HEAT RESISTANT AND FIRE RETARDANT MATERIALS AND METHODS FOR PREPARING SAME

摘要

A silica cement blend having an insulating, fire retarding and high temperature characteristic capable of withstanding temperatures ranging from ambient to greater than 40000F without degradation of the concrete structure. In addition to its high temperature capabilities the blend can be produced as ultra light weight to heavy weight concrete. The silica based mixture when added to cementitious materials such as Portland cement, Class C Fly Ash, silica fume and other cementitious materials. Presented also are methods for reducing fire damage by coating interior/exterior walls, ceiling, and roofs of a building with a water based latex coating containing a fire retardant material and low heat conductivity silicas. Methods for painting internal/external walls, ceilings, and roof are also presented. This coating retains thermal blocking properties comprised of processed, expanded and/or finely milled, pyrogenic silicas and micro spheres in combination of but not limited to, one, two or more component water based polymer/copolymer latex binders and a water born fluoropolymer emulsion. The combined properties of these elements create a coating similar to paint with a high level of thermatic resistance which slows the composition break-down from fire, extreme temperatures, and restricts the thermal conductivity which helps to preserve the integrity of the substructure or underlying materials. The properties of this coating reduce or slow the potential of catastrophic fire by retarding flashover and protecting the under structure; which in turn assist fire fighters and rescue personnel by helping to retard the potential of a catastrophic fire.
