A wall cancer production inhibiting material comprising a mixture of modified montmorillonite and natural cellulose. The wall cancer production inhibiting material according to claim 1, wherein the modified montmorillonite is a montmorillonite having a relatively high layer spacing than the unmodified montmorillonite. The wall cancer production inhibiting material according to claim 1 or 2, wherein the content ratio of the natural cellulose is between 90 and 10% by weight; and the ratio of the montmorillonite is from 10 to 90% by weight. The wall cancer production inhibiting material according to claim 1 or 2, wherein the natural cellulose is selected from the group consisting of cellulose, methyl cellulose, ethyl cellulose, cellulose acetate, and hydroxyethyl cellulose. a group of its blends. The wall cancer production inhibiting material according to claim 4, wherein the modified montmorillonite is a modified montmorillonite which is polymerized with an organic modifier to cause a layer spacing expansion. The wall cancer production inhibiting material according to claim 5, wherein the layer spacing of the modified montmorillonite is 40A±10A. A method for producing a wall cancer production inhibiting material, the process step comprising: physically or chemically modifying a montmorillonite to produce a modified montmorillonite having a relatively wide layer spacing; taking a natural cellulose to a specific The ratio is mixed or polymerized with the modified montmorillonite in an aqueous phase environment. The method for producing a wall cancer production inhibiting material according to the seventh aspect of the invention, wherein the montmorillonite first modified the surface of the montmorillonite with a cationic surfactant, and then the montmorillonite and the montmorillonite The organic modifier is polymerized to form the modified montmorillonite having an expanded layer spacing. The method for producing a wall cancer production inhibiting material according to claim 7 or 8, wherein the cationic surfactant is cetyltrimethylammonium bromide, and the organic modifier is selected from the group consisting of a group consisting of methyl acrylate, styrene, and mixtures or polymers thereof; the natural cellulose is selected from the group consisting of cellulose, methyl cellulose, ethyl cellulose, cellulose acetate, and hydroxyethyl ethyl cellulose. a group of primes and their mixtures.
