Abstract

一种抗震抗压的玻璃钢复合管，由玻璃钢内层、蜂窝板芯层和玻璃钢外层复合构成，其中蜂窝板芯层由蜂窝板绕制构成，蜂窝板中的蜂窝孔沿复合管的径向设置。本发明将蜂窝板复合在玻璃钢管的管壁中，蜂窝板层两侧的玻纤干布可以使得适量的树脂胶渗入填充在蜂窝孔内，但又能阻挡过多的树脂胶渗入填充在蜂窝孔内。蜂窝板在厚度方向上强度很高，复合在玻璃钢管的管壁中不会降低玻璃钢管管壁的强度，而蜂窝板在长度和宽度方向上都可以拉伸和缩短，当玻璃钢复合管被挤压变形时，复合在玻璃钢管管壁中的蜂窝板随之稍作变形，而渗入填充在蜂窝孔内的树脂胶阻滞蜂窝板作较大变形，这样既能缓冲挤压，又能回弹形变，抗震抗压能力都大大提高，不容易变形损坏。

Description

一种抗震抗压的玻璃钢复合管及其制作方法
技术领域
本发明属于制作玻璃钢复合管的技术领域，具体是涉及一种抗震抗压的玻璃钢复合管及其制作方法。
背景技术
玻璃钢管以其独具的强耐腐蚀性能、内表面光滑、输送能耗低、使用寿命长(可达50年以上)、运输安装方便、维护成本低及综合造价低等诸多优势在石油、电力、化工、造纸、城市给排水、工厂污水处理、海水淡化、煤气输送等行业取得了广泛的应用。但玻璃钢管的弹性模量低，比钢(E＝2.1E5)要小十多倍，产品结构刚性不足，抗震抗压能力都较差，容易变形损坏。为此本领域技术人员对改性复合玻璃钢管作了很多努力，比如“一种复合玻璃钢管”(专利号：201310167732.5)，管壁由内向外依次由内衬层、增韧层、增强层和防护层为复合构成，其中内衬层由厚度为δ＝0.1-0.18mm的涤纶布和内衬浆料复合而成，内衬浆料由环氧树脂100重量份、稀释剂丙酮30-50重量份、固化剂7-8重量份制成；增韧层由厚度为δ＝0.16mm的碳纤维平纹布和增韧浆料复合而成，增韧浆料由不饱和聚酯树脂100重量份、固化剂2-5重量份、促进剂2-5重量份制成；增强层由厚度为δ＝0.2-0.4mm的玻璃纤维布和增强浆料复合而成，增强浆料由氧化镁10-15重量份、氯化镁1-2重量份、水15-20重量份、质量比浓度为20-30％的磷酸溶液1-1.5重量份、煤粉灰0.5-2重量份、锯末0.5-2重量份制成；防护层由厚度为δ＝0.1-0.2mm的100-500号芳纶纤维无捻粗纱和防护浆料复合而成，防护浆料由环氧树脂100重量份、稀释剂丙酮30-50重量份、固化剂7-8重量份制成。这种改性复合玻璃钢管，制作工艺非常复杂，制作要求非常高，致使生产成本非常高。
发明内容
本发明主要是解决现有技术所存在的技术问题，提供一种抗震抗压的玻璃钢复合管及其制作方法。
本发明的上述技术问题主要是通过下述技术方案得以解决的：一种抗震抗压的玻璃钢复合管，由玻璃钢内层、蜂窝板芯层和玻璃钢外层复合构成，其中蜂窝板芯层由蜂窝板绕制构成，所述蜂窝板中均布蜂窝孔，且蜂窝孔的孔径方向顺着蜂窝板的厚度方向，绕制后蜂窝孔沿复合管的径向设置，所述玻璃钢内层、蜂窝板芯层和玻璃钢外层三者的厚度相当，所述绕制蜂窝板芯层的蜂窝板为铝质蜂窝板或橡胶蜂窝板。
上述玻璃钢复合管的制作方法包括：步骤⑴，选用合适的钢质芯模，在钢质芯模表面涂刷油膜作为打底层；步骤⑵，由玻璃钢管制作装置带动钢质芯模转动，在钢质芯模上绕制第一层浸胶玻纤，然后静置；步骤⑶，待第一层浸胶玻纤的外表面微微固化时，先在第一层浸胶玻纤的外表面绕制第一层玻纤干布，并淋胶湿润，然后滚压使第一层玻纤干布表面平整，再在第一层玻纤干布的湿润外表面绕制一层蜂窝板，第一层玻纤干布可以使得适量的树脂胶渗入填充在蜂窝孔的内端口处，又能阻挡过多的树脂胶渗入填充在蜂窝孔内；步骤⑷，先在蜂窝板层的外面绕制第二层玻纤干布，然后在第二层玻纤干布的外表面绕制第二层浸胶玻纤，再静置，第二层玻纤干布可以使得适量的树脂胶渗入填充在蜂窝孔的外端口处，又能阻挡过多的树脂胶渗入填充在蜂窝孔内；步骤⑸，待第二层浸胶玻纤的外表面微微固化，在第二层浸胶玻纤的外表面包覆一层油纸，然后滚压使第二层浸胶玻纤的外表面平整光滑；步骤⑹，待浸胶玻纤完全固化，第一层浸胶玻纤和第一层玻纤干布构成玻璃钢内层，第二层玻纤干布和第二层浸胶玻纤构成玻璃钢外层，蜂窝板以及渗入填充在蜂窝孔内的部分树脂胶构成蜂窝板芯层，取出钢质芯模即得玻璃钢复合管。
本发明基于现有技术中玻璃钢管的定长缠绕工艺或连续缠绕工艺进行了改进，将蜂窝板复合在玻璃钢管的管壁中，蜂窝板层两侧的玻纤干布可以使得适量的树脂胶渗入填充在蜂窝孔内，但又能阻挡过多的树脂胶渗入填充在蜂窝孔内。蜂窝板在厚度方向上强度很高，复合在玻璃钢管的管壁中不会降低玻璃钢管管壁的强度，而蜂窝板在长度和宽度方向上都可以拉伸和缩短，当玻璃钢复合管被挤压变形时，复合在玻璃钢管管壁中的蜂窝板随之稍作变形，而渗入填充在蜂窝孔内的树脂胶阻滞蜂窝板作较大变形，这样既能缓冲挤压，又能回弹形变，因此复合在玻璃钢管管壁中的蜂窝板增加了玻璃钢管韧性，抗震抗压能力都大大提高，不容易变形损坏。
