#$%^&*AU2020101280A420200813.pdf#####ABSTRACT Disclosed is a method for preparing a recycled composite type building thermal insulation material, including: processing a waste organic resin into organic resin particles, putting the organic resin particles into a phase-change material solution, and after a phase-change material enters open pores of the organic resin particles and is changed into a solid state, putting the organic resin particles into a polyurethane mixed material, and taking out the organic resin particles to form organic resin particles having a phase-change function; then, mixing the organic resin particles having the phase-change function with a recycled fine aggregate and recycled particles that are obtained by crushing waste concrete, and other materials to prepare into a light inner core layer; preparing an inorganic foaming building thermal insulation material by using materials such as the recycled fine aggregate, the recycled particles and ordinary Portland cement; and at last, forming the recycled composite type building thermal insulation material through the inorganic foaming building thermal insulation material and the light inner core layer. The present invention not only recycles the waste organic resin and the waste concrete, but also has the advantages of small self weight, good thermal insulation performance and capability of automatically controlling the temperature.
