see more details were constructed to measure the change of temperature rise from 0 to 35 min in normal electric floor and RPIB at room temperature of 20°C. Two closed models were established to measure the length of time during which the temperature in the model was lowered from 40°C to 20°C; a thermodynamic model of a solid wood composite rigid polyurethane thermal insulation board was established through analysis of heat transfer theory. A solid wood composite polyurethane insulation board floor model with oak and poplar wood as the decorative panels was produced, and a temperature rising contrast experiment was performed within 0-30 min. Result: In the temperature rising experiment, the floor temperature of solid wood composite rigid polyurethane thermal insulation board floor was lower than the temperature of ordinary electric floor per unit time, and the temperature difference between the two

see more details reached 2.0°C after 35 min. In the thermal insulation experiment, the ordinary electric floor was reduced from 40°C to 20°C for 37 min, and the RPIB was lowered from 40°C to 20°C for 55 min. Conclusion: The performance of the hard polyurethane material with low thermal conductivity is very excellent in retarding the heat transfer, so that the RPIB has better thermal insulation performance than the ordinary electric floor. The high decorative panel's electrically heated floor makes the heat conduction more efficient.
