TH44176A - ABS substrate extrusion process - Google Patents

Abstract

DC60 (25/05/43) The process for manufacturing extruded ABS products includes the reuse of used ABS to produce recycled ABS that exhibits predefined characteristics, and the extrusion of this recycled ABS to manufacture the final ABS product. The process for manufacturing extruded ABS products includes the reuse of used ABS to produce recycled ABS that exhibits predefined characteristics, and the extrusion of this recycled ABS to manufacture the final ABS product.

Claims (20)

1. The process for manufacturing extruded ABS products comprises the following steps: Recycling used ABS to produce recycled ABS exhibiting predefined characteristics; and extruding this recycled ABS to manufacture the final ABS product. 2. The process under claim 1 in which the recycled processed ABS is extruded to produce ABS sheets. 3. The process under claim 2, which further includes the step of applying a finishing surface layer to this ABS sheet to create a composite sheet material. 4. The process under claim number 3, whereby the decorative surface layer is acrylic. 5. The process under claim number 3, whereby this decorative surface layer is a flooring product. 6. The process under claim 3, whereby the surface layer for this formulation is applied using urethane and coronaplasma treatment. 7. The process under claim 1, whereby the extrusion procedure includes the free-foaming of the recycled, processed ABS. 8. The process under claim 6 in which this free-foaming occurs when the extruded ABS is removed from the extrusion mold. 9. The process under claim number 6 in which the recycled ABS is cooled after being made into free foam. 10. The process stipulated in claim 1, where the recycled ABS is extruded at temperatures ranging from approximately 220°F to 400°F. 11. Extruded ABS products manufactured using this process include the following steps: Recycling used ABS to produce recycled ABS exhibiting predefined characteristics; and extruding this recycled ABS to manufacture the final ABS product. 12. Extruded ABS product as per claim 11, whereby this ABS product is ABS sheet. 13. Extruded ABS products pursuant to claim paragraph 12, where further processes include the application of a decorative surface layer onto this ABS sheet to create a decorative laminated sheet. 14. Extruded ABS products as per claim number 12, where the decorative surface layer is acrylic. 15. Extruded ABS products under claim number 12, where the decorative surface layer is a flooring product. 16. Extruded ABS products pursuant to claim 13 where the surface layer for this finish has been applied by the application of urethane adhesive and coronaplasma treatment. 17. Extruded ABS products pursuant to claim paragraph 11, where the extrusion process includes foaming independent of the processed ABS for recycling. 18. Extruded ABS products pursuant to claim 17, where free foaming occurs when the extruded ABS is removed from the extrusion mold. 19. Extruded ABS products under claim 17 where the recycled ABS is subsequently cooled after being made into free foam. 20. Extruded ABS products under claim 11, in which these recycled ABS are extruded at temperatures ranging from 220°F to 400°F.
