Title: Process of producing aminoplast moulding composition
IPC: C08L61/20
Filed: 1960-05-16
Abstract: A process of producing a decorative aminoplast moulding composition for use in making moulded bodies comprises impregnating a filler with a resinous syrup of a thermosetting condensate of an aldehyde and a compound containing aldehyde-reactable amino groups, drying the impregnated composition, then comminuting the dry impregnated composition and homogenizing it upon, if desired, blending it with additives, then increasing the bulk density of the composition to at least 0,5 grams per millilitre by forcibly deaerating it by combined vacuum and compression means without the application of heat, whereupon the thus predensified and deaerated composition is passed into unheated pressure rolls for further densification prior to granulating it.  The compression can be effected by advancing (for example by means of a rotary helical screw) the composition through a chamber of decreasing cross-sectional area.  Another method of deaeration comprises applying a vibrating force to the powder itself by inserting rods within a hopper containing powder about to be fed to the rolls.  Ureides, biguanides, amides, diureides, diurethanes, triazines, diazines and triazoles from which the aminoplast can be prepared are listed.  Also specified are alpha cellulose, regenerated cellulose, cotton, linen, cloth prepared from glass fibres, nylon, wool, silk, polymeric or copolymeric acrylonitrile, wood flour and walnut shell flour as fillers; zinc stearate, glycerol mono-stearate, cresin, carnanba wax, montan wax, zinc palmitate and calcium stearate as mould lubricants; pigments and dyes; and phosphoric, phthalic, maleic, fumaric, tetrachlorophthalic acids or their anhydrides, ammonium chloride or sulphate and sodium phosphate as catalysts.
