Hard insulation felt and preparation method thereof
The invention discloses a hard insulation felt and a preparation method thereof, and the preparation method comprises the following steps: applying a dipping composition into a carbon fiber felt to obtain a dipping felt body; the impregnation composition comprises white carbon black, and the white carbon black is adhered to the carbon fiber felt in the impregnation process; carrying out carbonization treatment and graphitization treatment on the impregnated felt body, so that white carbon black in the impregnated felt body reacts with carbon fibers in the carbon fiber felt to generate silicon carbide, and obtaining a felt body unit; and the multiple felt body units are bonded through a bonding agent, and the hard heat preservation felt is obtained. The preparation method is simple and low in production difficulty, white carbon black and carbon fibers adhered to the carbon fiber felt react at a high temperature through carbonization treatment and graphitization treatment to generate silicon carbide, the strength and heat preservation performance of the hard heat preservation felt are synergistically improved while the density of the hard heat preservation felt is not obviously increased, and the service life of the hard heat preservation felt is prolonged. And the service life of the hard insulation felt is prolonged.
本申请公开了一种硬质保温毡及制备方法，包括将浸渍组合物施加至碳纤维毡中，得到浸渍毡体；所述浸渍组合物包括白炭黑，所述白炭黑在浸渍过程中粘附在所述碳纤维毡上；对所述浸渍毡体进行炭化处理和石墨化处理，以使得所述浸渍毡体中白炭黑与所述碳纤维毡中的碳纤维反应生成碳化硅，得到毡体单元；通过粘接剂将多个所述毡体单元粘接，得到所述硬质保温毡。本申请的制备方法简单，生产难度低，通过炭化处理和石墨化处理使得碳纤维毡上粘附的白炭黑与碳纤维在高温下反应生成碳化硅，在未明显增加硬质保温毡密度的同时，协同提升硬质保温毡的强度和保温性能，延长硬质保温毡的使用寿命。
