Description

Protective coating. The subject of the invention is a polish-like or lacquer-like one Paint for furniture, floors or the like, also for building components and objects made of wood, metal, stone and the like can be used, they may now be used in rooms or outside.

As is well known to cause corrosion of the atmosphere or of the weather conditions exerts a damaging influence on Bautöle from metal, stone, and wood. D- 1 as well as on the usual protective coatings, whose adverse effects are to be eliminated by the protective coating according to the invention.

For this purpose, the protective coating according to the invention is given a Product obtained from your common commercial rosin is that one removes part of the volatile constituents by evaporation and which is such that when it liquefies and is applied to a surface does not crack if it hardens under considerable fluctuations in air temperatures.

Ordinary commercially available ones are used to manufacture the resin product Colophony placed in an open or closed container and at a heated to such a high temperature that some of the volatile constituents evaporate. Since the common, commercially available rosin is very different, ever. according to the type of distillation, your degree of distillation and the nature and the goodness of the trees from which it was taken, so the yield of the changes volatile constituents evaporated within fairly wide limits.

The evaporation temperature is not fixed once and for all, but rather changes according to the nature and composition of the ordinary commercial Colophoniums.

The evaporation temperature can be any temperature (with a certain variable maximum temperature) at which light resin oil from your commercially available Vaporized rosin. The lowest temperature at which light rosin oil is removed from the Resin evaporates is not always the same. It changes with the type rles used Colophoniums. The maximum also changes with the type of rosin used Temperature at which light resin oil without discoloration of the coagulated product can be vaporized.

The preferred evaporation temperature is the maximum temperature, at which light resin oil from a certain amount of the commercially available rosin evaporated without discoloration of the coagulated product. This temperature is. naturally different for different types of rosin and will initially found on a sample of the same, and found the temperature at which (read product is discolored.

Even if any temperature between the lowest and the highest temperature may be suitable for obtaining the desired product, the Maximum temperature preferred for economic reasons to prevent evaporation support financially.

In some cases, e.g. B. (read Pi oduct when making a clear varnish should be used, it is essential that no discoloration occurs, so that in this case the temperature is the maximum temperature for the treated Resin must not exceed. Should the product against it. for example in manufacturing If a colored varnish or paint is used, it will be reduced by a small amount Discoloration not unsuitable for this purpose.

The evaporation of the volatiles continues until all of the rosin oil is removed, and then continue doing this until the desired product is obtained is. The degree of evaporation after the resin oil has been driven off is also variable and regardless of the type or nature of the Coloplioniunis, e.g. B. from his Degree of hardness. The evaporation is stopped when the desired product is obtained is. The amount of heavy resin oil remaining in (no product changes depending on the type of rosin.

During the "earth evaporation" the degree of evaporation and the place at which all the resin oil is driven off, observed. Then from time to time a sample is taken and spread on a surface in a liquid state. Rips this sample does not if it is exposed to a temperature of about o '= C and solidifies, the evaporation is stopped as the desired product is obtained is. If the evaporation is continued for too long, the product will be decolorized and destroyed. In order to obtain the desired product, the evaporation takes place on a Interrupted point, which changes after all the resin oil has evaporated and before the defoliation and destruction takes place. This point is made through experimentation and samples found.

After the resin product is recovered, it is liquefied, namely by applying heat or by adding a solvent, e.g. B. one drying or non-drying oil or the like. The solvent can also can be used at the same time as heating.

The liquefied resin product can be applied to the components or be mixed in suitable proportions with ordinary colors, those hard Substances such as B. sand o. The like., Are mixed. You can also use the resin Mixing in colors without the hard substances or the hard substances without them Add colors.

For example, it becomes 50 parts by weight of the liquefied resin product and 50 parts by weight of ordinary paints are mixed, or 50 parts by weight are mixed liquid resin products finite 25 parts by weight of ordinary paints and 25 parts by weight hard substances: If a polish for furniture, floors, etc. is required, then the liquid resin mass mixed with suitable materials in a suitable ratio, such as B. Aniliilfarhstoffen, earth colors, stains and the like.

The liquid resin composition and the dyes can be in the following proportions mixed «earth: 95 parts by weight of liquid resin composition and 5 parts by weight of green Colour.

Claims (1)

PATENT CLAIM: Schtitzanstr I, consisting of a possibly finite dyes and hard powdery substances (such as sand) mixed resin mass, which is obtained from ordinary rosin in the manner (leave the more volatile Ground components including the light resin oil by evaporation @N and evaporation is continued to such an extent that after the light resin oil has been stripped off a residue remains, which solidifies at about 0 ° C and becomes liquid when spread on Condition on a surface does not tear.
