Abstract
A fire-retardant composition of matter is produced as the dried and pulverized reaction product of treating a calcium, sodium, magnesium, or potassium borate ore with sulfuric acid. The composition is especially useful for application as a dry powder to cellulosic materials, but may be made into a liquid suspension for spray application or into a paste for some fire retardant applications.
Claims10
A fire-retardant compositon of matter, comprising a particulate reaction product of a borate ore and sulfuric acid, said one having been selected from the group consisting of calcium, sodium, magnesium, and potassium borates, and mixtures thereof and said composition containing boric acid as a constituent of said reaction product, and a significant quantity of one or more sulfates selected from the group consisting of calcium, sodium, magnesium, and potassium sulfates, as a constituent of said reaction product.
A process for producing a fire-retardant composition of matter, comprising reacting a pulverized borate ore selected from the group consisting of calcium, sodium, magnesium, and potassium borates mixtures thereof, with sulfuric acid for a time sufficient to produce a reaction product containing a boric acid constituent and a sulfate constituent;
- drying the reaction product containing said constituents;
- and pulverizing the dried reaction product.
