The reversible thermal recording medium of the invention is composed by forming on a substrate a porous reversible thermal recording layer which reversibly shows transparent states and opaque states by cooling after two modes of heating, by means of organic crystal particles dispersed in matrix polymer. One method for manufacturing a reversible thermal recording medium of the invention includes a coating step for applying a paint in which a matrix polymer, organic crystal particles and pore forming particles are contained and at least one of matrix polymer and organic crystal particles is dispersed in a granular form on a substrate to form a coating layer; plus a solvent contact step of eluting the pore forming particles by causing the coating layer to come into contact with a solvent in which the pore forming particles are soluble; and a drying step. Another method for manufacturing the reversible thermal recording medium of the invention includes a coating step of applying a paint in which a matrix polymer and organic crystal particles are contained and at least one of matrix polymer and organic crystal particles is dispersed in a granular form on a substrate to form a coating layer; plus a solvent contact step of causing the coating layer to come into contact with a solvent capable of dissolving the matrix polymer and organic crystal particles; and a drying step.

A method for treating waste printed circuit boards, the method has the steps of: heating up for dry-distilling the waste printed circuit boards having copper foil retaining solder in at least a part of the surface, at a temperature of 250° C. or higher; pulverizing the dry-distilled material of the waste printed circuit boards obtained in the heating step; and separating the pulverized material of the waste printed circuit boards obtained in the pulverizing step, into board resin component and metal component.
摘要:
The present specification discloses a method for treating a thermoplastic resin composition containing a flame retardant comprising a dissolving or dispersing step of bringing the thermoplastic resin composition containing a flame retardant into contact with a solvent to dissolve or disperse at least one portion of the flame retardant into the solvent. According to this, a thermoplastic resin composition containing a flame retardant can be easily separated into a flame retardant and a thermoplastic resin in their original states.

There are disclosed a thermal insulating foamed material, which is superior in thermal insulating property and does not cause deterioration of the thermal insulating property with a time lapse, and a method for producing the same. According to a method for producing a thermal insulating foamed material, a foamed polyurethane resin composition having closed cells, in which at least carbon dioxide is filled, is formed by blowing a raw material mixture containing epoxides comprising at least two members of an epoxide compound having high reactivity with carbon dioxide and an epoxide compound having low reactivity with carbon dioxide, a carbon dioxide fixation catalyst, polyisocyanate, a reactive blowing agent which evolves carbon dioxide by reacting with said polyisocyanate, and a polyol composition. Then, the carbon dioxide in the closed cells is allowed to react with the epoxides in the presence of the carbon dioxide fixation catalyst, thereby to fix carbon dioxide as carbonate compounds.
