Description
本申请是申请号为201610745628.3、申请日为2016年08月29日、发明名称为“用废旧含铬皮屑制作静电植绒用粉末状绒毛的方法”的分案申请。
技术领域
本发明属于皮革技术领域，具体涉及一种用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法。
背景技术
我国是制革大国，每年产生上百万吨的皮革废弃物，其中有一半左右为含铬皮屑。早期的含铬皮屑主要采用传统的废弃物处理方式：填埋或焚烧，给环境带来了极大的危害。随着环保意识的逐渐加强，传统的处理方式已逐渐被淘汰，人们逐渐采取回收再利用的方式对含铬皮屑进行处理，不仅可以减少对环境造成的危害，还可以节约成本。
目前，含铬皮屑的回收利用方式主要分为脱铬回收和不脱铬回收。不脱铬回收一般是将含铬皮屑回用于制革工业；脱铬回收其方法一般是将含铬皮屑用酸水分解为适当分子量的含铬胶原多肽后直接用于皮革填充，因此有大量有关用含铬皮屑制备皮革用填充剂的相关报道。而脱铬回收方法较为复杂，其生产成本仍较高，而若采用不脱铬回收的方式再利用含铬皮屑，生产的皮革产品无真皮感，手感粗糙，其质量有待进一步改善。
静电植绒是利用高压静电电场，将绒毛植到各种基布的表面，一般在基布表面会有一层植绒胶黏剂，因此绒毛会被粘附于基布表面，待胶黏剂固化后，即得静电植绒产品。而目前未见有直接利用废旧含铬皮屑制作静电植绒用粉末状绒毛的相关报道。
发明内容
本发明的目的是为了解决现有技术的不足，而提供一种用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，用该方法制得的静电植绒用粉末状绒毛手感细腻爽滑，并可赋予静电植绒产品良好的真皮感。
本发明采用如下技术方案：
用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，包括如下步骤：
步骤一：将废旧含铬皮屑粉碎至颗粒状，并干燥至含水量48%-55%，得颗粒料；
步骤二：将步骤一所得颗粒料烘干至含水量20%-30%，得烘干料；
步骤三：将步骤二所得烘干料静置95-105天，过筛筛选，得筛选料；
步骤四：将步骤三所得筛选料浸入有机溶剂中，按筛选料质量计，加入0.05%-0.1%手感剂，搅拌30-40min，排液，得一次处理料；
步骤五：将步骤四所得一次处理料置于缸中，按照步骤三所得筛选料质量计，加入1%-2%脱脂剂，运行20-30min，加入1.5%-2%渗透剂运行20-30min，加入1%-2%碳酸氢钠、4%-4.5%甲酸钠及0.5%-0.8%柠檬酸钠，运行25-30min，加入2%-3%染料，加入1.2%-1.7%固色剂，运行25-35min，再加入1.5%-2.5%染料，升温至50-55℃，运行25-35min，加入1%-2%固色剂，运行8-12min，加入7%-8%加脂剂，运行40-50min，加入4.5%-5.5%氯化钠，运行5-15min，加入0.8%-1.2%爽滑剂，运行40-50min，出缸，脱水至含水量50%-60%，继续烘干至含水量15%-20%，即得所述静电植绒用粉末状绒毛。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，其中步骤一中所述颗粒过100目筛。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，将步骤二所得烘干料于20-26℃、相对湿度60%-70%下静置95-105天。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，其中步骤三中所述过筛为过100目筛筛选。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，其中步骤四中所述有机溶剂为乙醇、乙酸乙酯或丙酮中的一种。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，其中步骤四中所述手感剂为弱阳离子型水性手感剂。
更进一步的，所述的用废旧含铬皮屑制作具有细腻爽滑手感的静电植绒用粉末状绒毛的方法，其中步骤五中所述脱脂剂为非离子表面活性剂类脱脂剂；所述渗透剂为脂肪醇聚氧乙烯醚；所述加脂剂为磺化天然油脂，所述爽滑剂为溶剂型皮革爽滑剂。
本发明与现有技术相比，其有益效果为：
本发明利用废旧含铬皮屑制作静电植绒用粉末状绒毛，制得的粉末状绒毛手感细腻爽滑，将该粉末状绒毛采用静电植绒方法植入在基布表面，具有优异的仿皮效果和良好的真皮感，且绒面手感细腻，柔软平滑。此外，本发明合理利用了废旧含铬皮屑，绿色环保，且方法简便易行，可大范围推广应用。
在本发明方法中，烘干料经过长时间自然放置后，可以使粉碎料进一步干燥，但是干燥后皮屑会不规则卷曲，导致某些皮屑颗粒体积过大，故需要进一步过筛筛选；步骤四中手感剂的加入使皮屑具有柔软绵滑感，可确保最终的静电植绒粉末状绒毛的手感，使其爽滑细腻，而有机溶剂可促使手感剂更好的渗入皮屑表面；步骤五的再处理进一步增强了皮屑的手感和真皮感，爽滑剂的使用可以使制得的粉末状绒毛具有平滑干爽的效果。
具体实施方式
下面结合实施例对本发明作进一步的详细描述。
本领域技术人员将会理解，下列实施例仅用于说明本发明，而不应视为限定本发明的范围。本发明中使用的手感剂为弱阳离子型水性手感剂，型号为HK-16，购自嘉兴宏麟皮化有限公司；所述脱脂剂为非离子表面活性剂类脱脂剂，型号为borron DN，购自德瑞皮革科技（青岛）有限公司；所述加脂剂为磺化天然油脂，其为深棕色，可通过购买获得；所述爽滑剂为溶剂型皮革爽滑剂，型号为HK-15，购自嘉兴宏麟皮化有限公司。
