Description
技术领域
本发明涉及合成革用表面处理剂领域,具体涉及一种合成革用无黄变高光油皮。本发明还涉及一种合成革用无黄变高光油皮的制备方法。
背景技术
合成革目前在各种领域都可替代真皮。合成革物理性好、耐曲折、柔软、抗拉伸强度大,且也有一定的透气性。合成革表面需用一些处理剂改善其表面色泽、光泽、手感。
合成革表面处理剂可以根据产品的类别进行表面涂饰,其可以改善合成革的亮度、色泽以及手感。然而,随着消费者对皮革表面的色泽和手感要求越来越高,不但要增加合成革的触感,还要保证合成革表面的亮度及色泽度等。而现有的表面处理剂已经不能满足消费者对合成革的亮度及手感日益增加的要求,因此急需一种既能提高合成革触感,又能提高合成革的手感,亮度、光泽等综合效果的处理剂。
发明内容
为了解决上述问题及缺陷,本发明的目的在于提供一种合成革用无黄变高光油皮。本发明还提供一种合成革用无黄变高光油皮的制备方法。
本发明的合成革用无黄变高光油皮通过以下技术方案实现:
一种合成革用无黄变高光油皮,其用于合成革的后段工艺,包含以下组分:1000分子量BG-AA二元醇、BDO、IPDI、DMF、反应型二甲基硅油和IPDA。
进一步地,所述1000分子量BG-AA二元醇与BDO的重量比为1∶0.06-0.5,所述1000分子量BG-AA二元醇与IPDI的重量比为1∶0.6-2,所述1000分子量BG-AA二元醇与DMF的重量比为1∶3.5-6.5,所述1000分子量BG-AA二元醇与反应型二甲基硅油的重量比为1∶0.03-0.1,所述1000分子量BG-AA二元醇与IPDA的重量比为1∶0.2-0.5。
本发明还提供一种合成革用无黄变高光油皮的制备方法,包含以下步骤:
(1)按重量配比称取各组分物质:将1000分子量BG-AA二元醇、BDO、IPDI、DMF、和反应型二甲基硅油混合,加热搅拌进行反应;
(2)当步骤(1)所得的混合物的异氰酸酯(-NCO)的百分含量小于0.3%时,加入DMF降温至室温;
(3)在步骤(2)所得的混合物中滴加IPDA,搅拌均匀,即得所述合成革用无黄变高光油皮。
进一步地,所述1000分子量BG-AA二元醇与BDO的重量比为1∶0.06-0.5。
进一步地,所述1000分子量BG-AA二元醇与IPDI的重量比为1∶0.6-2。
进一步地,所述1000分子量BG-AA二元醇与DMF的重量比为1∶3.5-6.5。
进一步地,所述1000分子量BG-AA二元醇与反应型二甲基硅油的重量比为1∶0.03-0.1。
进一步地,所述1000分子量BG-AA二元醇与IPDA的重量比为1∶0.2-0.5
进一步地,步骤(1)的反应温度为60℃-80℃。
进一步地,步骤(1)的反应时间为3-5小时。
由于采用以上技术方案,本发明与现有技术相比具有如下有益技术效果:
(1)本发明的合成革用无黄变高光油皮的各组分相互协调、共同作用,该合成革用无黄变高光油皮具有高光泽,手感滑爽,膜厚感强,有水晶透感的特点,且由于是脂肪族树脂,不会黄变,物性好;
(2)本发明的合成革用无黄变高光油皮是后段处理的一种新型材料,能够用于现有的合成革生产线,工艺简单,无需改变生产设备,不会增加生产成本;
(3)由于本发明的合成革用无黄变高光油皮具有无黄变的特点,因此其处理一版,烘干后涂膜量相当于普通光油皮处理的2-3版;
(4)本发明的合成革用无黄变高光油皮的流平性好,抗热回粘出色,且比普通高光光油更透。
