Description
技术领域
本发明涉及合成革技术领域,尤其涉及一种汽车内饰用石墨烯超细纤维合成革。
背景技术
汽车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。汽车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6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。电镜图显示贝斯的微观结构与天然皮革十分类似,同时也具有和天然皮革相类似的组织结构和超过天然皮革的理化性能。
汽车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,汽车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。
但普通汽车超纤皮革是采用涂层法来制备合成革,耐磨性不高,尤其是作为日系、德系和美系主机厂对于耐磨性要求较高,普通汽车超纤皮革很难稳定达到这一要求。基于现有技术存在的不足,本发明提出一种汽车内饰用石墨烯超细纤维合成革。

S3、制备粘合层浆料:将步骤S1称取的聚胺基甲酸酯树脂、二甲基甲酰胺和甲基乙基酮以300~500r/min的转速搅拌至全部溶解,提高转速至500~600r/min并将步骤S1称取的颜料加入,混合均匀得混合物B,然后将步骤S1称取的石墨烯分散乳液分散在混合物B中,即得粘合层浆料;
S4、超细纤维合成革的制备:将步骤S2制备的面层浆料均匀涂抹在离型纸上,并在进行烘干即得带有面层的离型纸,再通过干法合成革生产线将步骤S3制备的粘合层浆料喷涂在离型纸上面层的上面,并将基布压合到离型纸上,再烘干、熟化,将离型纸剥离即得汽车内饰用石墨烯超细纤维合成革。
