Abstract

The invention belongs to the technical field of energy storage materials, and specifically relates to a multi-layer heat storage and preservation microcapsule applied to fabrics and a preparation method. The multi-layer heat storage and preservation microcapsule is composed of an inner core, an inner shell layer, a middle shell layer and an outer shell layer, the inner shell layer is arranged between the inner core and the middle shell layer, the middle shell layer is arranged between the inner shell layer and the outer shell layer, and the outer shell layer is arranged on the outermost layerof the microcapsule. The core is a phase change energy storage material, the inner shell layer is a cross-linked product generated by a reaction between 1,3,5-trimesoyl chloride and mercapto-amino silicone oil, the middle shell layer is a cross-linked product generated by a reaction between mercapto and carboxyl vinyl silicone oil, and the outer shell layer is a cross-linked product generated by areaction between carboxyl and an aziridine crosslinking agent. The shell of the multi-layer heat storage and preservation microcapsule has high thickness and strength and good temperature resistance,and has good stability when being applied to spinning.

Description

technical field [0001] The invention relates to the technical field of energy materials, in particular to the technical field of energy storage materials, and relates to a multilayer heat storage and heat preservation microcapsule applied to fabrics and a preparation method thereof. Background technique [0002] Heat storage and heat preservation microcapsules are coated with phase-change energy storage materials to form a structure in which the core is phase-change energy storage materials and the outer shell is coating materials. It can store heat at higher ambient temperatures and improve coolness when applied to textiles. When the ambient temperature drops, it releases the stored heat and improves heat preservation, so it has the characteristics of energy saving and environmental protection. [0003] At present, heat storage and heat preservation microcapsules are generally prepared by emulsifying phase change energy storage materials, and then forming a crosslinked poly...
