    摘要： A two-part sizing system for making colorless, densified fiber pellets of a reinforcing fiber material. The densified product may be advantageously produced by first applying a precursor size composition to reinforcing fiber strands, chopping the reinforcing fiber strands into chopped strand segments, applying a binder size, and densifying the chopped strand segments to form densified fiber pellets. The binder size is formulated using a copolymer of maleic anhydride which generates a product free from discoloration. In the process of making the pellets, the sized chopped strands are densified by tumbling in a rotating chamber for a period of time sufficient to increase their density but insufficient to degrade the fibers to a point where composite articles formed from such pellets have lower tensile or impact strengths than comparable composite articles formed from unpelletized strand segments.

    摘要： A polycarboxy binder composition that contains a dextrin as a co-binder is provided. The dextrin co-binder may be a dextrin, a modified dextrin, a maltodextrin, or combinations thereof. The dextrin may be chemically modified. A pre-binder composition is formed that contains a polycarboxy polymer, a crosslinking agent, and optionally a catalyst. The polycarboxy polymer may be a homopolymer or copolymer prepared from unsaturated carboxylic acids and may be modified to contain one or more vinyl compounds. The crosslinking agent may be a polyol that contains at least two hydroxyl groups. The pre-binder composition may be formed by admixing the polycarboxy polymer, the crosslinking agent, and optionally, the catalyst, in a mixing device. Dextrin may be added to the pre-binder composition in an amount of from 10-75% of the total binder composition. The dextrin binder composition may have a ratio of from approximately 90:10 to 25:75 pre-binder:dextrin co-binder.

    摘要： A two-part sizing formulation that imparts improved strength of reinforced composites including a size composition and a binder composition is provided. The size composition may include one or more coupling agents and one or more film forming agents. The binder composition includes a high acid number copolymer formed from the polymerization of maleic anhydride or maleic acid and at least one other desired monomer and/or a high acid number polycarboxylic acid. In a preferred embodiment, the binder composition includes an ethylene-maleic acid copolymer formed by the hydrolysis of an ethylene-maleic anhydride copolymer. The size composition may be applied to a reinforcing fiber material before the binder size material is applied. The two-part size composition may be applied to a reinforcing fiber material to form a reinforcing fiber product which may then be densified or compacted to form a densified reinforcing fiber product, such as a pellet.
