Description
技术领域technical field
本发明属于纺织品整理剂技术领域，具体涉及一种纺织品用无卤阻燃自修复超疏水涂层胶及阻燃自修复超疏水织物。The invention belongs to the technical field of textile finishing agents, and in particular relates to a halogen-free flame-retardant self-repairing superhydrophobic coating adhesive for textiles and a flame-retardant self-repairing superhydrophobic fabric.
背景技术Background technique
织物在人们的生活中随处可见。但由于其易燃的特性，近些年来由于织物燃烧造成的人身伤亡和财产损失也愈来愈多。因此，对织物进行阻燃处理势在必行。相比于我国，欧美较早就开始了对阻燃织物的研究。我国阻燃织物的研发生产始于20世纪60年代。时至今日，我国阻燃织物的研发及生产虽然取得了长足的进展，但仍然无法满足日益增长的需求。如今，使用阻燃涂层胶对织物进行阻燃处理是最为常用的一种制备阻燃织物的方法。但是，现有的阻燃涂层胶存在一些缺点，其中之一就是涂层胶的稳定性欠佳。由于阻燃涂层胶易溶或易分解的特点，对阻燃织物进行水洗清洁后，织物的阻燃性会急剧的降低甚至丧失。因此，如何以低成本的方式制备具有良好稳定性的阻燃涂层胶仍然是一个挑战。Fabrics can be seen everywhere in people's lives. However, due to its flammable characteristics, in recent years, more and more personal casualties and property losses have been caused by fabric burning. Therefore, it is imperative to carry out flame-retardant treatment on fabrics. Compared with my country, Europe and the United States started research on flame-retardant fabrics earlier. The development and production of flame-retardant fabrics in my country began in the 1960s. Today, although the research and development and production of flame-retardant fabrics in my country have made great progress, they still cannot meet the growing demand. Nowadays, the flame-retardant treatment of fabrics with flame-retardant coating glue is the most commonly used method for preparing flame-retardant fabrics. However, there are some disadvantages in the existing flame-retardant coating adhesives, one of which is the poor stability of the coating adhesives. Due to the characteristics of the flame retardant coating glue being soluble or easy to decompose, after washing and cleaning the flame retardant fabric, the flame retardancy of the fabric will be sharply reduced or even lost. Therefore, how to prepare flame-retardant coating adhesives with good stability in a low-cost manner is still a challenge.
近些年，随着仿生学和纳米科学的发展，人们对超疏水材料的研究愈发透彻。类似于荷叶、水禽类的羽毛等，人造超疏水材料具有极强的疏水能力。水滴在超疏水材料上接触角大于150°，滚动角小于10°。因此，超疏水材料在防腐蚀、自清洁领域有广泛的应用前景。将超疏水功能引入到阻燃涂层胶中，可以得到具有超强防水能力和自清洁性能的新型阻燃织物。由于超疏水功能带来的自清洁性，阻燃超疏水织物不需要长时间的浸泡洗涤，只需要用少量水冲洗即可除去织物表面的灰尘和污渍，大大的减少了涂层胶与水接触的时间和面积，因此可以有效地提高阻燃织物的使用寿命。此外，近期自修复超疏水材料的研发受到了广泛关注。在受到紫外线照射、化学腐蚀或划伤后，自修复超疏水材料能够自发的对受损的功能进行修复，从而有效地提高材料的使用寿命。因此，阻燃自修复超疏水涂层胶的制备具有重要的科研和经济意义。然而这方面的研究却少之又少。通过文献检索，仅有一篇期刊文献报道了制备阻燃自修复超疏水织物的方法(参见ACS Nano 2015,9,4070–4076)。但该方法具有一定的缺陷：(1)该方法过于复杂。为了实现阻燃超疏水织物的制备，需要对织物进行多次修饰处理，耗费大量的时间与能源，且很难与现有的生产设备相兼容。(2)该方法使用的材料具有含氟的物质，价格昂贵且对环境和使用者的健康具有潜在的危害。In recent years, with the development of bionics and nanoscience, research on superhydrophobic materials has become more and more thorough. Similar to lotus leaves, feathers of waterfowl, etc., artificial superhydrophobic materials have extremely strong hydrophobicity. The contact angle of water droplets on superhydrophobic materials is greater than 150°, and the rolling angle is less than 10°. Therefore, superhydrophobic materials have broad application prospects in the fields of anti-corrosion and self-cleaning. Introducing the superhydrophobic function into the flame-retardant coating adhesive can obtain a new type of flame-retardant fabric with super waterproof ability and self-cleaning performance. Due to the self-cleaning property brought by the super-hydrophobic function, the flame-retardant super-hydrophobic fabric does not need to be soaked and washed for a long time. It only needs to be rinsed with a small amount of water to remove the dust and stains on the surface of the fabric, which greatly reduces the contact between the coating glue and water. Time and area, so it can effectively improve the service life of flame-retardant fabrics. In addition, the development of self-healing superhydrophobic materials has received extensive attention recently. After being exposed to ultraviolet rays, chemical corrosion or scratches, self-healing superhydrophobic materials can spontaneously repair the damaged functions, thereby effectively improving the service life of the materials. Therefore, the preparation of flame-retardant self-healing superhydrophobic coating adhesive has important scientific and economic significance. However, there are very few studies in this area. Through literature search, only one journal article reported the method of preparing flame-retardant self-healing superhydrophobic fabric (see ACS Nano 2015, 9, 4070–4076). But this method has certain defects: (1) This method is too complicated. In order to realize the preparation of flame-retardant superhydrophobic fabrics, it is necessary to modify the fabrics multiple times, which consumes a lot of time and energy, and is difficult to be compatible with existing production equipment. (2) The materials used in this method have fluorine-containing substances, which are expensive and potentially harmful to the environment and the health of users.

一种阻燃自修复超疏水织物，是将织物(纯棉、涤纶等)浸入到前面所述的纺织品用无卤阻燃自修复超疏水涂层胶溶液中5～30分钟后，取出晾干后得到，该阻燃自修复超疏水织物具有良好阻燃性能和自修复超疏水性能。A flame-retardant self-repairing super-hydrophobic fabric, which is to immerse the fabric (pure cotton, polyester, etc.) in the aforementioned non-halogen flame-retardant self-repairing super-hydrophobic coating glue solution for textiles for 5 to 30 minutes, then take it out and dry it in the air Finally, the flame-retardant self-healing superhydrophobic fabric has good flame-retardant properties and self-healing superhydrophobic properties.
使用本发明制备的织物具有良好的阻燃效果，火源撤离后织物自行熄灭，为织物的大规模使用提供了安全、可靠的保证。超疏水性能赋予织物良好的防水性，水滴在其表面的接触角大于150°，滚动角小于10°，可以有效的保护阻燃剂。超疏水性在受到紫外线、化学腐蚀后，在30～90℃下保持0.5～8个小时，疏水剂会扩散到受损的区域，使织物的疏水性恢复到受损前的状态。这样的修复破坏可以重复10次以上，从而有效地延长阻燃自修复超疏水织物的使用寿命。此外，本发明不限于为易燃织物提供阻燃自修复超疏水功能，也可以通过调节配方组成，去掉无卤阻燃剂，涂敷在已经具有阻燃功能的织物上为其提供持久的自修复超疏水功能。本发明制备的阻燃自修复超疏水涂层胶制备工艺过程简单，所使用的阻燃剂、疏水剂均不含卤素，环保无毒可广泛应用于床上用品，家居装饰等，符合发展新材料的要求，具有广阔的市场应用前景。The fabric prepared by using the invention has good flame-retardant effect, and the fabric will extinguish itself after the fire source is removed, which provides a safe and reliable guarantee for the large-scale use of the fabric. The superhydrophobic property endows the fabric with good water resistance. The contact angle of water droplets on its surface is greater than 150°, and the rolling angle is less than 10°, which can effectively protect the flame retardant. After the superhydrophobicity is subjected to ultraviolet rays and chemical corrosion, keep it at 30-90°C for 0.5-8 hours, and the hydrophobic agent will diffuse to the damaged area, so that the hydrophobicity of the fabric will return to the state before the damage. Such repair damage can be repeated more than 10 times, thereby effectively prolonging the service life of the flame-retardant self-healing superhydrophobic fabric.

按照以上配方，依次向250mL的烧杯中加入100mL四氢呋喃，2.0g聚磷酸胺(APP)，1.0g氧化锌纳米粒子，1.0g聚丙烯酸酯乳液，0.2g石蜡，充分搅拌至均匀，配制成混合分散液，即得到本发明所述的无卤阻燃自修复超疏水涂层胶。将纯棉织物浸泡于上述混合分散液5min，取出，悬挂自然晾干，即可得阻燃自修复超疏水织物。According to the above formula, add 100mL tetrahydrofuran, 2.0g polyphosphate amine (APP), 1.0g zinc oxide nanoparticles, 1.0g polyacrylate emulsion, 0.2g paraffin into a 250mL beaker in turn, stir until uniform, and prepare a mixed dispersion Liquid, namely obtain the halogen-free flame-retardant self-healing superhydrophobic coating adhesive of the present invention. Soak the pure cotton fabric in the above mixed dispersion for 5 minutes, take it out, hang it to dry naturally, and you can get the flame-retardant self-healing super-hydrophobic fabric.
通过以上方法所制备的阻燃自修复超疏水织物，水滴在其上接触角达到158°，滚动角小于5°，具有良好的超疏水性质(图1a)。在受到200瓦的氧等离子体刻蚀5分钟后，织物的超疏水性受到破坏，接触角变为0°(图1b)。将受损的织物加热到80℃保持30min，即可使接触角恢复到158°(图1c)，实现超疏水性的自修复。这一受损/修复过程可以重复10次以上。同时该织物具有良好的阻燃效果。当火源移开后(图2a)，织物立即熄灭，过火长度小于4cm(图2b)。作为对比，未经修饰的织物在火源移开后继续燃烧直至全部烧尽。The flame-retardant self-healing superhydrophobic fabric prepared by the above method has a water drop contact angle of 158° and a rolling angle of less than 5°, showing good superhydrophobic properties (Figure 1a). After being etched by 200 W oxygen plasma for 5 min, the superhydrophobicity of the fabric was destroyed and the contact angle became 0° (Fig. 1b). Heating the damaged fabric to 80°C for 30 min restored the contact angle to 158° (Fig. 1c), realizing superhydrophobic self-healing. This damage/repair process can be repeated more than 10 times. At the same time, the fabric has a good flame-retardant effect. When the fire source was removed (Fig. 2a), the fabric was extinguished immediately, and the burnt length was less than 4cm (Fig. 2b). As a comparison, the unmodified fabric continued to burn until completely burned after the source of the fire was removed.
