Abstract

The invention relates to the technical field of aluminum alloy templates, in particular to an aluminum alloy template and a preparation method thereof. The aluminum alloy template comprises an aluminum alloy plate base material layer and a surface layer, the surface layer is arranged on one face of the aluminum alloy base material layer, the aluminum alloy base material layer and the surface layer are integrally formed, the aluminum alloy base material layer comprises the following raw materials of, in parts by weight, 0.45-0.65 parts of lithium, 0.28-0.42 parts of magnesium, 0.56-0.78 parts of beryllium bronze, 0.06-0.12 parts of silicon, 0.15-0.33 parts of zinc and 97.7-98.5 parts of aluminum ingots, a copper content of the aluminum ingots is less than or equal to 0.1%, an iron content of the aluminum ingots is less than or equal to 0.2%, and the surface layer is a fiber reinforced composite material. The aluminum alloy template is used for solving the problems that an existing aluminum alloy template is insufficient in strength and prone to deformation in a using process due to shrinkage cavities and looseness in a casting process, and the aluminum alloy template can be detached only by using a release agent.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy templates, in particular to an aluminum alloy template and a preparation method thereof. Background technique [0002] The building formwork is composed of a panel and a support system. The panel is the part that makes the concrete shape; the support system is the structural part that stabilizes the position of the panel and bears the upper load. The quality of the formwork is related to the quality of the concrete project, and the key lies in accurate size, firm assembly, tight joints, and convenient assembly and disassembly. Appropriate formwork should be selected according to the form and characteristics of the building structure in order to achieve good technical and economic results. [0003] However, there are still problems in the preparation process of aluminum alloy templates. The melting points of different metals are very different. Therefore, aluminum alloys have a very wide so...
