Description

Pine poplar composite plywood

Technical field

The utility model relates to composite board technical fields, specifically pine poplar composite plywood.

Background technique

Currently, the composite board to be circulated in the market is typically all to cause in such a way that veneer is compound come what is made again The whole fastness of plywood material is inadequate, causes composite board to be integrally easy degumming and warp, therefore at this stage it is desirable that one Stronger composite board can be adhesively fixed in kind.

Summary of the invention

The utility model, which provides, a kind of is adhesively fixed pine poplar composite plywood that is stronger, being not easy to warp.

The utility model is achieved through the following technical solutions:

A kind of pine poplar composite plywood, including three layers of deal board and two layers of poplar plate, three layers of deal board difference For the first deal board, the second deal board and third deal board, the poplar plate is respectively the first poplar plate and the second poplar plate, institute It states the first poplar plate to be set between first deal board and the second deal board, the second poplar plate is set to second pine Between plate and third deal board, on the lower surface of first deal board, on the upper surface of the third deal board and described Several square grooves, the upper and lower surface of the first poplar plate and the second poplar plate are equipped in the upper and lower surface of two deal boards On be equipped with several square protrudings, the square groove is corresponded to each other with the position of the square protruding, the square protruding It is embedded in inside the square groove.

Between first deal board and the first poplar plate, the first poplar plate and second deal board it Between, between second deal board and the second poplar plate, it is logical between the second poplar plate and the third deal board Cross compound adhesive bonding.

First deal board, the second deal board and third deal board with a thickness of 1.8 millimeters, the first poplar plate and Second poplar plate with a thickness of 1.3 millimeters, the depth of the square groove is 0.3 millimeter, and the height of the square protruding is 0.3 Millimeter.

The length of the pine poplar composite plywood is 240 centimetres, and width is that 120 cm thicks are 0.8 centimetre.

Beneficial effect brought by the utility model is:

The most main in the utility model is exactly that square groove and square protruding are equipped between each laminate, passes through this The connection of kind mode and the bonding for adding compound adhesive, play and stronger mesh are adhesively fixed between each laminate material , so that the integral firmness of such pine poplar composite plywood is higher.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and embodiments:

As the embodiment of pine poplar composite plywood described in the utility model, as shown in Figure 1, Figure 2 and Figure 3, including Three layers of deal board 1 and two layers of poplar plate 2, three layers of deal board 1 are respectively the first deal board 3, the second deal board 4 and third pine Plank 5, the poplar plate 2 are respectively the first poplar plate 6 and the second poplar plate 7, and the first poplar plate 6 is set to first pine Between plank 3 and the second deal board 4, the second poplar plate 7 is set between second deal board 4 and third deal board 5, institute It states on the lower surface of the first deal board 3, on the upper surface of the third deal board 5 and the upper and lower surface of second deal board 4 On be equipped with several square grooves 8, be equipped in the upper and lower surface of the first poplar plate 6 and the second poplar plate 7 several Square protruding 9, the square groove 8 are corresponded to each other with the position of the square protruding 9, and the square protruding 9 is embedded in the side Inside connected in star 8.

In the present embodiment, between first deal board 3 and the first poplar plate 6, the first poplar plate 6 with it is described Between second deal board 4, between second deal board 4 and the second poplar plate 7, the second poplar plate 7 and described the It is bonded by compound adhesive between three deal boards 5.

In the present embodiment, first deal board 3, the second deal board 4 and third deal board 5 with a thickness of 1.8 millimeters, institute State the first poplar plate 6 and the second poplar plate 7 with a thickness of 1.3 millimeters, the depth of the square groove 8 is 0.3 millimeter, the side The height of shape protrusion 9 is 0.3 millimeter.

In the present embodiment, the length of the pine poplar composite plywood is 240 centimetres, and width is that 120 cm thicks are 0.8 centimetre.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
