摘要:
A composition of matter for waterproofing a surface of a wall comprising a hydrocarbon resin, a copolymer and a solvent system, wherein said solvent system comprises an aliphatic component and an aromatic component. Also provided are a method for applying the waterproofing composition, as well as a wall that is waterproofed with the composition.
摘要:
A membrane for waterproofing a building component, e.g., a roof or a basement wall. The membrane includes a first layer of asphalt-elastomer blend which preferably is self-adherent to the building component and an overlying layer of plastic film which bears at least one adhesive strip adhered to the plastic film. The membrane is in the form of elongated strips which are overlapped to cover the building component, and the adhesive of each strip ensures a waterproof joint between the laminae of the overlapped strips.
摘要:
An asphaltic coating composition in the form of an emulsion of chemically modified asphalt and a normal, non-modified asphalt in an aqueous emulsification medium. The emulsion can be used as a primer or damp-proof coating and has good adherence to concrete, wooden or asphaltic substrates to yield a coating of excellent physical properties. The chemically modified asphalt and the normal asphalt can be blended prior to emulsification, can be separately emulsified and mixed to form a blended emulsion, or can be individually emulsified in the same emulsification medium.
摘要:
Protective coating solutions for cementitious substrates are disclosed which comprise a minor amount of a cyclohexane based organic solvent on a major amount of an asphaltic material. The asphaltic material is a blend of asphalt with the reaction product of asphalt, a vinyl aromatic monomer, a rubber and an unpolymerized acrylamide.
摘要:
A reinforced composite formed of a bitumen, an elastomer or a plastic reinforced with a filler containing a coating thereon in the form of a chemically modified bitumen. The chemically modified bitumen employed is one formed by reaction of a linking agent reactive with the bitumen and containing groups reactive with the filler so that the chemically modified bitumen undergoes a chemical reaction with the filler to thereby intertie the coated filler with the continuous phase.
摘要:
A bitumen composition modified with an organo silane in which a bitumen such as asphalt is reacted with an organo silane containing ethylenic unsaturation or an organo silane containing at least one hydrogen atom bonded to the silicon atom whereby the organo silanes react with ethylenic unsaturation of the bitumen to chemically bond the organo silane to the bitumen. Also included are bitumens which have been chemically modified by reaction with steam, air, ammonia or aliphatic amines which have been reacted with a silane containing a functional group reactive with the bitumen. Bitumen compositions of the invention are preferably used in the treatment of glass fibers for use as reinforcement in asphalt systems.
摘要:
The use of flake glass in road pavement and repair is disclosed. In particular, we disclose improvements in the formulations of asphalt aggregate wear surfaces, substrate layers and interface layers between the substrate and wear surfaces. In one embodiment we also employ an unsaturated monomer or an unsaturated elastomer.
摘要:
A thermoplastic composition produced by the polymerization of a monomer with unsaturated elastomeric polymers is disclosed. The composition is effective in improving the shrink and gloss of molded thermosetting resin compounds by blending therein.
摘要:
The disclosure teaches the gelling and thickening of matrix forming resin systems by ion-dipole bonds. Suitable ions are introduced into the resin matrix as alkaline oxides or hydroxides. Thermoplastic polymers containing polar groups are used as additives for the thermosetting resins to offset shrink of the thermosetting resins during their crosslinking and curing in the molding operation. In the molded thermoset state of the resin materials, the polar groups provide sites for the improved bonding of paints, as for example, gel coats. The invention has particular advantages in polyester thermosetting resin systems and in the thermoplastic additives that are used therewith. Polar monomers copolymerized with styrene are the preferred thermoplastic additives.
摘要:
A computer-based method for accessing the various individual tools from multiple continuous improvement programs from a single user interface is described. The method includes generating a user interface with a plurality of selectable icons, each icon corresponding to a predefined continuous improvement (CI) cycle step, providing, upon receiving a user selection of one of the CI cycle steps, user selectable process steps to the user interface, providing, upon receiving a user selection of one of the process steps, user selectable tool choices to the user interface, and generating, upon receiving a user selection of one of the tool choices, at least one interactive user interface that provides at least one of an example of the tool choice and instructions relating to the use of the tool choice.
