Problems solved by technology

However, this method of carbonizing bamboo has the following disadvantages: (1) It takes a long time to carbonize bamboo with hot air for more than 20 hours to complete deep carbonization; (2) uneven carbonization, because it is difficult for hot air to quickly enter the interior of bamboo, resulting in uneven internal and external carbonization ; (3) Color difference, due to the difference in the surface temperature of bamboo in different positions, the degree of carbonization is different, and the difference in color on the surface of bamboo affects its aesthetics; Substances such as cellulose in bamboo play the role of adhesive cellulose and can enhance the strength of bamboo. The hot air carbonization method will completely degrade such substances, which seriously damages the compression resistance of bamboo and makes it brittle and brittle.

Embodiment 1

[0029] 1. Cold pressing of bamboo

[0030] (1) Lay the soaked and dried bamboo shreds or slices into a press and cold-press them into squares.

[0031] (2) Send the above-mentioned square materials into the tunnel for thermal curing;

[0032] (3) Take out the heat-cured square material from the mold.

[0033](4) Process the square material taken out of the mold into a slab.

[0034] 2. Oil heat treatment

[0035] Slowly put the slab into a 100°C alkylbenzene-type heat-conducting oil bath for 1 hour, and when placed, the direction of the vascular bundles of the bamboo is perpendicular to the surface of the hydrophobic medium. When the temperature of the heat transfer oil is 50°C, take out the heavy bamboo flooring and let it cool down to room temperature naturally.

[0036] 3. Surface treatment

[0037] Coat a layer of vegetable oil on the outer surface of heavy bamboo floor after oil heat treatment.

Embodiment 2

[0039] 1. Cold pressing of bamboo

[0040] (1) Lay the soaked and dried bamboo shreds or slices into a press and cold-press them into squares.

[0041] (2) Send the above-mentioned square materials into the tunnel for thermal curing;

[0042] (3) Take out the heat-cured square material from the mold.

[0043] (4) Process the square material taken out of the mold into a slab.

[0044] 2. Oil heat treatment

[0045] Slowly put the slab into the alkylbenzene type heat transfer oil at 200°C for 2 hours, and the direction of the bamboo vascular bundles is perpendicular to the surface of the hydrophobic medium. When the temperature of the heat transfer oil is 200°C, take out the heavy bamboo flooring and let it cool down to room temperature naturally.

[0046] 3. Surface treatment

[0047] Coat a layer of vegetable oil on the outer surface of heavy bamboo floor after oil heat treatment.

Embodiment 3

[0049] 1. Cold pressing of bamboo

[0050] (1) Lay the soaked and dried bamboo shreds or slices into a press and cold-press them into squares.

[0051] (2) Send the above-mentioned square materials into the tunnel for thermal curing;

[0052] (3) Take out the heat-cured square material from the mold.

[0053] (4) Process the square material taken out of the mold into a slab.

[0054] 2. Oil heat treatment

[0055] Slowly put the slab into the 300°C alkylbenzene heat transfer oil and soak it for 10 hours. When putting it in, the direction of the bamboo vascular bundle is perpendicular to the surface of the hydrophobic medium. When the temperature of the heat transfer oil is 170°C, take out the heavy bamboo flooring and let it cool down to room temperature naturally.

[0056] 3. Surface treatment

[0057] Coat a layer of vegetable oil on the outer surface of heavy bamboo floor after oil heat treatment.

Abstract

The invention provides a manufacturing process of outdoor strand woven bamboo floors. The process comprises two main stages, namly cold pressing and manufacturing plates, and carrying out oil heat treatment, and comprises the following steps: putting processed and manufactured plate blanks into a hydrophobic organic medium of 100-300 DEG C after the stage of cold pressing and manufacturing bamboo filaments or bamboo sheets into plates, then dipping the plate blanks for 1-10 hours, taking the plate blanks out, standing and cooling to the room temperature, and coating the surfaces of the plate blanks with a layer of plant oil. Compared with a manufacturing process of strand woven bamboo floors in the prior art, the outdoor strand woven bamboo floors manufactured by the process have the advantages of mold resistance, insect damage resistance, deformation resistance and cracking resistance; the process is high in efficiency, low in cost, high in compressive property and free of surface color difference.

Description

technical field [0001] The invention belongs to the field of floor manufacturing, and in particular relates to a manufacturing process of an outdoor heavy bamboo floor that is mildew-proof, moth-proof, non-deformable and non-cracking. Background technique [0002] Outdoor floors can be seen everywhere in parks and communities, and these floors play a good decorative role. Many of the existing outdoor floors are bamboo products, which are prone to problems such as swelling deformation, cracking, mildew, and insects after being exposed to rain, wind, severe cold and heat, which seriously affects its appearance. The root cause of these problems is the characteristics of bamboo. Bamboo is mainly composed of cellulose, hemicellulose, lignin and extract, among which cellulose, lignin and hemicellulose are the main body, and cellulose and hemicellulose contain a large number of hydrophilic groups - hydroxyl groups, so When exposed to water, bamboo will absorb a large amount of wa...
