Abstract

The invention concerns an ecological lining for wallpaper, consisting of a composition of one or more vegetal resins.
Examples of the vegetal resins can be the resins MAGALEM 2650, MAGALEM 6005 and MAGACLEAR 687, to which can eventually be added some additives of natural origin, as the resins MAGAWET N and MAGACOLOR BIANCO S.

Description

  • The present invention concerns an ecological lining for wallpaper, particularly suited to replace the polyvinyl chloride used up-to-date.
  • According to known technique, wallpapers are prepared nowadays by hot spreading a layer of PVC on a paper sheet. The combined material thus obtained is then painted and newly hot embossed. As known, PVC is a toxic and cancerogenous substance. It is hence evident that such a dressing process, which involves several hot-working steps, causes considerable amounts of PVC, in the form of vapours, to penetrate into the ambient air, with possible damages for the health of the people doing the work or, in the best of assumptions, with very high fixed costs for the setting up and operation of plants and machinery allowing to efficiently remove the harmful substances from the working environment.
  • Furthermore, the good quality wallpapers normally last a very long time so that, in the long run, part of the PVC of the external layer tends to be released also in the environment where the wallpaper has been applied, with possible damages for the health of the customer. This damage is even more likely to occur in environments occupied by children, where the stresses are higher, since they tend to scratch the wallpaper and possibly inhale some flakes thereof. Moreover, at the end of their use, the wallpapers are eliminated, creating wastes with a given toxicity, even though they are not classified as special wastes.
  • On the other hand, in spite of there being a great variety of plastic materials which are atoxic, or anyhow less harmful than PVC, it has not been possible up to now to find a material apt to combine the washability with the resistance to scratches and to heat, as provided by PVC.
  • These and other drawbacks are brilliantly solved by the present invention, which concerns an ecological lining for wallpaper, characterized in that it consists of a composition of one or more vegetal resins.
  • Preferably, said composition comprises the commercial vegetal resins MAGALEM 2650, MAGALEM 6005, MAGACLEAR 687, available at Maga's Plast S.a.s., Via Marconi 16/A, 20024 Garbagnate Milanese (Milan), Italy. To such resins, one may eventually add one or more of the following commercial vegetal resins: MAGAVET N and MAGACOLOR BIANCO S, also available at Maga's Plast S.a.s..
  • A preferred composition comprises from 30% to 70% by weight of MAGALEM 2650, from 21% to 61% by weight of MAGALEM 6005, from 0% to 10% by weight of MAGAWET N, from 0% to 15% by weight of MAGACOLOR BIANCO S, and from 0,001% to 5% by weight of MAGACLEAR 687. Still preferred is a composition comprising from 40% to 60% by weight of MAGALEM 2650, from 31% to 51% by weight of MAGALEM 6005, from 0,001% to 5% by weight of MAGAWET N, from 5% to 10% by weight of MAGACOLOR BIANCO S, and from 0,1% to 2% by weight of MAGACLEAR 687.
  • Further advantages of the present invention will anyhow be more evident from the following detailed description thereof.
  • The present invention provides for the use of resins of vegetal origin to prepare wallpaper.
  • The support paper is lined with the mixture of resins, so as to acquire the properties of impermeabilization and resistance to scratches and heat, typical of such papers.
  • Particularly suitable resins are those marketed by Maga's Plast under the names of MAGALEM 2650, MAGALEM 6005 and MAGACLEAR 687, or having a similar composition. Additives can be added to such resins, also of natural origin, such as the resins marketed by Maga's Plast under the names of MAGAWET N and MAGACOLOR BIANCO S, or having a similar composition.
  • All these resins are latexes modified in an aqueous suspension.
  • Preferably, the mixture is prepared with a composition including the following ranges, where the percentages are percentages in weight on the whole composition:
    MAGALEM 2650 30-70%
    MAGALEM 6005 21-61%
    MAGAWET N 0-10%
    MAGACOLOR BIANCO S 0-15%
    MAGACLEAR 687 0,001- 5%
  • Particularly good results are obtained with a composition falling within the following ranges:
    MAGALEM 2650 40-60%
    MAGALEM 6005 31-51%
    MAGAWET N 0,001- 5%
    MAGACOLOR BIANCO S 5-10%
    MAGACLEAR 687 0,1- 2%
  • The ecological lining according to the present invention is applied with the common methods adopted in known technique. The vegetal resins allow to obtain an impermeabilization and a strength to scratches which is in no way inferior to those which can be obtained with the normal PVC linings. Also the final hot embossing treatment is carried out without creating any problems. It is hence positively deemed to have obtained a lining which provides all the advantages of PVC, without the need to contain halogens, phthalic plasticizers and heavy metals, so as to involve exceptional benefits as far as health and impact on the environment.
  • The two examples given hereunder allow to establish the validity of the composition according to the present invention, without however limiting its scope.
    • EXAMPLE 1
  • An ecological lining according to the present invention was prepared with the following composition (the values are percentages in weight):
    MAGALEM 2650 43,7
    MAGALEM 6005 45,0
    MAGAWET N 2,3
    MAGACOLOR BIANCO S 7,5
    MAGACLEAR 687 1,5
  • A perfectly spreadable liquid was obtained, which was subsequently hot applied onto a paper support and embossed. The comparison with a similar wallpaper lined in a conventional manner showed no defects.
    • EXAMPLE 2
  • An ecological lining according to the present invention was prepared with the following composition ratio:
    MAGALEM 2650 65,0
    MAGALEM 6005 31,5
    MAGACLEAR 687 3,5
  • A spreadable viscous liquid was obtained, which was hot applied onto a paper support and embossed. No appreciable defects were evidenced in comparison with a conventionally produced wallpaper.
    • EXAMPLE 3
  • An ecological lining according to the present invention was prepared with the following composition ratio:
    MAGALEM 2650 49,7
    MAGALEM 6005 40,6
    MAGAWET N 0,2
    MAGACOLOR BIANCO S 9,0
    MAGACLEAR 687 0,5
  • A spreadable liquid was obtained, which was hot applied onto a paper support and embossed. No appreciable defects were evidenced in comparison with a conventionally produced wallpaper.
