Carbon fiber net reinforced aluminum-carbon sliding plate brick and preparation method thereof
The invention particularly relates to a carbon fiber net reinforced aluminum-carbon sliding plate brick and a preparation method thereof. According to the technical scheme, the preparation method comprises the following steps: respectively oxidizing a cut square-hole carbon fiber net and chopped carbon fibers in an air atmosphere, respectively dipping the square-hole carbon fiber net and the chopped carbon fibers in a precursor solution, and drying to respectively obtain a pre-treated carbon fiber net and pre-treated chopped carbon fibers; mixing white corundum fine powder, crystalline flake graphite, carbon black, silicon powder, activated aluminum oxide powder, boron carbide powder and the pretreated short carbon fibers to obtain pretreated powder; white corundum particles with the particle size larger than 1 mm and smaller than or equal to 3 mm, white corundum particles with the particle size larger than 0.075 mm and smaller than or equal to 1 mm, pretreatment powder and thermosetting phenolic resin are evenly mixed, a mold is filled with the mixture, 1-3 layers of pretreated carbon fiber nets are evenly placed in the mixture of the mold, forming, drying, curing and firing are conducted, and the carbon fiber net reinforced aluminum carbon sliding plate brick is obtained. The prepared product is excellent in mechanical property and thermal shock resistance.
本发明具体涉及一种碳纤维网增强的铝碳滑板砖及其制备方法。其技术方案是：将裁剪的方孔碳纤维网和短切碳纤维分别置于空气气氛中氧化，再分别浸渍于前驱体溶液中，干燥，分别得预处理碳纤维网和预处理短切碳纤维。然后将白刚玉细粉、鳞片石墨、炭黑、硅粉、活性氧化铝粉、碳化硼粉和预处理短切碳纤维混合，即得预处理粉。将粒径大于1mm且小于等于3mm白刚玉颗粒和粒径大于0.075mm且小于等于1mm白刚玉颗粒、预处理粉和热固性酚醛树脂混合均匀，填充模具中，模具的混合料中均匀放有1～3层预处理碳纤维网，成型，干燥，固化，烧成，制得所述碳纤维网增强的铝碳滑板砖。本发明所制制品力学性能和抗热震性能优异。
