specific Embodiment approach 1

[0010] Specific implementation mode one: combine figure 1 Describe this embodiment, the lightweight wood-plastic composite board with a woody surface in this embodiment includes a foamed wood-plastic composite material layer 3, and the lightweight wood-plastic composite board with a woody surface also includes an upper veneer 1 and a lower veneer 2. The upper veneer 1 and the lower veneer 2 are arranged up and down, and the foamed wood-plastic composite material layer 3 is arranged between the upper veneer 1 and the lower veneer 2, and the foamed wood-plastic composite material layer 3 and the upper veneer 1 It is fixedly connected with the lower veneer 2.

[0011] In this embodiment, a layer of veneer is pasted on the upper and lower surfaces of the foamed wood-plastic composite material layer, so that the surface of the formed board has a woody feel and is more acceptable to people. The foamed wood-plastic composite material layer itself has low strength and light weight, a...

specific Embodiment approach 2

[0012] Embodiment 2: This embodiment is different from Embodiment 1 in that: the thickness of the upper veneer 1 and the lower veneer 2 is 1-3 mm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the thickness of the foamed wood-plastic composite material layer 3 is 6-12 mm. Others are the same as in the first or second embodiment.

Abstract

The invention provides a preparation method of a lightweight wood-plastic composite plate with a wood texture surface, and relates to a preparation method of a wood-plastic composite plate. In the prior art, the wood-plastic composite material has high density, transportation and use of the wood-plastic composite material are not convenient, and the surface of the wood-plastic composite material lacks the wood texture. The purpose of the present invention is to solve the problems in the prior art. The wood-plastic composite plate comprises a foamed wood-plastic composite material layer, and further comprises an upper thin wood plate and a lower thin wood plate, wherein the foamed wood-plastic composite material layer is arranged between the upper thin wood plate and the lower thin wood plate, and the foamed wood-plastic composite material layer forms fixed connections with the upper thin wood plate and the lower thin wood plate. The preparation method comprises: mixing plant fiber powder, thermoplastic powder, a coupling agent and an AC foaming agent; paving the lower thin wood plate in a mold, and then paving the foamed wood-plastic composite material layer; covering the upper thin wood plate on the foamed wood-plastic composite material layer, and covering an upper cover plate on the upper thin wood plate; placing the mold in a hot pressing machine to carry out hot pressing; carrying out shaping and sanding to obtain the wood-plastic composite plate. The wood-plastic composite plate of the present invention has low density and high bending strength, and is applicable for furniture manufacturing, architectural decorations, transportations and other fields.

Description

technical field [0001] The invention relates to a preparation method of a wood-plastic composite board. Background technique [0002] Wood-plastic composites (WPC for short) are materials or products that are compounded or further processed by one or more cellulose materials and one or more thermoplastics through plastic processing technology. Moisture-proof, partially degradable, less environmental pollution, low cost, low water absorption, excellent mechanical properties, anti-aging, good dimensional stability, no cracking, etc., and has a processability similar to wood. It is more and more widely used in industries such as construction, automobile, indoor and outdoor flooring and decorative materials. However, wood-plastic composites have a high density (0.9-1.05g / cm 3 ), transportation and use are inconvenient; most of them adopt extrusion processing technology, although the products can be formed at one time, but the width is limited (usually below 150cm, a few produc...
