ENERGY-STORING TEMPERATURE CONTROL MATERIAL AND PREPARATION METHOD AND APPLICATION THEREOF

The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

Method of pouring polyisocyanurate foam directly onto a facer to improve cell orientation and density stratification

A method of forming a polyisocyanurate foam board includes providing a polyol and adding an isocyanate to the polyol to form a polyisocyanurate foam. A first inner surface of a first facer material is treated with a first flow of hydroxyl containing molecules. A second inner surface of a second facer material is treated with a second flow of hydroxyl containing molecules. The polyisocyanurate foam is coupled to the first treated inner surface and the second treated inner surface such that the polyisocyanurate is sandwiched between the first facer material and the second facer material, thereby exposing opposing outer surfaces of the polyisocyanurate foam to the hydroxyl containing molecules. A density of a medial portion of the polyisocyanurate foam is greater than a density of the polyisocyanurate at the opposing outer surfaces.
