Problems solved by technology

However, whether it is manual edge banding or edge banding with an automatic edge banding machine, it is necessary to do some complicated preparations before pasting, such as heating and melting of hot melt adhesive, cleaning of edge banding strips, and whole materials; It works in two stages, which will consume more gluing materials, and the amount of gluing materials will not only be large but also uneven. Therefore, not only will overflow glue occur during edge sealing, but at the same time There will also be glue seams at the joint between the glue layer and the board surface, so that it is necessary to clean up the glue overflow after the event, and the glue seams that appear after the edge banding will also cause unsightly appearance of the finished product

Abstract

The invention relates to the technical field of paper-plastic edge bandings with hot-melt adhesives, in particular to a paper-plastic edge banding with a hot-melt adhesive and a preparation process for the paper-plastic edge banding. The paper-plastic edge banding with the hot-melt adhesive sequentially comprises a protective layer, a decorative layer, a paper-plastic substrate layer and a hot-melt adhesive layer from top to bottom, wherein the lower surface of the paper-plastic substrate layer is blade-coated with the hot-melt adhesive layer. According to the paper-plastic edge banding with the hot-melt adhesive, the hot-melt adhesive layer is combined, the paper-plastic substrate layer is adhered to and seamlessly connected with the hot-melt adhesive layer in a molten state, and the adhesion force of the hot-melt adhesive layer with the paper-plastic substrate layer and a product to be banded is high, so that the phenomenon of degumming is avoided; in addition, when the paper-plastic edge banding is used, adhesive overflow, the formation of an adhesive line and preparation work during the sticking of a conventional edge banding can be avoided, the effects of reducing the using amount of the adhesive and avoiding adhesive overflow during sticking, the adhesive line and tedious preparation are achieved, and the quality of a product and the production efficiency are greatly improved; a preparation method is simple, easy, high in production efficiency and applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of plastic edge banding, in particular to a paper-plastic edge banding with hot melt adhesive and a preparation process thereof. Background technique [0002] Edge banding is a material for protecting, decorating and beautifying the section of furniture panels. Its main function is to seal the section of the panel so as to prevent the panel from being damaged by the environment and unfavorable factors during use. Unique color and texture design and other decorations make the applied furniture panel products more textured and three-dimensional. For edge banding products, gluing treatment is an important process that affects product quality. [0003] At present, in the furniture production process, the adhesive used for bonding the edge strip to the board is mainly hot melt adhesive. The traditional edge banding is co-extruded into one body. In the existing furniture edge banding process, there are two bondi...
