縮するのを防止するようにした石膏成形体に含浸させろ
含浸液に関するものである。Detailed Description of the Invention The present invention provides a gypsum molded product which is impregnated into a gypsum molded product to prevent resin content from volatilizing from the surface of the gypsum molded product and to prevent the gypsum molded product from shrinking during hardening. This relates to an impregnating liquid.

、軟質の石膏成形体に樹脂液を含浸させて石膏成形体を
硬化させろ場合があった。Conventionally, flexible plaster, which is easy to process, is processed to produce prototypes for statues, building materials, molds, etc., and in order to ensure that the plaster moldings last for a long time, the soft plaster moldings are impregnated with resin liquid and then plaster molded. There were times when I had to harden my body.

が悪かった。By the way, as the impregnating liquid for curing this gypsum molded body, impregnating liquids mainly made of polyester or incyanate were used for acrylic threads and oligomers, but
When such an impregnating liquid is used, the resin content evaporates from the surface of the gypsum molding and no resin remains on the surface of the gypsum molding, resulting in poor strength, chemical resistance, and water resistance of the gypsum molding, resulting in poor surface properties. was not improved, and the condition was extremely bad for the gypsum molded body.
また石膏成形体が含浸液により硬化する場合は石膏成形

待されていた。Furthermore, impregnation caused various inconveniences such as distortion of the gypsum molded body and cracks in the gypsum molded body.
It was hoped that an impregnating liquid would be developed that would further improve the surface properties of gypsum molded bodies.

したものである。Therefore, in view of the current situation, the present invention aims to solve the above-mentioned drawbacks by adding 100 parts by weight of methyl methacrylate to 100 parts by weight of methyl methacrylate.
0-200 parts by weight, diphenylethane or methane 5
By providing an impregnating liquid for gypsum molded bodies in a ratio of ~200 parts by weight and 0.05 to 5.0 parts by weight of peroxide, it is possible to prevent the resin from evaporating from the surface of the gypsum molded body. , the shrinkage of the gypsum molded body during hardening is reduced.

部の割合で配合させるものである。Methyl metal acrylate, which is the main component of the impregnating liquid of the present invention, has the property of being easily permeable but easily volatilized. Therefore, this methyl metal acrylate was mixed with penzole peroxide or azobisisoputilonyl-IJ for 30 minutes.
% polymerized and stopped with a polymerization terminator,
By mixing and using methyl metal acrylate, it becomes easy to impregnate and difficult to volatilize. Further, when polymerizing with an organic peroxide such as penzole peroxide or azobisisobutyronitrile, the gypsum molded body can be uniformly hardened without any time lag. At this time, the blending ratio of methyl methacrylate and penzole peroxide is such that penzole peroxide is blended with respect to methyl methacrylate, and a polymerization terminator such as hydroquinone is used to obtain a 30% polymer of methyl methacrylate. And, based on 100 parts by weight of the methyl methacrylate, a 30% polymer of this methyl methacrylate YIO~200
It is to be blended in the proportion of 1 part.
