Description

Cellulosic filler for paper, tissue or paperboard products and also manufac turing methods therefor and paper, tissue or paperboard product containing such a filler or dry mixture used therefor

TECHNICAL AREA

The invention relates to a cellulose-containing filler for paper, tissue or paperboard products and to production processes therefor, and to a paper, tissue or paperboard product containing such a filler or dry mixture used therefor according to the preambles of claims 1, 39, 52 and 38, respectively.

TECHNICAL BACKGROUND

For millennia, cellulosic fibers made from various vegetable raw materials have been used as the raw material for the production of paper and cardboard. Today, almost exclusively cellulose fibers are used, which are obtained from wood. What they all have in common is that they are long-fiber products produced in a wet process. Due to the large fiber length is a good Composite achieved in the paper and cardboard, which leads to sheet formation and which is of mechanical importance of the highest importance. These long-fiber products are the basis of paper and board production; Without them, no paper or cardboard can be produced. Their bond leads to the necessary sheet formation. They can differ in the degree of purity and in the fiber structure (freeness ⁰ SR). Highly purified, lignin-free celluloses are known as well as lignin-containing fibers (groundwood, CTMP) and recycled fibers, which are obtained from waste paper and are accordingly still contaminated with various impurities.

Finely divided products such as native starch, calcium carbonate, kaolin or titanium dioxide wer¬ used for various reasons in the production process of paperboard and Papierfabri¬ ken. Due to their small particle size, these products are easily washed out of the paper web. Additional measures are needed to achieve retention in the paper web, at least to some extent. But this involves higher costs and other technological disadvantages. According to Lite¬ raturangaben can be found on high-speed paper machines (> 1500 m / min) currently despite polymeric retention agents often below 40% retention of fillers and pigments.

In addition to the above-mentioned cellulosic, relatively long fibers, special cellulosic fibers, which are usually comminuted by dry or wet grinding technologies, are added as additive for producing cardboard and paper to the pulp, to obtain higher volume or lower grammages, better formation, and better results to achieve faster drainage. These fibers have a significantly shorter fiber length than the above-described cellulosic cellulosic fibers. Their amount used is less than 10%. Their task is to influence the sheet formation of the long cellulose fibers so that the above-mentioned effects are achieved. The disadvantage here is the negative influence on the mechanical strength In the case of lignin-containing additives, the degree of whiteness in the finished product deteriorates.

THE INVENTION

In order to reduce the additive consumption and, if appropriate, to reduce the additive-related treatment requirement of the water produced during the production of paper, tissue or cardboard products, a filler with the features of claim 1, a process for its production with the features of claim 39, a corresponding paper, tissue or cardboard product according to claim 52 and a dry mix according to claim 38 proposed. Preferred embodiments and applications emerge from the subclaims.

The invention binds additives for paper, tissue or paperboard production to the cellulosic component of the filler, so that they also adhere to a considerable extent to the fibers in aqueous suspensions. It is also possible to use liquid substrates, such as wet strength agents or optical brighteners, which are used in the paper formulations anyway. Since these fibers are coarse enough to remain in the paper web without additional effort, the finely divided components adhering to the surface are also held in the paper web.

Compared with the dosage of pulverulent pigment and filler, the new development according to the invention gives better retention on the sheet former. The fixation reduces the amount of expensive additives and reduces the wastewater load. In addition, complex processes such as starch coking or size press are replaced by simpler processes in the paper mill. - A -

While "fiber loading" process requires a pretreatment with liquid calcium hydroxide and a reaction with gaseous carbon dioxide, the new development according to the invention provides stable coatings with simple mechanical processes.

Thus, a multifunctional filler having at least one additive is proposed, which u. a. can offer the following benefits:

I. Increased drainage and productivity 2. Improvement of theological properties (compared to wood pulp)

3. Improvement of the formation

4. Reduction of drying costs

5. Increased dimensional stability

6. Higher volume 7. Increased filler retention, in individual cases lower retention agent consumption

8. Improved sizing for hydrophobicity and oleophobicity

9. Increased whiteness and better printability (compared to wood pulp)

10. Higher opacity

I 1. Higher strengths 12. Better effect of the optical brightener in the line and better printability

13. Biocide equipment

14. Flame retardancy

15. Antistatic properties

16. Cationization and adaptation of the zeta potential 17. Higher affinity to dyes

18. Higher solids content

19. Reduction of qualitative variations in recycled paper Insofar as the filler according to the invention comprises cellulose, lignoceilulose or microcrystalline cellulose (ie a cellulosic component), this also means cellulosic precursors or intermediates which also comprise other herbal ingredients, such as protein, protein, starch and / or mineral constituents and other. It is therefore not absolutely necessary to drive too far a chemical treatment of the vegetable raw material. Rather, vegetable ingredients may be included in the cellulosic component, the proportion of which should not exceed 25% of the total cellulosic component.

The particle sizes of the cellulosic component will preferably be limited to not more than 1 mm particle size, preferably not more than 0.5 mm particle size, with no restriction being required for smaller particle sizes, since nanoscale particle sizes can also be used successfully.

If the additives are used in particulate form, the particle sizes are preferably not more than 0.1 mm, preferably not more than 0.05 mm. Again, a limitation of the particle size down is not required. Rather, care must be taken that the particle size of the additives used is generally lower, preferably considerably less than the particle size of the cellulosic component.

The mass ratio between the cellulosic component and the additive component is preferably not less than 1 to 10 and particularly preferably not less than 2 to 10. No limitation is required in the direction of relatively large mass ratios, since in some circumstances very small amounts of additive may suffice. to achieve the desired effect in paper, tissue or board production. Otherwise, it is also possible to apply the additives in several layers to the particles of the cellulosic component. This makes it possible to achieve very small mass ratios of cellulosic component to additive component. As additives, as mentioned in more detail below, not only additives in pure form come into consideration. Rather, raw materials containing the additive can also be introduced into the production process of the filler according to the invention, so that the raw material preparation and the fixing or coating of the additives on the particles of the cellulosic component take place in one working process. Thus, for example, starchy raw materials such as soft wheat semolina, oat bran fractions, and extruded or cooked pregelatinized starches can be used to increase the strength of the paper or board on the one hand or the internal bond between fiber and coating on the other hand Furthermore, nanodisperse celluloses, for example based on a microcrystalline cellulose, can be used in order to provide a carrier for coating compositions, for example for optical brighteners, to additives such as polyvinyl alcohol, spray starch and CMC at least partially replace and improve the printability.

With the invention, a multiplicity of differently acting fillers for paper, tissue or board production can be realized. The preferred embodiments are described below:

The following fillers have the common concept of using cellulose fibers, in particular those of the applicant, as a carrier for traditional papermaking additives, in order to increase the effectiveness of the additives, to reduce their consumption and to reduce COD wastewater loads:

1) A novel sizing compound consisting of fibers and a sizing complex that enhances the hydrophobicity and / or oleophobicity of the papers and cardboards, the durability and uniformity of sizing, and the retention of the sizing agent in sheet formation. Another object of the invention is a production process for sizing compounds. The one Sizing compound provides an improved price-performance ratio for sizing.

2) A novel mineral compound consisting of fibers and minerals (fillers, pigments). The degree of whiteness and light fastness of the fibers used is markedly improved by the surface modification, which makes the use even in very light cardboard and paper possible. The invention relates to a lightweight filler, which is made of fibers and mineral be¬ for the production of paper and cardboard. The lightweight filler can reduce the volume of the paper, the machine speed and the filler

Increase Retention.

3) A novel starch compound which consists of fibers and native or cationic starch and can increase the strength values (mesh burst strength, PIy Bond ply strength, Tear Index, Tensile Index, tearing length,...) With identical grammage, or one Reduction of the grammage without strength losses zuiässt. The use should preferably, but not exclusively, take place in the wet end area. The starch on the fiber may be partially pregelatinised or homogenized with the fiber or in turn consist of starch mixtures. The modification of the fiber with starch leads to an improvement of the mechanical strength of the fiber composite in the end product. The object of the invention is a better retention of the starch in paper and cardboard, especially in recycled pulp with high anionic freight and high mineral content, in order to provide paper and cardboard with a higher strength. Another object of the invention is the production of a new type of festig¬ keitssteigenden additives, wherein fibers are reacted in the high-consistency range or dry with starch or pregelatiniert. 4) A novel biocide compound consisting of fibers and a biocide complex. The biocide may be immobilized on the surface of the fiber. The biocide compound can be used, for example, for corrugated base papers and for gypsum fiber boards in the wet-end area.

5) A novel brightener compound, which consists of fibers or microcrystalline colloidal cellulose and may contain an optical brightener. The brightener may be immobilized on the surface of the fiber or in a cellulose gel. The fiber may be bleached in the presence of common bleaching agents such as hydrogen peroxide, oxygen or ozone. The preparation may further contain powdery or liquid brighteners, as described as an optical brightener for lignocelluloses.

6) A novel antistatic compound, which consists of fibers and an electrically dissipative, antistatic additive. The antistatic additive may be immobilized on the surface of the fiber.

7) A novel cationic fiber compound, which consists of fibers and a cationizing agent and serves to adjust the zeta potential in cardboard and paper.

8) A novel flame-retardant fiber compound which consists of fibers and a flame retardant agent and serves to adjust the low flammability in cardboard and paper.

9) A novel liquid resin-fiber compound, which consists of fibers and a liquid resin or a gel and serves to adjust the strength in Karto¬ nagen and papers. Embodiment 1 - Sizing compound

Laboratory sheets were prepared at 6.00 g at 35 ° SR and a concentration of 6 g / 4 liters. The handsheets were dried in a drying oven at 125 ^° C. for 2 hours and conditioned at room temperature for 4 hours. The drop test was carried out as a rapid test with 75% formic acid. Especially when tested with the Emtec Penetration Tester and the Cobb 300 value, a significantly improved sizing result is clearly evident.

The high proportions of ash in all fractions show that the mineral components are bound to a high degree on the surface of the fiber particles. In the case of a purely physical mixture, mineral particles are predominantly found in the fines content of <32 μm. Exemplary embodiment 5.2 - mineral compound

Mullen mixers (MM) and Nara Hybridizers (NH) were used to make various compounds with inorganic fillers and pigments. The titanium dioxide pigment used was a rutile pigment from Kronos with the designation "Kronos 2050".

20 g of compounds were stirred in a Waring Blender with 200 ml of water for 1 minute, then diluted to 2 L of water and stirred with magnetic stirrer for 5 minutes, then filtered through a 45 μm PP Tissue fabric (air flow 440 L / m ² min). The Asche¬ values were determined in a muffle furnace at 850 ⁰ C.

Embodiment 6 - Brightener Compound

Ciba Pfersee optical brighteners were used to increase the brightness of the ARBOCEL BER 40 cell phone. These components are in turn suitable in the mixture for the color lightening of celluloses and MCC, in particular for reducing the b * value. The brightness values achieved allow a reformulation of the pulp with regard to "light fastness" and formulation costs.

working methods

The freeness was determined according to Schopper Riegler according to ISO 5267/1. In individual cases, the freeness at 35-750 ml drainage with the DDJ drainage meter was gegenge¬ checks, with 1000 ml for 60 seconds at 3.0% TS and 20 ⁰ C on 60 mesh ⁰ SR sieve. The amount of filtrate [ml] after 60 seconds corresponds to the CSF value [ml].

100 cm ² handsheets were made on a Rapid-Köthen sheet according to DIN 54358 / ISO 5269/2. For laboratory papers with the same grammage, the bursting pressure was determined as the Müllen Burst Index.

The whiteness [% ISO] was measured as a reflection at 460 nm using the Minolta CM 3600 colorimeter, CIE or Hunter color values.

The ash content was determined in a muffle furnace at 450 ^° C. (after 5 hours) or 850 ^° C. (after 8 hours). The starch content was determined by an iodometric titration according to Tappi T 419 om-91. Cobb value was determined according to ISO 535, EN 20535 and Tappi T441, as well as with the Emtec Penetration Tester.

Drainage and retention were determined with Mytek drainage meter. In the case of the water removal measurement, the fiber suspension is filled into the stirred chamber and subjected to shear after addition of additive. During the measurement process, the suspension is filtered on a sieve and the amount of filtrate gravimetrically over the dewatering time. Stirring speed 300 rpm at 2% TS corresponds to the tests in the carton area (gray area).

In the retention measurement, the fiber suspension is dewatered on a sieve with constant stirring - without the formation of a filter layer. By determining the solids content in the filtrate or after drying and ashing, it is possible to calculate the total and filler retention.

Various wood fiber materials were coated with very finely divided mineral additives such as titanium dioxide or calcium carbonate by rubbing mechanical forces (average particle size of the minerals: <10 μm). The fibers used were among others.
