Coated copper sulfate for feedand preparation method thereof

The invention provides coated copper sulfate for feed and a preparation method thereof, the coated copper sulfate for the feed comprises the following raw material components in parts by weight: 19-35 parts of copper sulfate, 22.8-61.3 parts of granular silicon dioxide, 20-60 parts of a coating material and 38-87.5 parts of water, and the coating material comprises vegetable wax and a surfactant; the preparation method of the coated copper sulfate for the feed comprises the following steps: preparing a copper sulfate solution; the granular silicon dioxide is added into the copper sulfate solution and uniformly mixed, so that the copper sulfate solution is completely adsorbed by the granular silicon dioxide; preparing pellet cores; and preparing the coating copper sulfate for the feed. The coated copper sulfate prepared by the invention can realize complete coating of copper sulfate by a coating material and can ensure long-term isolation of copper sulfate in the coated copper sulfate from other substances in
