Abstract
The invention discloses a carried antioxygen and a preparation method thereof. The carried antioxygen is composed of nano silicon dioxide and antioxygen. The preparation method comprises fully mixing the antioxygen and the nano silicon dioxide inside a solvent, removing the solvent and performing drying and crushing. By taking the nano silicon dioxide as the carrier, the prepared carried antioxygen can obtain relatively high dispersity in a matrix; compared with the antioxygen, the nano silicon dioxide is low in cost, and when serving as the carrier, can achieve identical antioxidant effects and meanwhile reduce consumption of the antioxygen, thereby reducing the production cost of materials on balance; when serving the carrier and applied to polymers such as PP (polypropylene) and PE (polyethylene), the nano silicon dioxide can facilitate production of porous antioxidant membranes.
Description
Technical field
The present invention relates to a kind of loading type oxidation inhibitor and preparation method thereof.
