摘要:
A method for manufacturing an hydraulic binder or thermoplastic binder containing product including the steps of impregnating the binder into a flexible open cell polymeric foam element by compressing the foam element to exclude air from the open cells and then releasing the compression with the foam elements whilst in contact with the binder so that the binder penetrates and becomes contained in the open cells of the foam elements as it regains its shape. Alternatively impregnating the binder into the foam element from one side under pressure so that the binder penetrates and becomes contained in the open cells of the foam and then allowing the binder to set or hardened and dry to form the product. The product is particularly suitable as a building element.

A method of making a finished product includes the steps of providing a feedstock comprising a polymer component comprising 5 to 100 parts by weight of a polymer selected from the group consisting of polyethylene in particulate form, polyvinyl chloride in particulate form, and a mixture of polyethylene and polyvinyl chloride both in particulate form; 0 to 95 parts by weight of polystyrene in particulate form; an extender, and optionally reinforcing fibres or particles; mixing the feedstock with a thermosetting resin selected from an unsaturated polyester resin in liquid form and a catalyst for the polyester resin and an epoxy resin in liquid form and a catalyst for the epoxy resin; and subjecting the product to suitable conditions of temperature and pressure to cause the polyethylene and/or the polyvinyl chloride and the polystyrene, if present, to melt and the thermosetting resin to set to form the finished product, e.g a shutter board.
