Manufacturing process of outdoor strand woven bamboo floors

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...

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.

[0003] CN103802185A discloses a high-temperature physical carbonization method and its carbonization furnace equipment. The wood carbonized by this method has a good anti-corrosion and anti-mildew effect, but the carbonization time is long, the cost is high, the carbonization is uneven, the compression resistance is poor, and the surface has color difference

However, this technology needs to heat up slowly in stages. When cooling, it needs to be cooled to a certain temperature in the treatment tank before it can be taken out, so as to ensure that the material will not crack or deform during the oil bath process. The processing time is longer, so the production efficiency is low.

At the same time, this technology only stays at heat treatment for wood modification treatment, and the duct structure of bamboo is more developed. When it is directly applied to bamboo, the treated bamboo will exchange with external moisture, and the size of the product will be changed during use. Normal use
