Superfine ceramic fiber cotton thermal insulation pipe shell and preparation method thereof
The invention belongs to the technical field of thermal insulation materials, and provides a superfine ceramic fiber cotton thermal insulation pipe shell and a preparation method thereof. Superfine ceramic fiber cotton is used as a main raw material, a binder capable of improving the compressive strength of the product, a slurry gelatinizing agent capable of improving the distribution uniformity of the superfine ceramic fiber cotton in slurry, a slurry regulator capable of regulating the flowability of the slurry and a water repellent capable of improving the hydrophobicity of the product are added at the same time, and gelatinization, pulping, deslagging and suction filtration forming are carried out, so that the superfine ceramic fiber cotton composite material is obtained. Prefabricated production of the heat preservation pipe shell is achieved, and the superfine ceramic fiber cotton heat preservation pipe shell high in strength and good in hydrophobicity is obtained. The result of the embodiment shows that the density of the superfine ceramic fiber cotton thermal insulation pipe shell prepared by the preparation method provided by the invention is 186kg/m < 3 >, the hydrophobic rate is 99.2%, the volume water absorption rate is 2.3%, the heat conductivity coefficient (at the average temperature of 70 DEG C) is 0.50 W/(m.K), and the compressive strength is 83KPa.
本发明属于保温材料技术领域，提供了一种超细陶瓷纤维棉保温管壳及其制备方法。本发明以超细陶瓷纤维棉为主要原料，同时添加能够增加产品抗压强度的粘结剂、改善超细陶瓷纤维棉在浆体中分布均匀性的浆体糊化剂、调节浆体流动性的浆体调节剂以及提高产品憎水率的憎水剂，经糊化、打浆排渣和吸滤成型，实现了保温管壳的预制化生产，得到了强度高、憎水性好的超细陶瓷纤维棉保温管壳。实施例的结果显示，本发明提供的制备方法制备的超细陶瓷纤维棉保温管壳的密度为186kg/m3，憎水率为99.2％，体积吸水率为2.3％，导热系数(平均温度70℃下)为0.50W/(m·K)，抗压强度为83KPa。
