Abstract

The invention provides a manufacturing method of a plant fiber insect-repelling density board. The preparation method comprises the following steps of (1) preparing materials; (2) manufacturing fiber; (3) soaking the fiber obtained in the step (2) in a flame retardant, and drying the fiber at 95 DEG C after soaking until the water content of the fiber is 40%-50%, wherein a preparation method of the flame retardant comprises the steps that 1.0 part of ammonium polyphosphate is taken and dissolved in 20 parts of water, 0.5 part of dry layered zirconium phosphate is added, the materials are stirred to be uniform, and then turbid emulsion is obtained, (4) coating the dry fiber surface with an adhesive; (5) forming a blank board in the mode of conducting pre-pressing and cutting while conducting laying; (6) feeding the formed blank board into a cold molding machine through a plate loader, and conveying the blank board into a curing chamber through a plate unloader to be cured after cold pressing, and (7) conducting demolding, airing or drying, edge cutting, sanding and thickness fixing in sequence on the cured blank board, and obtaining the plant fiber particle insect-repelling density board. The density board does not release free formaldehyde, is flame retardant, has mosquito-repellent and mothproof performance, and is friendly to the environment and human health.

Description

technical field [0001] The invention relates to the technical field of home wood-based panels, in particular to a plant fiber insect-repelling density board. Background technique [0002] With the popularity of environmentally friendly furniture, wood-based panels have gradually entered thousands of households. Wood-based panels have greatly improved the application rate of wood and are the first material for the current production of furniture and interior decoration. The wood-based panels currently used in furniture mainly include plywood, particle board, and MDF. Among them, the density board is made of wood fiber or other plant fiber, prepared by fiber, applied with synthetic resin, and pressed under the condition of heating and pressure. [0003] It is made by immersing wood, tree branches and other objects in water, then heat-grinding, paving, and hot-pressing. It is an artificial board made of wood fiber or other plant fiber and applied with urea-formaldehyde resin ...
