Problems solved by technology

Although this patent application solves the above problems to a certain extent, however, due to the thin thickness of the surface plate (3-5mm), after a certain period of use, the surface plate wears and becomes thinner, or even wears through so that the upper veneer appears. affect the appearance; moreover, since the peeled core material is first processed into a square plate, and then cross-cut into the plate, although the difficulty of the subsequent assembly process is reduced, on the one hand, the diameter of the log is stricter, and at the same time the production The waste generated in the process is more, resulting in the waste of wood, on the other hand, it destroys the natural texture of the tree and reduces the aesthetic feeling of the floor

Embodiment 1

[0027] Process log crosscut parquet as follows:

[0028] (a) Cross-cut blanking

[0029] Select the log trunks and branches with a diameter of 5 to 30 cm to remove the bark and take the core, and cut the core into a thickness of 2 cm to obtain an irregularly shaped circular plate;

[0030] (b) drying

[0031] Put the irregularly shaped discs into a wood dryer, first dry the irregularly shaped discs to a moisture content of 12.5% ​​at a temperature of 40°C and a relative humidity of 72%, and then dry them at a temperature of 40°C. Dry the disc with irregular shape at low temperature to a moisture content of 9%. The drying time should be at least 12 hours a day (if the wood to be dried has a low density, which is commonly referred to as wood that is not easy to crack, it can be dried for one day, that is, 24 hours).

[0032] (c) Assembly

[0033] Place a plurality of irregularly shaped discs dried in step (b) on an operation table with a flat surface, splice adjacent irregul...

Embodiment 2

[0040] The processing technology is the same as that of Example 1, except that the jigsaw glue used in step (c) is self-made, and the preparation method is as follows: wood glue powder, sawdust, and water are mixed in a ratio of 3:2:1 by weight, and the sawdust is the age of the tree. It is made of ginkgo tree wood that is more than 100 years old, and the particle size of sawdust is less than 100 mesh.

[0041] After passing the strength test, it shows that the adhesive force of self-made jigsaw glue is greater than that of purchased jigsaw glue. Moreover, after the glue is solidified, its color is consistent with that of the irregularly shaped circular plate, which will not affect the appearance of the floor.

Embodiment 3

[0043] The processing technology is the same as that of Example 2, except that in step (c), the assembled planks are placed on an extruder to extrude horizontally and vertically, so that the combination between the irregularly shaped circular plates is tighter.

Abstract

The invention discloses processing technology for a log crosscutting wood floor, which comprises the steps of: (a) crosscutting blanking; (b) drying; (c) assembly; (d) surface treatment; and (e) cutting and slotting. The log crosscutting wood floor only has one layer, a thickness of between 2 and 3cm, and high strength and good wear resistance; moreover, the processing technology directly crosscuts a peeled core material and then assembles, retains the natural texture of trees to a great extent, has strong aesthetic feeling due to the fact that joints are also of arc shapes, and meets the demand of high-grade users; in addition, the processing technology has low requirement on the diameters of trunks or branches or roots of logs, almost does not generate waste materials during the processing, and helps to save the timber.

Description

technical field [0001] The invention relates to a wooden floor, in particular to a processing technology for log cross-cut wooden floor. Background technique [0002] At present, ordinary solid wood flooring is assembled from planks sawn longitudinally by logs. The length of the floor is 400-2300mm, the width is 80-270mm, and the thickness is 8-12mm. Because the floor adopts slitting, on the one hand, the stress of the board is relatively large, and it is easy to deform during use; on the other hand, the pattern of the produced floor is traditional and universal, which cannot meet the needs of high-end users. [0003] In order to solve the above problems, Chinese patent CN101302887 on November 12, 2008 disclosed a log cross-cut three-dimensional solid wood composite floor and its preparation method. Wherein the surface board is a spliced ​​cross-cut hardwood board, and the preparation method is that the materials are dried separately and then hot-pressed and bonded. Althou...
