Definitions

  • the invention relates to a profile made of polyvinyl chloride (PVC) for separating a room, in particular a swimming pool, the profile having a separate area, and a method for producing the profile, in particular a swimming pool cover.
  • PVC polyvinyl chloride
  • a roller shutter profile rod is known from the patent specification DE 41 01 727 C2, which is produced, among other things, from a transparent polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • BESTATIGUNGSKOPIE Roller shutter profile bars on another transparent plastic for example polymethyl methacrylate (PMMA), which is more stable against the ultraviolet radiation of sunlight than the polyvinyl chloride (PVC).
  • PMMA polymethyl methacrylate
  • PVC polyvinyl chloride
  • the transparent plastic is intended to protect the remaining body of the roller shutter profile rod, which is formed from normal PVC, against the ultraviolet radiation, so that the aging process of the PVC, in particular glazing of the PVC, is prevented or reduced.
  • the lower wall of the roller shutter profile bar has a blackened coating that interacts directly with the water in the swimming pool.
  • the blackened area should better absorb the heat radiation from the sun and dissipate it directly to the water surface.
  • the problem here is that the roller shutter profile rod, if it is not in direct contact with the cooling water surface, for example, heats up very strongly, so that the Vicat softening point of the PVC is reached and the roller shutter profile rod is thereby damaged.
  • the roller shutter profile bar with the ultraviolet ray absorbing plastic layer and the blackened polyvinyl chloride is manufactured using a triextrusion process.
  • a roller shutter is also known from DE 30 44 949 AI, the slats of which have a transparent, translucent upper side and a light-absorbing lower half which is in direct contact with the water surface.
  • the lower area of the lamella is tooth-shaped, which is to ensure that the solar radiation is more effectively absorbed from different angles of incidence.
  • the sawtooth profile also increases the surface area, which increases the light-absorbing surface. Overheating of the plastic is also critical here, since this often leads to irreparable destruction of the fins.
  • the invention has for its object to further develop such roller shutter profiles.
  • the invention is achieved by a profile made of polyvinyl chloride (PVC) for separating a room, in particular a swimming pool, wherein a material of acrylonitrile-butadiene-styrene copolymer (ABS) or a PVC mixed with the ABS is arranged in a region of the profile and ABS or PVC mixed with ABS has a higher Vicat softening point than conventional PVC.
  • PVC polyvinyl chloride
  • the profile in the area of the ABS or of the PVC enriched with ABS is significantly less sensitive to possible overheating. This is the case, for example, for a component that is frequently exposed to intense solar radiation. If the exposure time is too long, it often happens that the component made of conventional PVC is irreversibly deformed and thus destroyed. It has been shown that the ABS, in particular the PVC mixed with ABS, surprisingly retains the good mechanical properties of the conventional PVC, as a result of which, for example, the range of use of the PVC is also significantly expanded.
  • the ABS or the PVC mixed with ABS has a Vicat softening point of 90 ° C., preferably a Vicat softening point of more than 100 ° C. Since a temperature above 80 ° C can easily arise with a correspondingly long exposure time of heat energy, it is advantageous if the Vicat softening point of the ABS or the PVC mixed with ABS is above the heating temperature.
  • the profile gains increased protection against destruction or against deformation due to excessive temperatures.
  • This is of particular interest when, for example, the profile has no direct cooling through contact with the water in the swimming pool, so that temperatures of over 80 ° C can easily be reached in direct sunlight.
  • Commercial PVC on the other hand, often only has a Vicat softening point of approx. 83 ° C, which often causes a profile made from this PVC to become irreversibly deformed when it is overheated due to excessive sunlight and is therefore unusable.
  • the ABS containing PVC thus has significantly improved thermal properties, so that it is more resistant than a normal PVC. For example, this also increases the operational reliability of a profile which has a PVC mixed with ABS.
  • a PVC mixed with ABS which has a Vicat softening point of 103 ° C., was found to be particularly suitable.
  • ABS portion of the PVC mixed with ABS is more than 10% by weight, preferably more than 30% by weight.
  • an ABS content of more than 30% by weight means that the profile in this area is particularly weather-resistant and particularly scratch-resistant.
  • a preferred exemplary embodiment provides that the ABS or the PVC mixed with ABS is arranged on the underside of the profile.
  • a profile which is used for a swimming pool cover heats up particularly on its underside, so that it is particularly advantageous here if the ABS or the PVC mixed with ABS is attached to the underside. is ordered. Based on the experience gained, arranging the ABS or the PVC mixed with ABS on the top of the profile does not seem to make sense. If an application makes it necessary, it is advantageous if, for example, a PVC mixed with ABS is provided on the top.
  • the profile can still be produced using a conventional Triextusion process. It is advantageous if the ABS or the PVC mixed with ABS is colored dark, in particular black.
  • the underside of the profile is in direct contact with the water surface of a swimming pool, it makes sense to color this area. It is known that dark surfaces absorb more heat energy from the sun than light surfaces, so that such surfaces heat up more than, for example, a transparent surface or a white surface. The colored underside is exposed to a much higher temperature than the water in the pool, causing the water to heat up accordingly. In order to achieve optimal heating of the water basin, it is advantageous if the colored area is black. Black areas absorb heat energy particularly well, especially the heat energy from infrared radiation, which causes them to heat up particularly strongly. In the case of dark surfaces in particular, it is advantageous if they are made of ABS or if they have PVC mixed with ABS.
  • Top has a UV-stabilized PVC.
  • the UV-stabilized PVC protects the remaining PVC body much better against UV radiation, which, for example, can significantly increase the lifespan of a swimming pool cover. For example, glazing of the PVC is reduced.
  • PVC poly lyacryl
  • the upper side of the profile can also be provided with a UV-stabilizing PVC independently of an underside consisting or coated with ABS and also independently of an underside equipped with ABS mixed with ABS and vice versa.
  • the UV radiation stabilized PVC is arranged at a distance from the area comprising ABS. Especially when the PVC mixed with ABS is colored in a dark color, this PVC area heats up particularly strongly compared to the rest of the profile. In order to prevent damage to the UV-stabilized PVC due to thermal overheating, it is advantageous if the area of the profile comprising ABS is spaced apart, that is to say not in the immediate vicinity, of the UV-stabilized PVC.
  • the UV-stabilized PVC can also be arranged in the immediate vicinity of the PVC containing ABS.
  • an insulator is arranged between the UV-stabilized PVC and the area containing ABS.
  • the isolator can have air as a particularly advantageous construction.
  • the proportion of UV-stabilized PVC with respect to the upper side of the profile is more than 10% by weight, preferably more than 30% by weight. This ensures that the risk of the profile being destroyed by UV rays can be substantially reduced.
  • One embodiment provides, for example, that a plurality of profiles coupled to one another form a roller shutter, in particular a swimming pool cover.
  • a profile made of ABS or the new PVC material is particularly suitable for the use of a large-area cover, since the large areas to be covered are particularly strongly exposed to the sun's rays.
  • profiles of this type can be used wherever, on the one hand, a surface is to be protected against contamination or damage, and on the other hand, the thermal radiation of solar energy is to be used optimally.
  • the PVC material according to the invention in the field of industrial water heating by solar energy, since the material can also be exposed to an intense thermal load there.
  • the new PVC material is also suitable for use as a building material for greenhouses or the like.
  • the good mechanical properties of conventional PVC are necessary in many applications. Supplemented by an increased Vicat softening point, the area of application expands considerably.
  • the stated object is also achieved by means of a method for producing a profile, in particular a swimming pool cover, at least one further material, preferably the material acrylonitrile-butadiene-styrene copolymer (ABS), being added to a PVC, so that a special PVC is thereby obtained -Material with a high Vicat softening point.
  • ABS material enriched with PVC advantageously has the unrestricted mechanical properties of commercially available PVC, so that there are no restrictions in the previous areas of application.
  • PVC and ABS are used to produce a PVC profile with a high Vicat softening point.
  • the use of PVC and ABS materials is particularly advantageous because the combination of these two materials produces PVC with an unexpectedly high Vicat softening point.
  • the profile for producing a swimming pool cover by stringing together a large number of such profiles is particularly advantageous.
  • the cover of a swimming pool usually has a large surface, which is often exposed to intense sunlight, so that it is advantageous to use profiles as a cover, which are at least partially made of ABS or at least partially made of ABS-enriched PVC. Since the profiles of such a cover are exposed to a high mechanical load when moving apart or when moving together, it is advantageous if the profiles continue to have the good mechanical properties of a conventional PVC.
  • the combination of the upper and lower layers on a profile is particularly advantageous.
  • the figure shows a cross section through a profile.
  • the profile 1 produced by means of a tri-fusion process has a body 2 made of conventional PVC. On the underside of the body 2 there is a layer 3 with blackened and ABS-coated PVC.

  • the layer 5 of the body 2 is largely resistant to the destructive influence of UV rays, whereby the rest of the body 2, including the layer 3, is protected against the damaging effects of UV radiation.
  • the body 2 is permeable to infrared rays from sunlight, so that the thermal energy of the sun reaches the layer 3 in the form of infrared radiation, where the infrared radiation is then largely absorbed.
