Problems solved by technology

If fibrous filler material has been incorporated into polymer waste that has not yet been melted, as is the case in document EP2525951B1, then the mixture can no longer be purified by filtration after melting, since the incorporated fibers would remain at the filter unit , and the filter will quickly clog

Abstract

The invention relates to a method and to a device (1) for producing a filled polymeric composite material (7), which contains a polymeric carrier material (2) and a fiber material (2) as a filling material, wherein the polymeric carrier material preferably contains a main fraction of recycling polymer waste (3). The device (1) comprises a first extrusion apparatus (10), which has an inlet (11) for the polymeric carrier material and an outlet (12) for the melted polymeric carrier material, a melt-processing apparatus (40) for cleaning the melted polymeric carrier material, which melt-processing apparatus is connected to the outlet of the first extrusion apparatus, and a second extrusion apparatus (20). The second extrusion apparatus has a melt inlet (26), which is connected to the exit (42) of the melt-processing apparatus, and a fiber material inlet (27) for the fiber material, which fiber material inlet is arranged upstream of the melt inlet. The second extrusion apparatus comprises at least one degassing apparatus (31, 32).

Description

technical field [0001] The present invention relates to a method and a device for producing a filled polymer composite comprising a polymeric matrix material and a fibrous material as filling material, the major part of the polymeric matrix material being preferably recycled polymer waste. The device comprises a first extrusion device for melting the polymeric matrix material, the first extrusion device having an inlet for the polymeric matrix material and an outlet for the molten polymeric matrix material. The melt preparation device for purifying molten polymeric matrix material has an inlet connected to the outlet of the first extrusion device, and an outlet for purified polymeric matrix material connected to the second extrusion device. Background technique [0002] Methods of producing fiber-filled polymers are known from the prior art. For example, in document EP2525951B1 fibrous material from wood processing or paper and pulp conversion, respectively, is mixed with u...
