Description

Technical Field

[0001] The utility model relates to the technical field of composite carbon fiber thermal insulation tube preparation, in particular to a molding die for preparing the composite carbon fiber thermal insulation tube. Background Art

[0002] With the development of photovoltaic, semiconductor and high-temperature industrial furnace industries, the demand for thermal insulation materials is also increasing. Traditional thermal insulation materials have low operating temperatures (<1800℃), high pollution, and are difficult to make into thin thermal insulation layers, which occupy the space inside the furnace, thereby wasting the space inside the high-temperature furnace. The new carbon fiber thermal insulation material has become the most important thermal insulation material for high-temperature furnaces due to its excellent properties such as low thermal conductivity, low heat capacity, low density, low linear expansion coefficient, high temperature resistance, strong heat shock resistance, strong chemical corrosion resistance, high purity and no pollution.

[0003] Carbon fiber insulation materials are divided into carbon fiber soft felt and carbon fiber hard felt. The composite carbon fiber insulation tube is a carbon fiber composite material formed by carbon fiber and binder (resin). Due to its excellent mechanical properties, strong antioxidant properties, and easy disassembly and splicing, it occupies a large proportion in the application market of insulation materials. There are two traditional molding methods for preparing composite carbon fiber insulation tubes: one is to impregnate a thin layer of soft carbon felt with a thermosetting resin solution, wind it onto a mold, and obtain a blank after curing, carbonization and graphitization, and then machine it. However, in the barrel material obtained by this method, a large amount of adhesive is inevitably used between the layers because of the layer-by-layer bonding, which easily causes the material density to be too high, and there are obvious boundaries between the layers of thin felt, resulting in thermal field instability, high-temperature cracking and other problems. Another molding method is to use short-cut carbon fiber, dispersant, binder and solvent, etc., and form it by vacuum filtration. This method is time-consuming, has a large amount of solvent and high energy consumption, and has relatively low production efficiency. For this reason, we propose a molding mold for preparing a composite carbon fiber insulation tube. Utility Model Content
