摘要： Disclosed is a composite floor, comprising a wear-resistant layer, a polyvinyl chloride patterned fabric layer, a base material layer, a balance layer, and a muting layer that are sequentially arranged, the wear-resistant layer being a melamine wear-resistant paper layer. The composite floor has a clear and vivid pattern, and the wear and scratch resistance is far better than that of a conventional floor, the manufacturing process comprising laying, hot pressing, demolding and tempering steps. The manufacturing process has simple steps, and the obtained composite floor has high dimensional stability and good wear and scratch resistance.
