Preparation process of high-temperature-resistant ceramic fiber board
The invention discloses a preparation process of a high-temperature-resistant ceramic fiberboard, and relates to the technical field of ceramic fiberboards, and the preparation process comprises the following steps: screening and grading ceramic fibers to obtain high-quality ceramic fibers, chopping the ceramic fibers, mixing the chopped ceramic fibers with a wet strength agent, alumina powder and silica sol, and dispersing to obtain a mixture; preparing a binding agent, carrying out flocculation and scattering on the mixture to obtain flocculated slurry in the mixture, and carrying out wet vacuum treatment to obtain a green body of the ceramic fiber board; and the green body is dried, heated and fired, and the high-temperature-resistant ceramic fiber board is obtained. According to the ceramic fiber board prepared by using the organic binding agent and the solvent, the filler and the fiber can be effectively combined, so that the performance of the ceramic fiber board is improved, and the use amount of the binding agent can be effectively reduced by using the ceramic fiber board prepared by adding the solution obtained by heating the organic binding agent into the suspension; the combination degree of the ceramic fiber and the filler is further improved.
本发明公开了一种耐高温陶瓷纤维板的制备工艺，涉及陶瓷纤维板技术领域，包括将陶瓷纤维进行筛选分级，得到质量较高的陶瓷纤维而后进行短切后与湿强剂、氧化铝粉料以及硅溶胶进行混合，经过分散后得到混合物；制备结合剂将混合物进行絮凝打散，得到混合物中的絮凝得到浆料，经过湿法真空后得到陶瓷纤维板的坯体；对坯体进行干燥加热烧制，得到耐高温的陶瓷纤维板。本发明通过利用有机结合剂加溶剂制成的陶瓷纤维板可以让填充料和纤维有效结合，从而提高陶瓷纤维板的性能，利用有机结合剂加热后的溶液再加入到悬浮液中制成的陶瓷纤维板可以有效减少结合剂的使用量，进一步提高陶瓷纤维和填充料的结合程度。
