Definitions

  • the invention relates to a covering in the form of a tile or a mat containing ethylene-butylacrylate copolymer (EBA) as a binder.
  • EBA ethylene-butylacrylate copolymer
  • the covering according to the invention is particularly suitable for covering floors and walls.
  • PVC Polyvinyl chloride
  • UVC-based coverings have been considered to have e.g. physical properties superior to coverings containing no halogens, such as rubber and linoleum coverings, which were used widely previously.
  • halogen-containing materials such as PVC in coverings
  • PVC halogen-containing materials
  • EP 321760 is referred to.
  • EVA ethyl vinyl acetate copolymer
  • the object of the present invention was to provide a covering which contains no halogens, thus meeting the requirements of special fields and being environment-friendly.
  • the covering must not contain any substances hazardous to health that evaporate at normal ambient temperatures into the surrounding space, such as solvents and plasticisers.
  • the product should be thermoplastic so that it can be machined by known techniques, and it should be re ⁇ cyclable. It is also necessary that the product can be produced in the form of tiles or a mat that can be rolled up, and the appearance of the product should be easily variable. Moreover, the installation and removal (for recycling) should be easy.
  • the basic properties of the covering in use should corre ⁇ spond to those of known covering products. Such basic properties include not only different well-known mechanical properties such as resistance to depression (load), resistance to wear, and dimensional stability, but also cleansability.
  • the covering according to the present invention meets the basic criteria set forth above.
  • Products disclosed in the above-mentioned EP Patent Specifica ⁇ tion 321761 meet partly some of the criteria, being e.g halogen-free, thermoplastic and recyclable. How ⁇ ever, it has now been found out that the covering according to the present invention has significant advantages over the above-mentioned products.
  • the present invention relates to a covering which is in the form of a tile or a mat, has a wear- resistant surface, and is made of a mixture containing a binder, a filler and possibly additives.
  • the cover ⁇ ing is characterized in that the binder contains ethylene-butylacrylate copolymer (EBA).
  • the covering according to the invention is typically a semi-rigid tile or a flexible mat, and it may be homogenous or of sandwich-structure, of a single colour or patterned.
  • the proportion of EBA in the binder used is preferably 20 to 80% by weight.
  • Suitable EBA polymers are those having a butylacrylate content of 5 to 28%.
  • other binders may be used in addition to EBA, such as various propylene polymers and copolymers, e.g. random polypropylenes.
  • the total amount of binders in the covering is preferably 20 to 80% by weight based on the total weight of the covering.
  • the covering contains suitable inorganic or organic fillers and possibly additives.
  • Suitable fillers include chalk, kaolin, limestone or dolomite powder, various silicate mineral powders, quartz power or sand, and organic or inorganic fibres.
  • Typical fillers include antistatic agents, photostabilizers, antioxidants, and colorants.
  • the amount of the fillers and additives is preferably 20 to 80% by weight, of which the proportion of additives is generally no more than 5% by weight based on the total weight of the covering.
  • the covering according to the invention may be produced in a manner known per se by utilizing processes applied in the production of corresponding PVC-based products. For instance, the production of a floor tile containing mainly quartz sand (grain size 0.1 to 0.8 mm) as a filler and EBA and random poly ⁇ propylenes as a binder takes place by mixing the filler and binder components together in a dry-mixer type device and melting the mixture so obtained in an extruder. The molten mixture is passed into a two-roll mill from which it is fed to a calender for calender ⁇ ing into a tile blank of a desired thickness. Melting may also be carried out directly by the two-roll mill.
  • quartz sand grain size 0.1 to 0.8 mm
  • EBA and random poly ⁇ propylenes as a binder
  • the tile blank is fed as a continuous web into a so-called double-band press and compressed into a tile band which is cut into tiles of a desired size, e.g. 30 x 30 cm or 50 x 50 cm, or (b) the tile blank is cut into tiles of a suitable length, and the tiles are then cooled and pressed in a separate step in a multiple unit press, and the finished blanks so obtained are cut into tiles of a desired size.
  • a desired size e.g. 30 x 30 cm or 50 x 50 cm
  • the tiles may be patterned in the same way as PVC-based products by preparing grains of different colours and 1 to 15 mm in size of the same or partially modified material and mixing them cold with the hot material in the two-roll mill or squeezing them into the hot tile blank in the double-band or multiple-unit press.
  • the properties of the covering according to the invention are superior to those of a corresponding PVC-based product in sur ⁇ prisingly many respects: - It has been found that, with the same filler composition and the same binder/filler ratio, the covering according to the invention has a signific ⁇ antly greater stiffness in addition to other equally good properties, which is of vital importance in practical installation work and also affects the requirements concerning the underlying floor.
  • the covering according to the invention has a clearly better depression resistance, which is one of the most important properties for floor coverings.
  • the temperature range within which the covering according to the invention is usable is wider, i.e. the properties of the covering do not vary essentially as a function of temperature within the temperature range 0 to 50°C.
  • the binder contained in the covering according to the invention provides better cold creep properties, i.e. a higher resistance to long-term load.
  • the wear resistance of the covering according to the invention is clearly higher with the same filler/ binder volume ratio.
  • the covering according to the invention is about 20% lighter than the PVC-based product, which is signi ⁇ ficant for the handling, cost of transport and impact- sound damping properties.
  • the dirt-repelling and general cleansability prop ⁇ erties of the covering according to the invention are superior to those of PVC-based products.
  • the covering according to the invention does not contain any separate liquid plasticisers, no migration of plasticisers occurs to the surface of the covering nor do any external e.g. oil-soluble coloured or uncoloured substances penetrate from the surface of the covering deeper inside the covering as with PVC- based products.
  • the covering accord ⁇ ing to the invention differs to its advantage from similar PVC-based products.
  • the covering according to the invention also differs significantly and surprisingly to its advant- age from EVA-based coverings (see EP 321761) in that the temperature range within which the covering according to the invention is usable is wider, i.e. temperature changes affect the mechanical properties of the covering less than with EVA-based products.
  • the dirt-repelling and cleansability properties of EBA- based floor coverings are essentially better than those of corresponding EVA-based coverings, the surface of which is rather sticky due to the binder composition used.
  • the depression resistance and creep properties of the covering according to the invention are also superior to those of corresponding EVA-based products.
  • the vinyl acetate contained in EVA-based products has been clas ⁇ sified as a substance suspected of being carcinogenic.
  • the following examples are illustrative of the invention.
  • a covering was prepared by using the following ingredients and amounts:
  • Ethylene-butylacrylate copolymer 1 100.0 kg 25.8% by weight
  • Polypropylene 2 25.0 kg 6,5% by weight
  • NCPE 8019 manufacturer Neste Oy, acrylate content 17%, melt index 1.5 g/10 min
  • the ingredients were mixed at room temperature into a homogenous mixture.
  • the mixture was fed into a two-roll mill having a roll temperature of +210°C.
  • the temperature of the material increased to +195°C.
  • From the mill the hot material was passed in the form of a continuous band into a tandem calender having a roll temperature of +140°C.
  • the roll nip was adjusted so that the 70 cm wide band produced by the calender was 2.15 mm in thickness.
  • Crushed grains of a desired colour prepared in advance of the same material were sprinkled on the band for patterning.
  • the grains were squeezed into the band by a pair of steel rolls.
  • the band was then cut into blanks 100 cm in length, which were cooled to room temperature.
  • Blanks so prepared were arranged for compression between steel plates manufactured for the purpose, one blank per each pair of steel plates. Compression was carried out in a two-step multiple unit press. In the first step the temperature was +155°C, pressure 4 MPa and compression time 15 min. In the second step, the pressure was 8 MPa and compression time 12 min, and the plates were cooled to a final temperature of +30°C. The blanks were thus compressed into a thick ⁇ ness of 2.0 mm. They were cut into tiles 30 cm x 30 cm or 50 cm x 50 cm in size.
