Embodiment 1
[0064] As a preferred embodiment of the present invention, when the thickness T of the pine laminated lumber 2 of the core material 3 is usually 20mm, the laminated veneer lumber 1 usually has 7 layers, and the thickness specification of a single layer of the laminated veneer lumber 1 is 1.7mm.
[0065] As described in this example and combined with Figure 5 It can be seen that the process for making novel woody core material comprises the following steps,
[0066] S1, making prefabricated laminated veneer lumber;
[0067] (1). Rotary cutting board: cutting the log into a veneer with a thickness of 1.7 mm;
[0068] (2).Steaming and drying: The 1.7 mm veneer cut by rotary cutting is dried in the air, and then dried by a dryer at 100-120 ℃, and the moisture content of the veneer is controlled at 8%;
[0069] (4). Glue coating: The veneer with a thickness of 1.7 mm is dried by steaming and drying, and is glued by a glue coating machine. The glue is phenolic glue, and the forma...

Abstract
The invention discloses a novel wooden core material. The material is mainly characterized in that at least three layers of laminated veneer lumber are arranged, the laminated veneer lumber is separately connected to the upper end surface and the lower end surface of pine laminated wood to form the core material in a cube or cuboid shape, a thickness value of the pine laminated wood is T, and theminimum length of the core material is L. The wood core material has the beneficial effects that the defect of distortion of an existing wooden core material is overcome, the core material is high inoverall density, small in glue content, high in core hardness, high in strength and good in toughness of the upper side and the lower side, the core material can be recycled and reused and can be madeinto a blocky core material or secondarily processed to be used as wooden particles, shaving board materials and the like, and the core material is low in manufacturing cost and more environmentallyfriendly.
Description
technical field [0001] The invention relates to a core material, in particular to a novel wood core material. Background technique [0002] In the field of furniture or wooden doors, the wooden core material is an indispensable production material in this field. Among the existing traditional wooden core materials, the core material made of wood particle board or particle board material and the laminated veneer lumber itself are mainly used. The finished wood core material is most common. In addition, there are fewer and fewer woody core materials made solely of woody raw materials. Procurement channels are limited and the production cycle is delayed. [0003] The disadvantage of the core material made of wood particle board or particle board material is that the density of the core material is low, which is far less than that of the wood core material made of wood raw materials, and a large amount of chemical bonding is used in the production process. agent, not environm...
