Definitions

  • This invention relates to petroleum wax compositions and, more particularly, to petroleum wax coating compositions widely used in forming protective coatings for wrapping paper and paperboard in the production of low-cost cartons for liquids.
  • the petroleum industry generally classifies petroleum waxes in three main categories, namely, (1) parains; (2) intermediate; and (3) microcrystalline waxes.
  • Other classes of waxes are known such as the scale waxes and slack waxes; these are low-cost crude waxes.
  • the paraflins are predominantly the normal paraflns, i.e., straight chain saturated hydrocarbons with minor amounts of isoparaflins.
  • the microcrystalline waxes are predominantly cyclic TAB LE I Paratnn Inter Mierocrysmediate talline Melting Point Range, ASTM D127, F 120-160 130-160 130-180 Molecular Weight Range... 340-400 S60-550 500-600 Density Rai 0. 80-0. 917 0. 85-0. 93 0. 89-0. 94 Gravity ASTM D287 AP 0 F 35-60 30-55 30-50 Distillation, Vacuum Corrected to 760 mm.

  • a typical parain wax has the following properties:
  • the upgrading of waxes by the addition of additives thereto has sought to improve the creased barrier properties of the coated material.
  • the property of a coating wax employed, for example, in the coating of paper and paperboard, in the manufacture of food wrappers and paper cartons, to minimize passage of moisture vapor through the creased or folded coated paper and paper: board is a most important factor in the commercial acceptance of that coating wax.
  • a standard test widely used in the wax coating art for measuring this property is the creased moisture vapor transmission rate (referred to herein as creased WVTR). This test is described in TAPPI 465 creased WVTR.
  • sealing strength values are determined by the standard Socony- Vacuum Seal Tester. Two coated specimens which are sealed together under the predetermined temperature, pressure and dwell time specified in the test procedure are pulled at 3 in./min. with a 100 gram load. The values given are the weight in grams required to pull apart the two coated specimens. In the case of the test results given in this specification, the test specimens are each rectangular, 12 inches long, 2 inches wide, arranged in superimposed relation with a l-inch seal at a temperature of ZOO-250 F., pressure of 6-10 p.s.i.g. for a dwell time of 1A: to 1.5 minutes.
  • Grease resistance is a measure of the time required for a drop of the specilied grease to penetrate through the coated, uncreased test specimen.
  • the grease used in the test results given herein was Wesson Oil applied at ambient temperature and maintained at F. until failure of the coating.
  • paraffin waxes are upgraded by blending therewith from 10% to 30% of a polybutene-l resin having a molecular weight of from 100,000 to 200,000 and an isotactic content of from 50% to 70%.
  • this invention involves wax coating compositions consisting essentially of a paraffin wax blended with from 10% to 30% by weight of a polybutene-l resin having a molecular weight of from 100,000 to 200,000 and an isotactic content of from 50% to 70%.
  • the drawing accompanying this specification and forming a part thereof is a graph showing the creased WVT'R values plotted against the percent concentra-tion of five different polybutene-l resins having the different isotactic contents indicated on the graph.
  • curve A shows the creased WVTR values for the base paraffin wax, which is a typical parain wax having the properties hereinabove given for such wax.
  • Curve B is the graph for a blend of this paraflin wax with a polybutene-l resin having a moleucular weight of 186,000 and an isotacticcon- -tent of 51%.
  • Curve C is the graph for a blend of this paralin wax with a polybutene-l resin having a molecular weight of 145,000, and an isotactic content of 57%.
  • Curve D is the graph for a blend of this parain wax with a polybutene-l resin having a molecular weight of 151,000 and an isotactic content of 64%.
  • Curve E is the graph for a blend of this parain wax with a polybutene-l resin having a molecular weight of 190,000 and an isotactic content of 68%.
  • Curve F 4 is the graph for a blend of this paraffin wax with a polybutene-1 resin having a molecular weight of 67,000 and an isotactic content of 92%.
  • the creased WVTR value for the base parain wax is 15.5.
  • the blending therewith of polybutene-l resin having a molecular weight of 186,000 and an isotacticity of 51% markedly improves the creased WVTR values; for a 20% concentration of this polybutene-l resin the creased WVTR value is reduced to 1.9; and for 25 concentration to 1.0.
  • ⁇ of polybutene-l resin having an isotacticity of 57% and a molecular weight of 145,000 a concentration of 20% reduces the creased WVTR value to 7.0, and for 25% concentration to 2.5.
  • vEmploying a ⁇ polybutene-l resin having an isotacticity of 68% the creased WVTR value (16.8) for 10% concentration is, slightly higher than the creased WVTR for the base wax; for a concentration the value is 12.6 as compared with 15.5 for the parain base wax; and for a 30% concentration the creased WVTR value is 2.7, the same as for the polybutene-l resin having an isotactc content of 64%.
  • isotactc is used in its conventional sense to mean the material in the polymer remaining after extraction with diethyl ether; the isotactc material is substantially insoluble in hexane and naphtha.
  • the diethyl ether extraction removes the amorphous or atactic material (which is the material soluble in hexane and naphtha) and leaves a polymer containing the isotactc material.
  • the polybutene-l resin employed in forming lthe wax blends of the present invention can be prepared by polymerizing butene-l using a Ziegler type catalyst and conducting the polymerization under conditions to produce a polymer having the desired isotactc content of from 50% to 70% and desired molecular weight of from 100,000 to 200,000.
  • any of the known Ziegler catalysts can be used; for example, catalysts obtained by reaction between compounds of metals of Group IV-A (titanium, zirconium, hafnium or thorium), V-A (vanadium, columbium or tantalum), VI-A (chromium, molybdenum, tungsten or uranium) with alkyl compounds of aluminum or a metal of Group II (beryllium, magnesium, calcium, strontium, barium, Zinc or cadmium).
  • Group IV-A titanium, zirconium, hafnium or thorium
  • V-A vanadium, columbium or tantalum
  • VI-A chromium, molybdenum, tungsten or uranium
  • alkyl compounds of aluminum or a metal of Group II beryllium, magnesium, calcium, strontium, barium, Zinc or cadmium
  • Polybutene produced by p0- lymerization using stereospecic catalysts such as
  • polystyrene-l having the desired molecular weight and isotactic content.
  • Hydrogen can be introduced into the polymerization reaction mixture to control the molecular weight and percent isotacticity.
  • Polybutene-l polymers having an isotactc content of from 50% to 70% and a molecular weight of from 100,000 to 200,000 produced by any known procedure can be used.
  • Polybutene-l resins having the above noted isotactc contents and molecular weights blend readily with the paraffin wax.
  • polybutene-l with the paraffin wax can be effected in any known or desired manner. A typical procedure for effecting such lblending is described below.
  • a three-necked ask equipped with an electric drive stirrer, a thermometer, and a nitrogen inlet tube is charged with a measured amount of the wax.
  • the wax is heated under nitrogen with moderate stirring until a clear liquid results.
  • a charge of the polybutene-l resin having the molecular weight and isotacticity and in amount all as herein disclosed.
  • the mixture is heated to a temperature above the melting point of the wax and stirred to assist solution.
  • the mixture can be maintained under a continuous blanket of nitrogen during the heating and stirring, if desired, and particularly when the heating is carried out under higher temperatures than 150 C.
  • the polybutene-l charge is completely dissolved in the wax in approximately one-half hour; this is evident upon visual inspection. Desirably, however, heating of the blend is continued for an additional onequarter hour to insure complete dissolution of the resin in the wax.
  • the blend is thereupon allowed to cool to ambient temperature.
  • Table III which follows gives the grease resistance of blends of parain wax with a polybutene-l resin having a ⁇ nolecular weight of 150,000 and an isotactc content of 64% (hereinafter referred to as PB-l) in concentrations of 20% and 30%. This test was carried out with Wesson Oil applied at ambient temperature and maintained at F. on the uncreased paper.
  • the wax blends embodying the present invention are eminently satisfactory for use in existing coating equipment. They can be employed in a'll elds where Wax coatings of superior creased barrier properties, heat seal strength, or good grease resistance, ndapplication.
  • the blends of this invention in the molten state, can be applied Iby known coating techniques to foil, parchment, kraft, glassine, chipboard and other paper stocks to produce packaging materials having an attractive gloss and exceptionally good creased vapor barrier.
  • a petroleum Wax blend consisting of a parain wax distilling Within the temperature range of about 750-810 6 F. and from 10% to 30% by weight of a polybutene-l resin having a molecular weight of from 100,000 to 200,00 and an isotacti-c content of from to 70% by Weight, said 4blend having creased water vapor transmission rate value less than Ithat of said parafln Wax.
