A kind of cast copper sculpture material and the preparation technology of cast copper sculpture

Abstract

The invention relates to a cast copper sculpture material and a cast copper sculpture manufacturing process. The cast copper sculpture material comprises, by mass, 50-80 parts of bronze, 5-15 parts ofaluminum, 2-10 parts of zinc, 10-30 parts of silicon and 20-40 parts of iron. The cast copper sculpture manufacturing process comprises the steps that materials in above formula amount are smelted into liquid meeting the preset requirement; the liquid is poured into a pre-manufactured casting mould; and liquid in the casting mould is cooled and solidified, and sculpture works in preset shape is obtained after cleaning and polishing are carried out. The cast copper sculpture material comprises the bronze, the aluminum and the zinc, and further comprises the silicon and the iron in certain proportion, and therefore a manufactured cast copper sculpture has the good casting handling characteristic, the high acid resistance, alkali prevention, salt control and resistance to corrosion are achieved, the cast copper sculpture material and the cast copper sculpture manufacturing process are suitable for precision casting, coloring is stable, the national standard (38#) is met, the manufacturing cost can be reduced, and popularization of the cast copper sculpture is facilitated.

Description

technical field [0001] The invention relates to the technical field of sculpture, in particular to a casting copper sculpture material and a preparation process for casting copper sculpture. Background technique [0002] Because cast copper is produced by high-temperature melting and pouring, complex shapes can be made. It is widely used in figurative sculptures with figures as the main body, especially sculptures with complex shapes. Its characteristic is that it can ensure the shape and details handled by the sculptor in the mud draft relatively completely and accurately. It has rich shapes, steady effect and strong expressive force, especially in the aspects of character image, clothing and other details. But the hardness of cast copper sculpture itself is not enough. In order to ensure sufficient hardness, materials that can enhance hardness are added to the material or in the process of casting copper sculpture, support columns are added inside the sculpture. In addit...
