Embodiment 1

[0027] The raw materials and mass fractions used in the preparation of a waste paper / high-density polyethylene luminescent composite material are as follows:

[0028]

[0029]

[0030] (1) Put the recovered waste newspapers into a shredder and crush them, the size of the fragments is 5*20mm, and then mix the newspapers with a 1% sodium hydroxide solution, and the mass ratio of the two mixtures is 1:10. Stir at a speed of 20r / min until the newspaper is completely submerged, filter after reacting for 8 minutes, and dry in a drying oven at a drying temperature of 90°C and a drying time of 24 hours. The dried waste paper is pulverized with a cutting grinder to obtain 40-80 mesh paper powder.

[0031] (2) Put paper powder, high-density polyethylene and other raw materials into a high-speed mixer according to the proportion and mix them evenly. The mixing temperature is 120°C and the mixing time is 30 minutes.

[0032] (3) Extrude and granulate the mixed material with a twin-...

Embodiment 2

Abstract

The invention relates to a composite, and provides a waste paper / high-density polyethylene luminescent composite and a preparation method thereof. A long-persistence luminescent material subjected to organic modification is adopted as luminescent pigment, the long-persistence luminescent material, pretreated waste paper fiber powder, high-density polyethylene, a coupling agent, a processing agent and the like are subjected to blending extrusion, and the luminescent wood-plastic composite is obtained. According to the waste paper / high-density polyethylene luminescent composite and the preparation method thereof, the comprehensive utilization level of waste resources is greatly improved, and environmental pollution caused by treatment of waste resources is greatly reduced; compared with a traditional board and a traditional wood-plastic composite, the luminescent composite is easy to process, low in cost, wide in raw material source, environmentally friendly, free of pollution and the like; besides, by adding the luminescent material, the advantages of practicability, attractiveness, safety and the like of the luminescent composite are improved, and based on an existing wood-plastic board production process, the luminescent composite is a wood-plastic board very suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of wood-plastic composite materials, and in particular relates to a waste paper / high-density polyethylene luminous composite material and a preparation method thereof. Background technique [0002] Paper is widely used in our life, and paper fiber, as a kind of natural fiber, has been paid more and more attention by people, but the recycling rate of paper products is very low, and most of them are used for recycling to produce lower-grade paper Products, the recycling process is complicated, but the economic benefits are very low, which is not conducive to the rational utilization of resources. Using waste paper instead of wood fibers to make wood-plastic composite materials does not require a deinking process, has low recycling costs, can be filled in large quantities, has a wide range of applications, high economic value, and has a good application prospect. [0003] Wood-plastic composite material is a polymer mat...
