Abstract
26,363. Karavodine, V. Dec. 24. Resins and resinous compounds.-Consists in producing insulating material with a basis of resinous substances or drying oils. Powdered resin such as bitumen, gum-lac, pitch, or other similar substances which will not readily decompose at 250‹-300‹ C., or drying oils are mixed with 25 to 35 per cent. of powdered sulphur, and to this mixture is added by malaxation, either cold or hot, 30 to 70 per cent. of inert fibrous or pulverulent materials, such as asbestos, sand, or pumicestone. The whole mixture is then heated in a vessel with a loaded cover while still mixing, to 350‹-400‹ C., until it becomes almost solid. The product is compressed in moulds heated to 250‹-400‹ C., or it may be first ground and then compressed. The resins or oils employed may, prior to use in the process, be heated to 300‹-350‹ C., for driving off a portion of their volatile constituents.
