Description

A COMPOSITE MATERIAL
Technical Field
The present invention relates to a composite material by the production of which recycled materials are used.
Prior Art
Refrigerators are appliances enabling particularly food products to be kept fresh for a long time by keeping them cold. These appliances comprise an internal volume, i.e. a cabinet, in which the items desired to be kept cool are placed. Thermally insulating said cabinet from the environment is important for maintaining the cold in the cabinet.
Hard polyurethane foam is used as insulation material in refrigerators, deep freezers and in construction industry. The unused portions of said hard polyurethane foam are utilized as waste, and are usually collected by waste collection organizations for a certain fee. This material creates a critical threat for the environment when not recycled.
State of the art European patent document no. EP1149862 mentions polyurethane foam production for refrigerators and recycling of the foam material.
State of the art United States patent document no. US2009170970 mentions pulverization of foam and utilization of said powder in foam formulation.
None of the state of the art documents include a solution such as the one in the present invention.
Brief Description of the Invention
The aim of the present invention is to realize a composite material by the production of which recycled materials are used.
Another aim of the present invention is to realize a composite material with reduced production costs.
Detailed Description of the Invention
The composite material of the invention comprises at least one polymer resin and, pulverized waste polyurethane as filler. At least a portion of the composite material of the invention comprises recycled waste polyurethane.
In the preferred embodiment of the invention, the waste polyurethane is pulverized by fine grinding. A resin suitable for the material intended to be produced, is introduced into an extruder, and the resin is enabled to melt by increasing the temperature of the extruder at least to the melting temperature of said resin. The pulverized polyurethane is added into the melted resin, and mixed. Mixing is continued preferably until said mixture becomes homogeneous, thereby obtaining the composite material.
In an embodiment of the invention, at least one filler may be added, which improves the mechanical and physical properties of the formed composite material by enhancing the interaction of the polyurethane powder and the resin. In an embodiment of the invention, at least calcium carbonate is used as filler, but the fillers which may be used are not limited to this.
By means of using polyurethane waste in producing the composite material of the invention, the proportion of resin and additive/filler materials required in a composite material are reduced, thereby decreasing the production cost of the composite material. Moreover, the materials produced using the composite material of the invention weigh less since the density of the pulverized polyurethane foam is lower than mineral based fillers.
Polyurethane foam waste can be utilized in the production thanks to the composite material of the invention, thereby saving waste disposal costs and enabling protection of the environment by recycling a waste material.
In an embodiment of the invention, plastic composite material is produced by combining polyurethane foam waste with polypropylene resin.

Claims (3)
