| titleOfInvention | Additives, treated polymeric materials, method and device for the coating and/or mixing of the polymeric materials |
| abstract | The present invention relates to an additive for the lubrication of granular polymeric materials comprising a) 20 to 40% by weight of aluminum stearate, typically containing free fatty acid in a total amount of 1.0 to 10.0% by weight, based on the amount of said aluminum stearate, (b) 1 to 25% by weight of zinc stearate, (c) 35 to 79% by weight of at least one amide wax selected from N,N'-diamides of ethylene diamine and saturated C16 to C32 carboxylic acids whereby optionally up to 50% by weight based on the amount of (c) of said N,N'-diamides can be replaced by at least one compound selected from stearyl erucamide, erucyl erucamide, oleyl erucamide, stearyl stearamide, erucyl stearamide, stearyl stearate and C27 to C45 ketones, and (d) a metal hydroxide in an amount sufficient to convert at least 20% of the free acid contained in the aluminum stearate into the corresponding metal salt. Furthermore, the present invention relates to the treated polymer materials and to a method for the treatment of polymer materials wherein the granulated technical plastic materials are introduced through an inlet (22) into a container (10) wherein a fluidizing bed (16) is generated by air flowing in upward direction. By a spraying means (28), an additive is sprayed in finely distributed form into the fluidizing bed (16) in such a manner that the additive deposits on the granular polymeric particles. Within the fluidizing bed (16), the polymeric granules pass from the inlet (22) to an outlet (26) to be discharged therethrough. The method is carried out in continuous operation and is particularly suited for the coating of polymeric materials which are to be processed by injection moulding. |
