もので、塗型強度の向上を目的とするものである。(Problems to be Solved by the Invention) In the conventional coating mold strengthening method, there is a limit to the thickness of the refractory particles that adhere to the mold, and the adhesion state of the refractory particles changes depending on the application state of the slurry coating material, so that it cannot be uniformly coated. There is a problem in that it is difficult to form a suitable coating layer. Therefore, the present invention was devised to solve this problem, and its purpose is to improve the strength of the coating mold.

If the amount exceeds 30 parts by weight without being evenly crossed, the viscosity of the coating mold will become low and the adhesion to the foamed resin model will deteriorate.

る。(3) Glass fiber The glass fiber has a thickness of 2 to 50 μm and a length of 1 to 5 nm.
If the thickness is less than 2 μm, the reinforcing effect of the coated mold will be reduced, and if the thickness exceeds 50 μm, the fibers will easily become entangled with each other and will not be dispersed. Furthermore, if the length is less than 1 mm, the overlapping phenomenon will be difficult to occur and the strength of the coating mold will be reduced, and if the length exceeds 5+ nm, the fibrillation of the fibers will be insufficient and a bridging phenomenon will occur.

公知の方法に準じて行われる。The amount of glass fiber is 3 to 100 parts by weight of the refractory fine powder.
If it is added in an amount of 10 parts by weight, the effect of reinforcing the coating mold will be reduced, and if it exceeds 10 parts by weight, the dispersibility will be reduced. The method of adding and blending glass fiber is not particularly limited, and may be carried out according to various known methods.
