Embodiment 1

[0023] A cedar three-layer solid wood composite floor, which is composed of a wear-resistant primer layer 1, a surface board 2, a core board 3 and a bottom board 4 from top to bottom,

[0024] The wear-resistant primer layer 1 has a thickness of 5-200 μm;

[0025] The said surface plate 2 is sawed cedar into a thin plate with a thickness of 3.2-4mm;

[0026] The core board 3 is sawing the cedar into boards, planing and sawing to cut into cedar slats with a width of 25-50 mm and a thickness of 8-9 mm, and side-assembling the cedar slats as the core board;

[0027] Described base plate 4 is that poplar wood is rotary-cut veneer, and its thickness is 2mm.

Embodiment 2

[0029] 1. Raw material preparation: the surface board is made of sawn cedar thin board with a moisture content of 10-12%, and the thickness is 3.2-4mm. The core board is made of cedar lath, with a thickness of 8-9mm and a width of 25-50mm. At about 10-12%, the base plate is made of poplar veneer with a thickness of 2mm and a moisture content of 8-10%;

[0030] 2. Glue application: use urea-formaldehyde resin adhesive to apply glue to the surface plate and bottom plate, and the amount of glue applied is 180-220g / m 2 ;

[0031] 3. Blank assembly: assemble the surface plate, core plate and bottom plate after gluing, the gap between the cedar slats of the core plate is not more than 0.5mm, and the aging time after assembly is 0.5-1h;

[0032] 4. Hot pressing: Hot pressing process is adopted, the hot pressing pressure is 0.85-1.0MPa, the hot-pressing temperature is 95-100°C, and the hot-pressing time is 6-12 minutes;

[0033] 5. Chen Fang: Chen Fang health preservation time is 3 ...

Abstract

The invention belongs to the technical field of wooden floor production and relates to a cryptomeria fortunei three-layer solid wood composite floor and a preparation method thereof. The cryptomeria fortunei three-layer solid wood composite floor is composed of a wear-resisting primer layer, a surface board, a core board and a bottom board orderly from top to bottom. The preparation method of the cryptomeria fortunei three-layer solid wood composite floor comprises manufacturing a rough product by use of a cryptomeria fortunei sheet as the surface board, a common cryptomeria fortunei batten as the core board and a poplar veneer as the bottom board and by virtue of the steps of gumming, assembling, hot-press gluing, cooling, sanding and the like, applying a wear-resisting paint on the surface of the rough product in a roller coating manner to form the wear-resisting primer layer, and finally obtaining the cryptomeria fortunei three-layer solid wood composite floor. According to the cryptomeria fortunei three-layer solid wood composite floor, the elasticity of the floor can be improved, the surface wear resistance of the floor can be improved and the durability of the floor can be improved; as the cryptomeria fortunei is short in growth cycle, and low in raw material price, and the preparation method is simple and the preparation cost is low, the prepared cryptomeria fortunei three-layer solid wood composite floor is capable of greatly increasing the economic benefit and the social benefit of an enterprise.

Description

Technical field [0001] The present invention belongs to the field of wooden floor production technology, involving solid wood composite floors, and especially involves a three -layer solid wood composite floor and its preparation methods. Background technique [0002] As the global natural forest resources have decreased sharply, the wood processing industry has become increasingly short of raw materials.As an important decorative material for indoor decoration, wooden floors are getting larger and larger.In order to solve the contradiction between the supply and demand of wood, my country has vigorously cultivated the rapid artificial forests mainly from poplars and cedar, filling the vacancy of wood resources. [0003] In the domestic market, solid wood composite flooring is the fastest -growing product in the floor industry. The solid wood composite floor has three layers of solid wood composite floor and multi -layer solid wood composite floor.At present, the three -layer sol...
