Abstract

The invention relates to a composite functional microcapsule for repelling mosquitoes and sunscreen and a preparation method thereof. The composite functional microcapsule includes a capsule wall loaded with an ultraviolet absorbing material and a capsule core wrapped in the capsule wall; wherein, the ultraviolet absorbing material is acid-analyzed lignin, The capsule core is a mixture of plant-based insect repellent and UV absorber. The invention can effectively utilize the synergistic effect between the lignin and the ultraviolet absorber, and can also achieve excellent ultraviolet protection function on the basis of realizing durable mosquito repellent. The composite functional microcapsule has important application value in the fields of summer clothing and daily cosmetics.

Description

technical field [0001] The invention belongs to the field of functional microcapsules, in particular to a composite functional microcapsule for repelling mosquitoes and sunscreen and a preparation method thereof. Background technique [0002] The advantages of microcapsule technology in the protection and controlled release of active substances (such as plant essential oils) have prompted it to be widely used in the textile field, such as mosquito repellent, fragrance, anti-ultraviolet and phase change microcapsules, etc. On this basis, a A series of functional textiles enhance the added value of traditional textiles. However, most of the existing microcapsules are single-functional microcapsules, and the preparation of multi-functional microcapsules is relatively rare. Taking pure cotton fabrics as an example, the acquisition of composite functions often requires the use of two or more functional finishing agents for composite finishing or multi-bath and multi-step process...
