Description

一种塑胶防割防水手套的制备方法
技术领域
本发明属于高分子材料技术领域，具体涉及一种塑胶防割防水手套的制备方法。
背景技术
在工业加工生产领域以及应急救援工作中的作业人员在其工作中可能接触到摩擦、切割、穿刺等机械危害,为了减少或隔绝此类伤害,以上人员需要配置不同等级机械危害防护手套是，保护手或手臂免受摩擦、切割、穿刺中至少一种机械危害的手套，但是现有的防割手套使用金属丝和高性能聚乙烯纤维包覆纱织成，并没有有良好的弹性或舒适性，虽有一定强度的抗切割性能，但是穿戴并不舒适，而且使用范围、条件和环境受到限制，因为，其并不防水，在有水或其他液体环境下无法使用，在养殖水产、化工医疗等领域无法使用或者造成不必要的麻烦，例如在生化防护中，防护人员因病毒或化学试剂并不能得到有效防护而被感染或伤害，也有在防护过程中，现有的防割手套并不能满足现有的使用需求和性能需求。钢丝或玻璃纤维在使用中可能发生断裂，造成皮肤不适。 CN105411050A公开了一种防割手套，能够与针数无关地防止金属制或玻璃纤维制的线材突出， CN106987992A公开了一种添纱组织结构防割手套的制备方法，解决了在制造过程中存在的纱线容易缠结的问题，例如，修理带刺的花草时不宜使用防割手套。因为防割手套是由钢丝组合而成，会有许多密集小孔允许花刺透过，在修理花草时应使用正确的手套，以免受伤。此外，现有的防割手套，随纤维逐渐被抽拔伸出,再承受摩擦,这些纤维端会互相钩接、缠绕形成不规则球状的起球现象。随着使用中继续摩擦,纤维球逐渐紧密,并使连在手套上的纤维受到不同方向的反复折曲、疲劳以至断裂,纤维球便从织物表面脱落,会改变其表面的光泽、平整度、织纹和花纹,并浮起大量颗粒,严重影响手套的外观和手感。本领域技术人员亟待开发出一种塑胶防割防水手套的制备方法，以满足更高的市场需求和性能要求。
发明内容
本发明的目的是针对现有的问题，提供了一种塑胶防割防水手套的制备方法。
一种塑胶防割防水手套的制备方法，制备方法通过用碳纤维布浸涂橡塑共混物胶乳制成，其中按重量比，橡塑共混物胶乳占塑胶防割防水手套重量的50~55wt%，制备方法具体如下：（1）碳纤维布放入质量分数20%的硝酸水溶液中,煮沸保持5~10min后取出，用质量分数5%NaOH溶液中和碳纤维布表面的残留酸，再将预处理液涂覆到碳纤维布上，并超声处理20~35min，静置2~4h后在110℃下烘干，然后将碳纤维布放入高温炉中，并使高温炉在400~500℃的温度下保持2~4h，然后使碳纤维布随炉冷却至室温，将碳纤维布编织拼合成手套形状，得活化碳纤维布；（2）在重量份数计100份聚氨酯基体浆液中添加1~2份对的固化剂，使其形成固体含量为30~41%的胶液，将步骤（1）得到的活化碳纤维布浸于该胶液中2~4h，然后将碳纤维布取出并在75~85℃下烘干，制得预浸布手套，备用；（3）将预浸布手套依次经过剪裁、卷丝、缠带紧压、60℃加热活化0.5h和脱模处理，得到毛坯，将毛坯经剪裁、除去线头和整理，制成塑胶防割防水手套胚体；（4）在20~25℃条件下，使丁腈橡胶胶乳的氯醋树脂乳液混配成分混配，在混配过程中控制总固体含量在48~52％、pH值在7.3~7.8，得到橡塑共混物胶乳，橡塑共混物胶乳经过匀浆陈化后，再将制成塑胶防割防水手套胚体在陈化后的橡塑共混物胶乳中进行内外浸渍，浸渍后将所述手套模具取出并在100~105℃条件下烘干，以在所述手套模具上形成依附胶膜，得覆胶胚体；（5）将步骤（4）所述覆胶胚体上形成的胶膜进行常规卷边、烘干、膨润、脱膜、脱水处理后，再在105~115℃条件下干燥硫化1~2h，以形成手套，即得。
进一步的方案，在步骤（4）中，橡塑共混物胶乳匀浆陈化1~2天。
进一步的方案，在步骤（4）中，浸渍过程在30~45℃条件下进行。
进一步的方案，在步骤（4）中，所述内外浸渍重复浸渍2~3次。
进一步的方案，在步骤（2）中，所述烘干的时间为5~15分钟。
进一步的方案，在步骤（1）中，所述预处理液为由重量份数计的，无水硫酸铜25~30份、硼氢化钠6~8份、正辛醇1~2份、酒石酸钾钠4~6份、水200份组成。
进一步的方案，所述步骤（2）的固化剂为苯酮四羧酸二酐，聚氨酯基体浆液为水性聚氨酯酯基体浆液。
本发明的有益效果：
本发明公开的一种塑胶防割防水手套的制备方法，本发明通过共混改性和复合改性的有机结合,同时由于聚氨酯的加入,又具备摩擦系数小、较好的电性能以及较高的弹性回复能力和耐腐蚀性能。由于和活化处理碳纤维布以及预处理液和碳纤维形成化学键和螯合物,在分子内和分子间形成交联,因此在热处理过程中防止了分子碎片的逸散,使手套的强度得到了提高,也使热处理时间显著缩短，其中中的无机元素，可以提高手套的阻燃性和强度，进一步改善相容性,从而显著提高手套本体强度、韧性，而且能改进聚合物对被碳纤维的湿润性和界面结合,良好的两相界面结合有利于传递和分散应力,从而提高手套强度，本申请采用内外浸渍，进一步保证手套的防割性能，且使手套具有防水性。
本发明相比现有技术具有以下优点：本发明公开的一种塑胶防割防水手套的制备方法，本发明通过共混改性和复合改性的有机结合，制备的塑胶防割防水手套有优良的防切割性能、富有弹性、穿戴适应性好、易于关节弯曲、透气性好、脱戴方便， 有优良的防切割性能、富有弹性、穿戴适应性好、穿着时伸缩自如，弹性舒适合体，有很强的市场竞争力，能够提供最大程度的防护，即使不采用玻璃纤维或钢丝增强，也能够达到高防割等级防护，纤维手感清凉，比芳纶手套散热更快，因此能够保持手部凉爽干燥，即使反复穿戴、洗涤和使用也不会降低性能，可抵挡循环磨擦切割4级8000次的破坏。

1.一种塑胶防割防水手套的制备方法，其特征在于，制备方法包括用碳纤维布浸涂橡塑共混物胶乳制成，其中按重量比，橡塑共混物胶乳占塑胶防割防水手套重量的50~55wt%，制备方法如下：（1）将碳纤维布放入质量分数20%的硝酸水溶液中,煮沸保持5~10min后取出，用质量分数5%NaOH溶液中和碳纤维布表面的残留酸，再将预处理液涂覆到碳纤维布上，并超声处理20~35min，静置2~4h后在110℃下烘干，然后将碳纤维布放入高温炉中，并使高温炉在400~500℃的温度下保持2~4h，然后使碳纤维布随炉冷却至室温，将碳纤维布编织拼合成手套形状，得活化碳纤维布；（2）在重量份数计100份聚氨酯基体浆液中添加1~2份对的固化剂，使其形成固体含量为30~41%的胶液，将步骤（1）得到的活化碳纤维布浸于该胶液中2~4h，然后将碳纤维布取出并在75~85℃下烘干，制得预浸布手套，备用；（3）将预浸布手套依次经过剪裁、卷丝、缠带紧压、60℃加热活化0.5h和脱模处理，得到毛坯，将毛坯经剪裁、除去线头和整理，制成塑胶防割防水手套胚体；（4）在20~25℃条件下，使丁腈橡胶胶乳的氯醋树脂乳液混配成分混配，在混配过程中控制总固体含量在48~52％、pH值在7.3~7.8，得到橡塑共混物胶乳，橡塑共混物胶乳经过匀浆陈化后，再将制成塑胶防割防水手套胚体在陈化后的橡塑共混物胶乳中进行内外浸渍，浸渍后将所述手套模具取出并在100~105℃条件下烘干，以在所述手套模具上形成依附胶膜，得覆胶胚体；（5）将步骤（4）所述覆胶胚体上形成的胶膜进行常规卷边、烘干、膨润、脱膜、脱水处理后，再在105~115℃条件下干燥硫化1~2h，以形成手套，即得。
2.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，在步骤（4）中，橡塑共混物胶乳匀浆陈化1~2天。
3.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，在步骤（4）中，浸渍过程在30~45℃条件下进行。
4.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，在步骤（4）中，所述内外浸渍重复浸渍2~3次。
5.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，在步骤（2）中，所述烘干的时间为5~15分钟。
6.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，在步骤（1）中，所述预处理液为由重量份数计的，无水硫酸铜25~30份、硼氢化钠6~8份、正辛醇1~2份、酒石酸钾钠4~6份、水200份组成。
7.如权利要求1所述的一种塑胶防割防水手套的制备方法，其特征在于，所述步骤（2）的固化剂为苯酮四羧酸二酐，聚氨酯基体浆液为水性聚氨酯酯基体浆液。
