Abstract
The method of modifying an organic material including rubber and plastics which consists in the steps of embodying in the organic material during manufacture of the glycerato-zinc complex (C.sub.3 H.sub.6 O.sub.3 Zn) which is manufactured by heating a zinc compound and glycerol to a temperature below the boiling point of the glycerol to form crystals having substantial two-dimensional extension but low thickness and orientating the crystals selectively to improve tensile strength and reduce ultraviolet light degradation of the organic material.
Claims11
A method of modifying an organic material selected from diene rubber and plastic comprising the steps of (a) embodying in said organic material, during manufacture thereof, an ultraviolet light ray shielding and bonding agent comprising a glycerato-zinc complex (C.sub.3 H.sub.6 O.sub.3 Zn) prepared by heating a zinc compound and glycerol to a temperature below the boiling point of said glycerol and continuing said heating to form crystals of generally hexagonal morphology having substantial two-dimensional extension but low thickness and (b) selectively arranging the crystals of said glycerto-zinc complex in said organic material, whereby to improve tensile strength of thus modified organic material and to reduce deterioration of said organic material by light in the ultraviolet wave length.
An organic material selected from diene rubber and plastic having included therein platelets or glycerato-zinc complex (C.sub.3 H.sub.6 O.sub.3 Zn) prepared by heating a zinc compound and glycerol and continuing said heating to form platelets of a generally hexagonal morphology having substantial two-dimensional extension in one plane but low extension in a plane normal thereto, said complex being present in an amount sufficient to improve the tensile strength of said organic material and to reduce deterioration of said organic material by light in the ultraviolet wavelength.
