Definitions
- Coating composition comprising hydrolysed wheat proteins
- the present invention relates to a paper or paperboard coating composition comprising a modified starch and a hydrolyzed wheat protein as well as the method for obtaining such a composition.
- the invention also relates to a process for coating or bluing paper or board using such a composition, the coated paper or board thus obtained.
- the invention finally relates to the use of a hydrolysed wheat protein in the replacement of the latex in a paper or paperboard coating composition.
- Coating also known as coating, is a finishing step for paper or board which makes it possible to give a sheet of paper or a cardboard a number of properties, such as opacity, gloss, whiteness or to improve printability for printing processes such as offset or gravure.
- a composition called coating color is applied to the surface of the paper or board.
- This composition generally comprises at least one inorganic filler or pigment, at least one binder and other additives such as in particular dispersants, rheology modifiers, lubricants, optical brighteners or anti-foams.
- Latex typically synthetic styrene-butadiene type latex is the most widely used binder. Its function is to allow the cohesion between the different elements of the composition and to bind them to the fibers.
- Synthetic latex is produced from petroleum resources that are by definition non-renewable. In order to reduce the number of chemicals used in this industry, to decrease the consumption of petroleum products as well as the costs, the replacement of the latex in the coating sauces represents a potential market but also a major technical challenge. Indeed, it is very difficult to maintain the performance of a coating color by reducing the proportion of synthetic latex used.
- coating colors are intended to be applied to the surface of paper or cardboard in very thin layers and at very high speed. They are applied by means of a filamented blade or rod which exerts very large shear forces on the surface of the paper.
- these shearing forces cause not only at the level of the application zone, turbulences responsible for defects in the deposit called “baves” or “pearls” but also an increase the pressure exerted on the paper thus increasing the risk of breakage and therefore potentially production downtime.
- the prior art proposes coating compositions having a low solids content.
- the reduction of the dry matter of the composition (and therefore the increase in the water content) in order to reduce the viscosity is not an advantageous solution in the present application.
- the coating color has a natural tendency to transfer all or part of the water and the water-soluble parts it contains into the paper sheet. This has several consequences, the first of which is the weakening of the paper or the cardboard which by the excess of water, can lose its integrity and cause a breakage of the produced paper and thus hours of stoppage of production. The second is loss of gloss of the paper observed following the migration of the water-soluble parts of the coating color into the paper.
- This migration leads to a third consequence which is the weakening of the cohesion of the paper layer causing problems during printing. For example, there may be mentioned deposits of fibers or mineral fillers originating from the layer on the blankets during offset printing. The last consequence of this excess of water of the coating composition is the increase of the energy and / or the time necessary for drying the obtained paper or board.
- the advantage of a coating color having both a high solids content and a low viscosity beyond the resolution of the above-mentioned problems is the low need for the coating color.
- a coating of low viscosity coating would also have the advantage of allowing a very high speed coating which is a very clear industrial advantage.
- the invention relates to a coating composition of paper or paperboard having a solids content between 45 and 80%, preferably 50 and 78%, more preferably 55 and 75%, comprising:
- composition according to the invention comprises in parts per 100 parts by weight of mineral filler:
- binders 1 to 99 parts of binders, preferably 1 to 50 parts, more preferably 1 to 15 parts, and
- wheat protein refers to a water insoluble protein fraction, extracted from wheat flour wet and then dried, also called wheat gluten.
- wheat proteins having an average molecular weight of between 7 and 1000 kDa are obtained by hydrolysis according to methods well known to those skilled in the art [Anfinsen, CB Jr. (1965) Advances in Protein Chemistry: v.20. New York and London: Academy Press].
- the hydrolysis can be thermal, acidic or enzymatic. Enzymatic hydrolysis is preferred.
- modified starch in the sense of the present invention any starch that has been chemically or physically treated.
- esterification in an alkaline medium for the grafting of functional groups in particular C1-C6 acyl (acetyl), hydroxyalkyl C1-C6 (hydroxyethyl, hydroxypropyl), carboxymethyl, octenylsuccinic. Mention may in particular be made of starches modified with sodium carboxymethyl;
- Suitable modified starches include, but are not limited to, pregelatinized starches, low viscosity starches (e.g., dextrins, hydrolyzed starches, oxidized starches), stabilized starches (e.g., starch esters, ethers, and the like). starch), crosslinked starches and starches which have received a combination of treatments (e.g., crosslinking and gelatinization) and mixtures thereof.
- Dextrins are the preferred modified starches.
- the term "dextrin" means a modified starch obtained from native starch by dextrinisation, typically the dextrins according to the invention are not subjected to any other modification, in particular chemical modification.
- the average molecular weight is expressed in Dalton and can be determined by those skilled in the art by steric exclusion chromatography coupled with a MALLS type detector (Multi Angle Laser Light Scattering).
- the preparation of a sample may be carried out by solubilizing 50 mg of dry mass of a modified starch and in particular of dextrin in a solvent consisting of a mixture of 90% (v / v) of DMSO (dimethyl sulfoxide) in a solvent. deionized water containing 0.1% (w / v) sodium nitrate. After stirring overnight, the mixture is preheated for 1 hour at 105 ° C.
- the coating colors were made as in Example 1 according to the formula in Table 3 in which the synthetic latex is replaced by proteins at 14% (R5), 30% (R6) and 43% (R7).
