Preparation method for reed fiber particle board

Abstract

The invention discloses a preparation method for reed fiber particle board. The preparation method comprises the following steps: cutting a reed raw material by using a circular sawing machine to prepare stem-shaped reeds with certain sizes; cutting the material by using a reed cutting machine, wherein one part of the cut material is cooked and softened to obtain the reed fibers, and the other part of the cut material crushed again to obtain fine reed shavings; respectively applying different resin adhesives to the reed fibers and the shavings, and drying, air-sorting and paving to form three-layer or multi-layer structural board blank; pre-pressing the three-layer or multi-layer structural board blank into a continuous flat-pressing hot press to press and produce the environment-friendly reed fiber particle board. The preparation method has the advantages that the influence of a wax layer on the surface of a reed on gluing performance is reduced to the greatest extent by graded pavement treatment; the production cost of the reed fiber particle board prepared by the process is moderate; both the physical and chemical properties of the reed fiber particle board meet related national standard requirements; the free formaldehyde release amount reaches the level-E1 standard requirement. According to the preparation method, reed resources of a wet land are fully utilized; the source of production raw materials of artificial boards is enlarged; the requirements on building resource-saving and environment-friendly society of China are met.

Description

technical field [0001] The invention belongs to the technical field of non-wood plant wood-based board production, and specifically relates to a new production process for making fiber particle boards by using grasses—reeds. Background technique [0002] Phragmites reed is a perennial tall herbaceous plant of the Gramineae family. It is widely distributed all over the world. It is an important wetland species widely distributed in the world. It is a highly differentiated morphologically differentiated species of meadow and wetland vegetation. High ecological and socioeconomic value, my country's reed resources are rich, widely distributed and concentrated, and now there are 14 main reed producing areas nationwide (Shandong Province is one of them, and Dongying City, Shandong Province has 500,000 mu of natural reed grassland , the annual output of high-quality reed is more than one hundred million kilograms), and the area of ​​reed is 1.3×106hm 2 Above, the economic value and ...

AI Technical Summary

Problems solved by technology

[0003] The reed fiber is long, and its aspect ratio and wall thickness to diameter ratio are within the range of excellent fiber materials, but its epidermis has a waxy layer, which contains non-polar silicon-containing substances and fatty substances. The urea-formaldehyde resin glue has poor wettability to the wax layer, and poor bonding performance to the reed wood-based panel
