Embodiment 1

[0015] This embodiment discloses a novel Chinese fir board, comprising the following components by weight ratio:

[0016]

[0017] The moisture content of described Chinese fir is 10%. The adhesive is urea-formaldehyde resin with a viscosity of 0.12 Pa.s (20° C.). The curing agent is NH 4 Cl. The waterproofing agent is molten paraffin. The novel Chinese fir board of the present invention also includes putty, usually shellac putty. The filler is industrial flour.

Embodiment 2

[0019] This embodiment discloses a novel Chinese fir board, comprising the following components by weight ratio:

[0020]

[0021]

[0022] The moisture content of the Chinese fir is 8-10%. The adhesive is urea-formaldehyde resin with a viscosity of 0.12 Pa.s (20° C.). The curing agent is NH 4 Cl. The waterproofing agent is molten paraffin.

[0023] The novel Chinese fir board of the present invention also includes putty, usually shellac putty. The filler is industrial flour.

Abstract

The invention provides a novel fir board. The novel fir board is prepared from the following constituents in parts by weight: 60-80 parts of fir, 10-20 parts of an adhesive, 5-10 parts of a waterproof agent, 2-10 parts of a filler, and 2-5 parts of a curing agent. The novel fir board disclosed by the invention is simple and accessible in formula; compared with the prior art, the novel fir board has the following advantages: the moisture content, the surface bonding strength and the dipping and stripping length index of the fir board meet the requirements in international GB / T15104-94; in addition, the surface after veneering of the base material is free of crack and glue penetration; the physical and mechanical properties can be improved; the range of application can be expanded; the board can be used for common furniture and indoor decoration.

Description

technical field [0001] The invention relates to board technology, in particular to a novel fir board. Background technique [0002] Glulam is one of the types of wood-based panels that can make full use of small-diameter timber to produce high-grade materials. Through a series of processes such as machining and gluing, it reassembles small strips of small materials into large-scale panels, wooden squares, and wooden beams. High value-added construction and decoration materials have been extensively researched, produced and applied at home and abroad. The domestic production of glulam has initially formed an industry, but the scale of the manufacturers is generally small, the output is low, and the technology is not good. There are some problems. There are few tree species used. In terms of industrial fast-growing timber, paulownia is used more, but the utilization of fir, poplar, eucalyptus, etc. is less, especially the southern fast-growing fir. There are many, and the mat...
