    摘要: A sizing composition for reinforcement fibers that includes a cationic modified polyurethane dispersion, one or more silane coupling agents, and at least one lubricant is provided. The cationic modified polyurethane dispersion includes a dual end-capped polyurethane selected from a silane-terminated polyurethane, a ketoxime-terminated polyurethane, or a hybrid silane/ketoxime-terminated polyurethane where one end of the polyurethane is terminated with a silane group and the opposing end is terminated with a ketoxime group. The size composition is applied to reinforcement fibers and formed into chopped strand, wet-laid mats that can be used for a variety of purposes, including roofing products. Chopped strand mats formed from fibers sized with the inventive sizing composition maintains or improves the dry tear strengths and wet strengths compared to chopped strand mats made from fibers sized with a commercial sizing composition that does not contain a modified cationic polyurethane dispersion (e.g., SPUD).

    摘要: A composite material containing wet chopped strand fibers, gypsum, and a polymer material is provided. The wet fibers are filamentized within the polymer material. In exemplary embodiments, the wet chopped strand fibers are wet-used chopped strand glass fibers. The gypsum may be α-gypsum, β-gypsum, or combinations thereof. In at least one embodiment, the polymer is a urea-formaldehyde resin. The composite material may contain a facing layer on at least one exposed major surface of the composite material. A method of forming a composite material that includes mixing gypsum with a polymer material to form a substantially homogeneous matrix and adding a sufficient quantity of wet-used chopped strand fibers to form the composite material is also provided.

    摘要: A size composition for reinforcement fibers used to form non-woven mats that contain variable amounts of individual filaments dispersed from chopped reinforcement fiber bundles is provided. The size composition contains a polyvinylamine film former, one or more silane coupling agents, and, optionally a lubricant. The size composition works in conjunction with the whitewater components in a wet-laid mat forming process to disperse individual filaments from the bundles of chopped fibers. The whitewater contains an anionic polyacrylamide viscosity modifier and/or a cationic or non-ionic amine dispersant (e.g., ethoxylated amine). The presence of a cationic or non-ionic amine in the whitewater disperses individual filaments from the chopped glass fiber bundles. The greater the amount of cationic or non-ionic amine present in the whitewater, the greater the amount of fiber dispersion. The absence of a cationic or non-ionic amine and the presence of an anionic polyacrylamide viscosity modifier maintain full bundle formation integrity.
