The invention belongs to the technical field of recycling of heat generating agents for heating pads, in particular to a preparation method for recycling waste and old heat generating agents for heat-generating patches and regenerating intumescent flame retardants. It can endow coatings, rubber, plastics and other materials with certain mechanical properties and heat resistance, and at the same time form a carbon layer with barrier properties during combustion, endow the materials with good flame retardant properties and smoke suppression functions, high oxygen index, heat Low release rate, the use of ferric hydroxide to synergize smoke suppression and flame retardant, a wide range of raw material sources, low cost, green recycling, to solve waste pollution, can be widely used in architectural coatings, rubber and plastic products, etc. The problem of recycling, treatment and utilization of exothermic agent, expand the space for recycling and reuse of exothermic agent waste, and improve the ecological cycle chain of the heating paste industry, generate new economic added value, and be conducive to green environmental protection. |
