Description

United States Patent WOOD FINISHING COMPOSITION METHOD OF MAKING Frank H. Lyons, Memphis, Tenn., assignor to E. L. Bruce Company, Memphis, Tenn., a corporation of Delaware No Drawing. Application April 29, 1952, Serial No. 285,060
5 Claims. (Cl. 260-22) This invention relates to a wood finishing composition, more particularly a composition of the penetrating seal type adapted for the finishing of wood flooring and a method of making the finish.
The penetrating seal finish in accordance with this invention uniformly penetrates the surface andthe immediate sub-surface of hardwoods usable for flooring and thus provides a high degree of durability. Further, due to the uniformity of its penetration, it tends to prevent worn areas in flooring and obviates the necessity of removing any excess of the finish which has failed to penetrate.
Further, the finish in accordance with this invention provides a uniform finish-for wood having a pore structure varying from large to small in the same piece.
Further, it gives a uniform finish to a floor or unit of floor manufacture formed of different woods. This is of great utility, since it enables the flooring manufacturer and the fioor layer to use mixed floor wood, such as hackberry, elm, pecan, sycamore, ash, beech, persimmon, holly, locust and southern maple indiscriminately within the same unit. The customary hardwoods such as oak, maple, birch, and the like can be used either by themselves or also indiscriminately in the same unit.
The finish according to this invention lends itself to use in factory finishing where heat for curing or drying the finish is available, since it will dry tack-free in less than two minutes when exposed to conventionally used infrared lamp banks.
The finish when used in the field will air-dry in about four hours and may be combined with a filler-pigment so that on application of the finish the floor is at once filled, colored and finished.
The penetrating seal composition in accordance with this invention comprises a resin which is formed by reacting drying oil fatty acids, a pentaerythritol ester of rosin, dilinoleic acid, pentaerythritol and phthalic anhydride.
By way of more specific example, the drying oil fatty acids may be, for example, drying oil fatty acids free of both elaeostearic acid and licanic acid, such as linseed oil, soybean oil or perilla oil. A number of drying oil fatty acids containing elaeostearic acid and licanic acid, for example, oiticica oil or China-wood oil, may be substituted provided that the total of the elaeostearic acid and the licanic acid taken together does not exceed 40% by weight of the total oil fatty acids used.
The drying oil fatty acids referred to herein, including the specific examples, are the fatty acids in the normal commercial proportions derived from the specified oils.
The proportions can be modified but must not contain over 16% saturated fatty acids or over 40% oleic acid. Dilinoleic acid is readily available commercially.
The pentaerythritol ester of rosin will be the reaction product of pentaerythritol and rosin reacted to have an acid number of less than 20. This starting material is well known to the art and readily available commercially 2,734,879 Patented Feb. 14, 1956 ice as, for example, Pentalyn A, which is manufactured by the Hercules Powder Company.
More specifically, in the formation of the resin used in the penetrating seal finish in accordance with this invention, the drying oil fatty acids will be present in an amount from about 30 to by weight of the resin. As set forth above, the drying oil fatty acids may contain a total of from 0 to 40% elaeostearic acid and licanic acid. The pentaerythritol ester of rosin will be present in an amount of from about 18 to 35% by weight of the resin. The dilinoleic acid will be present in an amount of from about 5 to 15% by weight of the resin. The pentaerythritol will be present in an amount of from about 10 to 15 by weight of the resin. The ingredients in the amounts described will be batched together and a major portion reacted to completion to have an acid number of about 40 or less.
Phthalic anhydride will be used in an amount of from about 11 to 20% by weight of the resin and reacted with the above mentioned ingredients, the resinous product thus formed being reacted to substantial completion.
Preferably the actual acid number of the resin thus constituted will be from about 40 to 60, the products in this range having many advantages over the broader range products. In any event, the acid number must not be lower than 20 or higher than 85. The difference between the actual and calculated acid numbers is attributable to impurities found in commercially available products and to slight losses during manufacture and not to any substantial incompleteness of reaction, the reaction being preferably over 97% complete and, in all events, must be over 95% complete.
In order to avoid the confusion resulting from theoretical reactions, reactions with pure materials approaching the theoretical, and reactions with commercial materials, the calculated acid numbers used herein were determined by using the reacting purity of the commercial materials. By taking the reacting purity of pentaerythritol as 88%, we automatically compensate for the impurity of phthalic anhydride and the fatty acids. The following are the theoretical acid numbers used:
Drying oil fatty acids 200 Dilinoleic acid 200 Pentaerythritol ester of rosin l4 7 Phthalic anhydride 756 1 gram of pentaerythritol has the neutralizing effect of 1645 milligrams of KOH. Thus, taking the reaction purity of pentaerythritol as 88%, 1 gram pentaerythritol has the neutralizing effect of 1447.6 milligrams of KOH. When the resin is prepared by fusion the acid number may be slightly less than the calculated acid number due to a slight volatilization of the phthalic anhydride or to the fact that the pentaerythritol was slightly purer than assumed.
It is important to select the reaction times and temperatures to obtain completeness of reactions as indicated above. The times and temperatures will vary somewhat depending upon the selection of ingredients. A temperature range of 400 F. to 450 F. will be satisfactory. The reactiontime will be determined by close watching of the acid number or by azeotropic distillation and weighing the water, both means giving satisfactory indication of the completeness of reaction.
The drying oil fatty acids, the pentaerythritol ester of rosin, the dilinoleic acid and the pentaerythritol will be first reacted in, for example, a conventional jacketed reactor at a temperature of from about 400 to 450 F.
and the initial reaction carried to a completeness of; over 50%. A time of about one hour is required.
temperature raised to within about the range of 400 to 450 F. The reaction will go to the completion of 97' to 98% in from two to three hours.
. The resin product thus formerlis added to a solvent in a cooling tank in order to give the final product a viscosity of Al to A3 (Gardner scale). In order to achieve this "iscosity the product at. this stage will comprise from about 25 to 50% resin solids. Solvents conventionally used in forming. floor finishes may be used. Thus, for example, conventional floor finishing solvents such as aromatic petroleum solvents having a kauri butanol range of 50 to 80; mineral spirits or naphtha each having a kauri butanol number of about 37; coal tar solvents, such as benzene, toluene, xylene; methyl acetone, butyl Cellosolve and other solvents which are well known to the art as floor finishing solvents, may be used.
One or more driers will then be added to the preparation. Conventional cobalt driers and manganese driers are satisfactory. Mixed cobalt and manganese driers are satisfactory. Thus, for example, cobalt naphthenate, cobalt tallate, manganese naphthenate and manganese tallate, or mixtures thereof, are satisfactory. it is desirable to have calcium present in the drier.
By way of more specific example, the drier may be a combination drier having a cobalt content of .06 to 12% by weight, a manganese content of .15 to .3% by Weight and calcium .05 to .15% by weight of the resin.
Where it is desired, a filler such as, for example, silica, asbestine, gypsum, diatomaceous earth, kieselguhr, calcium carbonate and talc may be included in conventional amounts.
Further, pigment such as, for example, raw sienna, burnt umber, iron oxide, titanium dioxide, burnt sienna, lamp black, Prussian blue, precipitated lakes, zinc chromate and chrome yellow may be added.
There is given below a schematic representation of the resin product of this invention as used in the penetrating seal finish where linseed oil fatty acids are used. It will be understood that the schematic representation is of only one of the many isomeric forms which the product can take. In the schematic representation R equals rosin, LOFA equals linseed oil fatty acid, the references to the constituents of the product being made to the starting material and the crossing of lines indicating linking of the starting materials through condensation of hydroxyl and carboxyl groups. The phthalic acid is derived from the phthalic anhydride which is used as a starting material, the phthalic anhydride acting as a dehydrating agent forming phthalic acid and promoting overall reaction.
