Description
技术领域
本发明属于装饰材料领域,具体涉及一种多功能复合装饰材料。
背景技术
随着人们生活水平的进一步提升,人们对于建筑、家具的装修要求也在不断提升,不仅要求相关装饰材料具有风格多变、色彩多样、图案丰富、视觉美观、装饰效果良好等特点,还要求具有防火防水、耐磨耐刮、安全环保、施工方便、易于更换等特性,这就对传统的墙纸、墙布、饰面板等企业提出了更高的要求。
随着我国墙纸、墙布、饰面板等产业的日臻成熟,以及人们安全环保意识的加强,人们关注墙纸、墙布、饰面板色彩与风格多样性的同时,也更加关注产品的实用及安全环保等性能。具有各色风格图案的各类耐刮擦、易清洁、耐老化、耐高温、防火、防水、除甲醛、除臭等功能的新型墙纸、墙布、饰面板,开始走俏市场。相关产品主要通过在纸基、布基或者木材表层涂布、粘合、热熔或复合一层或多层功能涂层,来达到相应的阻燃、易清洗、保温、耐刮擦、防水等功能,这方面的中国专利有CN103074815、CN206127727、CN102776805、CN103485504、CN100526554、CN107060235、CN206530006、CN107326749、CN206085878、CN107143105、CN107053382、CN108032592等。通过这些方法制备的功能性墙纸、墙布或饰面板,均存在一个重要的问题,就是其墙纸、墙布或饰面板的功能性较为单一,不够全能。
因此,提供一种功能齐全的墙面复合装饰材料具有极大的高端市场需求。
发明内容
本发明的目的是提供一种多功能复合装饰材料。
为实现上述发明目的,本发明所采用的技术方案是:一种复合装饰材料,所述复合装饰材料包括4层结构,从内到外依次为:无纺布层、PVC糊树脂层、压延材料层和超薄碳纳米管涂层。
优选的,所述无纺布层由玻璃纤维和聚酰亚胺纤维混合制成。
优选的,所述复合装饰材料的配方为,按重量份数,玻璃纤维25~100份、聚酰亚胺纤维25~200份、PVC糊树脂50~600份、压延材料1~200份、超薄碳纳米管涂层材料0.1~1.2份。
优选的,所述复合装饰材料的配方为,按重量份数,玻璃纤维50份、聚酰亚胺纤维98份、PVC糊树脂100份、压延材料50份、超薄碳纳米管涂层材料0.3份。
优选的,所述无纺布层的制作方式为:以合计为2~6根的玻璃纤维与聚酰亚胺纤维为一组、混合编织形成纤维束,将所述纤维束梳理成网、加固即得。
优选的,所述无纺布层的制作方式为:以1根玻璃纤维和2根聚酰亚胺纤维为一组,按三股麻花辫式进行编织形成纤维束,将所述纤维束梳理成网、加固即得。
优选的,所述玻璃纤维与聚酰亚胺纤维进行加韧后,再进行编织;
所述加韧的方式为:按重量份数,将2~10份碳纳米管加入100份乙醇或氯仿中,超声分散均匀,即得纤维增韧剂;将玻璃纤维、聚酰亚胺纤维分别没入纤维增韧剂中,浸泡过夜,随后将各纤维小心地取出,真空环境下,从室温缓慢升温到80~90℃,保温烘干,升温速度控制在0.5~0.8℃/min,即得加韧后的玻璃纤维与聚酰亚胺纤维。
优选的,所述PVC糊树脂的配方为:30~35wt%邻苯二甲酸二辛酯、0.5wt%纳米氮化硼、1~3wt%纳米金红石型钛白粉或Ti3+/TiO2、2~4wt%微米硫酸钡、38~48wt%糊树脂P450、10~20wt%聚酰亚胺粉末、0~7wt%微球发泡剂、2wt%钡锌类热稳定剂。
优选的,所述PVC糊树脂的制备方法为:常温常压下,在反应釜内加入邻苯二甲酸二辛酯、纳米氮化硼、纳米金红石型钛白粉或Ti3+/TiO2、微米硫酸钡,于12000r/min分散5min,再加入糊树脂P450、聚酰亚胺粉末、微球发泡剂、钡锌类热稳定剂;
混匀后,按下列步骤依次进行三次分散:2000r/min分散5min,6000r/min分散2min,3000r/min分散30min;分散结束后,再在24~48h内,于2500r/min分散15min,即得PVC糊树脂。
优选的,所述Ti3+/TiO2的制备方法为:将TiCl4完全溶于无水乙醇中,超声10min,再加入质量为TiCl4质量40%的单质锌,搅拌反应30min,再加入质量为TiCl4质量1~1.5倍的TiF3,超声10min,随后在150℃下保温20~14h;冷却、干燥,即得所需的Ti3+/TiO2。
本发明具有以下有益效果:
1、本发明创造性地使用了4层结构,提供了一种视觉美观、方便印刷、安全无毒、高强度、耐刮擦、可擦洗、抗老化、防火、防水、防霉、抗裂、施工方便、装饰效果良好的墙面复合装饰材料。
2、复合装饰材料的基层材料为无纺布,编织无纺布时,长丝纤维易破碎、表面光滑、纤维无卷曲,成网性能差、不易加固,所以难以直接用于制作无纺布。一般都是先将长丝切成短丝纤维,再梳理成网,然后针刺加固。但这样就丧失了长丝纤维的特性,且容易损失纤维。本发明创造性地先用碳纳米管对玻璃纤维和聚酰亚胺纤维进行加韧,避免纤维在编织过程中破碎;随后再使用增韧后的纤维以1根玻璃纤维和2根聚酰亚胺纤维为一组,按三股麻花辫的方式进行编织;再将编织后的纤维束梳理成网,针刺加固后生成无纺布。
这种制备无纺布的方式克服了玻璃纤维本身性脆易折的缺陷,保留了长丝纤维本身的特性,兼具玻璃纤维和聚酰胺亚胺纤维共同的优点,安全无毒、力学性能优异,耐刮擦、耐老化、防火防水、透气性和韧性优异、尺寸稳定,适用范围广,并具有自洁能力。
3、为了使无纺布材料具有更优越的加工性能,更适宜于印刷等,本发明还在无纺布上涂覆了一层PVC糊树脂。但PVC糊树脂不防火,需要额外添加阻燃剂。传统的阻燃剂多为卤系阻燃剂(以氯系、溴系为代表),具有一定毒性,不适于家装等要求高的领域。而无机阻燃剂(如氢氧化铝、氢氧化镁等)或反应型阻燃剂(MCA、TBP等)等,要不就是遇火后的分解产物有毒;要不就是阻燃剂会缓慢自分解,逐渐失去阻燃效果;或者就是阻燃剂添加量小了阻燃效果差、添加量大了会严重影响PVC糊树脂的性能,均不理想。
本发明创造性的以聚酰亚胺粉末为阻燃剂,无毒无害、性能稳定,还可进一步提高复合材料的耐磨、耐热、耐老化、抗辐射等性能。聚酰亚胺粉末本身的氧指数高达48,添加到本发明所用的PVC糊树脂中后,所制备的PVC糊树脂氧指数高达27以上,属于难燃级别。
4、本发明还提供了一种制备Ti3+/TiO2并添加到PVC糊树脂中的方法。TiO2本身具有去除甲醛的能力;同时,其被光激发出的带负电的电子具有较强的杀菌作用,可以赋予材料杀菌、自洁的能力。但普通的TiO2因其禁带宽度较大,只有在紫外光激发下才能产生带负电的电子,而Ti3+可以在TiO2的导带底引入局域态,从而使TiO2可被可见光甚至红外光激发出带负电的电子。
TiF3中的F-改变了TiO2的形貌,使其内部溶解并向外扩散,形成空壳TiO2,在高温过程中,TiO2晶格中的氧原子脱离,形成氧空位,吸引TiF3中的Ti3+并包裹到空心结构内部,或吸附在TiO2表面,形成Ti3+/TiO2,使复合装饰材料在日常使用中,普通光照环境下,即可具有除甲醛、杀菌、自洁的能力。
5、本发明在PVC糊树脂的外层压合了一层PVC压延皮或PU压延皮,可以根据需要对其进行击凸、压纹等工艺,从而赋予复合装饰材料裸眼3D的视觉效果。
PVC压延皮或PU压延皮本身不防火,且无法直接添加阻燃材料,所以本发明还创造性地在压延皮表面喷涂了一层超薄(厚度0.5~1.5μm)的碳纳米管涂层材料,以增加耐磨、防火防水、耐腐蚀等性能。
具体实施方式
一、本发明的配方。
1、本发明的总配方为:按重量份数,玻璃纤维25~100份、聚酰亚胺纤维25~200份、PVC糊树脂50~600份、压延材料1~200份、超薄碳纳米管涂层材料0.1~1.2份。
2、所述配方中,除PVC糊树脂外的优选方案如下:

(2)所述聚酰亚胺纤维为醚类均聚型聚酰亚胺纤维,其拉伸强度>3cN/dtex,模量>9GPa。更优选的方案为:所述聚酰亚胺纤维为P84型聚酰亚胺粉末,由芳香族二胺与芳香族二酐合成。

所述碳纳米管涂层材料,优选为羟基化多壁碳纳米管/氟碳乳液;所述羟基化多壁碳纳米管的管径为10~20nm,长度0.1~1.0μm,纯度>98%,羟基含量为2.8~3.2%。
3、所述PVC糊树脂的配方为:
30~35wt%邻苯二甲酸二辛酯(增塑剂,以下简称DOP)、0.5wt%纳米氮化硼、1~3wt%纳米金红石型钛白粉或Ti3+/TiO2、2~4wt%微米硫酸钡、38~48wt%糊树脂P450、10~20wt%聚酰亚胺粉末、0~7wt%微球发泡剂、2wt%钡锌类热稳定剂。
二、本发明的具体操作步骤。
1、制备无纺布。
(1)制备纤维增韧剂:按重量份数,将2~10份碳纳米管加入100份乙醇或氯仿中,超声分散均匀,即得纤维增韧剂。
(2)将玻璃纤维、聚酰亚胺纤维分别加入纤维增韧剂中,浸泡过夜,随后将各纤维小心地取出,真空环境下,从室温缓慢升温到80~90℃,保温烘干,升温速度控制在0.5~0.8℃/min。
(3)将增韧后的各纤维混合编织成束,优选为以1根玻璃纤维、2根聚酰亚胺纤维为一组,按三股麻花辫的方式编织成束。
(4)采用无纺布成型工艺,将纤维束梳理成网、针刺加固,即得所需无纺布。
也可不进行纤维加韧的步骤,直接将各纤维编织后再制备无纺布,只是无纺布的综合性能会有所下降。
2、制备PVC糊树脂。
(1)制备Ti3+/TiO2:将TiCl4完全溶于无水乙醇中,超声10min,再加入质量为TiCl4质量40%的单质锌,搅拌反应30min,再加入质量为TiCl4质量1~1.5倍的TiF3,超声10min,随后在密封环境下、150℃保温20~14h。自然冷却后,先用无水乙醇冲洗沉淀物1~2次,再用去离子水冲洗沉淀物1~2次,随后干燥,即得所需的Ti3+/TiO2。对产物进行透射电镜和扫描透射电镜观察,发现生产的TiO2内部出现空心结构。
(2)制备PVC糊树脂:在常温常压下,往不锈钢搅拌釜内加入DOP、纳米氮化硼、纳米金红石型钛白粉或Ti3+/TiO2、微米硫酸钡,于12000r/min分散5min,再加入糊树脂P450、聚酰亚胺粉末、微球发泡剂(本发明使用的为购于日本松本油脂制药株式会社,型号为微球发泡剂F-50,使用其它中低温膨胀型微球发泡剂也可)、钡锌类热稳定剂。
按下列步骤依次进行三次分散:2000r/min分散5min,6000r/min分散2min,3000r/min分散30min。分散结束后,再在24~48h内,于2500r/min分散15min,即得PVC糊树脂。
如果不使用Ti3+/TiO2,直接使用钛白粉,也可以达到发明目的,只是制备的PVC糊树脂的杀菌、自洁能力相应下降。
3、制备复合装饰材料。
PVC糊树脂均匀涂到所述无纺布表面,干燥后,根据需要将压延材料压合在PVC糊树脂表面,具体压合工艺为现有技术,可以使用压合机等实现,在此不再赘述。压合结束、干燥固化成型后,再在表面喷涂碳纳米管,通过在物体表面喷涂及快速固化工艺形成的一层覆膜涂层,涂层厚度为0.5~1.5μm。干燥后根据需要进行印花、击凸、压纹等工艺,即得所需的复合装饰材料。
下面结合具体实施例对本发明进行进一步解释。
实施例一:不同纤维处理方式的效果展示
1、按上述配方和操作步骤制备11组复合装饰材料。其余条件相同,不进行增韧处理和编织处理,作为对照组。
各组中玻璃纤维和聚酰亚胺纤维的重量份数、处理方式、无纺布制备方式,如表1所示。其中,纤维束未进行编织,指直接将玻璃纤维和聚酰亚胺纤维混合后梳理成网制备无纺布。纤维束编织方式中,用“玻”/“玻纤”代替玻璃纤维,用“聚”/“聚纤”代替聚酰亚胺纤维,“玻”和“聚”前面的数字分别指一束纤维束中,玻璃纤维、聚酰亚胺纤维分别的数量;如1玻2聚指1根玻璃纤维与2根聚酰亚胺纤维为一组。1玻多聚是指按各纤维重量份数称取纤维后,按玻璃纤维和聚酰亚胺纤维各自实际的数量进行比例划分,根据划分情况再进行编织;比如,称取特定重量份数的两种纤维后,该重量份数中含有玻璃纤维有10根,聚酰亚胺纤维有30根,则以1根玻璃纤维与3根聚酰亚胺纤维为一组进行麻花辫式编织。按特定编织方式进行编织后,最后多余的长丝纤维按该特定编织方式进行自行编织;比如,按1玻1聚的方式编织后,最后剩余10根聚酰亚胺纤维,没有多余的玻璃纤维与其匹配,则这10根聚酰亚胺纤维以2根为一组进行相互缠绕形成纤维束。
表1各组纤维处理方式列表
