fifth, of the floor body blankPreparation: firstly, coating EPI glue on one surface of a surface plate 1 and a bottom plate 2; secondly, gluing the combined frame 4 in the fourth step to form a simulated solid wood floor blank; the dosage of the EPI glue is 180g/m2And the thickness of the surface plate 1 is required to be consistent with that of the bottom plate 6, so that an imitated solid wood floor blank 8 with the thickness of 18.4mm is obtained, and cold pressing is adopted, wherein the parameters during cold pressing are as follows: pressure: 12kgf/cm2And time: for 60 minutes.
Sixthly, manufacturing a finished floor body product: and E, sanding the two surfaces of the solid wood floor imitating blank manufactured in the step V, processing tenons and mortises at the two ends and the two sides of the floor body through a mortising machine, and finally processing the floor body through a coating process to obtain the floor body.
The performance tests of the existing solid wood floors and the floors manufactured in the first, second and third embodiments were performed (the valuable wood is maple, and the fast growing wood is poplar), as follows:
hardness of Expansion ratio Shrinkage rate Compressive strength (MPa)
Solid wood floor 1450 4.5％ 2.64％ 30
Example one 1433 2.5％ 1.44％ 45
Example two 1447 2.3％ 1.29％ 48
EXAMPLE III 1439 2.6％ 1.31％ 52
Wherein the hardness is jensen's hardness.
As can be seen from the table, compared with the existing solid wood floor, the simulated solid wood floor manufactured by the invention maintains higher hardness, and simultaneously has smaller expansion rate and shrinkage rate and high compressive strength.
On the basis of the above-described aspects, if various changes or modifications to the present invention are made without departing from the spirit and scope of the present invention, it is intended that the present invention also include these changes and modifications if they fall within the scope of the claims and the equivalent technical scope of the present invention.
