Due to the addition of vinyl chloride to the fragments in the ferric resin powder and the plasticizer, the individual fragments are used in the ferric resin powder; A different colored or transparent dough product is normally advisable to add a stabilizer to the mixture together with the addition zones, which also create a stabilizer for the mixture. : us.vm: iS.

Pieces were made with 5 parts of liquid plasticizer from “. -I ₁ dialphanyl phthalate mixed in a demonstration example 1 for four minutes. Thereafter, each fragment had Thermoplastic fragments from a "wet" coating of plasticizer. Then mass prepared from the following ingredients 15 were added 16 parts of a powder obtained from the following ingredients: Polyvinyl chloride 33 parts polyvinyl chloride (if desired, pigment Dialphanyl phthalate (plasticizer) containing 13 parts te) 100 parts Stabilizer (consisting of lead carbonate and dialphanyl phthalate (plasticizer) 20 parts Dialphanyl phthalate in a ratio of 7: 1) 2 parts ^ao stabilizer (cadmium-barium complex) 2.5 parts Chalk 48.8 parts Stabilizer aid (epoxidized oil) 3 parts Titanium dioxide 3 parts _. _,, ,,.

The above-listed ingredients were mixed in a "Banbury" mixer for four minutes at about 165 ° C, whereupon the powder mixed and the resulting mixture became two-to-one "Wet" plasticizer coating had lumped on the break for minutes at a slightly lower temperature, resulting in a fairly "dry" two-roll mixer and then on precursor product. This was prepared from a two-roll calender at 155 Aufeinem transfer device applied to a vibrator to 16O ⁰ C for a 30, the rolled thickness of 0.15 cm. The slide was peeled off on a conveyor; the layer was left to cool and fed to a granulator. Conveyor was preheated to about 165 ° C and fed into one. The material leaving the granulator, which was operated intermittently at 4.22 kg / l, was sieved to a fragment size that ^{solidified one cm 2} to form elongated floor coverings.

A method according to claim 1, characterized in that (3000 rpm) are mixed in, the mixing is characterized by mixing the vinyl chloride resin powder and high speed three minutes continued for the plasticizer mixed together before, is the temperature to which to 9O ⁰ C because of the 55 fragments are coated with it.
Increased frictional heat; in this way a freely 4. The method according to claims 1 to 3, thereby flowing powder was obtained. indicates that the vinyl chloride resin The fragments and the herbal powder and the plasticizer, as described above, are mixed with a pigment Powders were worked three times in a ratio of 3: 1.
