Description
技术领域
本发明涉及合成革材料技术领域,尤其涉及一种石墨烯超细纤维聚氨酯合成革及其制备方法。
背景技术
超纤皮革是新近发展起来的一种高档人工皮革,是在模仿天然皮革的结构、化学组织基础上发展起来的,超纤皮革是由束状超细纤维与聚氨酯经过特殊工艺加工而成,尼龙或涤纶超细纤维为三维立体骨架,聚氨酯在成品中呈不规则微细孔的立体网状结构,超纤皮革几乎具有天然皮革的一切特性和优点,并在断裂强度、撕裂强度、剥离强度、耐化学性能、吸排湿性、稳定性、保型性、自动化裁剪加工及后续加工适应性等方面更优于天然皮革,其密度小,在同等厚度的情况下,超纤皮的质量不到普通天然皮革质量的三分之二,可以大大节省材料的费用,但普通超纤皮革是采用离型纸转移涂层法来制备合成革,无论用在座椅沙发还是家装,也仅仅作为一个皮料使用。

优选的,所述耐光剂为TINUVIN 765或TINUVIN B75,所述耐磨剂为DC-53或DC-55。
本发明还提出了一种石墨烯超细纤维聚氨酯合成革的制备方法,包括以下步骤:
S1、按照比重称取各原料,备用;
S2、石墨烯的处理:首先将石墨烯溶解在纯水中,然后采用石墨烯研磨分散机对石墨烯采用机械分散,最后用超声波分散机对石墨烯进行再次分散,即得石墨烯分散液;
S3、将除石墨烯外的原料全部加入到搅拌机中,对原料进行充分搅拌,在搅拌的过程中慢慢加入石墨烯并搅拌20 min-40 min,当溶液搅拌彻底后,利用超声波分散器将溶液进行分散;
S4、将上述溶液利用过滤网过滤后,采用干法合成革生产线制备汽车超纤皮革。
优选的,所述石墨烯研磨分散机的搅拌速度为50-100转/分钟,搅拌时的温度为10℃-35 ℃,搅拌时间为25 min-35 min。
优选的,所述超声波分散机对石墨烯进行分散时的超声波频率为20 KHZ-30 KHZ,功率为1-5千瓦,超声波的分散时间为25 min-40 min,超声时的温度控制在10 ℃-60 ℃。
优选的,所述搅拌机中的搅拌速率为60-100转/分钟,所述过滤网的目数为100-200目。
优选的,所述超声波分散器的型号为GZ-1006,且分散的时间为30 min-40 min。
优选的,所述干法合成革生产线是以树脂用涂布法,涂布于各种纹路的离型纸上,经烘干、上糊后再用底布为基材一起贴合,烘干等制程,使产品的花纹与各种离型纸之纹路相同,再经印刷处理,使其在触感,韧性和外观上,足以媲美天然皮革。
本发明的有益效果是:
1、本发明,通过采用高科技手段制备的一款新型材料,经过高速搅拌后再用超声波超微分散等加工技术,能均匀分散到水性聚氨酯树脂中,与聚氨酯树脂成膜后,仍保持其本身的高导电高耐磨及催化性能。
