Description

一种鞋里革的制备方法
技术领域
本发明属于合成革技术领域，具体涉及一种鞋里革的制备方法。
背景技术
随着人们生活水平的提高，环保产品得到更多的关注，传统民用油性鞋里革逐渐凸显出弊端，因为其在生产的过程中会伴随着DMF，吸附在皮革里，隐藏性地可能对人体产生伤害。
为了环保要求，鞋里革的面层及底层材料也逐渐被水性聚氨酯材料替代油性材料，如中国专利CN107090723A公开的一种生产环保型水刺无纺布鞋里革的方法，包括以下步骤：第一步：将45g至80g的水刺无纺布在水性聚氨酯和水性色浆的混合液中浸渍；第二步：再经轧干、烘干：第三步然后通过离型纸法与水性聚氨酯面层，无溶剂发泡聚氨酯底层复合，得到所需的各种颜色和花纹的水刺布鞋里革。所述物料配比30％水性聚氨酯体积比100份，水100份，色浆若干。然而该鞋里革的生产时，干法底层与贝斯贴合后再熟化，制得鞋里革，虽然环保上有一定的提高，但鞋里革的剥离强度、耐折和耐磨性等性能都还存在不足。
发明内容
本发明目的是为了克服现有技术的不足而提供一种鞋里革的制备方法。
为达到上述目的，本发明所采用的技术方案为：
一种鞋里革的制备方法，所述制备方法包括以下步骤：
(1)使70～100份第一水性PU树脂、0.1～0.5份水性增稠剂、0.2～0.5份流平剂和水混合搅拌均匀制得第一混合浆料，脱泡，然后将所述第一混合浆料涂覆在离型纸表面，烘干，制得PU面层；
(2)使70～100份第二水性PU树脂、0.1～0.5份水性增稠剂、0.2～0.5份流平剂和水混合搅拌均匀制得第二混合浆料，脱泡，将所述第二混合浆料涂覆在步骤(1)制得的PU面层的表面，烘干，在所述PU面层上形成PU底层，制得PU干膜；
(3)将基布用水性湿法树脂含浸后，烘干，制得贝斯；
(4)将无溶剂粘合剂涂覆在步骤(2)制得PU干膜的PU底层上，预烘干，然后与步骤(3)制得的所述贝斯贴合，烘干熟化，制得所述鞋里革；
其中，步骤(4)中，所述无溶剂粘合剂的原料配方包括：90～110份聚醚型多元醇、0.2～0.8份凝胶催化剂、0.05～0.15份发泡催化剂、40～60份钙粉和100～120份异氰酸酯预聚体。
在进一步的实施方式中，步骤(4)中，所述聚醚型多元醇为聚醚型多元醇300C-A，所述凝胶催化剂为催化剂SA-8，所述发泡催化剂为催化剂93600，所述异氰酸酯预聚体为异氰酸酯预聚体300C-B。
在进一步的实施方式中，步骤(4)中，所述无溶剂粘合剂的湿涂层厚度为0.2±0.05mm。
在进一步的实施方式中，步骤(4)中，所述预烘干采用的温度为120～140℃，时间为0.5～1.5min；所述烘干熟化采用的温度为125～145℃，时间为10～20min。
在进一步的实施方式中，步骤(1)中，所述第一水性PU树脂为聚碳脂肪族水性PU树脂，具体为水性PU树脂13926和水性PU树脂299的混合物按质量比2～3：1，所述流平剂为硅类流平剂。
在进一步的实施方式中，步骤(1)中，所述水的加入量使所述混合浆料的粘度控制在2800±200CPS。
在进一步的实施方式中，步骤(1)中，涂覆在离型纸上的湿涂层厚度控制在0.10±0.05mm。
在进一步的实施方式中，步骤(1)中，所述烘干采用的温度70～90℃，时间为10～20min。
在进一步的实施方式中，步骤(2)中，所述第二水性PU树脂为聚碳脂肪族水性PU树脂，具体为水性PU树脂846HY，所述流平剂为硅类流平剂。
在进一步的实施方式中，步骤(2)中，所述水的加入量使所述混合浆料的粘度控制在2800±200CPS。
在进一步的实施方式中，步骤(2)中，涂覆在PU面层上的湿涂层控制在0.13±0.05mm。
在进一步的实施方式中，步骤(3)中，所述水性湿法树脂为水性湿法树脂HG-001。
在进一步的实施方式中，步骤(3)中，所述烘干在60～120℃温度下阶梯式升温烘干。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
本发明鞋里革采用特定的无溶剂粘合剂将PU干膜与贝斯复合，并通过优化无溶剂粘合剂的配方，选取合适的原材料制备PU底层和PU面层，使得鞋里革的剥离强度得到大大的提高，同时鞋里革的耐折性、耐磨性都得到改善，且通过检测本发明的鞋里革的DMF含量，其含量低于5ppm，满足ZDHC组织要求对鞋里革DMF含量的要求。而且通过使用该无溶剂粘合剂还丰富了鞋里革的手感，及增加鞋里革的厚度。
本发明鞋里革使用的无溶剂粘合剂中通过加入特定催化剂，并通过优化催化剂的比例，以调整粘合剂的发泡倍率和凝胶状态，根据化学反应原理我们可以知道无溶剂体系反应的关键在于-NCO和-OH两种基团的比例关系，-OH含量多，所得到的无溶剂手感偏软，发泡倍率高，增加胺类催化剂可以提高发泡效率，但同时也要适当增加凝胶催化剂的比例，从而得到质地均匀的发泡体；而-NCO含量多，无溶剂手感偏硬，发泡倍率小，减少胺类催化剂的比例，提高凝胶催化剂比例，控制反应体的稳定性。
具体实施方式
下面结合具体实施例对本发明的具体实施作进一步详细说明，但本发明的实施和保护范围不限于此。
实施例1
本实施例提供的鞋里革，其通过以下方法制备得到：
(1)将第一水性PU树脂、去离子水、水性增稠剂和流平剂混合搅拌均匀制得第一混合浆料，并将混合浆料的粘度控制在2800±200CPS，搅拌过程中产生气泡，静置脱泡，取一有纹路的离型纸DE90，用10丝涂布棒将第一混合浆料刮涂在离型纸的表面，湿料涂层厚度为0.10mm，放入80℃烘箱静置15min，制得PU面层；
(2)将第一水性PU树脂、去离子水、水性增稠剂和流平剂混合搅拌均匀制得第二混合浆料，并将第二混合浆料的粘度控制在2800±200CPS，搅拌过程中产生气泡，静置脱泡，然后用13丝涂布棒将第二混合浆料刮涂至步骤(1)制得的PU面层的表面，湿料涂层厚度为0.13mm，同样放入80℃烘箱静置15min，在PU面层形成PU底层，制得具有面层和底层的PU干膜；
(3)将基布用水性湿法树脂HG001含浸后，依次经过60℃/80℃/100℃/120℃温区烘干，制得贝斯；
(4)将聚醚型多元醇、凝胶催化剂、发泡催化剂、钙粉混合搅拌1min，然后加入110份异氰酸酯预聚体加入到上述混合体系中，继续搅拌30s，制得无溶剂粘合剂，用25丝涂布棒将无溶剂粘合剂刮涂在步骤(2)制得的PU干膜的底层表面，无溶剂粘合剂的湿涂层厚度为0.2mm，放入130℃烘箱，密闭烘50s，待用手指触碰无溶剂表面有拉丝的现象时，将步骤(3)制备的贝斯贴合无溶剂粘合涂层上，然后放入135℃烘箱静置15min熟化，制得鞋里革。
本例中，面层、底层和无溶剂粘合剂的具体原料配方如表1所示。
对比例1
本例中提供的鞋里革，与实施例1不同之处在于：不使用无溶剂粘合剂，具体如下，将步骤(2)的涂覆有第二混合浆料的PU面层和离型纸复合膜，放置烘箱烘至半干，然后与步骤(3)制得的贝斯贴合，然后放入135℃烘箱静置15min熟化，制得鞋里革。
结果发现，直接将PU膜与贝斯复合，不仅仅会影响成品革的整体质感，会降低表面纹路的紧致感，无法给予鞋里革丰富的肉感。
对比例2
本例中提供的鞋里革，与实施例1的不同之处在于：无溶剂粘合剂的配方中不添加发泡催化剂。其他同实施例1。
对比例3
本例中提供的鞋里革，与实施例1的不同之处在于：无溶剂粘合剂的配方中不添加凝胶催化剂。其他同实施例1。
