一种耐腐蚀的PE给水管的制备方法
摘要：
本发明公开了一种耐腐蚀的PE给水管的制备方法，包括以下步骤：1）按准备好各种所需的原材料；2）将原料中的聚乙烯、二异丙醇胺、2,4-二羟基苯乙酮、硫丙酸甲酯、硬脂酸、生育酚乙酸酯、粘土纳米复合材料放入高速混合搅拌机中，搅拌、喷淋，然后降温，得到混合物料A；3）将原料中的偏铝酸钙、二氧化钛、氧化锌放入气流粉碎设备中，粉碎，得到混合粉末B；4）将步骤2）制成的混合物料A放入混合搅拌机中，再加入步骤3）制得的混合粉末B，搅拌30min，制成混合物料C；5）将混合物料C挤入注射成型设备的腔室内，然后冷却定型，即可制得成品。采用本发明制备的耐腐蚀的PE给水管，具有耐腐性优异、强度高、韧性好的优点。
摘要（英）：

The invention discloses a corrosion resistant PE water pipe preparation method. The method includes 1, preparing various raw materials according to various requirements; 2, feeding the raw materials of polyethylene, diisopropanolamine, 2,4-dihydroxyacetophenone, methyl thiopropionate, stearate, tocopheryl acetate and clay nanocomposite material into a high-speed mixer, mixing, spraying, cooling, and obtaining the mixed material A; 3, feeding the raw materials of calcium aluminate, titania and zinc oxide into a gas stream pulverizing device for pulverizing, and obtaining the mixed material B; 4, feeding the mixed material A and the mixed material B into the mixer, mixing for 30min, and obtaining the mixed material C; 5, extruding the mixed material C into the cavity of injection and forming equipment, cooling, shaping, and obtaining a finished product. The pipe has the advantages of excellent corrosion resistance and high strength and toughness.
