Definitions

  • the present invention relates to novel viscosity regulating substances for regulating the viscosity of paper coating mixes, and to the use of such substances.
  • the object of the present invention is to enable the interchange of coating mixes in continuous paper coating processes without substantial change in the viscosity of said mixes at the transition from one mix to the other and/or the mixing of the mixes one with the other.
  • Paper is coated by applying an extremely thin layer of coating mix to a paper web.
  • the purpose of the coating is to improve the properties of the paper, particularly with regard to uniformity of surface, and its ability to accept inks, laquers etc from the printing press.
  • Such mixes today comprise finely ground kaolin, dispersant, and water, or chalk, dispersant, water.
  • Mixes have also been proposed, and prepared, that comprise calcium sulphate dihydrate (gypsum) dispersant and water.
  • gypsum calcium sulphate dihydrate
  • the acid addition salt is prepared by reaction with sulphuric acid, phosphoric acid, halogen hydrochloric acid, nitric acid, perchloric acid, aliphatic, alicyclic, aromatic and heterocyclic carbonic and sulphonic acids.
  • such salts are hydrochlorides, sulphate, hydrogen sulphate, phosphate, hydrogen phosphate, nitrate, formiate, acetate, propionate, succinate, glycolate, gluconate, heptonate, lactate, tartrate, citrate, oxalate, ascorbate, maleate, hydroxy maleate, bensoate, p-amino bensoate, p-hydroxy bensoate, salicylate, p-amino salicylate, picrate, diethylene triamine pentaacetate (DTPA), ethylene diamine tetraacetate (EDTA), nitrilo triacetate (NTA), hydroxy ethyl imino diacetate, bis (hydroxyethyl) gluconate.
  • DTPA diethylene triamine pentaacetate
  • EDTA ethylene diamine tetraacetate
  • NTA nitrilo triacetate
  • the alkyl amines used in the group preferably comprise primary alkyl amines, such as methylamine, ethylamine, propylamine, 1-methyl ethyl amine, butyl amine, 1-methyl propyl amine, 2-methyl propyl amine, pentyl amine, 3-methyl butyl amine, 2-methyl butyl amine, 1-ethyl propyl amine, 1-methyl butyl amine, 1,1-dimethyl ethyl amine, 1,1-dimethyl propyl amine, although they may also comprise secondary, tertiary, and quarternary alkyl amines, such as dimethyl amine, diethyl amine, trimethyl amine, tetramethyl amine.
  • primary alkyl amines such as methylamine, ethylamine, propylamine, 1-methyl ethyl amine, butyl amine, 1-methyl propyl amine, 2-methyl propyl amine, pentyl
  • the product is prepared by mixing a solution of an alkyl amine with a solution of acid which will react to form the intended acid addition salt. It is irrelevant in this respect whether one solution is added to the other, or vice versa.
  • the respective solutions may have the form of a concentrate or a solvent solution of the compound concerned.
  • the ratio of amine to acid is from 1 to 4, depending upon the degree of substitution desired.
  • the reaction between alkyl amine and acid takes place instantaneously, whereafter the product can be filtered off (when the reaction takes place in a non-dissolving solvent) or can be used direct, in solution.
  • the follwoing systems were prepared in a similar manner: A series of experiments was conducted on the basis of the above substances, in which there was prepared a first kaolin mix comprising 100 parts of dry kaolin, 50 parts of water, 0.35 parts of 100%-Dispex®, and NaOH. The pH of the mix was 8.5. A suspension was then prepared over a period of one hour, by adding to the mix 9 parts of latex DOW 685, 1.2 parts of CMC (carboxy methyl cellulose) and water to a viscosity of about 1000-1500. The pH of the suspension was adjusted to 8.5, to obtain a viscosity of about 1500 cps, dry solids content 55-58%. Peripheral data concerning different starting kaolin mixes is given in Table 1 below, left column.
  • a further gypsum based mix was prepared from 100 parts dry gypsum, 1.5 parts CMC, 9 parts latex DOW 685, NaOH to pH 8.5, and water, there being obtained a mix with DS 64.4%, viscosity 950 cps.
  • Various amines according to the aforegoing were added to 400 g of the kaolin mix thus prepared, in the quantities set forth in Table 1, whereafter 30.1 g of the gypsum mix were added and the viscosity of the resultant mixture was measured. The viscosity was also measured after adding the amine.
  • the results obtained when adding the gypsum based mix are set forth in the right column of Table 1 below.
  • the present invention has also been tested on a semi-industrial scale in apparatus having a volume of 25 litres.
  • the apparatus comprised a machine tank having a volumetric filling capacity of 15 litres, a filter, and a buffer tank provided with an outlet leading to the machine tank and to the "coating station", i.e. the apparatus simulated the coating of a paper web by taking out 1 litre of mix per minute.
  • the volume circulated was 7 litres and the flow rate 10 litres per minute.
  • the system was filled with a mix 1, whereafter the mix was pumped around the system and "coating commenced".
  • Table 2 The results set forth in Table 2 were obtained when testing a conventional kaolin coating mix (mix 2), 100 parts of kaolin, 0.35 parts Dispe#N40, 1.2 parts of CMC FF5, and 9 parts of latex DOW 685, DS 56-59%, pH 8.5-9, and a gypsum--based coating mix (mix 1) comprising 100 parts of dry gypsum, dihydrate, 1.5 parts CMC, and 9 parts of DOW 685, DS 60-65%, pH 8.5-9, without further addition of a compound according to the present invention.
  • a conventional kaolin coating mix (mix 2), 100 parts of kaolin, 0.35 parts Dispe#N40, 1.2 parts of CMC FF5, and 9 parts of latex DOW 685, DS 56-59%, pH 8.5-9
  • a gypsum--based coating mix (mix 1) comprising 100 parts of dry gypsum, dihydrate, 1.5 parts CMC, and 9 parts of DOW 685, DS 60-65%
  • Table 3 discloses the results obtained when adding to mix 1 (the gypsum mix) 0.4 parts of propyl amine phosphate, calculated as amine.
  • kaolin-based mix By kaolin-based mix is meant here, and in the aforegoing, a mix in which the pigment fraction contains more than 50% kaolin. Kaolin mixes that contain 60% kaolin and 40% gypsum are thus known in the art.
  • chalk-based mixes is meant a mix that contains more than 50% chalk
  • gypsum-based mixes is meant a mix that contains more than 50% gypsum.
  • the pigment fraction need not be totally based on one pigment.
