Problems solved by technology

However, in the preparation of phase change microcapsules and the application of phase change microcapsule emulsions, various difficulties have been encountered, such as low coverage of phase change microcapsules, low latent heat value, difficult control of particle size, and long preparation cycle. The application process is complicated, and the adhesion after application is poor, which has seriously restricted the practical application of phase change microcapsules.

Abstract

The invention discloses an in-situ cross-linking energy-storage temperature-adjusting functional finishing agent and a preparing method thereof. The in-situ cross-linking energy-storage temperature-adjusting functional finishing agent is prepared from a phase change material, an emulsifying agent, a dispersing agent, silica sol, water, a defoaming agent, waterborne polyurethane, a cross-linking agent and a penetrating agent. The preparing method of the in-situ cross-linking energy-storage temperature-adjusting functional finishing agent comprises the following steps that 1, the phase change material, the emulsifying agent, the dispersing agent, the silica sol and the water are added into a reaction kettle in sequence, stirred and mixed, and the mixture serves as a component A of the in-situ cross-linking energy-storage temperature-adjusting functional finishing agent; 2, the waterborne polyurethane, the cross-linking agent and the penetrating agent are mixed, and the mixture serves asa component B of the in-situ cross-linking energy-storage temperature-adjusting functional finishing agent; 3, the component A and the component B are mixed, and thus the in-situ cross-linking energy-storage temperature-adjusting functional finishing agent is obtained. The prepared in-situ cross-linking energy-storage temperature-adjusting functional finishing agent is obvious in energy-storage temperature-adjusting function, good in storage stability, and low in price, a preparing technology is simple, convenient and controllable, and the in-situ cross-linking energy-storage temperature-adjusting functional finishing agent can be applied to the fields of textiles, architecture, medical treatment, transportation and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an in-situ cross-linking energy storage and temperature-regulating functional finishing agent and a preparation method thereof. Background technique [0002] With the progress and development of society, people's exploration and research and development of functional, intelligent and green materials have become more and more intense. Phase change materials with the function of energy storage and temperature adjustment are just such materials, which have attracted people's close attention. They have great application potential in aerospace, construction, textile, automobile, medical, transportation and other fields. [0003] Microencapsulating phase change materials, that is, encapsulating phase change materials, is a hot research topic at present.
