specific Embodiment approach 1

[0016] Specific embodiment one: In this embodiment, a photochromic wood-plastic composite material is structured by a photoluminescent surface layer and a polyolefin wood-plastic composite substrate.

[0017] The photochromic wood-plastic composite material prepared by this embodiment can cause photochromic phenomena in sunlight, ultraviolet light and well-lit indoors. See attached figure 1 And figure 2 .

specific Embodiment approach 2

[0018] Specific embodiment two: this embodiment is different from specific embodiment one in that the photoluminescent surface layer is prepared by mixing photoluminescence powder and polypropylene resin in a certain mass ratio and then forming. Others are the same as the first embodiment.

specific Embodiment approach 3

[0019] Specific embodiment three: This embodiment is different from one of specific embodiments one or two in that the polyolefin wood-plastic composite material base material is made of polyolefin plastic, compatibilizer, lubricant and wood powder in a certain mass ratio It is prepared by mixing and molding; the polyolefin plastic is one of polyethylene and polypropylene; the compatibilizer is one of maleic anhydride grafted polyethylene and maleic anhydride grafted polypropylene; The lubricant is one of paraffin wax, polyethylene wax, and polypropylene wax; the wood flour mesh number is 20-120 mesh. Others are the same as the first or second embodiment.

Abstract

The invention relates to the technical field of wood-plastic composites, and in particular relates to a photochromic wood-plastic composite and a preparation method thereof. The invention discloses a photochromic wood-plastic composite, and a photochromic surface layer is pasted on and covers the surface of a base material. The wood-plastic composite provided by the invention has a photochromic function, is simple in preparation method and can be used for decoration, identification, an advertising material, a building external wall and the like, and application range of the wood-plastic composite is expanded.

Description

Technical field [0001] The invention relates to a photochromic wood-plastic composite material and a preparation method thereof. [0002] technical background [0003] Wood-plastic composite material has been a commercial product and has formed a related manufacturing industry, mainly used in the packaging industry, construction industry and automotive and aircraft accessories. Although the scope of application of wood-plastic composites continues to expand, they have never been applied in indoor and surface decoration. This is because the surface texture and visual comfort of wood-plastic composites are not good enough, so in recent years, many researches on the functional improvement of wood-plastic composites have been carried out. [0004] The purpose of the functional improvement of wood-plastic composites is to give them a certain new function that they did not originally possess and to expand the application range of wood-plastic composites. Changing the surface properties of...
