Abstract:
The object of the present invention is to provide a molding thermoplastic resin material giving resin mold whose quality and value are substantially equal to original resin mold even in a case where said resin mold is recycled. To attain said object, olefin group rubber and/or acrylic rubber to which monomer(s) being the same or similar monomer as (to) monomer(s) composing said molding thermoplastic resin material is(are) graft-copolymerized to give said rubbers compatibility with said molding thermoplastic resin material is(are) added in said molding thermoplastic resin material to improve said equal quality recycling property (property that quality and value are substantially equal to original thermoplastic resin mold even in a case where said thermoplastic resin mold is recycled). Said olefin group rubber and/or said acrylic rubber has(have) excellent thermal stability, heat-resistance, ozone resistance, oxidation resistance, and durability and has(have) effect on improvement of impact resistance for said thermoplastic resin material which is substantially immutable against heat history affected by repeated recycles and said molding thermoplastic resin material of the present invention can be used as a resin material of equal quality resin mold whose quality and value are substantially equal to resin mold using virgin resin material even in a case where said resin mold is recycled.
Abstract:
A method of recycling a molded resin consisting mainly of a thermoplastic resin which comprises adding as a recycle aid agent a rubber-like material (material) which is compatible with the thermoplastic resin as the main component of the molded resin, is moldable after having been mixed with the resin, and has the property of improving impact strength. By this method, impact strength and flame retardancy are recovered or improved.
Abstract:
The object of the present invention is to provide a coating material for recycling a thermoplastic resin mold, wherein said coating material is coated on the surface of said thermoplastic resin mold and said thermoplastic resin mold, discarded, can be recycled without removing the coating film of said coating material. To attain said object, a thermoplastic resin mold is coated with a coating material containing a thermoplastic resin and non-yellowing type cellulose derivative as vehicles, said thermoplastic resin having compatibility with the thermoplastic resin of said thermoplastic resin mold. Said thermoplastic resin mold, surface coated, used, and discarded, can be recycled without removing the coating film of said coating material, and further the resulting recycled thermoplastic resin mold does not degrade.
