Abstract

The invention discloses a laminate flooring capable of removing methanol through negative ions. The laminate flooring is sequentially composed of a balance layer, a base material layer, a functional coating layer, a decorating layer and an abrasion resistance layer from bottom to top, wherein the functional coating layer, the decorating layer and the abrasion resistance layer are composited on the surface of the base material layer. The functional coating layer composited on the surface of the base material layer is composed of water based coating, negative ion powder and methanol capture agents. The invention further discloses a manufacturing method of the laminate flooring capable of removing the methanol through the negative ions. According to the laminate flooring capable of removing the methanol through the negative ions, the methanol capture agents have the effects of methanol adsorbing, fixing and degrading, and have a good removing effect on the methanol in surrounding materials. The negative ion powder has the functions of generating the negative ions constantly, releasing far infrared rays, sterilizing and inhibiting bacteria, and the negative ions released by the negative ion powder can conduct oxidative decomposition on the abnormal smell of the organic gas of the methanol and the like in the environment, so that the capacity of constant and permanent methanol removing of the methanol capture agents is improved.
