Preparation method of carbon fiber cured felt, carbon fiber cured felt and application of carbon fiber cured felt
The invention relates to the technical field of heat insulation and heat preservation, in particular to a preparation method of a carbon fiber cured felt, the carbon fiber cured felt and application of the carbon fiber cured felt. The preparation method of the carbon fiber cured felt comprises the following steps: mixing carbon fibers and a resin solution to prepare a carbon fiber suspension; carrying out solid-liquid separation treatment on the carbon fiber suspension to obtain a solid, and carrying out drying and dispersing treatment on the solid to enable the surface of the carbon fiber to be coated with the resin to prepare a carbon fiber intermediate product; carrying out hot-pressing curing molding treatment on the carbon fiber intermediate product to prepare a carbon fiber preform; and carrying out carbonization treatment, graphitization treatment and purification treatment on the carbon fiber preform to prepare the carbon fiber cured felt. The prepared cured felt material is uniform in density, high in purity and low in heat conductivity coefficient, has the advantage of being simple in process, can be subjected to large-scale industrial development, and effectively improves the profit of resin and the service life of a mold.
本发明涉及隔热保温技术领域，特别是涉及一种碳纤维固化毡的制备方法、碳纤维固化毡及其应用。本发明的碳纤维固化毡的制备方法包括如下步骤：将碳纤维和树脂溶液混合，制备碳纤维悬浮液；对所述碳纤维悬浮液进行固液分离处理获取固体，对所述固体进行干燥分散处理，使所述碳纤维的表面被所述树脂包覆，制备碳纤维中间产物；对所述碳纤维中间产物进行热压固化成型处理，制备碳纤维预制体；对所述碳纤维预制体进行碳化处理、石墨化处理和纯化处理，制备所述碳纤维固化毡。本发明制得的固化毡材料密度均一、纯度高、导热系数低，同时还具有工艺简单的优势，能进行大批量产业化发展，有效提高了树脂的利润和模具的使用寿命。
