工場で使用されている。この為、離型剤が原因の
工場火災がしばしば発生する実情である。 Conventionally, green sand mold release agents for casting generally contain fatty acids,
Waxes, esters, oils, surfactants, etc. dissolved in petroleum solvents are mainly used. Kerosene is often used as this petroleum solvent, and most of its flash points are around 50°C, and mold release agents with temperatures below 30°C are actually used in foundries. For this reason, factory fires often occur due to mold release agents.
さらに、従来の離型剤は省資源、脱石油といつ

合もある。 Furthermore, conventional mold release agents are not only unable to meet the demands of the era of resource conservation and oil-free use, but their use is also constrained by both supply difficulties and high prices. On the other hand, in terms of performance, the above-mentioned conventional mold release agents may show a decrease in mold release performance due to increases in sand temperature, use of hard chrome plating models, etc.

とする。 Oil-soluble mold release agents, which are one of the main ingredients, are made by dissolving fatty acids, waxes, esters, oils and fats, surfactants, etc. in kerosene or similar petroleum solvents.
Alternatively, a conventional general mold release agent, such as one obtained by adding a nonflammable solvent such as a halogenated solvent, may be used, but the flash point must be 55° C. or higher.

果も期待できない。 Another main component of the present invention is water. Its main functions include (1) imparting flame retardancy, (2) serving as a substitute for petroleum, and (3) having a viscosity adjusting effect.
Without this water, the emulsion of the present invention cannot be produced nor can the effects of the emulsion be expected.

不可能となり本発明としての特徴はなくなる。 Next, as a result of examining the water content that should be included in the emulsion of the present invention, it was found that water should be at least
10% or more is required, and if it is less than 10%, a flash point of 55°C or higher is observed, making it difficult to provide a mold release agent that has no flash point and is flame retardant, which is a feature of the present invention. becomes. Furthermore, if the weight ratio of water exceeds 60%, it becomes impossible to obtain a stable water-in-oil emulsion, and the characteristics of the present invention are lost.

の存在下で含有することにより難燃性であり火
災の心配が少ない。 Next, we will summarize the main effects obtained by using the green sand mold release agent of the present invention in comparison with conventional general mold release agents. This is an effect obtained by dispersing water in the state of a water emulsion. Specifically, the water content is 10 to 60% by weight, and this water forms a release oil film and By containing it in the presence of a weight ratio, it is flame retardant and there is little fear of fire.
前記水の存在により、石油の節約が可能であ
る。 The presence of water allows oil savings.
水の存在下により粘度の上昇が達成される。
これにより、離型膜は質的、量的両面から強化
されることにより、抜型抵抗が減少し、離型し
やすくなること。 An increase in viscosity is achieved in the presence of water.
This strengthens the mold release film both qualitatively and quantitatively, reducing mold removal resistance and making mold release easier.
残留油膜が形成されることにより、一回の吹
き付けで造型可能な鋳型の個数が多く、造型コ
ストの低下に大きく寄与する。 By forming a residual oil film, a large number of molds can be molded with one spraying, which greatly contributes to lower molding costs.
エマルシヨン中に分散している水と生砂との
親和力により、含水の離型油膜が形成されると
ともに、鋳型の表面強度が増加し、型落ち、し
みつきなどの不良が防止されること。 Due to the affinity between the water dispersed in the emulsion and green sand, a water-containing mold release oil film is formed, and the surface strength of the mold is increased, preventing defects such as mold dropping and staining.
砂温度の上昇に対しても離型性能は安定して
いる。 The mold release performance is stable even when the sand temperature increases.
硬質クロムメツキ模型に使用しても優れた効
果が期待できる。それは前記粘度の上昇による
離型膜の質的、量的向上とクロムメツキとのな
じみによると思われる。 Excellent effects can be expected even when used on hard chrome plating models. This is thought to be due to the qualitative and quantitative improvement of the release film due to the increase in viscosity and the compatibility with chrome plating.
以下、実施例にもとづき本発明を説明する。 The present invention will be described below based on Examples.

2.0% The flash point of the prototype product obtained by stirring the above formulation in a mixer at 3600 revolutions per minute for 20 minutes is a stable water-in-oil emulsion. This prototype was made into a cast iron model with five pulleys.
After applying it by spraying 4.5ml, it was continuously molded (molding machine: Hunter). As a result, the number of moldings that could be continued with one application was 6.3 (average value of 9 experiments), and no molding defects such as staining or mold removal were observed during this period.
