THERMAL STORAGE FLOOR MATERIAL AND THE METHOD PREPARATING THEREOF

摘要

A method for producing a heat-storing flooring material using a phase change material is provided to prevent leakage of the phase transition material during heat storage and discharge, thereby storing heat in a phase change temperature range for a long time. A method for producing a heat-storing flooring material including a mat, a flooring sheet or a sheet for a heat insulation casing comprises the steps of: (i) mixing a polymer resin with a phase transition material in a weight ratio of 30:70 to 70:30; (ii) forming a composite from the mixture by using heat, followed by extrusion; (iii) molding the extruded material in a roller; and (iv) carrying out crosslinking. The phase change material includes a compound represented by the formula of CnH2n+2 alone or in combination, wherein n is 10-15.
