Abstract

The invention discloses a preparation method of a polyurethane-based active heat preservation rigid foam material. A long afterglow rare earth luminous material and a photothermal-conversion energy-storage temperature-control material are adopted and used for preparing polyurethane rigid foam; polyester polyol, polyether polyol, the nanosized long afterglow rare earth luminous material, the photothermal-conversion energy-storage temperature-control material, silicone oil, a catalyst, a foaming agent and a fire retardant are weighed according to proportions and mixed to be uniform, the mixture and modified MDI are together stirred and mixed at a high speed, when it is observed that bubbles are given off, and foam bodies whiten, the mixture is injected into a mold for foaming, set expansion, demolding and curing are conducted in sequence, and the polyurethane-based active heat preservation rigid foam material is obtained. The polyurethane rigid foam material obtained through the preparation method can collect luminous energy under the light condition, and certain brightness in an environmental space can be maintained without illumination at night. In addition, the luminous energy can be stored to be phase transformation energy, when an environment temperature is lower than a specific value, the stored luminous energy is released in the form of heat, and the purposes of certain warming and heat preservation are achieved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a polyurethane-based active thermal insulation rigid foam material. Background technique [0002] As the best thermal insulation material, polyurethane rigid foam thermal insulation composite board has been used in Europe for more than 30 years, and is widely used in various public and civil construction fields.
