Problems solved by technology
[0003] Nowadays, in the production process of particleboard, most of the particleboards are hot-pressed with isocyanate glue on a multi-layer press. Using this process to produce particleboards, the output is relatively low, and it has been difficult to achieve the current increasing demand for formaldehyde-free particleboards. demand

The invention discloses a production method of a formaldehyde-free shaving board. The production method comprises the following steps that the measured plate surface layer material and the prepared plate core layer material are obtained; an isocyanate adhesive is selected as an adhesive to apply glue to the material of the surface layer material and the prepared plate core material; a tackifier and process water are added to the surface layer material of the preparation plate; glue mixing treatment is carried out on the surface layer material and the material of the prepared plate core layer material; a paving machine is sent into the prepared plate surface layer material and the plate making core layer material subjected to glue mixing treatment; pre-pressing operation is carried out on the prepared plate surface material and the prepared plate core layer material processed by the paving machine to form a shaving board blank; and the shaving board blank subjected to pre-pressing operation is sent into a continuous press for hot-pressing treatment. Compared with the prior art, the production method of the formaldehyde-free shaving board is provided, the production quality of the formaldehyde-free shaving board can be guaranteed, the production time of the formaldehyde-free shaving board is shortened, and the production efficiency of the formaldehyde-free shaving board is remarkably improved.
Description
technical field [0001] The present application relates to the technical field of building material manufacturing, and more specifically, relates to a production method of formaldehyde-free particleboard. Background technique [0002] Particleboard is a wood-based panel made of wood or other lignocellulosic materials. After applying adhesives, it is glued together under heat and pressure. It is a common type of wood-based panels. In industrial production, the main raw material of particleboard is wood or wood processing waste. A key process in the production process of particleboard is the hot pressing of particleboard. The blank is consolidated into a plate of specified thickness after being pressurized. [0003] Nowadays, in the production process of particleboard, most of the particleboards are hot-pressed with isocyanate glue on a multi-layer press. Using this process to produce particleboards, the output is relatively low, and it has been difficult to achieve the curren...
