    Abstract: A composition comprising (a) fine spherical particles of an inorganic substance such as alumina, (b) an aqueous adhesive agent such as a petroleum resin emulsion, and water. It is preferred for better effect that the composition further comprises one or more selected from among (c) a wisker, (d) a powder of an inorganic substance in a form of a scaly crystal, (e) a powder of a metal hydroxide or an inorganic substance having bound water, and (f) a lubricant aid. The composition is free from problems of the occurrence of environmental pollution and the risk of misoperation of an automatic machine, which accompany a conventional graphite lubricating and releasing agent, and that of the danger of smoking or firing, which accompanies a conventional lubricating and releasing agent dispersed in an oil, and is useful as an aqueous lubricating and releasing agent for hot or cold forging using a non-graphite inorganic substance, which is free from occurrence of the deposition on a mold and an under fill phenomenon.

    Abstract translation: 一种组合物,其包含(a)无机物质如氧化铝的细球形颗粒,(b)水性粘合剂如石油树脂乳液和水。 优选的是,组合物还包含选自以下的一种或多种(c)晶须,(d)鳞片状晶体形式的无机物质的粉末,(e)金属氢氧化物的粉末或 具有结合水的无机物质,和(f)润滑剂助剂。 该组合物没有常规润滑和脱模剂伴随常规石墨润滑和脱模剂的伴随环境污染和自动机器误操作的风险以及吸烟或烧制的危险。 分散在油中,并且可用作使用非石墨无机物质的热或冷锻造的水性润滑和脱模剂,其不会发生在模具上的沉积和填充不足现象。
