摘要: A composition is described comprising a resin matrix reinforced with nonamphibole asbestos fiber or other inorganic fibers having similar aspect ratios, fiber diameters and hydrophilic surfaces, in a concentration of 5 to 85 phr, the fiber being coated with a glycol in a concentration of 3 to 75% by weight of fiber. The glycol will have the following properties:(a) liquid and stable up to and at the processing temperature of the resin;(b) liquid at temperatures of less than 50.degree. C. (122.degree. F.);(c) chemically unreactive with the resin;(d) low hygroscopicity; and(e) generally immiscible with the resin at ambient temperatures.Preferably the glycol will be ethylene glycol, propolyene glycol or a polyethylene glycol having a molecular weight not greater than 1500. An internal lubricant may also be used in the composition. Both thermosetting and thermoplastic resins may be used; good results have been obtained with polyvinyl, polyolefin and phenolic resins. The invention comprises the composition itself, the process for its formation, the coated asbestos fiber used for reinforcing the composition and shaped articles, such as pipe, made from the composition.

摘要: Polyester forming reactants of low volatility including an organic acid or anhydride such as trimellitic anhydride, and a polyhydric alcohol, such as dipentaerythritol or pentaterythritol, are admixed at a temperature above 400.degree. F. with partially stabilized polypropylene and asbestos filler to provide a heat stabilized, asbestos-filled polypropylene composition.

摘要: Diatomite-modified membrane and slurry seal mixes having improved properties. An impermeable membrane suitable for protecting cement bridge decks and roadways has from 9 to 14% by weight asphalt, 0.5 to 3.0% diatomite with a preferred diatomite/asphalt ratio in the range of 0.08 to 0.30, with the balance being fine aggregate (sand). This membrane can be placed by conventional paving equipment, can withstand temporary traffic loading prior to installation of a wearing course, can be preformulated in sheets, and is a crack resistant (i.e., self-healing) under normal traffic loads. Also disclosed is a slurry seal cold mix with improved abrasion resistance, adhesion/cohesion, and tensile strength. With these improved characteristics, slurry seals can be useful as bridge deck and roadway membranes in addition to its standard overlay uses.
