Embodiment approach

[0028] A preparation method of antibacterial phase change energy storage microcapsules, comprising the following steps,

[0029] S1. Mix 1,3,5-benzenetricarboxylic acid chloride, phase-change energy storage material and emulsifier and heat it to become a liquid. Add deionized water at the same temperature under high-speed stirring to form an emulsion. The emulsifier is a combination of OP-10 and sodium dodecylbenzenesulfonate; the high-speed stirring speed is 800-2000rpm.

[0030] S2. Add a tertiary amine-containing polyamino compound to the emulsion obtained in step S1, stir for 0.5 to 3 hours, separate and wash with water to obtain tertiary amine-modified microcapsules; the tertiary amine-containing polyamino compound molecule contains at least one primary amino group, At least one secondary amino group and at least one tertiary amino group or at least two primary amino groups and at least one tertiary amino group in the molecule;

[0031] S3. Disperse the tertiary amine-mo...

Embodiment 1

[0042] Mix 0.5 parts of 1,3,5-benzenetricarboxylic acid chloride, 10 parts of n-docosane, 0.4 parts of OP-10 and 0.1 parts of sodium dodecylbenzenesulfonate, heat to 52°C to become a liquid, and stir at 1000-1100rpm Add 12 parts of deionized water at the same temperature under rotating speed to form an emulsion.

[0043] Add 0.23 parts of N,N-dimethyldipropylenetriamine to the obtained emulsion, stir for 3 hours, separate and wash with water to obtain tertiary amine-modified microcapsules;

[0044] Disperse 1 part of the obtained tertiary amine-modified microcapsules in 50 parts of tetrahydrofuran, add 0.01 part of epichlorohydrin, raise the temperature to 45°C, stir for 8 hours, cool down, separate, wash, and dry to obtain antibacterial phase change energy storage microcapsules. Capsules, denoted as E-1, have an average particle size of 3.5 μm.

Embodiment 2

Abstract

The invention belongs to the field of synthetic fibers, and particularly relates to a preparation method of an antibacterial phase-change energy-storage microcapsule, and a fiber. 1, 3, 5-benzoyl chloride and a phase-change energy-storage material are emulsified into an emulsion, the emulsion and a tertiary amine-containing polyamino compound are subjected to a cross-linking reaction to obtain a microcapsule containing tertiary amino functional groups on the surface, and the microcapsule reacts with a halogen-containing quaternization reagent to obtain the quaternized phase change energy storage microcapsule with better antibacterial performance. The antibacterial phase change energy storage microcapsule is applied to fibers, and the obtained fiber has good antibacterial and washable properties.

Description

technical field [0001] The invention belongs to the field of synthetic fibers and relates to a preparation method of antibacterial phase change energy storage microcapsules and fibers. Background technique [0002] In today's society, energy is becoming more and more tense, and the awareness of energy saving is also increasing. Phase-change energy storage microcapsules are micron-sized materials whose outer shell is cross-linked polymer and inner core contains phase-change energy storage materials. It can be applied in Among the fibers, the woven and formed fabric has the effect of cooling when the temperature is high and keeping warm when the temperature is low. A number of technologies have reported the preparation methods of phase change energy storage microcapsules. [0003] All kinds of bacteria and viruses are ubiquitous in life, which greatly affects human health. Effective antibacterial fabrics are becoming more and more popular, and there are many public reports o...
