TWO-PART SIZING COMPOSITION FOR REINFORCEMENT FIBERS |
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 blocked isocyanate and a copolymer formed of a maleic anhydride and at least one other monomer copolymerizable therewith. In a preferred embodiment, the binder composition includes an ethylene-maleic acid copolymer formed by the hydrolysis of an ethylene-maleic anhydride copolymer. In an alternate embodiment, the size composition includes a coupling agent, a lubricant, and a wetting agent. 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 which may then be densified or compacted to form a densified reinforcing fiber product, such as a pellet. |
