Anti-vibration heat-insulation structure and a process for production thereof

摘要

The present invention relates to an anti-vibration heat-insulation structure and a process for the production thereof characterized by filling the void in the structure to form a heat-insulation layer with silicic acid bonding agent-coated silicic acid mineral grains which swell in volume when fired at a high temperature; and then heating and thereby expanding these silicic acid mineral grains and at the same time allowing said grains to stick to one another.
