技术领域
本发明涉及导电泡棉材料及其构造技术领域,尤其涉及拓扑式导电泡棉材料及其构造方法。
背景技术
导电泡棉是一种导电的电磁屏蔽材料,是在阻燃海绵芯上缠绕导电编制套制成,具有良好的抗腐蚀性和抗氧化性,导电泡棉还具有表面导电性、电磁屏蔽性、质量轻、韧性好、弹性佳、厚度可压缩、阻燃、可冲切成各种形状、环境适应力强等优点,被广泛应用于消费电子、家电、通讯、医疗器械、工控、军工、航空航天等行业中,发展前景巨大。
但是现有的导电泡棉的连接方式单一,大部分都是单独应用于设备的某一个部分,无法形成一个应用网络,对于导电泡棉的性能应用效果未达到最佳,因此,我们提出了拓扑式导电泡棉材料及其构造方法用于解决上述问题。
发明内容
本发明目的是为了解决现有的导电泡棉的连接方式单一,大部分都是单独应用于设备的某一个部分,无法形成一个应用网络,对于导电泡棉的性能应用效果未达到最佳的问题,而提出的拓扑式导电泡棉材料及其构造方法。
为了实现上述目的,本发明采用了如下技术方案:
拓扑式导电泡棉材料,包括以下重量份的原料:聚乙烯90-100份、碳黑40-60份、导电布30-50份、聚乙烯呲啶4-12份、氯化聚乙烯3-15份、发泡剂3-8份、敏化剂0.5-3份、抗氧化剂0.5-6份、三聚氰胺0.3-4份、三聚氰胺氰尿酸盐0.3-4份、氮0.5-3份、磷0.5-3份、热熔胶5-20份、聚烯烃复合胶20-40份;
优选的,包括以下重量份的原料:聚乙烯95-100份、碳黑50-60份、导电布40-50份、聚乙烯呲啶6-10份、氯化聚乙烯3-12份、发泡剂4-8份、敏化剂0.5-2.5份、抗氧化剂1-6份、三聚氰胺0.3-3份、三聚氰胺氰尿酸盐0.3-3份、氮0.6-2份、磷0.6-2份、热熔胶8-15份、聚烯烃复合胶20-30份;
优选的,包括以下重量份的原料:聚乙烯98份、碳黑55份、导电布50份、聚乙烯呲啶8份、氯化聚乙烯6份、发泡剂8份、敏化剂2.5份、抗氧化剂4份、三聚氰胺2份、三聚氰胺氰尿酸盐2份、氮1.5份、磷1.5份、热熔胶10份、聚烯烃复合胶30份。
