Embodiment 1

[0025] Example one: such as figure 1 The structure diagram of the composite board of the present invention shown is a 0.6mm thick oak tempered wood. The first layer: 0.45mm thick oak panel, the back is glued with non-woven fabric; the second layer: 0.05m thick high molecular weight glue dipping paper; the third layer: 0.2mm thick kraft paper; the fourth layer: 0.1mm thick small molecular weight glue dipping Glue paper, 5th layer, 0.5mm thick poplar veneer, 6th layer: 0.1mm thick small molecular weight glue dipped paper.

[0026] Large molecular weight glue components include melamine 50%-55%, plasticizer 35%-40%, formaldehyde 3%-5%; small molecular weight glue components include melamine 70%-82%, plasticizer 5%- 12%, formaldehyde 3%-6%; the non-woven fabric or glass fiber net bonded on the back of the surface layer can prevent the surface layer from cracking. The number of non-woven fabric or glass fiber network depends on the material type, and the thickness is 0.45mm oak panel ...

Embodiment 2

[0034] Embodiment two: such as figure 2 The structure diagram of the composite board of the present invention shown is a black walnut tempered wood with a thickness of 1.1 mm. The first layer: 0.5mm thick black walnut panel, the back is bonded with non-woven fabric; the second layer: 0.05m thick high molecular weight glue dipped paper; the third layer: 0.2mm thick kraft paper; the fourth layer: 0.1mm thick small molecular weight glue Impregnated paper, 5th layer: 0.8mm thick poplar veneer, 6th layer: 0.1mm thick small molecular weight glue dipping paper, 7th layer: 0.8mm thick poplar veneer, 8th layer: 0.1mm thick small molecular weight glue dipping paper.

[0035] Large molecular weight glue components include melamine 50%-55%, plasticizer 35%-40%, formaldehyde 3%-5%; small molecular weight glue components include melamine 70%-82%, plasticizer 5%- 12%, formaldehyde 3%-6%; 0.5mm black walnut panel is pasted with 20 mesh non-woven fabric on the back to prevent surface cracking. ...

Embodiment 3

[0043] Example three: such as image 3 The structure diagram of the composite board of the present invention shown is a black walnut tempered wood with a thickness of 2.1 mm. The first layer: 0.5mm thick black walnut panel, the back is bonded with non-woven fabric; the second layer: 0.05m thick high molecular weight glue dipped paper; the third layer: 0.2mm thick kraft paper; the fourth layer: 0.1mm thick small molecular weight glue Impregnated paper, 5th layer: 0.8mm thick poplar veneer, 6th layer: 0.1mm thick small molecular weight glue dipping paper, 7th layer: 0.8mm thick poplar veneer, 8th layer: 0.1mm thick small molecular weight glue dipping Paper, the 9th layer: 0.8mm thick poplar veneer, the 10th layer: 0.1mm thick small molecular weight glue dipped paper, the 11th layer: 0.8mm thick poplar veneer, the 12th layer: 0.1mm thick small molecular weight glue dipped paper.

Abstract

The invention discloses a composite board and a production method thereof, and relates to the field of building materials. The composite board comprises a bamboo veneer surface layer, and glue-dipped paper layers and kraft paper which are sequentially and repeatedly arranged, or glass fiber net layers, glue-dipped paper layers and bamboo veneer layers which are sequentially and repeatedly arranged, wherein all the layers are pressed and connected together through high temperature and high pressure, large-molecular-weight glue is adopted for the first glue-dipped paper layer under the bamboo veneer surface layer, and small-molecular-weight glue is adopted for the rest of the glue-dipped paper layers. The production method of the composite board includes the following steps of firstly, conducting high-temperature desugaring and degreasing on the bamboo veneer layers except the bamboo veneer surface layer; secondly, attaching non-woven fabric or a glass fiber net to the back face of the bamboo veneer surface layer; thirdly, drying and balancing all the bamboo veneer layers processed in the first step and the second step; fourthly, absorbing fire retardant from the dried and balanced bamboo veneer layers through the negative pressure mode; fifthly, sequentially, repeatedly and flat laying the bamboo veneer surface layer, the glue-dipped paper layers and the kraft paper or laying the glass fiber net layers, the glue-dipped paper layers and the bamboo veneer layers on a pressing machine layer by layer, and closely pressing all the bamboo veneer layers and the kraft layers or pressing the glass fiber net layers and the glue-dipped paper together through pressure of the pressing machine. By means of the technical scheme, the composite board has effects of water prevention, fire retardance and high strength.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a composite board and a production method thereof. technical background [0002] The existing composite board, such as fireproof board, is made of base paper (titanium powder paper, kraft paper) through melamine and phenolic resin impregnation process at high temperature and high pressure. It is not a real bamboo and wood material, and has the disadvantages of non-waterproof and poor impact resistance; Bamboo and wood materials, laminate flooring materials, etc., in terms of their materials, have the disadvantages of being non-waterproof, non-flammable, and poor in impact resistance. They will swell and deform and twist when exposed to water until they are damaged. They will easily absorb stains after absorbing water. Produce mold, mites, etc., which is not conducive to human health; Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the purpose...
