Problems solved by technology

[0002] In recent years, the information of using reed as the main raw material to produce building boards has been continuously updated, but there seem to be many defects; cement, gypsum, reed fiber composite materials and production methods (CN96116216.3), with cement or gypsum as cementing raw materials, also include Filling materials, additives and water, cement or gypsum account for 35-45%. Although the boards made can replace wood boards, they are still heavy in weight. During the production process, cement or gypsum will cause environmental pollution and worsen production conditions; In the board composition of the prefabricated board and its manufacturing method (CN85108738) with broken reed rods as the main raw material, the second layer is impregnated with asphalt material, which pollutes the environment. The production process is more complicated, and the raw material Reed shavings and reed rods are used, so the strength of the board is low; the laminated reed compression board (CN94214644.1) is composed of the reed layers fixed and connected by sewing and cross-linking the bottom thread rope and the weft thread rope, and the production process is complicated. Can only cover the top of the layer; reed rubber board and its processing technology (CN200310118472.9) The reed blanks of the criss-crossed reed curtain are woven with warp threads at a distance of 100-500mm, the thread weaving process is cumbersome, and the board strength is not high

Embodiment 1

[0017] First, dehydrate and dry the raw reeds, or dry them in the air, so that the water content is less than 1%; then enter the pretreatment process, and send the reeds to a self-made double-roller for rolling, which can be rolled once or rolled Press 2 or 3 times; before rolling, the tubular reed stalk should be broken into two halves that are connected together, and then the reed stalk will be peeled, tipped and softened through the double-roller machine, and the reed softened by the double-roller machine will form Sheet-shaped, or thick and thin fibers, long strip-shaped blanks connected to each other; in the glue spraying process, the surface of the blank is sprayed with phenolic resin glue with a spray gun, and the amount of glue used is controlled at 0.2 kg of the total amount of blanks per kilogram ;The surface layer raw material adopts 120g facial paper with colored patterns; or, adopts 0.6mm thick wood veneer; After the first layer of glue spraying, transfer to the s...

Embodiment 2

[0019] The raw reeds are dried to make the water content <1%. The reason is to ensure that the board does not foam during the pressing process; the glue spraying process uses urea-formaldehyde resin; ;The surface layer is made of 180g color pattern paper, or 1mm thick wooden skin; the blank layer has 26 layers in total, and the thickness of the formed plate is 15mm; Control at 240°C for 8 minutes; other process conditions are the same as in Example 1, and qualified reed boards can also be produced.

Embodiment 3

[0021] Reeds are used to produce composite panels for decoration. After the reeds are dehydrated, pretreated, and sprayed with glue, they enter the shaping process, and the blanks are compiled into a reed mat shape, with a total of 50 layers arranged up and down, and the thickness of the board is 30mm; the colored kraft paper for the surface layer is 220g, or 2mm thick wooden skin; The pressing process presses 4 boards at a time, the pressure is 60T, the temperature is 260° C., and the time is controlled at 10 minutes; other process conditions are the same as in Example 1, and qualified reed boards can also be produced.

Abstract

The invention relates to a method for producing bulrush sheet, belonging to the production of construction decorate sheet, which can solve the defects of present technique that complex processes and worse strength. Wherein, it is characterized in that: after the pretreatment on the bulrush blank, entering into the step of spraying pastern, while the pastern amount is 0.2kilogram of 1 kilogram of total blank; entering into the shaping step that arranging the blank rod and head on the aluminum plate with surface layer, while the upper and lower layers are alternated, or each layer of blank is woven into reed mat, while the layer number is 10-50; the pressure at compressing process is 10-60T, while the temperature is 190-260Deg. C and the time is 3-10mins. The invention can be widely used in construction decorate industry.

Description

technical field [0001] The reed board production process of the present invention relates to the building decoration board production industry, that is, a production process method of using reed instead of wood, wood shavings and sawdust to produce decorative boards. Background technique [0002] In recent years, the information of using reed as the main raw material to produce building boards has been continuously updated, but there seem to be many defects; cement, gypsum, reed fiber composite materials and production methods (CN96116216.3), with cement or gypsum as cementing raw materials, also include Filling materials, additives and water, cement or gypsum account for 35-45%. Although the boards made can replace wood boards, they are still heavy in weight. During the production process, cement or gypsum will cause environmental pollution and worsen production conditions; In the board composition of the prefabricated board and its manufacturing method (CN85108738) with br...
