Problems solved by technology

[0002] Dead wood has been considered "uncarvable" since ancient times. However, dead wood has a unique surface mechanism and a retro aesthetic. Although there are still sculptors who use dead wood to prepare and carve various exquisite products, even if the carver is careful when carving, there are still dead wood. In case of breakage or slag falling due to engraving, it is difficult for the engraver to engrave successfully, and the discard rate is high

Embodiment 1

[0057] Embodiment 1 compacts the rotten plank separately

[0058] This embodiment provides a kind of dead wood compacted material, the preparation method of this dead wood compacted material comprises the following steps:

[0059] a. High-temperature and high-humidity treatment: place the rotten wood boards in the drying cellar for heating and humidification, adjust the relative humidity in the drying cellar to 50%, the temperature to 50°C, the heating and humidification time to 3 hours, and then adjust the relative humidity in the drying cellar to 80% , the temperature is 44°C, the heating and humidification time is 20 minutes, and the high-temperature and high-humidity treatment rotten wood board is obtained;

[0060] b. Drying treatment: reduce the rotten wood boards treated with high temperature and high humidity to room temperature, equilibrate at room temperature for 12, then place the dried rotten wood boards in a drying cellar, heat up to 120°C, and keep them warm for ...

Abstract

The invention relates to a rotten wood compacted material based on a high-frequency no-adhesive compacting technology and a method. The rotten wood compacted material is mainly prepared from rotten wood plates with the endwise vein bending strength being smaller than 25 MPa, transverse vein bending strength being smaller than 8 MPa, the flat plane tensile intensity being smaller than 0.4 MPa, theheat-resistant dimension stability being greater than 8.00 percent and wet-resistant dimension stability being greater than 5.00 percent through high frequency heating pressing. The endwise vein bending strength of the rotten wood compacted material is higher than 85 MPa; the transverse vein bending strength is higher than 30 MPa; the flat plane tensile intensity is greater than 1.5 MPa; the heat-resistant dimension stability is smaller than 1.5 percent; the wet-resistant stability is smaller than 0.8 percent. The compacted material provided by the invention has the unique color and veins, hasthe rich attractive feeling; when the compacted material is used for engraving, the engraving finished product rate is high; the rejection rate is very low.

Description

technical field [0001] The invention belongs to the technical field of wood board processing, in particular to a rotten wood compaction material and method based on high-frequency glue-free compaction technology. Background technique [0002] Dead wood has been considered "uncarvable" since ancient times. However, dead wood has a unique surface mechanism and a retro aesthetic. Although there are still sculptors who use dead wood to prepare and carve various exquisite products, even if the carver is careful when carving, there are still dead wood. In the case of breakage or slag falling due to carving, it is difficult for the carver to carve successfully, and the discard rate is high. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for preparing deadwood compacted materials based on high-frequency (ie high-frequency) glue-free compaction technology. The compacted materials prepared by this method hav...
