Problems solved by technology

However, compared with hard broad-leaved wood, Chinese fir is poor in material, loose in structure, low in strength and hardness, not wear-resistant, easy to absorb moisture, unstable in size, and has few practical applications, accounting for 20% to 25% of China's commercial wood. Chinese fir has not been rationally and effectively utilized so far

Embodiment 1

[0017] A kind of preparation method of Chinese fir floor, comprises the steps:

[0018] (1) Choose fir panels with a moisture content of 8%-10% (high moisture content is easy to degumming and cracking, if the moisture content is too low, it will absorb too much glue, and it is easy to lack glue, thereby reducing the bonding strength); the core board is made of good gluing performance Sliced ​​oak veneer, sliced ​​the log, dried the veneer, and sanded it to a thickness of 1.5mm, arranged the annual ring texture of two adjacent veneers in a symmetrical shape, so as to avoid warping out of shape.

[0019] (2) The bottom board is spliced ​​with Chinese fir, which is dried with superheated steam under normal pressure (so that the board can be prevented from being deformed in the future), and then spliced ​​into boards, planed on both sides, and sanded on the glued surface, and finally a fir with a thickness of 17-19mm is obtained Floor; in this way, it can effectively prevent the ...

Abstract

An embodiment of the invention discloses a preparation method of a fir floor. The method comprises the steps as follows: (1) a fir panel with the moisture content ranging from 8% to 10% is selected; acore plate adopts oak type sliced veneers having the good gluing performance, logs are sliced, veneer drying is performed, then the veneers are subjected to fixed-thickness sanding to be 1.5 mm, andgrowth ring textures of the two adjacent veneers are symmetrically arranged and joined; (2) a bottom plate is formed through joining of fir, the fir is subjected to normal-pressure superheated steam drying treatment and then is joined into the plate, double sides are dressed, the gluing surface is sanded, and the fir floor being 17-19 mm thick is obtained finally; (3) modified polyvinyl acetate copolymer emulsion glue is adopted, and the gluing quantity is ensured to range from 110 g / m<2> to 115 g / m<2>; (4) assembling is performed in a texture crossing manner; (5) a slab is subjected to molding machining.

Description

technical field [0001] The invention relates to the field of interior decoration materials, in particular to a preparation method of fir flooring. Background technique [0002] Chinese fir is a unique tree species in China. It is an important fast-growing ecologically safe public welfare forest species that is compatible with the environment of Hunan Province. Yunnan and other provinces are distributed. Chinese fir is the most important commercial material in southern China, and can be widely used in construction, bridges, poles, doors and windows, furniture, panels, and wooden utensils. However, new building materials such as metal and plastic have gradually replaced the application fields of wood in a relatively short period of time, resulting in a sharp decline in the use of fir wood, and a sharp drop in demand. The phenomenon. For a long time, insufficient work has been done to develop fir industrialized panel products, which has become a national problem. Wood extra...
