It is characteristic of the products according to the invention that the main component (1) consists principally of previously known, technically unutilised problem waste, such as foam or cellular plastic (2), which has been reduced to a size suitable for the product, but that new, clean plastic can also be used as such or in a suitable mixture with waste plastic. Admixed with the plastic are the previously described natural fibres (3), which regulate and improve the mechanical properties. The outer layers may also be accordingly reinforced by waste or new fibres, fibres from natural-fibre bags or other natural-fibre materials in suitable lengths, etc. All natural fibres (3) such as reed, straw, sisal, hemp, cotton, coconut fibre, jute, linen, manilla, various types of grass, shredded branches and brushwood, etc. may be admixed, and used as such on their own and also together with other natural fibres in order to reinforce the products according to the invention. In order to bind the fibres and improve the adhesive properties between the fibres (3) and the granules (2), suitable dispersion glue or some other binder may be admixed. These agents are classified as binders (4) or additives (5), according to the amount admixed. In order to avoid rotting of the organic fibres, they may be impregnated with a suitable agent, for example the said sodium silicate. An increase in the ... Original abstract incomplete. <IMAGE> |
