An electrothermal composite floor with phase change energy storage and temperature control and its manufacturing method

Abstract

The invention discloses a phase-change energy storage and temperature control electric heating composite floor. The phase-change energy storage and temperature control electric heating composite floor comprises an alpha-Al2O3 abrasion-resisting layer, a wood pattern decoration layer, a phase-change energy storage and temperature control layer, a low-temperature electrothermal film, a thermal insulation layer and a substrate layer in sequence from top to bottom. The phase-change energy storage and temperature control layer is formed by composite wood flour which is loaded with polyethylene glycol 1000 in an absorbing mode, and polyacrylic acid polyethylene resin in mixing and hot press molding modes. The phase-change energy storage and temperature control electric heating composite floor is good in temperature control effect and remarkable in energy conservation effect. The invention further discloses a manufacturing method of the phase-change energy storage and temperature control electric heating composite floor. The method comprises the steps that the polyethylene glycol 1000 is absorbed and loaded to the composite wood flour; the composite wood flour which is loaded with polyethylene glycol 1000 is mixed with the polyacrylic acid polyethylene resin, mixing, sheeting, cutting and trimming are conducted, and the phase-change energy storage and temperature control layer is obtained; and the alpha-Al2O3 abrasion-resisting layer, the wood pattern decoration layer, the phase-change energy storage and temperature control layer, the low-temperature electrothermal film, the thermal insulation layer and the substrate layer are glued respectively and then are subjected to assembly, hot pressing gluing molding, mortise machining and surface coating in sequence.

Description

Technical field [0001] The invention relates to the technical field of composite flooring and floor heating, in particular to an electrothermal composite floor with phase change energy storage and temperature control and a manufacturing method thereof. Background technique [0002] Floor heating uses the entire ground as a radiator. The heat medium in the floor radiant layer uniformly heats the entire ground, and uses the ground’s own heat storage and the law of heat radiation to conduct from bottom to top to achieve the purpose of heating. Compared with traditional heating methods, geothermal radiant heating has many characteristics such as comfort, energy saving and environmental protection. The low-temperature ground heat medium forms a gradually decreasing temperature gradient from the bottom of the feet to the head indoors, thereby giving people a comfortable feeling of warming the feet and cooling the head. Ground radiant heating conforms to the fitness concept of "warm fe...

Problems solved by technology

[0016] Although the above research work has achieved some gratifying results, the existing phase change energy storage materials are not integrated with the floor, and need to be stored in a container, which is inconvenient for installation and maintenance.

Moreover, the temperature control effect of the existing phase-change energy storage temperature-adjusting floor is not good, and the effect of saving energy and reducing consumption is not obvious
