摘要:
The invention relates to composite compositions having a matrix of polymer networks and dispersed phases of particulate or fibrous materials. The polymer matrix contains a polyurethane network formed by the reaction of a poly- or di-isocyanate and one or more saturated polyether or polyester polyols, and an optional polyisocyanurate network formed by the reaction of optionally added water and isocyanate. The matrix is filled with a particulate phase, which can be selected from one or more of a variety of components, such as fly ash particles, axially oriented fibers, fabrics, chopped random fibers, mineral fibers, ground waste glass, granite dust, or other solid waste materials. The addition of water can also serve to provide a blowing agent to the reaction mixture, resulting in a foamed structure, if such is desired.
摘要:
A continuous forming apparatus for molding foam material into foam products that includes a first endless belt and a second endless belt that cooperates with the first endless belt to mold the foam material. The continuous forming apparatus may also include a first plurality of cleats and a second plurality of cleats opposed to the first plurality of cleats that support the first endless belt and the second endless belt respectively. The first plurality of cleats may include a three-dimensional abutment surface that provides transverse and lateral support to the first endless belt. Additionally, the continuous forming apparatus may include a first frame disposed to support the first plurality of cleats, a second frame disposed to support the second plurality of cleats, and a drive mechanism for imparting motion to the first endless belt, the second endless belt, the first plurality of cleats, and the second plurality of cleats.
