Method for improving color difference of artificial marble

The invention discloses a method for improving color difference of artificial marble. The method comprises the following steps: (1) fully stirring calcium carbonate powder, auxiliary agents, kaolin and an inorganic binder in a stirrer to obtain a mixture a; (2) adding water into the mixture a prepared in the step (1), and performing stirring and mixing to prepare a mixture b; (3) putting the mixture b prepared in the step (2) into a material distributing machine; and (4) uniformly distributing the mixture b in a mold by using the material distributing machine, and carrying out vacuum pumping and compression molding by using a pressing machine to obtain an artificial stone product, thereby completing improvement of the color difference of the artificial marble. Under the condition of the same production environment, an auxiliary agent a, an auxiliary agent b and an auxiliary agent c are added and can be stably combined with the calcium carbonate powder and the like under the synergistic cooperation of the thre
