Description

一种高强度的EVA管材
技术领域
本发明涉及复合材料领域，具体地说是一种一种高强度的EVA管材。
背景技术
现有的EVA管材生产，消耗EVA树脂量较大，对企业成本有着较大的影响，因此，研究一种可以降低EVA树脂使用量，对EVA管材产量不产生影响的理想替代物，是时下研究的热点。EVA材料制备的管材因其具有重量轻、成本低和耐腐蚀性好的优点，被广泛使用，但其不足之处在于，低温情况下其韧性较差，随着温度降低，其抗冲击性越来越差，受冲击时极易破碎。
发明内容
针对现有技术的不足，本发明提供一种高强度的EVA管材。。
本发明的方案是通过这样实现的：
一种高强度的EVA管材，包括以下重量比的原料：EVA树脂70-90份、聚丙烯酸酯20-25份，稳定剂4-6份，发泡剂3-4份，防老剂3-5份。
优选的，该管材包括以下重量比的原料：EVA树脂80份、聚丙烯酸酯25份，稳定剂5份，发泡剂4份，防老剂3份
优选的，所述稳定剂为钙锌复合稳定剂。
优选的，所述发泡剂为ACR发泡剂。
优选的，所述防老剂为MB防老剂。
本发明具备以下良好效果：
（1）本发明的高强度EVA管材韧性高，伸长率大，常温抗冲强度、拉伸强度高。
（2）本发明的高强度EVA管材能够有效地防止EVA管材老化。
（3）本发明的高强度EVA管材材质更轻，耐压，耐冲击，隔音效果更好的。
（4）本发明的高强度EVA管材成本低廉、经济效益显著。
具体实施方式
以下结合实施例描述本发明的一种高强度的EVA管材，这些描述并不是对本发明内容作进一步的限定。
实施例1
一种高强度的EVA管材，包括以下重量比的原料：EVA树脂80份、聚丙烯酸酯25份，钙锌复合稳定剂5份，ACR发泡剂4份，MB防老剂3份。
