Problems solved by technology

However, the growth of hardwood trees is slow and hardwood trees are difficult to produce for many years. Due to forest protection, logging is banned in various countries, and the raw materials are exhausted. It is difficult for hardwood furniture factories and hardwood floor factories to cook without rice, and consumers are looking forward to it.
[0003] CN1282654A discloses Mr. Yang Zhiliang's patented technology of "reinforced solid wood composite tongue and groove floor board production method". The core board is made of pine wood or fast-growing forest material, and the surface layer of the core board is pasted with wood grain decorative layer, aluminum oxide wear-resistant layer, melamine Flame-retardant layer, grooved around to form a floor, this technology produces a multi-layer composite floor, without applying strong pressure and a large amount of glue, the degree of reinforcement is average
[0005] Both of the above two patents have a low level of strengthening, and the products do not quite conform to the psychology of Xishimu popular among consumers today.

Embodiment 1

[0019] Embodiment 1: Thinning fir with diameter at breast height of 20cm is roughly made into wide 150mm, thick 19mm, long 1500mm thick plate, stacks and dries in drying kiln, has according to existing drying standard, is dried to moisture content 6%, after cooling Carry out rough planing, then heat to 135°C for about 15 minutes, put it out of the kiln while it is hot, and put it into a phenolic resin pool at room temperature for about 8 minutes, so that the absolute dry solid content of the resin is 5%, and then send it to an ordinary multi-layer hot press machine for heating. Press for 450 seconds, temperature control 150°C, compression ratio 10%, take it out and put it aside for 24 hours, use a planer on both sides to plan the side grooves, sand the upper and lower sides, mill the grooves at both ends, and then paint to make a grooved floor with a density of 480kg / m 3 , the surface hardness reaches 35Mpa, the longitudinal static bending strength is 52Mpa, and the longitudi...

Embodiment 2

[0020] Embodiment 2: Select poplar wood, the water content after drying is 8%, impregnate with urea-formaldehyde resin, hot and cold method, the absolute dry solid content of resin reaches 7%, hot pressing temperature 120 ℃, time 1000 seconds, compression ratio 12%, Aged for 15 hours, planed both sides with a double-sided planer, sanded the upper and lower sides, and made a non-grooved painted floor with a density of 500kg / m 3 , the surface hardness reaches 45Mpa, the longitudinal static bending strength is 60Mpa, and the longitudinal elastic modulus is 3.5Gpa. All the other are with embodiment 1.

Embodiment 3

[0021] Example 3: Choose pine wood, dry and degrease, with a moisture content of 7%, impregnate with phenolic resin by cold and hot method, the absolute dry solid content of the resin reaches 4.5%, hot pressing temperature 170 ° C, time 600 seconds, compression ratio 6%, and put it aside After 30 hours, it is made into a furniture raw material board, which is planed and painted together when the furniture is to be made. Density 680kg / m 3 , the surface hardness reaches 60Mpa, the longitudinal static bending strength is 80Mpa, and the longitudinal elastic modulus is 6.2Gpa. All the other are with embodiment 1.

Abstract

A soft material quality wood material strengthening board is flat plate. It is characterized by: it has natural grains of raw wood, its color is the mixture color of raw wood self color, charring color and resin color, the density is 450-720kg / m<3>, surface hardness is 25-65MPa, vertical MOR is 35 - 90MPa, vertical elastic modulus is 1~10GPa, resin content (solid content) is 3% - 10%. The strengthening board can be produced floors or furniture raw materials after preliminary working, drying, rough planing, heating, resin soaking, hot pressing, placing in normal condition and fine finishing. The invention produces the strengthening board using soft material as raw material, covers the shortage of hardwood product raw materials, it increases the use-value of soft material, while meets the popular consumer demand of liking wood, and provides new materials for hardwood furniture and flooring manufacturing industry.

Description

technical field [0001] The invention relates to a method and a product for producing a solid wood reinforced board by using soft wood as a raw material. Background technique [0002] Hardwood products are favored by many consumers, especially hardwood furniture and hardwood floors. However, hardwood trees grow slowly and have been difficult to produce for many years. In addition to forest protection, logging is banned in various countries, and raw materials are exhausted. It is difficult for hardwood furniture factories and hardwood floor factories to cook without rice, and consumers are looking forward to it. [0003] CN1282654A discloses Mr. Yang Zhiliang's patented technology of "reinforced solid wood composite tongue and groove floor board production method". The core board is made of pine wood or fast-growing forest material, and the surface layer of the core board is pasted with wood grain decorative layer, aluminum oxide wear-resistant layer, melamine The flame-retar...
