Abstract

The invention relates to a high-light-reflection phase-change heat storage coating for textiles and a preparation method of the high-light-reflection phase-change heat storage coating. The coating comprises an outer coating, an inner coating and a middle layer between the outer coating and the inner coating, wherein the outer coating is a waterborne polyurethane modified layer; the middle layer is a waterborne polyurethane coating filled with a modified light reflecting material; and the inner coating is a coating which comprises the components of water-based phase change polyurethane and modified phase change microcapsules. The coating has high near-infrared reflectivity and hemispherical emissivity, the problem that the textile is overheated in summer is greatly reduced, the phase change enthalpy value of the coating in the coating is greatly increased, the temperature of the textile can be effectively controlled, and the situation that an existing textile is cold in winter and hot in summer is greatly relieved.

Description

technical field

[0001] The invention belongs to the technical field of textiles, in particular to a high-light reflection phase-change heat storage coating for textiles and a preparation method thereof. Background technique

[0002] Textiles are easily affected by the environment. In summer, the temperature of textiles rises sharply after being irradiated by the scorching sun, even reaching above 80°C; in winter, the temperature of textiles is very low. Therefore, improving the thermal management of textiles is essential to achieve better comfort, and the emergence of phase change heat storage technology and heat reflection technology is conducive to reducing energy consumption.

[0003] Phase change heat storage technology refers to the characteristics of materials that absorb and release heat during the change of physical state to store and release heat. The temperature remains constant during the phase change process, so it plays a great role in the field of temperature c...
