摘要:
A sealant composition for roofing shingles that includes a base asphalt, a linear and/or a radial copolymer, oil, and a wax is provided. The linear copolymer has an A-B di-block or an A-B-A tri-block structure. The radial copolymer may have an (A-B)n radial structure, where n is at least 4, or a tri-block (A-B-A) radial structure having from 4 to 8 arms. Blocks A and B may individually represent (1) styrene and butadiene or (2) styrene and isoprene. The oil is a petroleum-based oil that both “softens” the asphalt and reduces the viscosity of the sealant composition. The wax may be a bis-stearamide wax. Additionally, the sealant composition may be reacted with elemental sulfur to crosslink the copolymer blend. The sealant composition seals at temperatures lower than conventional sealants and promotes the easy release of the shingle from a shingle bundle.

A siding panel assembly includes an ornamental facing and a first insulation layer made from fibrous insulating material. That fibrous insulating material includes polymer fibers and glass fibers, polymer fibers, natural fibers and mixtures thereof. A method for making the siding panel assembly includes the steps of cutting a groove in and molding a first surface of a sheet of the insulation layer to match in profile a concavity in the ornamental facing and assembling the insulation layer and the ornamental facing.
摘要:
A compound includes a combination of materials for manufacturing a resin based product. The materials include a blend of asphalt and resin. The asphalt functions as at least one of a colorant to change the color of the product and a resin replacement to reduce the amount of resin in the product. The asphalt is included in an amount within a range of from 0.1% to 40% by weight of the compound. A pellet for use in the compound includes from 40% to 90% asphalt and from 10% to 60% resin by weight of the pellet. The asphalt has a softening point from 200° F. to 350° F.
摘要:
A penetration pocket, useful to seal roof openings at protruding pipes or the like, is made of a material compatible with roofing asphalt. The penetration pocket material is asphalt-based with polymeric materials added to impart strength and toughness. Fibrous material may also be added for increased strength. The roofing asphalt, when applied around the penetration pocket, fuses with penetration pocket walls and base, and upon cooling, the penetration pocket and the roofing asphalt are welded together to effect a secure, water-proof joint.
摘要:
A thermosetting asphalt composition includes a blend of an asphalt and an epoxy-functionalized polymer, the epoxy-functionalized polymer being present in an amount within the range of from about 4 to about 30 percent of the combination of asphalt and epoxy-functionalized polymer.

A method for producing asphalt fibers includes supplying molten asphalt to a rotating asphalt spinner, centrifuging asphalt fibers from the asphalt spinner, and collecting the asphalt fibers. The molten asphalt is supplied to the asphalt spinner at a temperature within the range of from about 270.degree. to about 500.degree. F. Also disclosed is a method for integrating asphalt with reinforcement fibers including the steps of establishing a downwardly moving veil of reinforcement fibers, such as glass fibers, and centrifuging asphalt fibers from a rotating asphalt spinner positioned within the veil of reinforcement fibers to integrate the asphalt with the reinforcement fibers. A method for making an asphalt roofing shingle includes the steps of assembling together a mat of asphalt fibers with a mat of reinforcement fibers, coating the assembled mats to form an asphalt coated sheet, applying granules to the asphalt coated sheet, and cutting the asphalt coated sheet into roofing shingles. The invention also includes the asphalt roofing shingle made by this process. Further, the invention includes asphalt highway reinforcement products containing asphalt fibers, and the method of making such products.

摘要:
A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.
