Description
技术领域：
本发明涉及波纹管技术领域，特别涉及一种强度比较高的钢带波纹管。
技术背景：
钢带波纹管采用聚乙烯为外层的基本材料和弯曲成型的钢带通过挤塑复合而成，钢带波纹管将钢材的高钢度、高强度和塑料的耐腐蚀、耐磨损和柔韧性等优点合为一体，仅可使管材达到较高级别的环刚度，而且还解决了钢材的耐腐蚀问题，钢带增强聚乙烯螺旋波纹管的管道系统通常采用热熔挤出焊接及电熔带等方式连接，适应各种不同工程工况需要，较好地满足了密封可靠和连接方便的要求，管道应用前景广阔，是目前替代大口径传统排水管的首选产品。但是目前，市场上的钢带波纹管的内外层由单纯的PE材料制成，容易老化，且阻燃性比较低，耐变形性也比较低。
发明内容：
有鉴于此，有必要提供一种钢带波纹管。
一种钢带波纹管，包括内层、外层和增强钢带,将内层PE片材在芯轴上缠绕成实壁的芯管，形成钢带波纹管的内层，然后将预涂覆的增强钢带经过成型机和弯曲机形成V字形状，再在芯轴上按照预定螺距缠绕在芯管上，并挤出一层外层PE片材覆盖在增强钢带上形成外层，冷却后抽出芯轴，钢带波纹管成型；内层PE片材和外层PE片材的材料相同，包括以下原料及原料的重量份：
聚乙烯190份～210份，棚膜再生颗粒90份～110份，玻璃纤维18份～22份，干燥剂3份～7份。
优选的，内层PE片材和外层PE片材的较佳的原料的重量份为：聚乙烯200份、棚膜再生颗粒100份、玻璃纤维20份、干燥剂5份。
优选的，聚乙烯由高密度聚乙烯和线型低密度聚乙烯按照1:1的比例混合而成。
优选的，增强钢带外层涂覆防腐层和树脂粘接剂。
优选的，内层和外层与增强钢带成型前，对增强钢带进行油污的清洗处理。
优选的，内层和外层与增强钢带成型前，对增强钢带进行热处理工艺，并进行微氧化处理。
本发明提供的钢带波纹管，抗压力比较高，且增强钢带经过清洗处理和涂覆粘接剂的处理，使得内外层与增强钢带之间的粘接比较牢固，且内层和外层的原料的搭配和配比设计，使得内层和外层不易老化，所以，采用本发明大大提高了钢带波纹管的使用寿命。
