Description

一种高韧性耐磨的周转箱板材
技术领域
本发明涉及塑料技术领域，具体涉及一种高韧性耐磨的周转箱板材。
背景技术
PP是一种半结晶的热塑性塑料。由于其具有较高的耐冲击性，机械性质强韧，抗多种有机溶剂和酸碱腐蚀的优良性能，被广泛地应用于物流周转箱中。由于物流周转箱在使用过程中需要频繁的上料、下料、转移等操作，造成周转箱容易开裂、磨损。应用常规的PP板材，无法解决上述问题。
发明内容
针对以上问题，本发明提供一种高韧性耐磨的周转箱板材，能够解决常规的周转箱板材出现的开裂、磨损问题。
为实现上述目的，本发明通过以下技术方案来解决：
一种高韧性耐磨的周转箱板材，包括周转箱板材，所述周转箱板材包括以下重量份的组分：PP 100份、PMMA 5～15份、PTFE 1～5份、碳化硅晶须0.2～0.7份、活化纳米二氧化钛0.1～0.5份、TCEP 0.1～0.3份、发泡剂0.5～1.5份。
具体的，所述活化纳米二氧化钛由以下步骤制作而成：取纳米二氧化钛，加入偶联剂搅拌均匀，再升温至80℃后保持20min，得到活化纳米二氧化钛。
具体的，所述纳米二氧化钛的粒径为10～100nm。
具体的，所述偶联剂选自钛酸酯偶联剂、硅烷偶联剂中的一种。
具体的，所述发泡剂选自碳酸钙、碳酸镁、碳酸氢钠中的一种。
本发明的有益效果是：
1.本发明的高韧性耐磨的周转箱板材，将PP、PMMA、PTFE共混后制成周转箱板材，具有高韧性、耐磨性良好的特点，能够解决常规的周转箱板材出现的开裂、磨损问题；
2.加入了碳化硅晶须，碳化硅晶须具有高强度、抗高温、增韧的特点，能够改良板材的强度、耐热性以及韧性；
3.加入了活化纳米二氧化钛，活化纳米二氧化钛由纳米二氧化钛经过活化后制得，作为紫外线屏蔽剂，防止周转箱板材受到紫外线的侵害，以提升周转箱板材的抗老化能力；
4.加入了TCEP，提升了周转箱板材的阻燃性能。
具体实施方式
为了能进一步了解本发明的特征、技术手段以及所达到的具体目的、功能，下面结合具体实施方式对本发明作进一步的详细描述。
实施例1

第三步：将第二步中称取好的PP、PMMA、PTFE、碳化硅晶须、活化纳米二氧化钛、TCEP、碳酸氢钠加入螺杆挤出机中混合均匀以及塑化，温度设置为185-195℃；
第四步：将第三步中得到的混合物通入模具压力型腔中，加压至10-20MPa并保压5-10min，降压发泡，降压发泡时间为2-8分钟，温度为195-205℃，得到发泡板材；
第五步：将上述得到的发泡板材经过辊筒辊压成型，冷却至常温后得到周转箱板材，周转箱板材厚度为5mm。
测试：
对上述得到的周转箱板材进行性能测试，测试结果记录如下表1。
对比例1
