Title:

FIBER CEMENT COMPOSITE MATERIAL USING BIOCIDE TREATED DURABLE CELLULOSE FIBERS

Document Type and Number:

WIPO Patent Application WO2002032830

Kind Code:

A9

Abstract:

A fiber cement composite material providing improved rot resistance and durability, the composite material incorporating biocide treated fibrous pulps to resist microorganism attacks. The biocide treated fibers have biocides attached to inner and outer surfaces of individualized fibers to protect the fibers from fungi, bacteria, mold and algae attacks. The biocides selected have strong affinity to cellulose and do not interfere with cement hydration reactions. This invention also discloses the formulation, the method of manufacturing and the final fiber cement products using the biocide treated fibers.
