The invention discloses an application of sinkaline used as a B type alkali copper chloride anticaking agent. The invention discovers that B type alkali copper chloride reacts with the sinkaline under the condition of sufficient stirring by adding the sinkaline to the B type alkali copper chloride, and the crystalline structure of the B type alkali copper chloride tends to be stable so that the B type alkali copper chloride does not cake any more and the defect of use influence of the B type alkali copper chloride due to caking is overcome. By adding the sinkaline to the B type alkali copper chloride, the B type alkali copper chloride has better stability and can be stored for a long time without caking; and the B type alkali copper chloride in which the sinkaline is added can be used as an animal feed additive.
