Mica material composition, mica tube as well as preparation method and application of mica tube
The invention relates to the technical field of insulating materials, and particularly discloses a mica material composition, a mica tube and a preparation method and application of the mica tube. The mica material composition provided by the invention is prepared from the following components in parts by weight: 75 to 85 parts of mica powder, 35 to 55 parts of polyethylene, 45 to 55 parts of silica powder and 25 to 35 parts of organic silica gel, the invention also provides a mica tube prepared from the mica material composition, and a preparation method of the mica tube comprises the following steps: extruding the mica material composition at an extrusion temperature of 170-190 DEG C, and then carrying out air cooling at 20-30 DEG C for more than or equal to 20 min to obtain a mica tube preform; and drying to obtain the mica tube. According to the mica tube, the mica material composition is subjected to extrusion forming, the prepared mica tube is seamless, the normal-temperature insulativity of the mica tube is good, the high-temperature fire resistance of the mica tube is good, and the use requirement of an insulating layer of an electric shock rod or a waterproof sleeve can be met.
本申请涉及绝缘材料技术领域，具体公开了一种云母料组合物、云母管及其制备方法与应用。本申请提供的云母料组合物包括以下重量份的组分：云母粉75‑85份、聚乙烯35‑55份、硅微粉45‑55份和有机硅胶25‑35份；本申请还提供了利用上述云母料组合物制得的云母管，所述云母管的制备方法包括以下步骤：将所述云母料组合物在170‑190℃的挤出温度下挤出，然后在20‑30℃下气冷≥20min，获得云母管预制体；经烘干，获得的云母管。本申请通过将云母料组合物挤压成型，制得的云母管全管无缝，并且该云母管的常温绝缘性好、高温耐火性佳，能够满足电击棒或防水套管绝缘层的使用要求。
