Problems solved by technology

However, fast-growing and high-yield wood such as tung tree has the disadvantage of soft material due to the short growth period and the physical characteristics of the tree species, so its use is limited to a certain extent.

example 1

[0014] Example 1. The artificial fast-growing tung tree log is sawed into 1000 * 150 * 28 (mm) slab blanks, and then soaked in a clear water pool until the water content reaches 100%.

[0015] Finally, put the slab blank into an airtight container for high-temperature cooking, degrease and soften, and then pre-dry until the water content is below 20%.

[0016] Then put the pre-dried slab into the hot press for heating and compression, so that the slab is gradually dried and densified. According to the technical requirements of the material, the slab is dried to a moisture content of 12% and densified to a compression rate of 30%. , and then turn off the hot steam, inject cooling water into the hot press plate, so that the plate blank is cooled and shaped.

[0017] Finally, unload the shaped slabs from the hot press, apply waterproofing agent around the sides and both sides of the slabs, stack them neatly, and regain moisture for ten days. After the internal stress of the slabs...

example 2

[0018] Example two. The artificial fast-growing tung tree log is sawed into a slab stock of 1000 * 120 * 32 (mm), and then soaked in a clear water pool until the water content reaches 90%.

[0019] Finally, put the plank blank into an airtight container for high-temperature cooking, and after degreasing and softening, perform pre-drying treatment until the moisture content is below 20%.

[0020] Then put the pre-dried slab into the hot press for heating and compression, so that the slab is gradually dried and densified. According to the technical requirements of the material, the slab is dried to a moisture content of 10% and densified to a compression rate of 40%. , and then turn off the hot steam, inject cooling water into the hot press plate, so that the plate blank is cooled and shaped.

[0021] Finally, unload the shaped slab blank from the hot press, apply waterproofing agent on the surrounding and both sides of the slab blank, stack it neatly, and regain moisture for 12...

example 3

[0022] Example three. The artificial fast-growing tung tree log is sawed into 1000 * 100 * 36 (mm) slab blanks, and then soaked in a clear water pool until the water content reaches 80%.

[0023] Finally, put the slab blank into an airtight container for high-temperature cooking, degrease and soften, and then pre-dry until the water content is below 20%.

[0024] Then put the pre-dried slab into the hot press for heating and compression, so that the slab is gradually dried and densified. According to the technical requirements of the material, the slab is dried to a moisture content of 8% and densified to a compression rate of 50%. ,. Then turn off the hot steam, and inject cooling water into the hot pressing plate to cool and shape the blank.

[0025] Finally, unload the shaped slabs from the hot press, apply waterproofing agent on the surrounding and both sides of the slabs, stack them neatly, and regain moisture for 15 days. After the internal stress of the slabs is determi...

Abstract

The invention discloses a manufacturing method of tong-oil tree modified floor, which belongs to the technical field of artificial floor product manufacturing, and is characterized in that tong-oil trees of artificial quick growth economic forest serve as the raw material; and first the tong-oil trees are sawed into floor ingots with required specification, and the tong-oil tree modified floor iscompleted through soaking, cooking, pre-drying, hot pressing, cooling, shaping, resurgence and other processes. The tong-oil tree modified floor produced by the invention not only has the functions of anti-corrosion and biological invasion resistance, the characteristics of aesthetics, durability and environmental protection, but also has stable material, and is not easy to deform and crack. No matter in technical indexes or in functional indexes, the tong-oil tree modified floor is comparable to the solid wood floor produced from natural hardwood tree species.

Description

technical field [0001] The invention relates to a production and processing method of tung tree modified floor, which belongs to the technical field of artificial board product manufacturing. Background technique [0002] At present, the solid wood floors sold on the market in my country are mainly made of broad-leaved tree species in natural forests. Since the country implemented the natural forest protection project and completely banned the logging of natural forest resources dominated by broad-leaved trees, the contradiction between the supply and demand of raw materials for the production of solid wood flooring has become increasingly prominent. , The output of solid wood flooring is declining year by year, while the price has risen sharply. However, fast-growing and high-yielding timbers such as tung tree have been limited in use due to their own shortcoming of soft material due to reasons such as short growth period and physical characteristics of the tree species. Th...
