Description

(54) LAMINATED SHEET-TYPE WALL COVERING OR CEILING COVERING (71) We, IMPERIAL CHEMICAL INDUSTRIES LIMITED, Imperial Chemical House, Millbank, London SW1P 3JF, a British Company, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a sheet-type wail- covering or ceiling covering.
According to the present invention we provide a wall- or ceiling-covering comprising a laminate of a sheet of foamed aliphatic thermoplastic polymeric material and a paper sheet containing from 0 to 90% by dry weight of cellulosic fibres and at least 10% by dry weight of discontinuous fibres of a synthetic polymeric material.
In the wallcovering of the invention the foamed sheet provides, what is known in the art as, the working surface of the wallcovering and the paper sheet provides, what is known in the art as, the decorative surface of the wallcovering.
Such a wallcovering has a number of advantages over conventional wallcoverings. It is dry-strippable from the wall; it does not require to be soaked in paste and so can be attached to the wall merely by applying paste to the wall and it is sufficiently light to allow it to be hung direct from the roll. Furthermore the fibre-containing paper sheet exhibits improved toughness and, if embossed, improved emboss retention compared with conventional wallpaper bases.
The aliphatic thermoplastic polymeric material is one derived by polymerisation (which includes copolymerisation) of an ethylenically unsaturated monomer. Very often the monomer is an ethylenically unsaturated hydrocarbon e.g. olefine but it can, for instance, be a nitrile, such as acrylonitrile; vinyl or vinylidene chloride, vinyl acetate, or an acrylate, such as ethyl acrylate or methyl methacrylate.
When the monomer is a hydrocarbon this can, for instance, be ethylene, propylene or a butylene, for instance the polymer can be polyethylene (low density or high density material) or polypropylene. Moverover a copolymer can be employed such as a copolymer of a hydrocarbon monomer (e.g. ethylene) with another monomer, such as those given above. Thus the foamed resin can be an ethylene - vinyl acetate copolymer.
In preference, however, the aliphatic thermoplastic resin is a foamed low density polyolefine of bulk density from 0.05 to 0.5 g/cc having a permeability to air as measured by BS 2925 of from 0.0005 to 0.1 ml/cm2 sec. cm.head, a permeability to water vapour as measured by BS 3177 of from 500 to 10,000 g/m2 day mil and a permeability to water of from 0.5 to 100 ml.1m2 min. cm.head. Such a resin and a process for producing the resin is described in the specification of our British Patent 1,220,053.
The fibre-containing paper sheet may be made by a conventional paper-making technique from a mixture comprising 0 to 90% by dry weight of a cellulose pulp and at least 10% by dry weight of discontinuous fibres of a synthetic polymeric material.
The cellulose pulp used may be either a chemical, semi-chemical or mechanical pulp.
It is preferred, however, that the cellulose pulp is a chemical pulp comprising a mixture of hardwood pulp and softwood pulp.
It has been found that mixtures containing 30 to 90% by dry weight of chemical pulp and 10 to 70% by dry weight of discontinuous fibres of a synthetic polymeric material are particularly suitable for carrying out the invention.
Discontinuous fibres of a synthetic polymeric material are understood to mean fibrous structures of a synthetic polymeric material comprising very thin filaments of a micron order thickness which, in the paper sheet form a three-dimensional network. In preference the fibres have a length in the range between 0.5 mm and 5.0 mm.
The fibres may be of a synthetic polymeric material chosen from polyolefines, polyamides, polyesters, polyurethanes, polycarbonates, vinyl and acrylic resins. We prefer however to use fibres of a polymer of an alpha-olefne comprising 2 to 6 carbon atoms. In particular we find that excellent results are achieved with fibres of polyethylene.
The fibres may be produced by any suitable method. However the method of producing the paper is quite independent of the method used to manufacture the fibres with the result that all fibres of a synthetic polymeric material corresponding to the above mentioned criteria may be suitable, regardless of their method of production.
The composition used to produce the paper sheet may also contain other usual additives like binders, fillers such as talc or kaolin and pigments.
When making the sheet, it is preferable to incorporate the cellulose pulp in a suspension of the discontinuous fibres and then to subject the mixture to a refining and possibly pulp dispersion process in any equipment which can ensure intimate mixing of the components.
Preferably a wide angle cone refiner or a perforated or toothed disc disperser is used.
Finally the sheet is formed by conventional papermaking methods.
The foamed polymeric sheet and the fibrecontaining paper sheet may be laminated together by any suitable method. Conveniently a suitable adhesive is applied to one or both plies by a conventional spreading method for example air knife coating, knife over blanket, knife over roller, reverse roll coater and lamination achieved by passing the superimposed plies through the nip between two light pressure rollers. The adhesive is subsequently dried by passing the laminate through an oven.
The fibre-containing paper sheet, providing the decorative surface of the wallcovering, will be decorated with a suitable print and or emboss which may be applied to the paper sheet before or after it has been laminated to the foamed sheet. Desirably, however, when a deep embossed design is required the fibrecontaining paper or laminate, as the case may be, is heated to a temperature at least equal to but more preferably above the plasticity temperature of the fibres in the paper sheet before it is embossed.
The paper sheet may be heated by passing it through an oven whence the sheet can be embossed by a cold embossing roll. Alternatively and more desirably the cold sheet is embossed using a hot embossing roll at the appropriate temperature.
The invention will now be described with reference to the following Example: EXAMPLE A wallcovering according to the invention was made as follows: A paper sheet having a weight of 60 gsm and containing 50% by dry weight of cellulosic fibres and 50% by dry weight of polyethylene fibres having a thickness in the range 0.1 to 100 microns and a fibre length in the range 0.8 mm to 1.4 mm was provided with a continuous coating of an aqueous adhesive based on polyvinyl acetate and polyvinyl alcohol by an air-knife technique.
On the adhesive coated paper sheet was superimposed a sheet of foamed polyethylene (as sold by Imperial Chemical Industries Limited under the Registered Trade Mark 'Alkalite') having a thickness in the range 480 to 610 mm.
Lamination was achieved by passing the lay-up through the nip between two light pressure rollers and the laminate was passed through an oven maintained at a temperature of between 100 C and 1200C.
A two colour decorative print was applied to the decorative surface of the laminate by a gravure technique. When the print was dry, the printed surface of the laminate was embossed with a deep design by a hot embossing roller maintained at a temperature of 110 C, which was sufficiently high to render the polyethylene fibres plastic.
The product so formed was then rolled up in the manner of a conventional wallcovering.
A hanging trial was then carried out. A wall having a clean surface was pasted with an adhesive sold by Polycell Holdings Limited under the Registered Trade Mark 'Polymura' using a roller. A roll of the laminate was unrolled and the working surface of the laminate was offered up to the wall, smoothed into place and cut neatly at the top and bottom of the wall. This was repeated until the wall was covered by the laminate.
An inspection of the decorated wall showed that the deep embossed design in the laminate had been retained while the laminate was being hung. Furthermore mechanical tests established that the decorative surface of the laminate had a high scuff resistance and abrasion resistance.
WHAT WE CLAIM IS: 1. A wall- or ceiling- covering comprising a laminate of a sheet of foamed aliphatic themo- plastic polymeric material and a paper sheet containing from 0 to 90% by dry weight of cellulosic fibres and at least 10% by dry weight of discontinuous fibres of a synthetic polymesic material.
2. A wall- or ceiling- covering as claimed in Claim 1 in which the aliphatic thermoplastic polymeric material has been derived by the
