Abstract
A resinous substance, such as that known under the Registered Trade Mark "Vinsol," for use in making fibro-cement products (see Group V) is prepared from ground pinewood by extracting with a coal tar hydrocarbon solvent, e.g., benzol or toluol, removing the volatile constituents and treating the residue with a petroleum hydrocarbon solvent, such as gasoline, to dissolve out the resin. The pine wood may be initially treated with live steam to remove the volatile constituents, including turpentine and pine oil.ALSO:A fibro-cement product formed by extrusion, particularly pressure pipe, is composed of Portland cement and asbestos fibres, with or without silica, and .01-.05, preferably .02-.04, per cent. of the dry weight of cement, of a petroleum hydrocarbon insoluble fraction of pine wood resin, such as that known under the Registered Trade Mark "Vinsol" (see Group III). The resinous substance may be incorporated in solid form during the grinding of the cement or, after saponification with caustic soda, added in liquid form to the water used in making the cement mixture. The pipe &c. may be set by autoclaving, preferably at steam pressures up to 120 lbs. sq. in. and temperatures up to 170 DEG C., or in water without autoclaving. In the latter case, silica may be omitted.
