Fluorescent wood-plastic external wall board and preparation method thereof

Abstract

The invention relates to a fluorescent wood-plastic external wall board. Raw materials of the fluorescent wood-plastic external wall board further include a luminous pigment, the luminous pigment is prepared by directly and physically mixing a fluorescent material subjected to organic modification treatment and then performing forming through a fusing-plasticizing device and a mouth mold or is prepared by adopting the fluorescent material subjected to organic modification treatment as a fluorescent pigment, co-extruding and mixing the fluorescent pigment and a wood-plastic wall board, adding the mixture to a lateral extrusion machine of a coextrusion machine for coextrusion with the coextrusion machine and performing plasticizing, mixing and mouth mold forming. The invention further discloses a preparation method. By the adoption of the preparation method, a surface-layer luminous wood-plastic product uniform in color and luster, good in durability and having good luminous property can be prepared, and the effects of weak light indication, decoration and beautifying are played.

Description

technical field [0001] The invention relates to a wood-plastic wallboard and a preparation method thereof, in particular to a fluorescent wood-plastic exterior wallboard and a preparation method thereof, belonging to the technical field of wood-plastic composite materials. Background technique [0002] Due to its non-radioactive, energy-saving, and environmental-friendly features, fluorescent materials are used more and more in people's lives. At present, the main fields of its industrial application are in the field of plastics and coatings, and there are few reports in the field of wood-plastic composite materials. Chinese patent (CN 201410309580) obtains a luminescent masterbatch by blending and granulating light-storage luminescent pigments, PA6, oxidant, and anti-ultraviolet agent. WPC material.

AI Technical Summary

Problems solved by technology

However, in the preparation process of this method, there will be incompatibility problems when the luminescent pigment as an inorganic material is blended with the organic system, and the mechanical properties of the prepared luminescent plastic products will decrease sharply as the amount of luminescent powder added increases.

At the same time, during the mixing and plasticizing process, the contact and friction between the luminescent pigment and the metal devices inside the processing equipment will cause the luminescent pigment to turn black, which will seriously affect the luminous performance and gloss of the wood-plastic wallboard.
