Description

一种抑制聚氯乙烯革增塑剂迁移的方法
技术领域
本发明涉及抑制聚氯乙烯革增塑剂迁移技术领域,具体领域为一种抑制聚氯乙烯革增塑剂迁移的方法。
背景技术
聚氯乙烯软质人造革,具有动物皮的质感,同时具有耐刮、耐磨、耐酸、耐碱、防水、强度好、使用寿命长等优异的性能,一部分按摩椅目前采用PU革做面料,由于PU革耐候性差,使用寿命短,表面易老化、脱皮,而聚氯乙烯革耐刮、耐磨、柔软度均与PU革相似,且使用寿命是PU革2倍以上,价格又低于PU革,因此PU革按摩椅面料将逐渐被聚氯乙烯革所取代,但聚氯乙烯革要达到一定的柔软程度,必须大量的加入低分子增塑剂,低分子量的增塑剂容易受温度、压力及接触介质的影响而迁移到革面,如按摩椅在使用时,由于按摩椅球的运动及按压,将会对按摩椅面料产生持续的作用力,增加了革内的增塑剂分子运动,容易使增塑剂分子扩散到表面,造成革面发粘、污染、革变硬而导致使用性能下降;广告装饰行业中常采用聚氯乙烯膜革喷绘,但同样存在增塑剂易析出而导致喷绘画面不清晰,色彩饱和度和光泽度受到影响,且油墨易脱落的情况,因此为解决聚氯乙烯革中增塑剂易迁移析出的问题,提出一种抑制聚氯乙烯革增塑剂迁移的方法。
发明内容
本发明的目的在于提供一种抑制聚氯乙烯革增塑剂迁移的方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种抑制聚氯乙烯革增塑剂迁移的方法,聚氯乙烯革包括发泡层、面层和基布层,其特征在于:包括以下步骤:
(1)发泡层制备
A、将聚氯乙烯树脂投入到高速搅拌机中进行搅拌,同时逐渐升温,当温度升高到60℃时,加入增塑剂TOTM和PPA,继续进行搅拌,当温度升高至105~115℃时,加入淀粉、纳米钙、稳定剂粉体钡锌、整泡剂、发泡剂AC粉、加工助剂丙烯酸和着色剂,搅拌均匀得到弹性混合料;
B、使用密炼机对步骤A中制备的弹性混合料进行混炼,混炼温度为150~160℃,得到聚氯乙烯块状料;
C、使用二辊开炼机对步骤B中制备的聚氯乙烯块状料进行进一步混炼塑化,二辊开炼机温度为155℃,辊距0.4cm,得到塑化聚氯乙烯块状料;
D、使用过滤机对步骤C中制备的塑化聚氯乙烯块状料进行过滤,去除杂质颗粒,过滤机身温度为150℃,过滤机头温度为140℃,过滤机转速控制在28~35r/min,得到净化聚氯乙烯块状料;
E、使用L型2030四辊压延机对步骤D中制备的净化聚氯乙烯块状料进行压延,侧辊温度195℃、上辊温度180℃、中辊温度175℃,下辊170℃;侧辊线速度18m/min、上辊线速度24m/min、中辊线速度28m/min、下辊线速度30m/min,得到发泡层;
(2)面层制备
A、将聚氯乙烯树脂投入到高速搅拌机中进行搅拌,同时逐渐升温,当温度升高到60℃时,加入增塑剂TOTM和PPA,继续进行搅拌,当温度升高至105~115℃时,加入淀粉、纳米钙、稳定剂粉体钡锌和着色剂,搅拌均匀得到弹性混合料;
B、使用密炼机对步骤A中制备的弹性混合料进行混炼,混炼温度为150~160℃,得到聚氯乙烯块状料;
C、使用二辊开炼机对步骤B中制备的聚氯乙烯块状料进行进一步混炼塑化,二辊开炼机温度为155℃,辊距0.4cm,得到塑化聚氯乙烯块状料;
D、使用过滤机对步骤C中制备的塑化聚氯乙烯块状料进行过滤,去除杂质颗粒,过滤机身温度为150℃,过滤机头温度为140℃,过滤机转速控制在28~35r/min,得到净化聚氯乙烯块状料;
E、使用L型2030四辊压延机对步骤D中制备的净化聚氯乙烯块状料进行压延,侧辊温度195℃、上辊温度180℃、中辊温度175℃,下辊170℃;侧辊线速度18m/min、上辊线速度24m/min、中辊线速度28m/min、下辊线速度30m/min,得到面层;
(3)聚氯乙烯革制备
采用贴合机将基布层贴合到发泡层的一侧,再将面层贴合到发泡层的另一侧。
优选的,所述聚氯乙烯树脂型号为DH.3000,出自杭州点化集团有限公司。
优选的,所述基布层采用化纤仿麂皮绒,规格为180g/㎡。
本发明的有益效果是:
1、主材料:主材料采用高聚合度的聚氯乙烯树脂(DH.3000,杭州点化集团有限公司),由于分子量的较大,分子链团的结晶组成有较大提高,使无规则分子链之间的缠绕点增多,对增塑剂分子链缠结作用较大,增塑剂不易从聚氯乙烯树脂中迁移出来。
2、增塑剂:增塑剂作用是调节聚氯乙烯革软硬度,加入量越多产品越柔软,弹性越好,但易迁移到产品表面,本发明选用增塑效率高、难迁移、与聚氯乙烯树脂相容性好,且环保的增塑剂偏苯三酸三辛酯(TOTM)和已二酸丙二醇酯(PPA);
TOTM作为聚氯乙烯树脂主增塑剂,与现有技术中常用的邻苯二甲酸二辛酯(DOP)相比,耐热、耐寒、难挥发、抗抽出、环保、热损失率低,PPA是高分子增塑剂,能有效抑制增塑剂向产品表面迁移抽出。
3、淀粉:淀粉是天然高分子材料,与增塑剂有良好的结合能力及可塑性,淀粉大分子链段排列堆砌而成三维网络结构,分子链的缠绕限制增塑剂分子链的运动,起到阻挡增塑剂迁移的作用。
4、纳米钙:可延缓增塑剂的挥发,当纳米粒径1mm时,表面原子数比例达到90%以上,原子几乎全部集中到纳米粒子的表面,限制增塑剂分子链的运动,起到阻挡作用。
5、稳定剂:发泡层用粉体钡锌,加工时润滑性好,同时可使面层具有良好的抗氧化、抗紫外线、耐寒性能。
6、整泡剂:整泡剂为现有技术,在发泡层中可使泡孔稳定。
7、发泡剂:偶氮二甲酰胺(AC),发泡后,可使聚氯乙烯革具有动物皮质感。
8、着色剂:采用色饼,使聚氯乙烯革表面色着鲜艳。
9、加工助剂丙烯酸:提高聚氯乙烯革强度,降低聚氯乙烯树脂塑化温度,增加聚氯乙烯混料的黏着力。
10、基布层:采用化纤仿麂皮绒,规格为180g/㎡,其性能不亚于天然麂皮,织物毛感柔软,有糯性,悬垂性好。
