Definitions

  • the present invention is directed to shaped plastic roof tiles, particularly those shaped to have the appearance of slate tiles and the process for manufacturing the tiles.
  • roofing materials There are many different roofing materials presently in use including wood shakes and shingles, asphalt shingles, clay tiles, metal panels and slate tiles. While asphalt shingles are the most commonly utilized because of their lower cost and weight, other materials are more preferred for their aesthetic appeal . Amongst such materials, clay and slate are particularly desirable for their longevity and appearance. Clay and slate do however have drawbacks. There is only a limited supply of slate which makes it very expensive as a roofing material . In addition, clay and slate are extremely heavy materials requiring that the roof on which they are to be installed be specially engineered to support the weight, which also increases the cost of the finished roof.
  • plastic tiles having the appearance of clay and slate but which do not have some of the drawbacks.
  • plastic tiles are of relatively low weight and generally do not require a specially engineered roof, being able to be installed on standard roof construction.
  • Plastic also has an advantage of being able to be formulated to have a long life. Examples of such plastic tiles are described in US Patents 5,992,116; 5,946,877; 5,630,305; 5,615,523 and 5,295,339 among others .

  • the densification operation may be accomplished by any method known in the art such as the use of a screw extruder or utilizing suitable knives in a chopping apparatus.
  • suitable knives the heat generated by the friction between the knives and the polymers melts the plastic and causes the plastic to stick to the rubber particles.
  • the mixture may be cooled with water then ground into smaller particle sizes. These smaller particle sizes are remelted, and molded using compression molding or injection molding.
  • compression molding the particles are melted and placed into a compression mold having the suitable shape and features for the roof tile and then pressed to form the final roof tile.
  • the roof tile may also be formed by an injection molding operation utilizing a suitable injection mold.
  • the use of the chlorine containing polymer results in a chlorine content in the formulation in the range of 1 to 65 percent by weight.
  • the presence of the chlorine provides for increased resistance of the tiles in a fire situation. Should the tiles be exposed to an open flame, hydrogen chloride would be released during the burning of the chloride polymer. Further flame development would be interrupted by the hydrogen chloride reaction with hydrogen atoms and hydroxyl radicals thus providing a suitable fire rating to the roofing material.
  • the presence of the chlorine also reduces dripping of the thermoplastic elastomer especially polyolefins during burning.
  • the shaped roofing tiles of the present invention provide for an economical manufactured roof tile that replicates the classic look of more expensive materials such as slate without the added weight or cost of traditional materials.
  • a roofing system utilizing the roofing tiles of the present invention is as easy to install as conventional asphalt shingles and requires no added substructure as would be the case for slate tiles as well as some other imitation tile.
