Abstract
ABSTRACT
Economically produced of mouldings, more particularly elements for shaping façades. There is provided a base, preferably made of a synthetic foam material, having a protective skin consisting of a coating of flock which is then impregnated with a liquid synthetic resin. Such moulded bodies are inexpensive and are sufficiently strong and stable for outside use.

Description
~3~
The inven-tion relates to a moulded body, more particularly to an element for shaping facades, whether exterior or interior, especially in the form of a profile or relief piece, includin~ a base made S of a light material and a protective skin covering at least part of the outer surface of the base and containing a cured synthetic resin.
A moulded body of this kind is known from German Utility Model 86 07 314.1. This moulded body consists of a base and a protective skin, both made of the same basic material, namely a synthetic resin light mortar containing ylass or mineral fibres. For the purpose of saving weight, small synthetic resin spheres are mixed with the basic material of the base. If these sphéres are to be integrated satisfactorily, care must be taken to ensure that they are adhesive.
The known moulded body is relatively costly to produce and there are relatively narrow limits to the choice of materials for the base and the protective skin and to the con~iguration and dimensional stabili-ty of the body itself.
In addition, German Utility Model 19 48 908 discloses a hollow moulded body made of a thermo-plastic material, to wit polystyrene.
It is an object of the invention to providea moulded body of the type in question which has a resistant, sharply defined protective skin which is easy to produce and apply and which ensures reliable adhesion between the protective skin and the base, even in the case of complicated parts.
According to the invention, this object may be achieved if the protective skin consists of flock applied electrostatically and by providing a cured synthetic resin to hold the flock in place.
~q -, ~3~??~i ~40~2 Electros-tatic flocking makes it possible to produce profile or relief pieces with sharp contours.
The protective skin on the one hand contributes to increasing the strength of the moulded body but, on the other hand, it is not thick enough to raise problems in processing on site. For instance, profiles produced in accordance with the invention can be cut to length without the slightest trouble and by selecting a sultably dyed flock material, it is possible to produce a sandstone imitation at low cost.
The invention is explained in greater detail hereinafter in conjunction with the embodiment illustrated in the drawing attached hereto, wherein:
Fig. l is a cross-section view of the base of a moulded body;
Fig. 2 is another cross-section view showing the electrostatic flocking of the basic material forming protective skin;
Fig. 3 is yet another cross-section view showing the impregnation of the layer of flock with a liquid synthetic resin; and Fig. 4 is a cross-section view showing a finished moulded body~
In these fig~lres, l indicates the base of a moulded body of an element for shaping facades which is preferably made of hard polystyrene foam, i.e. a material noted for its extraordinarily low price.
However it would also be conceivable to use hard polyurethane foam, aerated concrete, breeze concrete, or polymer concrete and wood or metal as the material for the base.
As shown in Fig. 2, a covering layer 2 of flock is applied to base 1 from a container 3 which~
in prac-tice, is arranged above a conveyor belt 4 - :
6~
passing through a flocking station. ~fter the flocking operation, covering layer 2 is impregnated with a curable, liquid, synthetic resin. This ma~ be done manually, but is preferably done with a spray gun 5. If base 1 is made of hard polystyrene foam, the material of choice for impregnating the covering layer is an epoxy resin. On the one hand it imparts the necessary strength to incipient protective skin 6; on the other hand it lends itself to colouring the façade shaping element.
Immediately af-ter the application of the liquid synthetic resin, the protective skin 6 may be coated with sand, gypsum, cement or plastic powder.
Fig. 4 shows a finished façade shaping element carrying a coating 7 in the form of a layer of sand on its outer surface.
The façade shaping element is fixed to the wall in a manner known per se.
In practice, the thickness of protective skin 6 amounts to between 0.5 and 3 mm.
Depending upon the material from which the base is made instead of an epoxy resin, polyester, acrylic or polyurethane resins may also be used for impregnating the protective skin.
It is not absolutely essential for the hase to be flocked directly. It is also possible to use a separate protective skin carrier made of a thermoplastic material. This carrier, in the form of a deep drawn sleeve, comes to rest between base 1 and covering layer 2 in the finished product. On the other hand, it is also possible to build up the protective skin out of a plurality of consecutive -and possibly differen-t - curable synthetic resins, the addition layers being applied either directly, or after repeated electrostatic flocking, to the ...,. , ~.3~6~
previously applied layer. Moulded bodies of the type described may be produced extremely efficiently at low cost. A coating of gypsum, cement or plastic powder, applied electrostatically to the protective skin, not only increases resistance to wear but also improves brush-painting and paint adhesion. A
coating of gypsum or cement produces an increase in hardness by reaction with water vapour or mist.
After it has been applied, a coating of plastic powder is preferably heated again. In any case, care must be taken to provide an adhesive bridge between the coating and the protective skin. This can be obtained from the synthetic resin before it has solidified or, after it has cured, from an addition-ally applied adhesive. The amount of materialrequired for the base, and the weight of the latter may be very substantially reduced by using a hollow base.
