Ammonia removal agent used for rubber and plastic foaming product and preparation method thereof

The invention discloses an ammonia removal agent used for a rubber and plastic foaming product and a preparation method thereof. The ammonia removal agent comprises, by weight, 60-65 parts of anhydrous aluminum sulfate, 2-3 parts of surface modification agents and 32-37 parts of solvent. The method includes the steps that the surface modification agents and the solvent are added into a container according to the proportion and then stirred; in the stirring process, the anhydrous aluminum sulfate is added to be dissolved into even paste, so that the ammonia removal agent is obtained. The ammonia removal agent is added into EVA and can rapidly disperse and react with ammonia radicals, in this way, the ammonia radicals and ammonia are effectively removed, and conditions for forming formamide can be broken before the formamide is formed.
