Abstract

Solid filler material is incorporated in plastics, for example, cellulosic plastics and phenolic-aldehyde resins, by forming a solution of the plastic, forcibly circulating the solution in a confined path while introducing the filler, <PICT:0577920/IV/1> admitting air to the solution along with the filler, and evaporating solvent from the solution. The filler may be subjected to a grinding action in the solution, for example, by means of the gear pump used to circulate the mixture. The solution of the plastic may be prepared by circulating the solvent in a confined path and introducing the plastic and continuing the circulation until the plastic is dissolved. In an example, a solvent such as acetone, alcohol, or ether-alcohol from the tank 11 is run into the mixing vessel 10 and then caused to circulate through pipe-lines 14 and 29 by means of the gear pump 22. The plasticiser and then cellulose acetate are introduced into the system through the hopper 21, and when the latter is dissolved the filler, for example, lead carbonate or iron oxide, is introduced in the same manner. Due to the suction caused by the pump, air is drawn into the system together with the filler, and the excess gases escape through the pipe 30 and are condensed in 32. When dispersion is complete the excess of solvent is withdrawn from the system by means of the pump 31 and condensed.
