Abstract
1,267,967. Mixing synthetic resin ingredients. DYNAMIT NOBEL A.G. 4 June, 1969 [4 June, 1968], No. 28380/69. Heading B1C. [Also in Division C3] In a method of continuously mixing a plastics (especially phenolic) resin containing a foaming agent with one or more solid materials insoluble therein at least part of the solid materials (such as glass fibre or asbestos) is supplied to twin screws 8 having a conveying section of increasing pitch followed by a mixing section having a plurality of radially disposed members arranged uniformly round the circumference of the mixing section 5 and in which the plastics resin is supplied downstream of the point of supply of the solid material, the total residence time of the plastics resin in the conveyer section and in the mixing section being shorter than the time required for foaming of the resin to occur. As shown the solid material is supplied at 1, a hardener in powder form at 2 and a mixture of resin and blowing agent at 3, alternatively the hardenermay be introduced with either the solid material or the resin mixture. The screws may be closely meshing and may have one or more flights and rotate at 150-300 rev./min. The method may be carried out in a protective atmosphere of gas (e.g. fluorochloromethane) soluble in the foamable mixture, in order to exclude air.
