  • the starting aqueous silica' sol carfrangeffrom 10 to 60 percent by weight of discrete, dense colloidal particles of amorphous silica;
  • the average particle diameter can range from 3 to 150 millimicrons and can have an average surface area from 20 M /g. to 1,000 M /g. It is preferred that the starting aqueous silica sol be from 30 to percent by weight of discrete, dense colloidal particles of amorphous silica.
  • the preferred particle diameter should range from 16 to 22 millimicrons and have an average surface areafrom l35 to 190 M /g,
  • Nalcoag 1034A contains less than 600 ppm of sodium, Na, calculated i as Na O, and ppm of chloride, Cl, as combined chloride and sulfate.
  • the quaternary ammonium compound has the formula:
  • R R are methyl R is methyl or a C,,-C long hydrocarbon chain; R is a C,;--C long hydrocarbon chain; Xis an anion selected from the group consisting of chloride, bromide, iodide, and hydroxide.
  • Another quaternary ammonium compou nd that has In the formulae above the nitrogen substituent groups are chosen with the viewpoint of providing water solubility or having some degree of water dispersibility provided by 2 or 3 methyl coupled with 1 or 2 long hydrocarbon chain groups to provide the necessaryfat'ty residue for the coating.
  • operable compounds are those where R, or R R, are lauryl, plamityl, stearyl, oleyl, octyl, caprylyl, etc., and these may be similar or dissimilar.
  • Preferred substituents for R and R are quaternary amines derived from mixtures of fatty acids that occur in various fats and oils such as coconut oil, hydrogenated tallow, hydrogenated castor oil, etc. Specific examples of preferred quaternary compounds include:
  • Lauryl trimethyl ammonium chloride Dicocodimethyl ammonium chloride .Di(hydr'ogenated tallow) dimethyl ammonium chloride Tallow trimethyl ammonium chloride An additional operable compound not consonant with the formulae supra, is tricaprylmethyl ammonium chloride. Additionally operable are the alkyl trimethyl amthe outward'nitrogen, which is part of the second coating of quaternary. 7
  • the starting silica aquasols are preferably double deionized sols, and it has been found highly advantageous to add a hydrophilic bridging solvent such as a lower alkanol and a preferred alkanol is isopropanol.
  • a hydrophilic bridging solvent such as a lower alkanol and a preferred alkanol is isopropanol.
  • isopropanol utilized is preferably about 3 l% by weight of the water in the aquasol.
  • the lower alkanol e.g., isopropanol
  • the addition of the alkanol helps stabilize the quaternary and to lessen gelation and precipitation tendencies.
  • the mixture is stirred from about 1-60 minutes.
  • the first layer Asthe first layer goes on, it neutralizes any charge (negative) on the silica particle and imparts an organophilic surface. At this point, the sol becomes less stable and there is a tendency for gelation or precipitation to occur. There is a decided thickening visually noticeable.
  • the lower alkanol solvent which is a requisite acts to solubilize or disperse the coated sol in water.
  • As the second coat becomes a layer a different charge (positive) is imparted to the particle and the sol is restabilized.
  • the second layer is oriented with its organophilic portion toward the surface and its ionic portion toward the solvent.
  • step one the lower alkanol solvent is added to the quaternary amine in excess;
  • step two the lower alkanol solvent is added to the quaternary amine in excess;
  • the colloidal silica is added with sustained mixing into 7 deionizedsol withthe properties like Nalco 1034A (see Table l).
  • a silica sol of this type has little charge on its surface and tends to be more stable in the critical period during the application of the firist coating or in the intermediate stage of manufacture.
  • Alternative commercial sols may, be used, but optimum results are obtained by utilization of sols having -190 M /gram average surface area.
  • the system may thicken, but the alcohol prevents gelation or precipitation until the system thins out when additional silica sol is added.
  • the amount of the quaternary in'jrelation to the silica depends uponthe particle size of the colloidal silica.
  • the ratio of SiO; to quaternary will be from 25 to l to 2 to l, and more often will be from 3:1 to 10:]. For an average particle diameter of 20 millimicrons a ratio of about ⁇ to l is typical.
  • the present formulation uniformly requires a layer of quaternary which is physically sorbed and contains a molecular double layer.
  • layer one the innermost layeraround the silica
  • FIG. 1 represents results from antistat tests at different percentages of silica where the half-life time expressed in seconds was measured according to the procedure of Example III-A.
  • the antistatic effect is due to the quaternary component and is measured and observed on fabric samples treated by dip methods.
  • the antisoil effect is due to the silica component and is measured on fabric samples treated by spraying.
  • EXAMPLE 11 Preparation of Double Coated Silica Sol To 33.6 grams of Arquad 2C-75 was added 10.5 grams isopropanol followed by 150 ml of Nalcoag 1050 silica sol diluted with 90 grams of water. The preparation was made with good mixing throughout the addition steps. The product became very thick during the Nalcoag 1050 addition but'thinned out again after a period of a few minutes. The product is stable over a one-year period.
  • Statis electricity tests were performed using the Stati'Tester, Model 169, from Most Associates, Inc., Marblehead, Massachusetts. A voltage of from 50-300 volts at 100 milliamps was applied to the nylon cloth. The initial voltage was measured and then the current shut ,off.The time required for the voltage to drop to half its initial value with no current applied was recorded as the half-life time. The shorter the time, the faster the charge dissipated from the cloth.
  • the quaternary utilized was dicoco dimethyl ammonium chloride and the original silica sol was 1034-A.
  • Example III-C Utilizing the procedure of Example III-A, additional tests were made with different silica sols at a 1% solid silica level. Table II shows the results of the tests.
  • the quaternary dicoco dimethyl ammonium chloride and the original silica sol was 1034-A.
