The invention discloses environment-friendly plastics and relates to the technical field of environmental protection. The environment-friendly plastics contain the following ingredients in percentage by mass: 3-4 parts of vinyl trimethoxysilane, 1-4 parts of phenyl silicone oil, 2-3 parts of sodium bisulfite, 6-7 parts of activated aluminum hydroxide, 3-4 parts of chopped asbestos fibers, 4-5 parts of polylactic acid, 3-5 parts of maleic anhydride modified polyethylene, 1-3 parts of maleic anhydride grafted solubilizer and 6-7 parts of polycaprolactone. The environment-friendly plastics are prepared from materials such as vinyl trimethoxysilane, phenyl silicone oil, sodium bisulfite, activated aluminum hydroxide and the like; through optimizing the proportioning ratio of all the ingredients, the prepared environment-friendly plastics are good in environment-friendly effect, high in strength, good in toughness and good in heat resistance; and the environment-friendly plastics are good in stability, thereby being capable of better protecting environment.
