Description

POLYSTYRENE ELEMENT WITH IMPROVED MECHANICAL
RESISTANCE, METHOD FOR PRODUCING IT AND USE
THEREOF
DESCRIPTION
The present invention relates to polystyrene elements having improved mechanical resistance, methods for producing these, and use thereof.
Polystyrene is a material that is commonly used in the construction industry for its mechanic, sound absorbing and heat insulating properties. It can be moulded into any desired shape and, upon cooling, will largely retain its solid structure while providing certain elasticity. In order to increase the mechanical resistance of the polystyrene element, prior art uses a thermo-retractable film to cover at least one portion of at least one surface of the clement. Such polystyrene elements arc typically produced in a two-step process: the polystyrene is moulded in a cast, the cast is opened, a thermo-retractable film is introduced, and the cast is scaled for a second time to affix the film to the polystyrene element.
While this prior art undoubtedly confers mechanical resistance to the polystyrene element, it has several drawbacks. Most importantly, the film exerts a force on the element, thereby deforming it. In order to counteract this force, the polystyrene element must either be of sufficient density or of sufficient thickness, thereby limiting the available production and configuration parameters. Furthermore, the film must be of a pre-determined thickness: a too thick film reduces the elasticity of the clement and can lead to mechanical destruction of the element, whereas a too thin film can rupture. This also means that the characteristics of the polystyrene element and those of the film cannot be varied independently.
The force exerted by the film in the prior art also entails problems in terms of the function of the element. In the case where the element is to have a flat surface, deformation due to the force of the film is a significant obstacle. Where the element is used in construction for retaining tubes, particularly hot-water tubes in under-floor heating, deformation can cause displacement and bending of these and subsequent retention of fluid.
The use of a film also reduces the number of possible element configurations as the film cannot reach all the recesses of the polystyrene element. Even where the element is of a simple design, the film cannot reach all the crevices, thereby possibly causing rupture of the film where it is not flush with the element. Moreover, being a solid not made of polystyrene, the film can peel off from the polystyrene clement.
The technical task proposed by the present invention is therefore that of providing a method for producing a polystyrene element with improved mechanical resistance, a polystyrene element and use thereof, which overcome the noted technical drawbacks of the prior art.
In the scope of this technical task, one object of the invention is that of providing a polystyrene element with improved mechanical resistance while retaining elasticity.
Another object of the invention is that of enabling use of a large range of polystyrene element thicknesses, densities, and configurations.
A last but not least object of the invention is that of providing a polystyrene element with improved mechanical resistance with at least one flat surface, and thereby allowing use of the polystyrene element in construction.
The technical task, as well as these and other objects, are achieved according to the present invention by providing a method for increasing the mechanical resistance of a polystyrene element characterised in that it comprises a step of covering at least one portion of at least one surface of said polystyrene element with a water-based paint.
The present invention relates also a method for production of a polystyrene element with increased mechanical resistance, charactcrised in that it comprises a first step of moulding said polystyrene element into its fmal shape, a second step of natural or forced cooling and drying said moulded polystyrene element and a third step of applying a water-based paint on said moulded polystyrene element without using air as a medium for applying said water-based paint to said moulded polystyrene element.
Thus, whereas the use of a film requires a two-step moulding process, the use of a paint only requires one moulding step.
The present invention also relates to a polystyrene element characterised in that it has at least one portion of at least one of its surfaces covered by at least one layer of water-based paint suitable for at least improving mechanical resistance.
The water-based paint improves mechanical resistance to the element and helps to prevent the element from crumbling, while retaining elasticity. By not exerting deformational stress on the polystyrene element, it enables use of a much larger range of polystyrene thicknesses and densities.
Furthermore, there is no pre-determined paint thickness and the polystyrene and paint properties can be varied independently.
The polystyrene element can be of a low density type and preferably its density and the thickness of the paint deposited on it vary substantially inversely proportionally to each other.
Moreover the thickness of the layer of paint deposited is set directly proportional to the mechanical resistance to be conferred.
The water-based paint has chemical physical properties suitable for creating an interface layer constituted by said paint penetrated into said polystyrene element. This allows prevention of paint detachment from the surface of the polystyrene element, so the paint does not peel off from the polystyrene element.
The lack of deformation enables the element to have at least one flat surface. The paint also allows for a much larger range of polystyrene clement configurations as it can reach crevices and recessed that a film cannot reach.
The polystyrene clement can be in the form of a panel with at least one flat surface. A second flat surface enables the element to be used for decorative purposes, such as for covering walls. This second flat surface may be decorated, the decoration being either associated with the surface or impressed directly on it.
In one embodiment of the invention, a gas, particularly air, is not used as a medium for the application of the paint. Air-less application helps to prevent displacement of the relatively light-weight polystyrene element during paint application.
Other characteristics of the present invention are moreover defined in the subsequent claims.
Further characteristics and advantages of the present invention will be more evident from the description of a preferred, but not exclusive, embodiment of the polystyrene element with improved mechanical resistance according to the finding, illustrated in the attached non-limiting drawings, wherein: Figure 1 shows a perspective view of a polystyrene element having one surface covered with a water-based paint and having moulded protrusions in accordance with one embodiment of the invention, as well as the orientation of a hot-water tube in accordance with another embodiment of the invention; Figure 2 shows a perspective view of a polystyrene element having one surface covered with a water-based paint and having a coupling means in accordance with one embodiment of the invention; Figure 3 shows a cross-section of a polystyrene element having one surface covered with a water-based paint.
Figure 4 shows a plane view of a polystyrene element according to a second embodiment of the present invention; Figures 5, 6 and 7 are cross sections of the polystyrene element of figure 4 sectioned along line 5-5, 6-6 and 7-7 respectively.
With reference to the above figures, a possible structure of protrusions (1) can be seen, wherein they are arranged in a lattice configuration on a flat polystyrene element (2), have preferably polygonal cross section (3), have a longitudinal axis (4) orthogonal to the flat surface (5) upon which they arc affixed, and are of octagonal (figure 1) or pentagonal (figure 4) shape (6) around the longitudinal axis (4). The water-based paint (7) covers the protrusions (1) and the flat surface (5) upon which they are affixed.
It must be noted that, after the water based paint is applied, protrusions (1) maintain sharp edges that help to effectively retain an element placed on the polystyrene element (2). This is possible because the layer of water based paint applied on the protrusions (1) does not exert any intensive mechanical stress on them. The use of a thermo-rctractablc film, on the other hand, as in prior art technology, would create mechanical stress so intensive as to deform the protrusions (1) and make their edges rounded, thereby rendering the retaining action of the protrusions (1) less effective.
Figure 1 and 4 also show possible orientations of a hot-water tube (9), the retention of which is one of the uses of the present invention. Tubes (9) of different diameter can be accommodated depending on whether their orientation is orthogonal or sloping relative to a side of the polystyrene element (2).
The polystyrene element (2) may form part of an under-floor heating system, the protrusions (1) retaining the hot-water tube in a horizontal orientation, preventing displacement and bending of the tube when cement in poured on top of the polystyrene element. This in turn maintains the path of the hot-water tube as well as preventing the formation of vertical u-bends and subsequent fluid retention.
In this case, in addition to protrusions (1), spacer elements (8) are provided on the flat surface (5) to displace tubes (9) away from the flat surface (5).
In this way, when the polystyrene element (2) is buried, the cement or a similar fluid can flow and even fill spaces underneath the tubes (9).
The polystyrene element may also comprise moulded coupling means of male/female type to modularly engage with a further polystyrene element.
In one embodiment of the invention, Figure 2 shows these coupling means (10) in the form of a groove (11) and a rim (12) of conjugated shape, running rectilinearly and adjacent to each other and to a rectilinear edge of the polystyrene element (2) as well as a second groove (13) and rim (14) of conjugated shape, running rectilinearly and adjacent to each other and to a second rectilinear edge of the polystyrene element. The coupling means are within the perimeter of the lateral view of the flat polystyrene clement. In particular, they extend along the projection of the bottom or top surface of the flat polystyrene element. In this way, when adjacent flat polystyrene elements arc coupled, the top and bottom of the engaged coupling means arc coplanar with the top and bottom surface, respectively, of the coupled flat polystyrene elements.
With the same reasoning as referred to for the protrusions (1), even the coupling means can maintain sharp edges, thereby enabling a more effective engagement between polystyrene elements (2).
Figure 3 shows a cross-section of one embodiment of the invention. It can be seen that, at the paint-polystyrene interface (15), the paint (7) is attached directly to the polystyrene element (2) and follows the shape of any protrusions (1).
Due to the method of the present invention for coating a polystyrene element with water-based paint, protrusions (1) positioned very closely to each other can be provided while assuring an optimal and uniform adherence of the layer of water-based paint on them. Use of low density polystyrene in conjunction with a high density of protrusions (1) (i.e. number of protrusions per surface unit of the flat surface (5)) optimizes the sound absorption of the polystyrene element (2).
In prior art technology, due to the difficulty for the thermo-retractable film to penetrate and fit into recesses in the polystyrene element (2), adjacent protrusions (1) have to be positioned with a very large minimum distance between one another, thus providing the polystyrene element with poor sound absorption qualities.
The following is a non-limiting example of the typology of the water-based paint used for coating at least one part of one surface of the present invention.

The drying time depends on temperature, relative humidity and ventilation.
The paint has an optimal covering power in terms of filling and colouring power, is soft on touch, highly elastic and greatly conforms to the topology of the polystyrene element upon which is applied.
A further possible use of the polystyrene element of the present invention is in civil building field, for making a mould for a cement straining to be shaped as a decorative element like a frame of projection for roof gutter, said polystyrene based mould being easily removable from the cement after the latter is hardened, due to low adhesion property conferred to the polystyrene mould by the paint applied on it.
The polystyrene element with improved mechanical resistance thus conceived is susceptible to numerous modifications and variations, all falling within the scope of the inventive concept; furthermore, all details may be substituted by technically equivalent elements.
In practice, any material type or size may be used, according to needs and the state of the art.
