Description

一种超微玻纤棉增强HDPE双壁波纹管材成型方法
技术领域
本发明涉及建材技术领域,具体涉及一种超微玻纤棉增强HDPE双壁波纹管材成型方法。
背景技术
超微玻纤棉增强母粒主要应用于化纤产品(地毯、涤纶、无纺布等),吹膜制品(包装袋、流延膜、多层复合膜等),吹塑制品(医药和化妆品容器、油漆容器等),挤塑制品(片材、管材、电缆、电线等),注塑制品(汽车配件、电器、建材、日用品、玩具、体育用品等)。其具有使用方便,对成型环境无污染,着色均匀、稳定,提高塑料制件质量、易于计量、可应用自动化程度高的成型生产系统,可将着色、抗老化剂、抗静电剂等集于一方制成多功能母粒,方便使用等优点。
HDPE是世界5大常用塑料之一,鉴于其良好的韧性及加工性,得到广泛使用,在市政给排水管道中也得以大量运用,常规HDPE双壁波纹管材一般采用滑石粉和碳酸钙作为增强材料,相比玻纤存在强度低、重量大、尺寸收缩明显等缺点,导致管材环刚度低、抗外压能力差、成本高等问题。
但现有的技术中,HDPE双壁波纹管材的成型方法成型效果差,成型后的HDPE双壁波纹管材环刚度、强度、环柔性和冲击性能等指标达不到合格要求。
