Abstract: A method for recycling discarded articles comprising sorting the discarded articles into thermoplastic, thermosetting, and rubber articles, crushing the discarded articles to form thermosetting granules, thermoplastic granules, and rubber granules, and depositing the granules into a molding tool. The molding tool is heated under pressure such that the thermoplastic granules melt, and the molding tool is abruptly cooled to cause the molting material to assume a shape in the molding tool.

Abstract: A water-based synthetic adhesive is composed of the thermosetting acrylic resin and the thermoplastic resin, which are bonded together by an interfacial agent in the presence of water. The adhesive is further composed of an acidic swelling agent capable of causing the adhesive to form a number of air-permeable pores when the adhesive is subjected to heat. The adhesive is still further composed of a consistency promoting agent to facilitate the application of the adhesive. A method for making the water-based synthetic adhesive includes a step in which a mixture containing water and the thermoplastic resin powder is formed. An interfacial agent and the thermosetting acrylic resin are added to the mixture before the mixture is stirred slowly at a predetermined temperature under at least one atmospheric pressure for a predetermined time so that the mixture becomes a paste, which is then subjected to a high-speed grinding at a low temperature for a predetermined period.
