INORGANIC COMPOSITE STRUCTURES ENHANCED BY ORGANIC COMPOUNDS

摘要

A composite structure is prepared from an aqueous slurry comprising a mixture of an inorganic material and a cellulose ether additive. The inorganic material hydrates in the presence of the additive to form a composite core substantially reinforced by the additive. Fibers, such as sized glass fibers, may be added to the slurry to synergistically improve the strength of the composite structure by combining with the additive. The concentration, viscosity grade and degree of substitution of the cellulose ether additive are selected to give the composite substantially improved nail pull resistance or flexural strength or both.
