Problems solved by technology

However, at present, there are few reports on wood-plastic as a luminescent wood material. Usually, it is realized by inlaying luminescent materials on the surface of wood-plastic when cooking. The above method obviously has serious shortcomings in appearance, and the use effect is not ideal.

Abstract

A preparing method of a light-storage type luminescent wood-plastic composite is disclosed. The preparing method includes: (1) a step of preparing luminescence master batch, namely a step of blending 10-30 parts of light-storage type luminescent pigment, 60-90 parts of PA6, 1-5 parts of an oxidant and 2-5 parts of an anti-ultraviolet agent, and granulating on a granulator to obtain the luminescent master batch; and (2) a step of performing extrusion molding to prepare the luminescent wood-plastic composite, namely a step of adding the luminescent master batch prepared by the step (1) into a side extruder of a co-extrusion extruder, extruding to obtain a surface layer of the luminescent wood-plastic composite, adding a present wood-plastic granulating material into the main extruder of the co-extrusion extruder, and extruding to obtain a bottom layer of the luminescent wood-plastic composite. The surface layer with light storage capability and the bottom layer formed by extrusion of a common wood-plastic composite are integrated and moulded by an extrusion manner, so that the luminescent layer and the wood-plastic composite main body are perfectly integrated, and the luminescent wood-plastic composite has characteristics of beautiful and elegant appearance, long luminescence time and good using effects.

Description

technical field [0001] The invention relates to a method for preparing wood-plastic materials, in particular to a method for preparing light-storing luminous wood-plastic materials, which belongs to the technical field of wood-plastic materials preparation. Background technique [0002] The third generation of light-storing self-luminous materials came out in my country in the 1990s. Compared with the previous two generations of self-luminous materials, this material has significant advantages such as non-toxic and non-radioactive. The luminescence mechanism of this material is a microscopic physical process. Due to the characteristics of the rare earth material structure: the outer electrons of the atoms have the ability to transition from a low energy level to a high energy level under light conditions, and fall into the structural electron trap, thereby storing light. In the dark, electrons can return from a high energy level to a low level, thereby emitting light. This ...
