Problems solved by technology

The phase change material obtained by this method should not be directly used as floor tiles, because the phase change material is directly added to the premix, it is easy to seep out from the phase change material, the service life of the phase change material is short, and its strength, thermal shock resistance Poor performance and wear resistance, not suitable for use as floor tiles

Embodiment 1

[0037] The 25 # Add 50 parts of paraffin to a magnetic constant temperature stirrer, heat to 35°C, and adjust the speed to 500 rpm after the paraffin is completely melted; add 50 parts of cement, 40 parts of fly ash, and 10 parts of γ-alumina to the stirrer, and stir at a constant speed for 60 minutes , to prepare a phase change energy storage material, and take it out for later use. The latent heat value of the phase change energy storage material measured by differential scanning calorimeter (DSC) is 65.5 kJ / kg.

[0038] Then heat the double-roller closed rubber mixing machine to 90°C, put 100 parts of PEBA elastomer and 100 parts of nano-scale calcium carbonate with surface organic treatment into the double-roller closed rubber mixing machine for blending, the speed is 50rpm, and knead 30min into a premix. Take 50 parts of a phase change energy storage material with a phase change latent heat of 65.5kJ / kg, mix it into the premix in a double-roller closed rubber mixer, adj...

Embodiment 2

[0049] In Example 1, the surface-treated nano-scale calcium carbonate was replaced by surface-organized nano-scale magnesium hydroxide, and the remaining materials and operating conditions were unchanged to obtain shaped floor tiles. The flame retardant performance is measured by the oxygen index method / GB / T2406-93 (the same below), and the oxygen index of the floor tile is only 24; moreover, there is a certain amount of smoke generated during the combustion test. Compared with it, the flame retardancy and smoke generation of the floor tiles prepared in Example 1 are obviously much better.

Embodiment 3

[0051] In Example 1, after step (1) is reconciled, the latent heat of phase change is 150.2kJ / kg of 25 # Replace 50 parts of paraffin with 80 parts, and keep other conditions unchanged, the latent heat value of the prepared phase change energy storage material is 83.2kJ / kg. Then follow step (2) to replace 50 parts of the phase change energy storage material with a phase change latent heat of 83.2kJ / kg into 80 parts, and keep the rest of the conditions unchanged. 59.8kJ / kg, oxygen index 26.

Abstract

The invention discloses a phase-change energy storage floor tile and a manufacturing method thereof. According to a formula, the floor tile comprises: 50-100 parts of a phase change material, 100 parts of an inorganic flame retardant and 40-100 parts of a high polymer elastomer, wherein the phase change material consists of: 30-70 parts of cement, 30-50 parts of fly ash, 5-20 parts of gamma-alumina, and 50-100 parts of a phase change substance. The floor tile is manufactured by: first adsorbing the phase change substance into a porous substance composed of cement, fly ash and gamma-alumina in a proper portion, and then subjecting the adsorbed porous substance, the flame retardant and the high polymer elastomer to mixing. The obtained floor tile has the characteristics of high strength, good thermal shock resistance and wear resistance, difficult breackage, stable chemical properties, and strong thermal storage / refrigeration capability, and can prevent the phase change substance from seeping from the energy storage floor tile. And the phase change material has the advantages of long service life, good flame retardance and environmental performance.

Description

technical field [0001] The invention relates to a civil building material, in particular to an environmentally friendly, flame-retardant floor tile with phase-change temperature regulation and energy storage and a manufacturing method thereof. Background technique [0002] As an emerging functional material, phase change energy storage material (PCM) works on the principle of absorbing (or releasing) the latent heat of phase change by using the phase change process of the material to realize the absorption (or release) of energy in the environment. In turn, it can store heat or cool down, so as to achieve the goal of energy storage. Phase change energy storage is a type of latent heat energy storage. Compared with sensible heat energy storage, it has the characteristics of high energy storage density, approximately isothermal energy storage (or energy release) process, and easy control of the process. It is very suitable for solving energy supply and demand. Imbalance and i...
