[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a composite bathroom cabinet material and its processing technology. Example 1

[0034] Combination Figure 1-5 As shown, the present invention provides a processing technology for a composite bathroom cabinet material, the processing technology including the following processing steps:

[0035] S1: Take several sets of cut and shaped raw wood boards 1, and use a multi-blade saw to cut a 45-60 degree groove along the side of the raw wood board 1 with an up-and-down staggered sawing method. The groove width is 3-3.8cm. This completes the bevel sawing. The initial cutting of the raw wood board 1 is completed to form a structure that is easy to assemble. At the same time, the up-and-down staggered sawing is used to break the internal stress and form an internal balance.

[0036] S2: Place the log 1 after the bevel sawing in a constant temperature room and place it evenly and flat. Keep it in an environment with a temperature of 40-45℃ and a humidity of 48-50%RH for 4-12 hours to further eliminate internal stress, avoid deformation in later processing, and increase the stability of the board and reduce the amount of deformation.

[0037] S3: Take two log boards 1, offset by 1.5mm, and splice them together. Use glue to bond them together. When splicing, the diagonal angles are opposite, resulting in a set of log mechanical boards. The staggered arrangement achieves a toothed interlocking structure, which improves the stability of the log boards 1 after they are joined together.

[0038] S4: Take two groups of log mechanical boards, adhesively and transversely fix three groups of multi-layer boards 2 on the sides of the two groups of log mechanical boards, and then adhesively and longitudinally bond two groups of multi-layer boards 2 on the sides of the two groups of log mechanical boards to form a "day" shape, obtaining the cabinet material substrate;

[0039] S5: Take the solid wood grid board 3 for milling. The width of the milled groove is 4 - 6 mm, and the depth is 2 - 4 mm. Put it into a constant temperature room for equilibration, and place it for 6 - 24 h in an environment with a temperature of 40 - 45 °C and a humidity of 48 - 50% RH; Use the constant temperature room for equilibration to prevent deformation of the solid wood grid board 3 after milling;

[0040] S6: Take the equilibrated solid wood grid board 3 and the single-sided veneer density board 4 with a thickness of 2 - 4 mm, and adhesively and fixedly attach them to the upper and lower sides of the cabinet material substrate respectively. The upper solid wood grid board 3 and the bottom density board 4 both bend outwards, and are adhesively attached on one side to achieve inner layer balance; Optimize the bonding process, make the bending direction of the melamine face the melamine surface bonding part, so as to keep balance with the solid wood bending direction in the later stage and form a more stable structural effect.

[0041] S7: Finally, use a precision saw for trimming and paste wood veneer of the same size to obtain the composite bathroom cabinet material.

[0042] Preferably, the original wood board 1 is made of pine wood board.

[0043] Preferably, the multi-layer board 2 is a multi-layer board arranged vertically.

[0044] Preferably, in step S5, the width of the milled groove is 5 mm and the depth is 3 mm. Optimize the size specification of the milled groove. Considering the characteristics of the bathroom cabinet door product, the overall specification of its door panel is relatively small. Optimize the size specification of the milled groove to avoid large shrinkage of the solid wood grille and deformation.

[0045] Preferably, the density board 4 is a single-sided melamine-coated density board.

[0046] Preferably, in step S2 and step S5, the temperature of the constant temperature room is 43 °C and the humidity is 49% RH.
