WATERPROOF BITUMINOUS ROLL MATERIAL AND THE METHOD OF ITS MANUFACTURE Russian patent published in 2007 - IPC C08L95/00 E04D5/06 

FIELD: construction materials industry; public health; medicine; production of the elastic composite material.

SUBSTANCE: the invention is pertaining to the waterproof bituminous roll material and the method of its manufacture. The invention presents the waterproof bituminous roll material containing at least one reinforcing base and the applied on the base both sides bituminous layer. The technical result of the invention is development of the bituminous roll material simplifying its reprocessing after expiration of its service life on the roofing. The water-insulation bituminous roll material contains at least one reinforcing base and the bituminous coating layer applied on the both sides of the base. The reinforcing base is manufactured out of the organic material with the fusion point of 140-220°С, which is made in the form of the nonwoven fabric or the net, or in the form of the net manufactured out of the mineral-glass or the organic filaments having the fusion point exceeding 220°С. The net made out of the organic filaments has the space interval between the opposite filaments in the cells is equal to 1-10 mm or the cells diameter is equal to 1-10 mm. For the net, which is made out of the mineral-glass filaments, this space interval between the opposite filaments in the cells is equal to 1.6-10 mm or the cells diameter is equal to 1.6-10 mm. The invention also presents the method of production of the waterproof bituminous roll material.

EFFECT: the invention ensures development of the bituminous roll material simplifying its reprocessing after expiration of its service life on the roofing.
