DE2256696B2 - PLASTIC MEASURES FOR PLAY, EDUCATION AND TEACHING PURPOSES - Google Patents

Description

The invention relates to a plastic mass for play, teaching and teaching purposes or the like. Made from Fillers, binders, plasticizers and dyes. With the main patent is to I.a. suggested that the mass for the production of colored and color-releasing images in water Contains emulsifiable dyes and a hydrophilic plasticizer. This mass can be modeled and can change their color by touching them when wet an ink receiving agent such as a sheet of paper or fabric. By using a hydrophilic plasticizer, the mass is water-absorbing.

With the help of such a mass, completely new areas of application for a playing child, a Artists, etc. developed. If it is moist, this mass can first be used to make molds, Figures and the like can be used. It is also able to absorb water and can use it give off paint when wet. One can proceed in such a way that masses of different colors are deformed and a flat cake or a similar structure is created, the flat surface of which is tius composed of masses of different coloration. If you moisten this flatbread or the one towards it means and if you put this means, e.g. a piece of paper or a piece of textile, on the flatbread, like this the image created with the flatbread is on the paper, the fabric or the like. transfer. So you can make a larger number of prints. Once a flatbread has been formed, it can be put aside and used at will can be kept for a long time, although it dries out and becomes very hard. But he can also broken down into its individual masses of a certain color and these can be used to form new molded parts or Flatbreads can be used again. The mass can be diluted with water. It can therefore be used after moistening Painting is used by removing the damp part of the mass with a brush or finger, for example and applies to the surface to be painted. With that, the playing child, the artist, the artistic active laypeople etc. give new, interesting and versatile design options η.

The object of the invention is a plastic, modellierbarc mass according to the teachings of the Haup'patents n in their plastic properties \

to enhance.

To solve this problem, the inventor *: * ·. '. such a large proportion of the hydrophilic plastic fixation mitreis suggested that the mass should be plastic without VV; remains kneadable. From this ctl'ü- a relief in the use of animal effort. J Thus, for their deformation and modeling, an addition of water is not necessary: At the same time, lL achieved with the advantage that during the Kn -. ^ :;

ίο or modeling no or only very little ^ ¥: -yr .. is given. Some color release can depend on the moisture content of the mass and also correspond to: ·. the moisture of the Firce processing the mass: enter. Such a mass does not dry out, i.e. becomes completely hard, but always retains its plastic properties. For the purposes of color transfer or painting, moisture is added to it or, as explained, the object to be printed is moistened.

The proportion of the hydrophilic plasticizer to the other constituents of the mass depends on the recipe used, in particular the type un j the amount of filler used. More details can be found in the example given below len. According to a preferred proposal of the invention a liquid plasticizer such as granine or polyglycol ether is used.

The invention according to the main patent has in Proven principle, as it allows the explained possibilities of color transfer and thus the creation of color prints as well as painting with this mass. Wed; of the present invention, measures of this property are now perfected in the manner illustrated and improved.

Further details and embodiments of the proposed masses are given below:

The plasticizer can be, for example: polyethylene glycol. Fatty acids of the alkali and alkaline earth metals such as sodium stearate, potassium soap and calcium oleate. Dextrin, glycerine and methyl cellulose can also be used as plasticizers will. According to a preferred embodiment of the invention, as explained, a liquid plasticizer is used used such as glycerine or polyglycol ether. This not only gives the desired plasticity, but also facilitates the absorption of moisture.

The filler can be hydrophobic (e.g. polyvinyl chloride). A hydrophilic filler is also possible. e.g. chalk, lime, bentonite, barium sulfate, clay and kaolin.

The hydrophilic, highly disperse pigment dyes used are, for example, mono- and diazo pigments of the naphthol series, their sodium or calcium salts, copper phthalocyanine and other organic pigments. A distributing agent mixed with these pigments can be a non-ionic product in a proportion of preferably 0.5 to 2% to the pigment mass. A mixture of alkyl and alkylaryl polyglycol ethers can serve as the dispersant.

An emulsifier can be added to the pigment. Mix such pigments particularly well with the inter alia preferred as filler

S ₅ used polyvinyl chloride. An aniline dye can also be provided as the dye. The addition of an emulsifier with a hydrophilic group is particularly useful for diluting

Mass with the addition of moisture, preferably waster. The following emulsifiers can be used: fatty acid amides. Polysaccharides, Turkish red oil. Monofemic acid ester Alkyl polyglycol ethers etc. In addition, the emulsifier supports plasticization.

To the examples given below. as preferred embodiments of the invention are to be seen, it is also pointed out that in order to achieve good plasticity there is a ratio the filler to the plasticizer in the range from 2.5: 1 to 7; 1 turned out to be particularly favorable Has. In this context it should be noted that some plasticizers, such as Sodium oleate or dextrin, also partly filler Have a function and that dextrin is also effective as a binding agent.

As indicated in the previous examples, in addition to the means for inducing A binding agent can also be added to the desired plasticity as a fixing agent. These binders, e.g. B. in example 1 the synthetic resin, serve to fix the released color with the carrier, whereby the fixation takes place through the action of heat.
