Abstract

A waterproof building material, for use in the manufacture of a waterproof paper or felted sheet, is prepared from a bituminous product such as asphalt. The bitumen, heated if necessary to make it fluid, is mixed by violent agitation with an emulsion of water and clay heated to a temperature of from 200 DEG to 400 DEG F., the bitumen being added gradually to the paste or emulsion and more water added as required. In place of asphalt, coal tar pitch, linseed or other oils may be used, and a suitable filler such as sawdust or cork may be added. This "matrix" is then mixed with fibres or paper stock in the heating-engine &c. and made into paper or a fibrous sheet in the usual way. A satisfactory matrix consists of 50 parts of asphalt, 10 of clay and 40 of water, while the finished product may consist of 55-60 parts of asphalt, 11-12 of clay, and 34-38 of fibre. The product is adapted for use as waterproof paper, for roofing and floor coverings, shipping cases, the counters, heels, toes and inner soles of boots &c., receptacles such as tanks, pails, &c., electric insulation &c.
