Method for preparation of

The manufacturing method of temperature sensing color changing floor boards relates to a manufacturing technique of floor boards. Floor boards are produced by the following procedures: the plain floor board is dyed with painting liquid containing temperature sensing color changing color masterbatch according to the conventional process, thus the temperature sensing color changing color masterbatch is obtained. The floor boards made by the method has the visual effect when the temperature changes which is demonstrated by color changing, when the floor boards sense the change of temperature; while when the temperature restores to the normal temperature and the color also returns. Therefore, the original artistic vein is maintained, which enhances the beauty; meanwhile, the color varies with the temperature grade. The method can be applied to floor boards made of solid wood, compound floe boards of solid wood (three or two layers), intensified compound floor boards, which not only preserves the original techniqu
