本发明属于织物涂层制备领域，具体涉及了一种基于相变微胶囊的智能调温纺织品的涂层整理技术。The invention belongs to the field of fabric coating preparation, and particularly relates to a coating finishing technology for intelligent temperature-regulating textiles based on phase-change microcapsules.
背景技术Background technique
相变材料(PCMs)是一类能够储能蓄热，高效利用热量的材料。相变材料的种类繁多，其中固-液型相变材料由于相变过程的可控性强和可多次循环利用，应用最为广泛，这种材料在相变过程中总是要经历物态的变化，例如固态和液态的相转变，在转变过程中会发生体积的变化、易熔融泄露等问题，在很大程度上限制了应用。Phase change materials (PCMs) are a class of materials that can store heat and utilize heat efficiently. There are many types of phase change materials, among which solid-liquid phase change materials are the most widely used due to their strong controllability and recyclability of the phase change process. Changes, such as the phase transition between solid state and liquid state, have problems such as volume change and easy melting and leakage during the transition process, which limit the application to a large extent.
相变材料微胶囊化能有效的解决相变材料易熔融泄露等问题，即选择合适的壁材，对相变材料进行包覆制备成相变微胶囊(MEPCMs)，这种做法极大的提高了相变材料的利用率同时也拓宽了其应用范围。例如，Sara等人首次采用sol-gel法，研究了以PA(棕榈酸)为芯材，SiO2为壁材的纳米相变微胶囊的制备，制备的SiO2/PA纳米微胶囊具有良好的热性能、化学稳定性和较高的热导率；Tivadar采用石蜡和十六醇相变材料为载体，三甲氧基(甲基)硅烷为水解液，采用sol-gel法制备了二氧化硅包覆微球，这类相变微胶囊显示出相对较高的潜热储存能力；Chen等人采用sol-gel法制备了以SiO2为壁材的复合储能微胶囊化硬脂酸(SA)，防止了熔融硬脂酸的泄漏。Microencapsulation of phase change materials can effectively solve the problems of easy melting and leakage of phase change materials, that is, selecting appropriate wall materials and coating the phase change materials to prepare phase change microcapsules (MEPCMs), which greatly improves the The utilization rate of phase change materials is also broadened. For example, Sara et al. used the sol-gel method for the first time to study the preparation of nano-phase change microcapsules with PA (palmitic acid) as the core material and SiO2 as the wall material. The prepared SiO2 /PA nano-microcapsules have good Thermal performance, chemical stability and high thermal conductivity; Tivadar uses paraffin and cetyl alcohol phase change material as the carrier, trimethoxy (methyl) silane as the hydrolyzate, and the sol-gel method is used to prepare the silica package Coated microspheres, this type of phase change microcapsules showed relatively high latent heat storage capacity; Chen et al. prepared the composite energy storage microencapsulated stearic acid (SA) withSiO2 as the wall material by the sol-gel method, The leakage of molten stearic acid is prevented.
相变微胶囊制备技术的发展，为功能纺织品行业提供了一个新的方向，即利用相变微胶囊制备能实现智能调温的蓄热调温纺织品。蓄热调温纺织品的工作原理是附着在织物表面或填充到纤维内部的相变材料在遇冷或受热后会发生物态转变，从而释放或吸收热量，实现温度变化动态平衡的效果，起到调温的作用。The development of phase change microcapsule preparation technology provides a new direction for the functional textile industry, that is, the use of phase change microcapsules to prepare thermal storage and temperature regulation textiles that can realize intelligent temperature regulation. The working principle of thermal storage and temperature-adjusting textiles is that the phase change material attached to the surface of the fabric or filled into the fiber will undergo a physical state transformation after being cooled or heated, thereby releasing or absorbing heat, realizing the effect of dynamic balance of temperature change, and playing a role in The role of temperature regulation.
目前相变微胶囊主要通过纺丝和后整理两种方式应用到织物上。例如，Li等采用丙烯酸系共聚壁材对正十八烷进行微胶囊化，并对所得微胶囊进行高温高压处理，采用湿法纺丝法制备了含有微胶囊的海藻酸纤维；胡春华等对服饰用相变调温纺织品进行研究，探究了用于低温条件下蓄热调温纺织品的相变材料复配比和面料性能对相变效果的影响，得出正十六烷和正十八烷这两种相变材料的最佳复配比为0.2:0.8；钱惺悦等以石蜡为芯材制备微胶囊，并将微胶囊配成整理液，采取浸轧方式将其应用到涤纶和纯棉织物上。At present, phase change microcapsules are mainly applied to fabrics by spinning and finishing. For example, Li et al. used acrylic copolymer wall material to microencapsulate n-octadecane, and the obtained microcapsules were treated with high temperature and high pressure, and alginate fibers containing microcapsules were prepared by wet spinning method; Hu Chunhua et al. The phase-change temperature-adjusting textiles were used for research, and the effect of the phase-change material compound ratio and fabric properties on the phase-change effect of the heat-storage and temperature-adjusting textiles under low temperature conditions was investigated, and it was concluded that n-hexadecane and n-octadecane The optimal compounding ratio of these phase change materials is 0.2:0.8; Qian Xingyue et al. prepared microcapsules with paraffin as the core material, formulated the microcapsules into a finishing solution, and applied them to polyester and cotton fabrics by padding. superior.
中国发明专利CN00105837《自动调温纤维及其制品》，提供了一种以三聚氰胺、环氧树脂、脲醛树脂或硅酸钙为囊壁，采用原位聚合法合成微胶囊，但目前以脲醛树脂等聚合物做壁材，都无法解决甲醛残留的问题，故而限制了其应用。The Chinese invention patent CN00105837 "Automatic Thermoregulating Fiber and Its Products" provides a kind of microcapsules with melamine, epoxy resin, urea-formaldehyde resin or calcium silicate as the capsule wall, and the in-situ polymerization method is used to synthesize microcapsules. Polymers used as wall materials cannot solve the problem of formaldehyde residues, which limits its application.
中国发明专利CN200710057493《一种智能调温纺织品及其制备》，提供了一种以醇类相变材料为芯材，以二氧化硅凝胶为壳材，在二氧化硅的吸附作用下制取微胶囊。但此种微胶囊通常只适合做蓄热涂料，而不适用于制备蓄热调温纺织品。Chinese invention patent CN200710057493 "An intelligent temperature-adjusting textile and its preparation" provides a kind of alcohol phase change material as the core material and silica gel as the shell material, prepared under the adsorption of silica Microcapsules. However, such microcapsules are usually only suitable for thermal storage coatings, not for the preparation of thermal storage and temperature-regulating textiles.
中国发明专利CN102733192《一种纳米相变微胶囊蓄热调温智能纺织品织物印染布的整理工艺》提供了一种将微胶囊配成整理液，在交联剂的作用下通过浸轧，整理到纺织上。但在整理过程中可能出现微胶囊破裂，芯材泄露的情况。Chinese invention patent CN102733192 "A Finishing Process of Nanometer Phase Change Microcapsule Heat Storage and Temperature Adjusting Intelligent Textile Fabric Printing and Dyeing Cloth" provides a method of preparing microcapsules into a finishing solution, and by padding under the action of a crosslinking agent, finishing to textile. However, during the finishing process, the microcapsules may rupture and the core material leaks.
虽然目前已有大量专家学者对该领域进行了研究，但相变微胶囊在纺织品上的应用还存在着诸多问题，例如石蜡等芯材导热系数低，价格较高，使用的壁材会阻碍热量传递，且对芯材的包覆率较低，导致调温性能不明显。更重要的是，经过整理后，织物上含有的微胶囊较少，微胶囊与纤维或织物的结合率较低。Although a large number of experts and scholars have carried out research in this field, there are still many problems in the application of phase change microcapsules in textiles. For example, core materials such as paraffin have low thermal conductivity and high prices, and the wall materials used will hinder heat. transfer, and the covering rate of the core material is low, resulting in insignificant temperature regulation performance. What's more, after finishing, the fabric contains less microcapsules, and the microcapsules are less bound to the fiber or fabric.
有鉴于此，本发明在经过一系列的实验和研究的基础上，总结出了一种基于相变微胶囊的智能调温纺织品的涂层整理技术方案。In view of this, on the basis of a series of experiments and researches, the present invention summarizes a technical solution for coating finishing of intelligent temperature-regulating textiles based on phase-change microcapsules.
