Problems solved by technology

[0004] At present, most of the surface layer of large shaving OSB boards on the market are criss-crossed, and cannot be pressed and pasted with melamine impregnated paper normally, and there are shaving indentations and cavities on the surface of the decorative paper, which seriously limits the scope of application of OSB boards in the field of decoration.

preparation example Construction

[0027] In addition, an embodiment of the present invention also provides a method for preparing the double-faced oriented strand board described in any of the above embodiments, the preparation method includes: pressing and pasting melamine continuous lamination paper on the upper surface and the lower surface of the substrate respectively surface to form the first layer and the second layer on the upper and lower surfaces of the substrate layer.

[0028] Preferably, the pressing is cold pressing;

[0029] Preferably, the cold pressing conditions are as follows: the pressure is 12-15 MPa, the temperature is 5-25° C., and the cold pressing time is 24-48 hours. The cold pressing time varies adaptively with the temperature, the lower the temperature, the longer the cold pressing time, and the higher the temperature, the shorter the cold pressing time adaptively. For example, when the temperature is 16-25°C, the duration of cold pressing is about 24 hours; when the temperature is...

Embodiment 1

[0040] A preparation method of double facing oriented strand board, which comprises the following steps:

[0041] (1) Preparation of melamine continuous laminated paper.

[0042] After the melamine printing paper is soaked in glue, it is pressed by a press. After the pressing is completed, it is taken out and placed flat on a flat platform for stacking. Melamine continuous laminated paper with a weight of 190g / m 2 , the thickness is 0.3 ~ 1.2mm.

[0043] (2) Substrate processing.

[0044] Obtain oriented strand board as the substrate, the density of the substrate is ≥650g / cm 3 , the thickness is 20mm.

[0045] Use a sander to sand the surface of the substrate, adjust the height of the gasket, set the sanding thickness to 2mm, and control the position of the abrasive belt to sand the entire board evenly.

[0046] (3) Apply glue and check the equipment status of the roller coating machine.

[0047] According to the thickness of the OSB substrate, carry out the lifting adju...

Embodiment 2

[0056] A preparation method for double-faced oriented strand board is roughly the same as the preparation method step provided in Example 1, the difference is that some parameters are different, and the difference is as follows: the weight of the melamine continuous laminated paper is 220g / m 2 .

Abstract

The invention discloses a double-veneer oriented strand board and a preparation method thereof. The double-veneer oriented strand board comprises a first layer, a base board layer and a second layer from top to bottom, wherein the first layer and the second layer are both made of melamine continuous laminated paper. The melamine continuous laminated paper is pressed and attached to the surface of a base plate, the surface of the prepared double-veneer oriented strand board is smoother and more attractive, the prepared double-veneer oriented strand board has very high physical and mechanical properties, meanwhile, the double-veneer oriented strand board is capable of effectively isolating strong permeation of water vapor, avoiding or reducing the release of formaldehyde of the board, and improving the household air quality, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of OSB decorative boards, in particular to a double-faced oriented strand board and a preparation method thereof. Background technique [0002] In the field of home decoration materials, melamine-impregnated paper is widely used in furniture production, wall panels, floor and ceiling accessories due to its rich and varied patterns, excellent stain resistance, abrasion resistance and water vapor resistance, and is favored by consumers. However, the release of formaldehyde from melamine-impregnated paper has attracted the attention of consumers. [0003] The scientific name of OSB board is oriented strand board, which is made of small-diameter wood, thinning wood and wood core as raw materials, and processed into long shavings (generally 40-100mm long, 5-20mm wide, 0.3-0.7mm thick) through special equipment. , a directional structural board made by deoiling, drying, sizing, directional paving and hot pressing...
