Abstract

The invention discloses a wear-resistant and high-toughness material for 3D printing ceramic, belongs to the field of ceramic materials, and solves the problem of poor wear resistance and toughness ofcommon ceramic materials at present. The ball milling efficiency can be improved by adding kerosene and absolute ethyl alcohol as ball milling media, and combustion of the kerosene can promote unoxidized metal components in a ball milling material to have a redox reaction. Aluminum oxide contained in fly ash and an Mg<2+> component in palygorskite can produce a magnesia-alumina spinel component with erosion resistance and abrasion resistance at high temperature. A boron oxide component contained in boric sludge added to aids is acid anhydride of boric acid, the acid anhydride can produce boric acid and metaboric acid with water and emit a lot of heat, a boehmite component is embedded in a hard roasted product to improve dispersity and binding force among structures, external friction canbe well scattered, quick wear can be avoided, adsorption can be formed in combination with acrylic resin, the structure compactness of a material system can be improved, and tensile strength and wearresistance can be improved.

Description

technical field [0001] The invention belongs to the field of ceramic materials, and in particular relates to a wear-resistant and high-toughness material for 3D printing ceramics. Background technique [0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology and is known as the core technology of the "third industrial revolution". Compared with traditional manufacturing technology, 3D printing does not need to manufacture molds in advance, does not need to remove a large amount of material during the manufacturing process, and can obtain the final product without going through complicated forging processes. Therefore, structural optimization and material saving can be achieved in production. and save energy. 3D printing technology is suitable for new product development, rapid single-piece and small-batch parts manufacturing, complex-shaped parts manufacturing, mold design and manufacturing, etc., and is also suitable for the manu...
