Abstract

The invention belongs to the technical field of impression, and particularly relates to an impression material as well as a preparation method and application thereof. The impression material provided by the invention is prepared from the following raw materials in parts by weight: 40 to 80 parts of rice bran and/or wheat bran, 5 to 18 parts of a thickening agent, 1.4 to 4.5 parts of a retarder, 7 to 24 parts of a gelling agent, 0.9 to 3 parts of a reinforcing agent and 0.8 to 2.5 parts of a conditioning agent. According to the impression material provided by the invention, the rice bran and/or the wheat bran are/is taken as main filler, and the thickening agent, the retarder, the gelling agent, the reinforcing agent and the conditioning agent are matched for use, so that the obtained impression material has proper initial setting time, and a prepared female mold has excellent replication reproducibility, elastic recovery capability, compression strain capability and tear resistance.

Description

technical field [0001] The invention belongs to the technical field of stamping, and particularly relates to a stamping material and a preparation method and application thereof. Background technique [0002] The impression material is the material used in the preparation of the negative mold. The impression material should be elastic, with good fluidity and plasticity; after solidification, the physical properties are stable, the shape and volume do not change, the solidification time is appropriate, and the model is easy to take out after solidification. It is chemically changed with the model itself, easy to separate, and has good tear resistance. [0003] Existing impression materials mainly use mineral earth materials such as diatomite, kaolin, bentonite, etc. or starch-based materials as main fillers. However, the above materials have some defects: first, the mineral earth materials are not renewable, and they cannot be degraded after use. It will have some impact on ...
