Abstract

The preparation method of the water-based nano-microcapsule emulsion disclosed by the invention is obtained by dispersing nano-microcapsules in water. The nano-microcapsules are composed of a core material and a shell material wrapped outside the core material. The core material is far-infrared nano-ceramic powder, and the shell material for polyurethane. The far-infrared nano-ceramic is wrapped with polyurethane and uniformly dispersed in water to obtain a uniformly dispersed water-based nano-microcapsule emulsion. Polyurethane can not only effectively wrap nano-ceramic powder, but also realize the uniform dispersion of microcapsules in water, and can enhance the adhesion between microcapsules and substrates, greatly improving the durability and washing fastness of functional textile materials. The emulsion can be applied to functional textiles and other heat storage and heat preservation materials. After functional finishing of textile materials or other heat storage and heat preservation materials, the obtained functional textiles and other heat storage and heat preservation materials not only have excellent heat storage and heat preservation functions, It also has good adhesion, washing fastness and durability, thereby improving the application range of functional textile materials.

Description

technical field [0001] The invention relates to the field of far-infrared heat storage and heat preservation materials, in particular to a preparation method of water-based nano-microcapsule emulsion. Background technique [0002] In autumn and winter, keeping warm is an eternal theme. Thick, bloated, awkward and complicated, with three pieces inside and three pieces outside, is the portrayal of what people mainly wear in autumn and winter, so how to improve this situation? How about making people's clothes light, beautiful, comfortable and simple in autumn and winter? As a typical active thermal insulation material, far-infrared thermal storage textile materials can be blended with other fibers, which is an important development trend of textile and clothing in autumn and winter, and will inevitably become the mainstream of textile development in autumn and winter. [0003] The so-called far-infrared refers to electromagnetic waves with a wavelength ranging from 4 to 1000...
