STRUCTURAL MATERIAL AND A METHOD OF ITS PRODUCING Russian patent published in 1995 - IPC

FIELD: organic chemistry. SUBSTANCE: structural material has basalt fiber with polyvinyl acetate on its surface at their mass ratio (90-99): (1-10) at the following ratio of material components, wt.-% basalt fiber with polyvinyl acetate 30-45, and binder 55-70. Structural material has additionally aluminium hydroxide at concentration 2-25% with regard to basalt fiber mass. Method involves preliminary application of polyvinyl acetate aqueous emulsion taken at the mass ratio basalt fiber/polyvinyl acetate (90-99):(1-10), respectively, at the following ratio of material components, wt. -% basalt fiber with polyvinyl acetate 30-45, and binder 55-70. The source of polymeric binder: binder on the basis of phenolformaldehyde resin or epoxy resin, or a mixture of epoxy resin with phenolformaldehyde resin at the ratio 1: 1. Additionally, aluminium hydroxide is added to the parental components at concentration 2-25 to basalt fiber mass. EFFECT: enhanced quality of material. 6 cl, 2 tbl
