Problems solved by technology

[0003] However, the existing wood-plastic materials have a single style, and they are only studied in the production of processing technology. In the process of processing, the combination between wood and plastic is enhanced to produce composite materials with stronger stability and better plasticity. , to suit various environments
[0004] With the pursuit of materials, the application of wood-plastic and bamboo-plastic materials has been widely used in every corner of the city, but it has not improved the use value and ornamental value of wood-plastic materials: for example, the use of self-illumination function It has widened its application field and can be used for interior decoration, outdoor flooring and other facilities, especially in traffic roads, its use value is more obvious, and it can provide lighting or warning functions

Abstract

The invention relates to the technical field of preparation of fixed luminescent materials, specifically to a preparation method for a wood-plastic board capable of absorbing ultraviolet rays and emitting fluorescence. The wood-plastic board comprises the following materials: 15 to 18% of a core-layer material, 13 to 16% of a surface-layer material located on the surface of the core-layer material, 55 to 60% of wood powder, 1 to 4% of a fluorescent agent, 1 to 4% of a coupling agent and 0.2 to 0.5% of an antioxidant, with the balance being an auxiliary agent. The wood-plastic board prepared byusing the preparation method provided by the invention improves the decorative properties of a material, is broadened in application fields through the function of self-illumination, has long luminescence time, can be used for facilities like indoor decorations and outdoor floors, has more significant utilization value especially in the field of traffic roads, and can exert the effects of illumination, warning, etc.; and the surface of a finished wood-plastic board product has the strength and smoothness of co-extruded polyethylene, and has strong nail-holding force.

Description

technical field [0001] The invention relates to the technical field of fixed luminescent materials, in particular to a preparation method of a wood-plastic board capable of absorbing ultraviolet rays and emitting fluorescence. Background technique [0002] Wood-Plastic Composites (WPC) is a new type of composite material that has flourished in recent years at home and abroad. It refers to the use of polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesives. More than 50% of wood flour, rice husks, straws and other waste plant fibers are mixed into new wood materials, and then through extrusion, molding, injection molding and other plastic processing processes, the plates or profiles are produced. Mainly used in building materials, furniture, logistics packaging and other industries. The plastic and wood powder are mixed in a certain proportion and then hot-extruded to form the board, which is called extruded wood-plastic composite board. There...
