Abstract

The invention discloses a composite slab with a symmetric structure and a manufacturing method thereof. The composite slab with the symmetric structure comprises two surface layers and core layers inside the two surface layers, wherein the core layers are formed by overlapping a plurality of layers of saw cutting plates, and each layer of saw cutting plates is adhered with each other by using an adhesive. The core layers are formed by overlapping the saw cutting plates with the thickness of 5 to 1.5 mm; a middle layer is arranged between each surface layer and each core layer and is a single plate with the thickness of 1.5-2.5 mm; the surfaces of the saw cutting plates are provided with a plurality of dot-line shaped crackles along a direction of wood grain; and the average length of the cracks is between 2.5 mm and 4.8 mm, the width is between 0.5 mm and 2.5 mm, the depth is 40 to 60 percent of the thickness of the saw cutting plates of the core layers, and the distance between the crackles is between 1 cm and 4.8 cm. The invention has the advantages of simple structure, firmness, durability, concise procedures of the manufacturing method, wide application range and easy popularization, can be used as raw materials of any panel-type furniture, and is suitable for processing and manufacturing various kinds of fast-growing tree timber composite plates.

Description

technical field [0001] The invention relates to a composite board for wooden furniture, more specifically a composite board with a symmetrical structure and a manufacturing method thereof. Background technique [0002] With the continuous maturity of the panel furniture market, more and more large-scale furniture manufacturers and even forest and wood research institutes have begun to focus on the research and innovation of composite panels, but the innovation is ultimately the use of high-quality wood raw materials and the half-layer structure of composite panels. Combined with excellent processing technology for production. At present, it is very convenient to import wood from abroad, and there are many channels, but it is mainly concentrated in the original growth of Nanyang wood, West African wood, Russian wood and other broad-leaved wood species, and the unit price is more than several thousand yuan, and the cost is relatively high. At the same time, many countries and...
