摘要：NOVELTY - Composite material comprises 68-90 wt.% of percarbonate, 0.5-12 wt.% of accelerating agent, 5-14 wt.% of isolation material and 0.05-6 wt.% of envelop agent, where: the percarbonate is oxidizable metal peroxide such as sodium sulfate, sodium carbonate, magnesium peroxide or calcium peroxide; the accelerator is a enzyme with a phosphate; the isolated material is 60-200 meshes of fly ash clay; and the envelope is lauric acid, isopropyl palmitate, acid or alcohol. USE - The composite material is useful for restoring environment water body such as improving nutritional requirement and water pollution degree and promoting indigenous microorganism growth for releasing oxygen(claimed). ADVANTAGE - The composite material improves the water self-purification capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the composite material, comprising taking a certain amount of envelope agent into pure chloroform or carbon tetrachloride for chemically react at not less than 10-65 degrees C, adding certain amount of the isolation material, clockwise or counter-clockwise stirring for 5-30 minutes, pressing to obtain grid-shaped, plum blossom or annual shaped envelope slot, adding certain proportion of the percarbonate and accelerant to fill into the envelope slot, and then pressing to obtain the end product with different shapes, and then drying under the protection of nitrogen, and recycling organic solvent.
