发明名称 Composite intermediate, method for forming same, and use of the composite intermediate
摘要 A web-type composite intermediate is formed from fibers and plastic. The composite intermediate is formed by wet web formation from a substantially homogeneous liquid mixture which contains natural fibers, plastic particles having a diameter of less than approximately 1000 μm, and an agent that improves compatibility between natural fibers and plastic particles. In addition, a method for forming a composite intermediate and the use of the composite intermediate are also described.

主权项 1. A composite intermediate which is formed from fibers and plastic, the composite intermediate being formed by wet web formation from a substantially homogeneous liquid mixture comprising: natural fibers selected from the group consisting of wood-derived fibers, mechanically defibrated fibers, chemical pulp fibers, cellulose fibers of natural fibers, and mixtures thereof, thermosoftening plastic particles having a diameter of less than approximately 1000 μm, and an agent that improves compatibility between the natural fibers and plastic particles, said agent increasing adhesion between the natural fibers and the plastic particles and being compatible with reactive groups of the natural fibers and plastic particles, wherein the agent that improves compatibility is styrene maleic anhydride, and wherein the liquid mixture comprises less than 3 wt % dry matter of the agent.
