Abstract
A fire resistant material comprising a rigid sheet impregnated with a binder composition comprising alkali metal silicate, and sugar in an aqueous solution having a specified density, and coated with a composition comprising brick dust, silica and saw dust all having predetermined particle sizes, in combination with the binder composition. The impregnated sheets are allowed to harden and may be used as fire retardant building materials in the construction of various structures.

A fire resistant material comprising a rigid sheet impregnated with a binder composition comprising, by volume:
- two to three parts alkali metal silicate solution having a density in the range of 40.degree. to 41.degree. Be';
- and
- one part sugar in aqueous solution, said sugar solution having a density of approximately 10.degree. to 15.degree. Be';
- said impregnated rigid sheet being coated with a coating composition comprising:
- one volume non-metallic powder selected from the group consisting of brick dust, kaolin, talc, pyrophyllite, mica, calcium carbonate, calcium sulfate, and volcanic rock powder;
- one volume silica;
- two volumes of fine mesh saw dust;
- and
- two and one half volumes of said binder composition.
A method of producing a fire retardant material comprising the steps of:
- a. making a binder composition comprising:
- two to three parts alkali metal silicate having a
- density in the range of 40.degree. to 41.degree. Be';

- one part aqueous sugar solution having a density of 10.degree. to 15.degree. Be';
- b. making a paste solution comprising:
- one volume of non-metallic powder, said non-metallic powder being selected from the group consisting of brick dust, kaolin, talc, pyrophyllite, mica, calcium carbonate, calcium sulfate, and volcanic rock powder;
- one volume of silica;
- two volumes of fine particle saw dust;
- and
- two and half volumes of said binder composition from step a;
- c. impregnating a rigid material with the composition of step a;
- d. draining said impregnated rigid material;
- e. coating said impregnated rigid material with the composition of step b;
- and
- f. drying said coated rigid material.
