Embodiment 1

[0038] combine figure 1 , a process of pure solid wood or log special-shaped wood moldings hot-pressed and impregnated with film decorative paper in this embodiment. Suitable moulding-based substrates and base papers for impregnated laminated decorative papers.

[0039] For the base paper impregnated with film decorative paper, it is made of pure virgin pulp, because the wood fiber of pure virgin pulp is relatively long, which is conducive to the extension of the paper. For the paper made of secondary or tertiary recycled paper beating, the wood fiber is reused. The fibers are very short, and this type of short-fiber paper can cause breakage or other problems after heat pressing, so it is not recommended. At the same time, in order to meet the subsequent use of hot pressing and improve the quality of the product, the thickness of the decorative paper needs to be increased compared with the traditional decorative paper, and the general paper thickness is 70-110g / m 2 It is b...

Embodiment 2

[0055] The process of hot-pressing and impregnating film decorative paper for pure solid wood or logs with special-shaped wood moldings in this embodiment is basically the same as that in Embodiment 1, except that the thickness of the decorative paper used in this embodiment is 70g / m 2 , the paper thickness is relatively thin, when impregnating the decorative paper, the impregnating temperature is 100°C, the vehicle speed is 12m / s; the amount of glue applied is 140%, and the volatility of the impregnated film decorative paper is 7%. In this embodiment, when the wood strips and the impregnated film decorative paper are hot-pressed, the temperature of the hot press in step (1) is 120°C; in step (2), when the mold is completely closed, the impregnated film decoration The paper stays for 3 seconds under the condition of temperature but no pressure; in step (3), the hot pressing pressure is 2kg / m 2 , and keep the pressure for 30 seconds.

Embodiment 3

[0057] The process of hot-pressing and impregnating film decorative paper for pure solid wood or logs with special-shaped wood moldings in this embodiment is basically the same as that in Embodiment 1, except that the thickness of the decorative paper used in this embodiment is 110g / m 2 , the paper thickness is thicker, when impregnating the decorative paper, the impregnating temperature is 160°C, the vehicle speed is 28m / s; the amount of glue applied is 170%, and the volatility of the impregnated film decorative paper is 9%. In this embodiment, when the wood strips and the impregnated film decorative paper are hot-pressed, the temperature of the hot press in step (1) is 200°C; in step (2), when the mold is completely closed, the impregnated film decoration The paper stays for 20 seconds under the condition of temperature but no pressure; in step (3), the hot pressing pressure is 8kg / m 2 , and keep the pressure for 80 seconds.

Abstract

The invention discloses a process of hot-pressing dipped glue film decorative paper on pure solid wood or raw wood allomorphia balansae line, and belongs to the field of solid wood line hot-pressing. The process comprises the following steps: (1) placing dipped glue film decorative paper and a wood line on a lower die of a hot press, and preheating the dipped glue film decorative paper; (2) slowly lifting the lower die, maintaining the dipped glue film decorative paper for 3-20 seconds without pressure but temperature when the die is completely closed, so that the dipped glue film decorative film is sufficiently softened; (3) completely closing the lower die and an upper die, and maintaining the pressure for 30-80 seconds when the hot-press pressure is 2-8kg/sq.m.; and (4) after finishing the pressure maintaining, slowly descending the lower die, taking out the work-pieces and subsequently cleaning. According to the process disclosed by the invention, the technical problem of hot-pressing dipped glue film decorative paper on the pure solid wood or raw wood allomorphia balansae line is overcome, and a transformation and upgrading historic revolution is brought for the wood line industry; and meanwhile, the precious wood is replaced by affordable wood, and the work-piece cost is reduced.

Description

technical field [0001] The invention relates to a process for hot-pressing and impregnating film decorative paper with wood strips, more specifically, to a process for hot-press and impregnating film decorative paper for pure solid wood or log special-shaped wood strips. Background technique [0002] Mold moldings are essential furniture in the field of home decoration and tooling, and are widely used in cabinets, doors and windows, tables and chairs, etc. With the continuous development of the economy and the continuous needs of people, there are more and more material pursuits. The texture of precious wood species (sandalwood, huanghuali, etc.) can give people better visual enjoyment, so it has been widely sought after. , but these precious wood species are scarce at present, and the price is high, which is unaffordable for ordinary families. After decorating the decorative paper with the texture of precious wood species on the surface, it can give ordinary materials the ...
