OBJECT HEAT INSULATOR Russian patent published in 2010 - IPC A62C2/06 

FIELD: fire safety.

SUBSTANCE: invention is related to heat insulation, fire resistant coatings used for protection of various objects against high temperature effects. Heat insulator comprises insulating layers with fiber attached in between made of material with shape memory effect and arranged from a row of thin wires with round section from equiatomic titanium-nickel alloy. Each separate wire of fiber is initially coiled into helical spiral and is twisted relative to axis of rotation in plastic area till shift deformation, which is close to limit, by angle defined using calculated dependence. Melt of each separate wire is adjusted for phase conversion at critical temperature into rectilinear shape twisted versus axis of rotation and inverted helical spiral with number of turns that is twice less than the initial one, wires in fiber are equidistantly woven between each other and are fixed between insulation layers by means of connection threads, insulation layers and fiber are stitched with connection threads by means of free stitches, insulating layers and connection threads are made of heat resistant aramide composite.

EFFECT: invention provides for improved design of heat insulator, which provides for more efficient protection of equipment in extreme heat modes, for instance in case of fire or high temperatures in closed volumes, has sufficient resistance to aggressive mediums.
