Embodiment 1

[0025] Embodiment 1 A kind of thickness is 18mm Juncao fiberboard and preparation method thereof

[0026] Cutting: Cut the 1.5-year-old Oasis No. 1 Juncao with a water content of 50.2% to a length of 2-3cm;

[0027] Cooking: After cutting, the Juncao is boiled and softened under high pressure; the cooking temperature is controlled to be 158-160°C, the steam pressure is 5.0-5.5bar, and the cooking time is 2-3min;

[0028] Defibrillation and sizing: the cooked Juncao is mechanically decomposed into fibers in a thermal mill; in the process of ejecting fibers from the thermal mill, an adhesive is added to obtain sizing Juncao fibers; the addition of adhesive The amount is 10% urea-formaldehyde resin of the quality of the cooked Juncao;

[0029] Drying: Use a flash dryer to air dry the sizing Juncao fiber at 120-160°C, and the moisture content of the dried Juncao fiber is 8.05%;

[0030] Paving, sweeping and pre-pressing: the dried Juncao fibers are paved, smoothed and pre-presse...

Embodiment 2

[0037] Embodiment 2 A kind of thickness is 12mm Juncao fiberboard and preparation method thereof

[0038] The difference from Embodiment 1 is that in this embodiment:

[0039] Cutting: Cut the 2-year-old Oasis No. 1 Juncao with a water content of 59.5% into a length of 2-3cm;

[0040] Cooking: soften the cut Juncao by high-pressure cooking; the cooking temperature is 158-160°C, the steam pressure is 5.0-5.5bar, and the cooking time is 2-3min;

Abstract

The invention relates to a preparation method of a Juncao fiberboard. The preparation method comprises the following steps: cutting: cutting a 1-2-year-old Juncao with a water content of 50-70% into a length of 2-3 cm to obtain a cut Juncao Cooking: the Juncao after the cutting is softened by high-pressure cooking to obtain the Juncao after the cooking; Defibrating and sizing: the Juncao after the cooking is mechanically decomposed into fibers; adding an adhesive to obtain the bacteria after the sizing. Grass fiber; drying: drying the sizing Juncao fiber at 120-160 ° C to obtain the dried Juncao fiber; paving and pre-pressing: paving, sweeping and pre-pressing to obtain a Juncao fiber slab, heat Pressing: hot pressing the Juncao fiber slab to obtain the Juncao fiberboard. As the raw material of the Juncao fiberboard, low-cost and fast-growing Juncao is used instead of wood chips, the preparation process is simple, and it is easy to popularize, and the obtained fiberboard has excellent indicators and is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of fiberboards, in particular to a Juncao fiberboard and a preparation method thereof. Background technique [0002] my country is the world's largest production base and exporter of wood-based panels, and the annual demand for wood far exceeds the production of wood. As an indispensable means of production and living, wood-based panel products play an important role in the national economy and people's material life. In recent years, with the reduction of forest resources and the improvement of environmental protection awareness, industrial production is bound to save wood resources as much as possible, and the production and use of wood-based panels is one of the main ways to save and efficiently utilize wood resources. [0003] The main raw materials of fiberboard are wood and wood processing residues or other non-wood raw materials, which are processed into fibers, and hot-pressed with adhesives and oth...
