Zero-carbon high-fiber environment-friendly sheet synthesized by waste circuit board powder and production process thereof

Abstract

The invention discloses a zero-carbon high-fiber environment-friendly sheet synthesized by waste circuit board powder and a preparation process thereof. The pressing raw materials of the environment-friendly sheet comprise: circuit board recycled powder, wood fiber powder, a cross-linking agent, a waterproofing agent, and carbon filament fiber; the production process of the sheet comprises the following steps of: drying the circuit board recycled powder at a constant temperature; converting high fiber auxiliary materials into wood fiber powder above 80 meshes, drying, and then stirring under 180 DEG C to form carbon fiber powder; adding a processing assistant and blending uniformly again; and feeding materials, paving pressing plates, pressurizing, standing, complementing pressure, and gently decompressing to produce the sheet. The pressure during the production process is controlled so that the sheet is stable in quality and high in intensity; the sheet synthesized by wood fiber powder obtained by recycling crop straw, bamboo and wood saw powder and the like with the waster circuit board powder can be sawn, drilled, processed, and shaped easily; furthermore, the sheet is excellent in waterproof and fireproof performances, and high in static bending strength; and the utilization of waste materials reaches the purposes of environmental protection and low carbon.

Description

technical field [0001] The invention relates to an environment-friendly plate, in particular to a zero-carbon high-fiber environment-friendly plate synthesized by using waste circuit board powder. The invention also relates to a manufacturing process of a zero-carbon high-fiber environment-friendly board synthesized by using waste circuit board powder. Background technique [0002] The raw material of traditional wooden boards is wood, which needs to cut down forest resources, resulting in soil erosion, various natural disasters, affecting the balanced development of the natural environment and ecology, not environmentally friendly and unable to effectively save energy and reduce emissions. This kind of wood product board releases a large amount of formaldehyde, and it is easy to swell, deform, bend, and mold when exposed to water. It is not resistant to corrosion, acid, and alkali, and is flammable. [0003] With the rapid development of cities around the world, a large am...
