[0002] Wooden flooring includes six categories: solid wood flooring, laminate flooring, solid wood composite flooring, multi-layer composite flooring, bamboo flooring and cork flooring, as well as emerging wood-plastic flooring. No matter what kind of wood flooring, it is the most basic for wood flooring All substrates start with the selection of raw materials. Wooden flooring has become the most popular flooring material due to its excellent use effect, practicality and durability. The area is constantly shrinking, the environment is seriously deteriorating, and the wood is discarded or burned or left idle after use, resulting in a serious waste of resources. Such waste wood loses the space for reuse

Embodiment 1

[0039] Embodiment 1, discarded Chinese fir

[0040]An environment-friendly wooden floor prepared based on waste wood, including waste Chinese fir treatment process and environment-friendly wood floor molding process, wherein the waste Chinese fir treatment process includes the following steps:

[0041] Step 1. Classification: the waste wood is judged by the characteristics of the Chinese fir in the structure, and the Chinese fir is classified and placed;

[0042] Step 2. Remove impurities: The impurities on the discarded fir include iron nails, paint surface and plastic buckle. The iron nails and plastic buckle are removed by screwing and crushing the wood, and the paint surface is removed by sharpening 1-3mm;

[0043] Step 3. Axial cutting: place the discarded fir in the axial direction, and have a cutting tool to cut the fir axially, so that the cross section of the fir is within 20×20mm;

[0044] Step 4. Air knife derotation: Use an air knife nozzle with an aperture of 1mm...

Embodiment 2

[0065] Embodiment 2, discarded pine wood

[0066] An environment-friendly wood floor prepared based on waste wood, including waste pine wood treatment process and environment-friendly wood floor molding process, differs from Example 1 in that it is kept at about 100°C for 20 minutes in ultra-high temperature sterilization, and then the temperature is raised to 320°C. Keep the temperature for 20 hours and take it out; in step A, it takes 3 hours to cook the pine wood, and in step B, the pine wood is soaked in nitric acid solution for 15 minutes; The temperature of the box is maintained at 70°C for 1 hour; the pressure in step S4 is 4 MPa, and the hot pressing is continued for 60 seconds; the speed of the mixer in step S3 is 10 r / min.

Embodiment 3

[0067] Embodiment 3, waste poplar

[0068] An environment-friendly wooden floor prepared based on waste wood, including waste poplar wood treatment process and environment-friendly wood floor molding process, the difference from Example 1 is that it is kept at about 100°C for 13 minutes in ultra-high temperature sterilization, and then the temperature is raised to 280°C , keep the temperature for 16 hours and take it out; in step A, it takes 3 hours to cook the poplar, and in step B, the poplar is soaked in nitric acid solution for 15 minutes; The temperature of the two temperature boxes is kept at 75° C. for 1 hour; the pressure in step S4 is 3.2 MPa, and the hot pressing is continued for 58 seconds; the speed of the mixer in step S3 is 12 r / min.

Abstract

The invention discloses an environment-friendly wood floor based on waste wood. A preparation method of the environment-friendly wood floor comprises a waste wood treatment technology and an environment-friendly wood floor moulding technology, wherein the waste wood treatment technology comprises the steps of classifying, impurity removal, axial cutting, rot removal with air blades, ultrahigh temperature sterilization, axial crushing, fiber isolating, drying and storing; the environment-friendly wood floor moulding technology comprises the steps of fiber screening, low-pressure glue spraying in air, stirring, high-temperature high-pressure moulding, membrane laminating and cutting. According to the environment-friendly wood floor based on waste wood, first, the waste wood is classified, then rotten parts are removed, wood fibers are isolated so that the isolated wood fibers can have different levels, the wood fibers are sufficiently utilized, and thus secondary waste cannot be caused;furthermore, through low-pressure glue spraying in air, fibers which are completely wrapped with glue are obtained, possible defects of fiber damage on the waste wood are overcome through artificial protection, and the function of the high-strength wood floor is achieved.

Description

technical field [0001] The invention relates to the technical field of reuse of waste wood, in particular to a molding process of wood floors, and more specifically to an environment-friendly wood floor prepared based on waste wood. Background technique [0002] Wooden flooring includes six categories: solid wood flooring, laminate flooring, solid wood composite flooring, multi-layer composite flooring, bamboo flooring and cork flooring, as well as emerging wood-plastic flooring. No matter what kind of wood flooring, it is the most basic for wood flooring All substrates start with the selection of raw materials. Wooden flooring has become the most popular flooring material due to its excellent use effect, practicality and durability. The area is constantly shrinking, the environment is seriously deteriorating, and the wood is discarded or burned or left unused after use, resulting in a serious waste of resources. Such discarded wood loses the space for reuse. [0003] Commo...
