Abstract
An outdoor laminate floor includes a substrate made from PVC foaming and a wear-resistant, anti-aging covering film that is adhered to the surface of the substrate. The covering film overlays the surface of the substrate after being adhered by hot glue. The covering film is a modified weather-resistant polymeric film. In this way, the outdoor laminate floor has a simple and compact structure, and solid wood is replaced with the substrate and the covering film, which not only protects environment by reducing the use of solid wood, but also reduces the manufacturing cost and improves the competitive edge on the market, owing to the low-cost substrate and covering film.
