Abstract
The invention relates to a plaster mold, which comprises the following components by weight part: 10-15 parts of carbon fiber, 5-10 parts of rosin, 1-3 parts of transformer oil, 5-10 parts of rare earth, 8-12 parts of tungsten powder, 4-8 parts of adhesive, 1-3 parts of magnesium and 3-5 parts of quartz sand. The plaster mold has the advantages that the composition proportion is scientific and reasonable, fine seam can not be generated during a usage process, service life is greatly prolonged, and enterprise requirement can be satisfied.
Description
technical field [0001] The invention relates to a plaster mold. Background technique [0002] Plaster molds are widely used in every field. Due to the limitation of enterprise production and traditional technology, it is harmful to the model itself. It will cause premature aging of the model and shorten the service life. This is because the model has a large water content. The internal structure of the model will be severely corroded and damaged. After the plaster mold has been used many times, many cavities will appear on the inner surface, and there will be relatively serious seams at the joints such as the edge of the mold, and the plaster mold has reached the scrapping requirement. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0004] The invention provides a plaster mold. [0005] The technical scheme adopted in the present invention is: [0006] A plaster mold comprising the following co...
