Lubricant for use in hot work

A lubricant for hot working, comprising, in the form of a mixture:

• (A) from about 10 to about 60 wt % of an alkali silicate;
• (B) from about 1 to about 20 wt % of a silane coupling agent;
• (C) from about 0.1 to about 5.0 wt % of at least one kind of an alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid;
• (D) from about 5 to about 50 wt % of water;
• (E) from about 10 to about 60 wt % of an iron oxide;
• and
• (F) from about 0.1 to about 5.0 wt % of at least one additive selected from a group consisting of a dispersant and a thickening agent, said weight % being based on the weight of the entire mixture.

A composition adapted for use as a lubricant, said composition being formed by mixing:

• (A) from about 10 to about 60 wt % of an alkali silicate;
• (B) from about 1 to about 20 wt % of a silane coupling agent;
• (C) from about 0.1 to about 5.0 wt % of at least one kind of an alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid;
• and
• (D) from about 30 to about 70 wt % of water, said weight % being based on the weight of the entire mixture.
