    摘要: A modified coal tar useful in roofing applications, containing coal tar, a nitrile butadiene rubber, and in some instances an effective amount of a plasticizer is prepared by heating the coal tar to a molten temperature, adding the rubber in powder form and agitating the material in a suitable high shear mixing apparatus until adequate phase inversion occurs between the polymer and the coal tar phase. After preparation, the material is cooled in containers until use, at which time it is heated to a flowable temperature and applied using a roofing mop or squeegee. Effective plasticizers include the alkyl esters of di-functional carboxylic acids, such as di-octyl adipate and di-octyl phthalate.

    摘要: Emulsions of asphaltic materials, such as asphalt or asphalt blends with polymers, in water using copolymeric anionic emulsifiers are disclosed. The copolymeric anionic emulsifiers use ionizable carboxyl groups as their hydrophilic moiety. The emulsions using these copolymeric emulsifiers are stable, allowing them to be used anywhere where asphalt or modified asphalt is used as a sealant, coating, or binder. These emulsions can also be mixed with polymer latices, pigments, fibers, fillers and other additives to impart particular properties specific to the type of application, i.e., pigmented flexible coating compositions, non-sag sealer and sealant compositions, water borne adhesive compositions, etc., for use in construction and industrial fields. These asphalt emulsions have better freeze-thaw stability, higher solids contents, and wider applicability to polymer modified asphalt compositions than prior art emulsions.

    摘要: A composite substrate (10) is prepared for reinforcing a bituminous roofing material by securing together a carrier web (12) with a first set (14) of fiberglass rovings bundles and a second set (16) of fiberglass rovings bundles. The carrier web will have a pair of opposed planar surfaces. The web will define a machine direction and a cross machine direction for the substrate, with the first and second sets of rovings bundles each positioned in parallel relationship, with the longitudinal axes defined by the individual rovings of the two sets being in non-parallel relationship to each other when viewed normal to the plane of the web. The bundle sets are maintained in the spaced apart parallel relationships and the non-parallel angular relationship by the adhesive, stitching or other conventional method of securing which holds the substrate together. If a stitching machine is used, the preferred yarn (18) would be a polyester yarn. The preferred web is a woven polyester mat and the preferred rovings bundles will be 1800 yield or heavier. After preparation, this substrate is dipped in molten bituminous material to provide a web of reinforced roofing material in which the substrate is embedded in a continuous matrix of the bitumen.
