The present application relates to the technical field of floor manufacturing, and particularly relates to a non-
polyvinyl chloride wood-plastic plate with three-dimensional
wood grain and a preparation method and application thereof. The non-
polyvinyl chloride wood-plastic plate comprises a non-
polyvinyl chloride wood-plastic base layer containing
polyolefin resin with
surface energy not higher than 35 dynes / cm, and an
adhesive bottom attached to one side of the non-polyvinyl
chloride wood-plastic base layer and having
surface tension less than that of the
polyolefin resin. The non-polyvinyl
chloride wood-plastic plate further comprises a two-dimensional pattern layer, a three-dimensional wear-resistant layer and a top paint layer. The present application limits the
surface energy relationship between the
adhesive bottom and the non-polyvinyl
chloride wood-plastic base layer, thereby effectively preventing the non-polyvinyl chloride wood-plastic plate from peeling, warping and
cracking, and effectively improving the stability and durability of the plate. Meanwhile, the prepared non-polyvinyl chloride wood-plastic plate can realize the
environmental protection production and recycling of wood-plastic plates, and the visual and tactile three-dimensional
wood grain is closer to the real
wood grain.
