The invention provides a novel artificial marble and manufacturing method thereof. The novel artificial marble comprises a body layer composed of a filling material and a resin adhesive material, a coating layer containing titanium dioxide or a mixed coating comprising titanium dioxide. The surface of the novel artificial marble has a titanium dioxide coating film or a coating containing titanium dioxide or the mixed coating comprising titanium dioxide, so that the artificial marble has a self-cleaning function, and can greatly reduce cost for maintaining clean when the artificial marble is used as a building material. Due to the excellent ultraviolet absorption function of titanium dioxide, decomposition of the component materials of the artificial marble can be effectively prevented; mechanical performance of the artificial marble can be maintained; and fractures/cracks can be prevented from appearance. The particles or powder of the main raw materials of the artificial marble are inorganic waste materials of buildings and livings and even waste materials of the artificial marble, thereby reducing cost, decreasing resource waste and protecting the environment.
