Definitions

  • the present invention relates to a method for manufacturing paper and more particularly packaging paper and cardboard.
  • the raw paper pulp consisting essentially of cellulose fibers is put in the form of a dilute aqueous suspension which is brought into the headbox of the paper machine from where it is distributed on a filter cloth on which the sheet is formed. of paper. This sheet is then wrung and dried.
  • the qualities and properties of the paper obtained are determined in particular by the operating conditions of the paper machine, the raw pulp, the various additives that are added to the suspension before the sheet is formed and also the products that are coated. on the sheet of paper after the filter cloth.
  • the present invention relates more particularly to the products which are added before the sheet is formed.
  • Cellulose fibers come from raw paper pulp but often from recycled paper or cardboard, sometimes mixed with raw pulp.
  • British patent GB 2,015,614 describes a process for manufacturing wrapping paper and cardboard grooves in which cationic starch and a basic aluminum polychlorosulfate are added to the fiber suspension before the headbox. , or aluminum sulfate.
  • the amount of cationic starch does not exceed 0.4% of the weight of cellulose fibers. It is known that cationic starch contributes to the mechanical strength of the paper and it would be useful to be able to put much more than 0.4% in the suspension and especially to retain this starch in the sheet formed.
  • Starch is very hydrophilic and if we exceed an amount of 0.5% we can no longer form the sheet of paper on the filter cloth except by greatly reducing the productivity of the paper machine. According to the present invention, a new process has been found which makes it possible to use amounts of starch greater than 0.5% in the headbox of the paper machine.
  • the suspension containing the cellulose fibers can be raw or bleached pulp, or a mixture of raw pulp and bleached pulp. Very often we add used paper and cardboard to the previous mixture.
  • Cationic starch is a mixture of one or more products marketed under the generic name of cationic starch. These products are for example those described in KIRK OTHMER, 3rd edition, Vol. 21 page 503. The amount is advantageously between 0.5 and 5 parts per 100 parts of cellulose fibers, and preferably between 0.7 and 2.
  • the quantity of polychloride of aluminum expressed as A1 2 0 3 to be used is preferably between 0.02 and 0.3 parts by weight per 100 parts of cellulose fibers.
  • products a and b can be added in any order and at any place before the headbox of the paper machine, it is preferred to add poly aluminum chloride after the cationic starch. It is also preferred that the poly aluminum chloride be added as close as possible to the headbox.
  • Cellulose fibers can also be added to the suspension before the sheet is formed, and in addition to products a and b, other products such as dyes.
  • the cationic starch it is possible to add, in addition to the cationic starch, one or more products chosen from polyacrylamides, polyethyleneimines, carboxymethylcellulose, urea-formaldehyde resins, melamine-formaldehyde resins, resins aminopolyamide-epichlorohydrin, polyamide-epichlorohydrin resins.
  • these products are used in addition to the cationic starch and in the same quantities.
  • any bonding agent is suitable, it is advantageous to use rosin or a mixture of one or more products chosen from dimeric ketene alkyls and their derivatives, fluorinated phosphates, fatty chain carboxylic acid anhydrides, certain polyurethanes, styrene / maleic anhydride copolymers.
  • dimeric ketene alkyls and carboxylic acid anhydrides It is preferred to use dimeric ketene alkyls and carboxylic acid anhydrides.
  • the quantity to be used depends on the desired properties of the paper or the cardboard.
  • the amount is less than 10 parts per 100 parts of cellulose fibers and preferably between 0.1 and 2 parts.
  • the sizing agent is added before the poly aluminum chloride.
  • Another advantage of the invention in addition to the good mechanical properties obtained, is a large reduction in the matter in suspension in the water collected under the filter cloth during the formation of the sheet.
  • Another advantage of the invention is greater productivity of the paper machine and better internal cohesion. All these advantages will appear in the examples. The following examples illustrate the invention.
  • Example 2 The procedure is as in Example 1, but in addition, before the headbox, an aluminum polychloride is added in a proportion of 0.15 parts expressed as A1 2 0 3 per 100 parts of cellulose fibers.
