stage product of the novel size composition of this embodiment.

- compositions of the invention my be employed as an internal size or as a surface size. Their use as an internal size forms a preferred aspect of the present invention.
- Internal sizing processes comprise the dilution of the concentrated composition with water and the addition of the diluted composition to a pulp suspension.
- the amount of size compositon employed is generally in the range 0.1 to 5.0% by weight of solids based on the weight of fibres in the pulp slurry.
- the emulsions may be used for sizing paper, including alumed paper.
