Production method for scientific and technological ecological impregnated paper

Abstract

The invention discloses a production method for scientific and technological ecological impregnated paper. The method is sequentially carried out according to the following steps: preparing urea-formaldehyde glue; preparing triamine glue; carrying out primary impregnation; carrying out primary drying; carrying out coating; carrying out secondary impregnation; carrying out secondary drying; carrying out tailoring; carrying out inspection; carrying out packaging; and putting the paper in storage. The scientific and technological ecological impregnated paper prepared by virtue of the method can fully replace wood veneer for veneer manufacture of an ecological board and eliminate adverse effect caused by wood veneer in a home decoration process, so that the integral quality level of the ecological board is improved. Compared with the impregnated paper prepared from urea-formaldehyde glue and triamine glue, the impregnated paper disclosed by the invention is high in impact resistance and wear resistance, low in content of free formaldehyde, smooth and uniform in distribution of glue, and can fully cover the texture of the board, so that the bottom exposing and carbonizing phenomena are eliminated, the yield of a product is improved and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of scientific and technological ecological impregnated paper. Background technique [0002] At present, the custom-made furniture in the home improvement market mostly uses ecological panels as the main material for processing, while the veneer of the ecological panels uses veneer to improve the flatness and covering effect of the surface. The veneer plays a key role in the overall decorative effect of the panels. Due to the natural characteristics of wood, there are some insurmountable defects in veneer. The wood fibers only have tension in the direction of tree growth (longitudinal), and there is almost no tension in the transverse direction. As a result, the board will crack longitudinally during use. Secondly, the sag on the surface of the wood fiber itself, in the process of pressing, will appear incompletely pressed locally, which is manifested as carbonization of ...

AI Technical Summary

Problems solved by technology

Due to the natural characteristics of wood, there are some insurmountable defects in the veneer. The wood fibers only have tension in the direction of tree growth (longitudinal), and there is almost no tension in the horizontal direction, resulting in longitudinal cracking of the board during use.

Secondly, the sag on the surface of the wood fiber itself, in the process of pressing, will appear incompletely pressed locally, which is manifested as carbonization of the board surface, which affects the choice of color on the board surface. You can only choose light colors instead of dark colors, resulting in Choices are limited

Furthermore, due to the fact that the veneer's own scars and black lines are difficult to completely cover and the surface tension is limited, there will be bottom-through phenomenon and surface unevenness during the pressing process, which will have a great impact on the appearance of the surface and bring bad effects to home decoration.

In addition, in the production of veneer, a large amount of wood is used, which has a considerable adverse impact and waste on the country's ecological environment and forest resources.
