NEW WRINKLE, INC., DAYTON, OHIO, UNITED STATES OF AMERICA.

Lacquer paint, which on drying forms a wrinkled surface coating, and sat father its production.

Originator: W. A. Waldie.

Priority was given on May 3, 1939 (United States of America).

The present invention relates to such paints with the property of forming, on drying, a wrinkled coating which, to the exclusion of blasting oils, contains an oil-soluble synthetic resin, crude Chinese trawl oil, boiled linseed oil, a metallic desiccant and a putty agent. The invention is primarily intended to provide a lacquer paint of the type indicated, which after drying leaves a coating with such a finely wrinkled surface texture that the wrinkling is practically invisible to the naked eye. A lacquer paint produced according to the invention with this property can be characterized mainly in that in addition to the above-mentioned constituents it contains 2-5 percent of a desiccant containing vegetable fatty acids derived from vegetable drying oils dissolved in solvents, and a forged paste, containing a color pigment and asbestos .

The invention also has for its object a method of producing a lacquer paint of the specified kind, which is mainly characterized by mixing one quarter to three quarters of the amount of an oil-soluble synthetic resin which is intended to be inhaled, with the entire intended amount. Chinese trawl oil, heats the mixture to a temperature of 235-288 ° C, then adds a metallic desiccant, boiled linseed oil and the residue of the resin, the resin being dissolved in the mixture, after the addition of the residue of the resin cools the mixture rapidly, darpa adds diluent in such In order to obtain the desired consistency, a desiccant containing solvents dissolves free fatty acids from drying oils, and finally a paste containing color pigments and asbestos.

Below is an example of the composition of a completely free varnish component from blasted oils, which can be used in the production of a paint dye drying during wrinkle formation according to the invention: Varnish «A».

Modified phenaldehyde resin * (amberol resin „or becacacit resin) 100 kg Lead acetate or linoleate 5-9» RA Chinese trawl oil 125-208 1 Thickened linseed oil a 16,7-42 »Naphtha, as a solvent 75 –84» Toluene 150-208 » In the part of the varnish recipe given above, of course, all kinds of resins can be used in the place of the names. Suitable resins were kauri resin, dusting resin, congo resin, coumar resin, pontianal resin, manila resin, zanzibar resin, elemi resin, mastic resin, copal resin, sandarach resin and the like. In addition, other phenolic formaldehyde resins of the rosin, fossil resin and ester resin types can be used, which are readily homogeneously miscible with the oil carrier. Oil glyphate resins or mixtures of the abovementioned resins can be used.

Likewise, other wrinkle oils, such as e.g. Crude oil, poyula oil and essential oils, are used instead of crude Chinese trawl oil. The thickened linseed oil used is reflected in the quality that is commercially available under the name «varnish linseed oil». This product consists of linseed oil a, which is subjected to heat treatment between 303 and 316 ° C, until a desired degree of viscosity is obtained.

A particularly suitable method for producing varnish »A» consists in heating the whole amount of the Chinese trawl oil and about 1/4 --- "A of the resin together in a vessel to a temperature of about 282 ° C. Then the metallic is added. When the resin is dissolved, the varnish component can be cooled and diluted with the solvent, or it can be heated for a longer time and to obtain a higher viscosity, the dilution can occur. that by rapid cooling of the varnish component after the second batch of resin has been dissolved, a clear to wrinkled coating asysed varnish can be produced, which exhibits improved properties saval in question of being able to be sprayed in finely divided form as in the case of wrinkling. varnish »A» thus consists in a rapid cooling of the heat-treated homogeneous mass' at the end of the heat treatment. access to any suitable salt, for example by means of cold water or other coolant. By this method a product drying during wrinkling is obtained, which can be pitted in finely divided form and which is comparable to that produced during blowing in blasted oils. The product used as a surface coating is also durable and can be stored. The heat treatment of the varnish can be set to a temperature range between 232 and 288 ° C, but the heating is usually carried out at a temperature which is above 260 ° C.

By keeping the percentage of solids in the mixture equal and heating the product for different hanging times, the viscosity of the varnish can be regulated. The longer the varnish is heated, the better its viscosity, and the shorter the heating time, the lower the viscosity. This also applies to the amount of added solvent or diluent in these cases.

To the above-mentioned varnish "A" was added according to the invention about 2-5 of a liquid desiccant, containing fatty acids derived from drying oils dissolved in solvents. The following desiccant mixture was particularly satisfactory: liquid desiccant «A».

Cobalt linoleate, in solid form 12-16 kg Fatty acids derived from Chinese trawl oil of 810 »Toluene, xylene, petroleum naphtha with a boiling point of about 95-115 ° C or coal star solvent with a boiling point of about 115-175 ° C 671 Other examples of liquid desiccants, such as can anyandas, aro the following: Roll-shaped desiccant «B».

Lead linoleum 5-10 kg Cobalt acetate 9-6;,) Linseed oil fatty acids 2-5 »Fatty acids derived from Chinese tea oil 4-6.». Toluene, xylene, petroleum navel at a boiling point of approximately 95-115 ° C or a coal star solvent with a boiling point of approximately 115-175 ° C 50-67 1 Liquid desiccant «C».

Lead linoleate 4-8 kg Manganese borate 2-5 »Cobalt acetate 1-3» Fatty acids derived from drying oils (Chinese trace oil, linseed oil, etc.) 5-8 Toluene, xylene, petroleum naphtha with a boiling point of approximately 95-115 ° C or other coal-star solvent with a boiling point of 1750 C 50-71 For the production of a mixture which gives a wrinkled sample with the desired texture, the varnish "A" can be applied with a relatively low or high viscosity, determined according to Gardner-Holdt's method for examining varnish. In general, the higher the viscosity of the varnish> A> liar, the coarser the texture of the wrinkled surface coating.

Finally, in order to obtain a finer-textured sample which can be obtained by using a low-viscosity varnish, a desiccant is finally mixed according to the invention, comprising a varnish-like solution and fatty acids derived from dried oils. The following examples are typical.

Varnish »B».

Fatty acids derived from Chinese tra- oil 8-10 kg Toluene or xylene 8.3 1 Varnish «C».

Linseed oil fatty acids Fatty acids derived from Chinese trawl oil Toluene or xylene By adding a different percentage of varnish »B» or varnish »C», the texture or pattern of the 'rid drying caused the wrinkle. The larger the percentage of varnish »B» or «C», which was added to the varnish, the finer the texture of the obtained wrinkled surface coating.

For production on a paint-coated, varnish-drying coating or lacquer paint, paint can be rubbed into varnish n2b, which varnish can have either high or low viscosity, depending on the texture of the wrinkled surface coating. However, due to the volatility of the solvent used in the preparation of the varnish »A7, it is more appropriate to use a special demolition varnish for delta andanial. A typical example is the following: Varnish «D». l'lodified phenol aldehyde-resin (nmberol resin or becacacit- 1 resin) 00 kg Lead acetate or linoleate 5-9 »9-kg 3-8» 8,3 1 - —3 Rh Chinese trawl oil 125-167 1 Thickened linseed oil a 16, 7-42 I Toluene or xylene 67--100 I High boiling point petroleum naphtha (95-113 ° C) 299-418 I Varnish »D» is produced in the same way as varnish »A», but in some cases the heat treatment is continued, until a material with a high viscosity is obtained. This varnish is then mixed with commonly used paints, so that a paste of the desired color is obtained, and then it is passed through a paint grinder, so that the dye is completely distributed in the varnish bar. As an example of a colored paste, the following white pasta must be mentioned: White pasta 1.

Titanium oxide 8-10 kg Varnish »D» 8,3 1 A white wrinkling lacquer paint, removed during the use of the above paste, may have the following composition: White wrinkling lacquer paint.

Paste 1 2-3 kg Clear wrinkle varnish »A» 8,3 1 If the varnish »A» has good viscosity, the texture becomes coarser than that obtained when using a varnish with low viscosity, as explained above. In order to obtain lacquer paints, intended for the production of wrinkled coatings, to obtain finer-textured samples, an inert paste of the following typical composition was added: Inert paste 2.

Asbestos 810 kg Varnish »D» 8,3 1 Instead of asbestos givetyis other joke coloring fillers can be used, for example silicic acid, silex, sludge chalk, surfex (CaCO8), kaolin, etc. Some of these have much better effect On others and Concerns are more or less effective in developing the desired wrinkled finish of the dried lacquer coating.

After the colored pastes 1 and 2 have been prepared, alternating ingredients indifferent paste 2 are added to the lacquer color in order to obtain different textures of the wrinkled surface coating. However, there is a small amount of indifferent paste that can be mixed in before the skin becomes completely smooth during drying. The amount depends on the particular inert filler used in the preparation of the paste. After a sufficient amount of paste has been mixed into the lacquer paint, additives are added to the fatty acids derived from varnishing oils by varnish "B" or "C" in order to vary the texture pattern of the wrinkled surface coating. On this salt a wrinkled surface coating can be obtained with a texture sample, which Or said nicely, that it is practically Invisible to the naked eye.

In providing the improved wrinkled surface coating of the present invention, molds coated with the coating composition can be caused to have wrinkled surface conditions by allowing the coating to dry at relatively low or high temperature. For metallic and similar surfaces, a temperature of 60-246 ° C can be used. Yid on wood, paper and similar materials for coatings, a slightly lower temperature can be used, for example 52-66 ° C. When drying the coating at elevated temperature generally obtained a stronger wrinkle and a harder final condition. When you want to obtain a highly elastic membrane, you can add small amounts of joke drying or semi-drying oils, e.g. castor oil, cii soybean oil or similar materials. Emollient topics, such as e.g. dibutyl phthalate or dicresyl phosphate, can also be used.

As will be readily appreciated, the invention includes all such modifications which fall within the scope of the patent claims and the inventive concept.
