Abstract

1,255,058. Thick walled mouldings. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Feb., 1969 [2 March, 1968], No. 10827/69. Heading B5A. [Also in Division C3] A thermosetting composition containing a curable plastics material selected from epoxy and unsaturated polyester resins, and at least 80% by weight of mineral filler and thickener if present, is compacted in a mould without curing thereof and is removed therefrom for the cure to be effected. Sheets e.g. with a ribbed surface, shafts, building blocks, beams, straight or curved tubes, tanks, troughs and mouldings provided with stiffening ribs are moulded with thicknesses, greater than 5 mm. Examples are given; (I) a styrene solution of unsaturated polyester resin with benzoyl peroxide and magnesium oxide thickener, mixed with sand, pressed in a mould and then cured at 100‹C.; (II) diamine cured, epoxy resin with silicic acid thickener and sand, cured at room temperature after being pressed in a mould; (III) a cold curing styrene solution of polyester resin with benzyl peroxide paste, amine accelerator, and sand and stone chippings which is compacted in a vertical tubular mould, by a rotary roller head provided with blades for impelling the composition against the mould wall; (IV) a polyester resin with tertiary-butyl perbenzoate, and sand and stone chippings, is compacted in a mould by vibration and pressure applied to the surface and then cured at 150‹ C.; (V) a diamine cured epoxy resin with methyl ethyl ketone, and sand and stone chippings, is pressed in a mould and cured at room temperature or at 60‹ C. The plastics material may also comprise acrylate resins, particularly those containing monomers, and may incorporate extenders such as oil, tar, or coal tar pitch, and has a viscosity of 500 to 10,000 centipoises which may be attained by the use of thickeners. The filler may also comprise quartz, hard rock, and limestone rock. Air may be evacuated from the composition prior to moulding. Cylindrical mouldings may be made within a mould provided with internal forming means e.g. rollers, wherein either or both the mould and forming means rotate and the mould may be vibrated. The mould may be of metal or plastics, or metal lined with plastics.
