Problems solved by technology

This production method is the mainstream method, but it has the following disadvantages: long order cycle, secondary processing is required, high cost, rough surface texture, difficult to control formaldehyde emission, generally only reach E1 level)
This method has the following disadvantages: the degree of deformation of the board cannot be controlled, the holes of the board cannot be controlled, there is no standard for the static bending strength of the board, there is no requirement for the thickness of the board, there is no filling for the wood conduit of the board, and the amount of formaldehyde released is unstable.

Embodiment 1

[0031] One: Material

[0032] ① Core board and long middle board: two layers of fast-growing eucalyptus wood core board (can be spliced) with length, width and thickness of 1270X2520X1.8mm + one layer of fast-growing eucalyptus wood long middle board of 2520x1270x1.7mm. (The thickness difference between the core board and the long middle board is not more than 0.3mm, usually between 0-0.3mm, and the thickness of the overall ingredients is 5.1-5.4mm)

[0033] ②Panel: Thickness 0.4mm-0.6mm, fine wood grain, good stability, high strength veneer (also known as veneer, such as mercerized wood, eucalyptus, Okoume, Terminalia, etc.)

[0034] ③Glue: (Tier Adhesive (Guangdong) Co., Ltd.) melamine modified urea-formaldehyde resin, which is required to meet the E0 standard, with a solid content greater than 55%, good aging performance, and glue strength and water resistance up to the second-class plywood standard.

[0035] Two. the preparation method described in the present embodiment ...

Abstract

The invention discloses a veneer special for a wood blade of a classical ceiling fan and a preparation method for the plywood. The preparation method comprises the following steps of: preparing materials, wherein thickness difference between a eucalyptus core veneer and a eucalyptus long-center veneer is not more than 0.3mm; assembling; hot-pressing, namely performing hot-pressing on a three-layer blank veneer subjected to cold repair; hot stacking for 24 to 72 hours to cure glue water and eliminate stress; cutting an edge, supplying putty, sanding and veneering; hot-pressing the veneered 5-layer veneer; cooling, and hot staking for 2 to 3 days; cutting an edge; performing humidifying and formaldehyde pollution resistant posttreatment; eliminating secondary stress; and performing surface treatment and wood grain filling to obtain the veneer special for the wood blade of the classical ceiling fan. The veneer special for the wood blade of the classical ceiling fan has the advantages of small deformation, high integral strength, flat and smooth surface and no torn grains.

Description

technical field [0001] The invention relates to a special plywood for classical ceiling fan leaves and a preparation method thereof. Background technique [0002] At present, there are two common methods of plywood for classical ceiling fan leaves on the market: [0003] 1. Imported 2.7mm whole meranti boards are used to compound into 5.4mm boards. The overall structure is 6-layer boards, and the middle layer is in the same direction. This production method is the mainstream method, but it has the following disadvantages: long order cycle, secondary processing is required, high cost, rough surface texture, difficult to control formaldehyde emission, generally only reach E1 level) [0004] 2. According to the general practice of secondary molding of plywood for indoor use. This method has the following disadvantages: the degree of deformation of the board cannot be controlled, the holes of the board cannot be controlled, there is no standard for the static bending strength ...
