Embodiment 1

[0017] After drying the mountain palm leaf sheath fiber to a moisture content of 10, cut it into squares according to requirements, and put it into an environment with an air humidity of 60 and a temperature of 18 degrees Celsius and store it for later use. Put urea-formaldehyde resin with a solid content of 40% in a closed container, with a viscosity of 1.48 and a pH of 8, add distilled water at a temperature of 30 degrees Celsius to dilute the solution concentration to 20%, and stir until no suspended matter is observed. Put the mountain palm leaf sheath fiber into the urea-formaldehyde solution, keep the pressure of the airtight container at 8Mpa, soak for 60 minutes, drain the mountain palm leaf sheath fiber and let it stand for 10 minutes after soaking, then put the mountain palm leaf sheath fiber into the oven, Bake at a temperature of 88 degrees Celsius for 75 hours. After the baking is completed, stop heating. When the temperature of the oven is naturally cooled to 30 d...

Embodiment 2

[0019] After drying the mountain palm leaf sheath fiber to a moisture content of 15%, cut it into squares according to the requirements, and store it in an environment with an air humidity of 65% and a temperature of 20 degrees Celsius for later use. Put urea-formaldehyde resin with a solid content of 45% in a closed container, with a viscosity of 1.49 and a pH of 8.03, add distilled water at a temperature of 35 degrees Celsius to dilute the solution concentration to 25%, and stir until no suspended matter is observed. Put the mountain palm leaf sheath fiber into the urea-formaldehyde solution, keep the pressure of the airtight container at 10Mpa, soak for 45 minutes, drain the mountain palm leaf sheath fiber and let it stand for 12 minutes after soaking, then put the mountain palm leaf sheath fiber into the oven, Bake at a temperature of 90 degrees Celsius for 73 hours. After the baking is completed, stop heating. When the temperature of the oven is naturally cooled to 32 degr...

Embodiment 3

[0021] After drying the mountain palm leaf sheath fiber to a moisture content of 20%, cut it into squares according to the requirements, and put it into an environment with an air humidity of 70% and a temperature of 18 degrees Celsius for storage until use. Put urea-formaldehyde resin with a solid content of 50% in a closed container, with a viscosity of 1.50 and a pH of 8.03, add distilled water at a temperature of 40 degrees Celsius to dilute the solution concentration to 30%, and stir until no suspended matter is observed. Put the mountain palm leaf sheath fiber into the urea-formaldehyde solution, keep the pressure of the airtight container at 12Mpa, soak for 30 minutes, drain the mountain palm leaf sheath fiber and let it stand for 15 minutes after soaking, then put the mountain palm leaf sheath fiber into the oven, Bake at a temperature of 92 degrees Celsius for 72 hours. After the baking is completed, stop heating. When the temperature of the oven is naturally cooled to...

Abstract

The invention discloses a process for manufacturing a three-ply board by means of trachycarpus martianus leaf sheath fibers. The process includes the steps that (1) the trachycarpus martianus leaf sheath fibers are clipped after being dried; (2) urea resin is placed in a closed container, distilled water is added to the closed container, and the mixture is uniformly stirred until no suspended matter can be observed; (3) the trachycarpus martianus leaf sheath fibers are placed in urea formaldehyde solutions, steeped and then bled to be stood, then the trachycarpus martianus leaf sheath fibers are baked and cooled; (4) the surface of a rubber wood panel is coated with resin adhesives, processed trachycarpus martianus leaf sheath fiber squares are laid on the resin adhesives in a criss-cross and overlapped mode, then the trachycarpus martianus leaf sheath fibers are covered with another rubber wood panel coated with the adhesives, and cold pressing, hot pressing and standing are carried out. The trachycarpus martianus leaf sheath fibers replace solid wood to be used for manufacturing the three-ply board, the requirements for strength and dimensional stability of artificial boards can be well met, mildewing is not prone to occurrence, a large quantity of timber resources are saved, the deficiency of existing forest resources can be relieved to some extent, and the environment is protected.

Description

technical field [0001] The invention relates to a manufacturing process of a plywood, in particular to a manufacturing process of a mountain palm leaf sheath fiber plywood. Background technique [0002] Forest resources are the basis of biodiversity and one of the most important resources on earth. It can not only provide abundant and valuable wood materials and raw materials for human life and production, but also provide many kinds of goods for economic life. What is most important is that forests can maintain water and soil, regulate climate, alleviate or prevent a series of natural disasters such as hail, drought, flood, and sandstorm. As we all know, my country is a country that is relatively scarce in forest resources. Although artificial afforestation and quota logging have been adopted since the founding of the People's Republic of my country, the forest resource situation has been significantly improved. The demand for wood far exceeds the growth rate of wood, and t...
