▎ 摘  要

NOVELTY - Functional polymer molded article, prepared by molding antimicrobial composition comprising 0.05-60 pts. wt. antibacterial agent and 40-99.95 pts. wt. base resin, and antibacterial agent is mesophilic calcium powder, ion exchange calcium powder, hydrophilic ceramic powder, hydrophobic powder and/or antibacterial polymer, drying mesophilic calcium powder at 100-150 degrees C for 12-36 hours after washing calcium agent with water, crushing dried calcium agent to prepare a primary pulverized product, primarily heating primary pulverized product at 150-300 degrees C for 1-6 hours, and then secondarily heating at 300-500 degrees C for 1-12 hours, and performing mesophilic calcination through tertiary heating at 500-900 degrees C; mesophilized primary pulverized product is prepared by secondary pulverizing the primary pulverized product that has been calcined at medium temperature to have an average particle size of 0.5-50 mu m, where calcium agent comprises at least one selected of shells and eggshells, is claimed. USE - The functional polymer molded article is useful for packaging of foods and medicines. ADVANTAGE - The article exhibits excellent antibacterial activity and antifungal activity, has excellent deodorizing performance; can be reused because it is easy to recover, can safely store water for a long time, prevents growth of microorganisms when introduced in a cosmetic container with natural cosmetics, can prevent deterioration of cosmetics; is environmentally friendly; improves antibacterial and antifungal activity and deodorizing performance; is easy to carry and simple to use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing an antibacterial molded article. DESCRIPTION OF DRAWING(S) - The drawing shows a process diagram showing a method of manufacturing a functional polymer molded article (Drawing includes non-English language text).
