Basalt fiber reinforced polypropylene pipeline and preparation method thereof
The invention relates to the technical field of plastic pipelines, and particularly discloses a basalt fiber reinforced polypropylene pipeline which sequentially comprises an inner layer, a middle reinforcing layer and an outer layer, the inner layer and the outer layer are PP-R resin layers, and the basalt fiber reinforced polypropylene pipeline is characterized in that the middle reinforcing layer is a basalt fiber reinforced PP-R composite material, and the outer layer is a PP-R resin layer. Wherein the PP-R composite material is prepared by compounding 100 parts of PP-R resin, 10-30 parts of modified basalt fibers, 1-5 parts of a compatilizer, 0.1-3 parts of an initiator and 0.1-3 parts of an antioxidant, and the modified basalt fibers are obtained by etching basalt fibers and then modifying the basalt fibers with a maleic anhydride-silane coupling agent copolymer. The invention relates to a preparation method of a basalt fiber reinforced polypropylene pipeline. The basalt fiber reinforced polypropylene pipeline is obtained by melting and extruding a PP-R composite material and PP-R materials on the inner layer and the outer layer of the pipeline through a three-layer extruder. The scheme is used for solving the problems that an existing pipeline is poor in low temperature resistance, and pits and protrusions exist on the inner wall of the pipeline.
本发明涉及塑料管道技术领域，具体公开了一种玄武岩纤维增强聚丙烯管道，依次包括内层、中间增强层和外层，内层、外层均为PP‑R树脂层，其特征在于：中间增强层为玄武岩纤维增强的PP‑R复合材料，其中PP‑R复合材料由100份PP‑R树脂、10‑30份改性玄武岩纤维、1‑5份相容剂、0.1‑3份引发剂、0.1‑3份抗氧化剂复配而成，其中改性玄武岩纤维由玄武岩纤维经刻蚀后再经马来酸酐‑硅烷偶联剂共聚物改性而得。一种玄武岩纤维增强聚丙烯管道的制备方法，包括将PP‑R复合材料与管道内外层的PP‑R材料经三层挤出机熔融挤出得到玄武岩纤维增强聚丙烯管道。本方案用以解决现有的管道存在耐低温性能差以及管内壁存在凹坑凸起的问题。
