関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a method for manufacturing a glass mold or a metal mold such as stainless steel.
The present invention relates to a casting composition with improved mold releasability, which provides cast products with good productivity and good surface properties when used for heavy casting.

とが困難となる。Aliphatic alcohols, fatty acids, fatty acid esters, and metal soaps are used as mold release agents in cast polymerization of methacrylic resin casting plates or styrene resin casting plates that are manufactured industrially using glass molds or metal molds such as stainless steel. and anionic surfactants are effective. However, in order to improve the thermal and mechanical properties of these resins, unsaturated carboxylic acids and/or unsaturated carboxylic anhydrides are used as carrier suspensions, which reduces the effect of the above-mentioned mold release agents and reduces surface defects. It becomes difficult to stably obtain a beautiful cast product without blemishes.
これに対して、上記離型剤を多量に添加するととしに、

く低下している。On the other hand, when adding a large amount of the above mold release agent,
A silane-based or fluorine-based mold release agent is applied to the surface of the mold before polymerization, but in this method, a large amount of mold release agent is used and the surface of the casting mold is coated in advance. Since the process of applying a mold release agent is added, the occurrence of cow beating is significantly reduced.

In the alkyl acid phosphate represented by 3-1, n is an integer of 8 to 13, and m = 1 or 2.
It is. When the value of n is 7 or less and 14 or more, there is an effect of improving the mold release property, but it is not sufficient, and peeling defects tend to occur in some parts, and it is necessary to use the other general mold release agents mentioned above.

The amount is 1 to 1.0 parts by weight, preferably 0.01 to 0.2 parts by weight. If it is less than 0.001 weight and 1 part, the effect of improving mold releasability is poor, and if it exceeds 1.0 Φ hanging part, the effect of improving mold releasability is very strong, but on the contrary, it tends to cause sink marks, which is not preferable.
