Problems solved by technology

Paintings and calligraphy works mounted with traditional adhesive materials tend to get moldy; however, the current ordinary adhesive film for mounting is expensive, difficult to mount, uneven in thickness distribution, wastes human resources for a long time for mounting, and is easy to install when mounting. Wrinkles, uneven mounting works, existing domestic and foreign adhesive materials will permeate after a long time of mounting, affecting the effect and quality of mounting

Embodiment Construction

[0015] The structure of the present invention and its preparation process will be further described in detail below in conjunction with the accompanying drawings.

[0016] The double-sided hot-melt adhesive film has the following structure: the two sides of the paper layer 1 are coated with a hot-melt adhesive layer 1 2 and a hot-melt adhesive layer 2 3 . The raw material used for the hot-melt adhesive layer 1 2 and the hot-melt adhesive layer 2 3 is ethylene-vinyl acetate copolymer resin, namely EVA28.150. The thickness of the paper layer 1 is 0.001mm-0.6mm. The thickness of the hot-melt adhesive layer-2 and the hot-melt adhesive layer-2 3 is 0.001-0.1mm.

[0017] The preparation process of the above-mentioned double-sided hot-melt adhesive film includes the following process steps: heating the used hot-melt adhesive ethylene-vinyl acetate copolymer resin, namely French EVA28.150, to 120°C or 140°C or 160°C, and heating the heated Put the hot melt adhesive into the hot glue...

Abstract

The invention discloses a double-side hot-melt adhesive film and process for preparation, wherein the two surfaces of the paper layer are coated by hot melt glue layers. The preparing process comprises heating the hot melt glue to 120-160 deg. C, coating the glue to the two sides of paper, finally press forming.

Description

Technical field [0001] The invention relates to a hot-melt adhesive film, in particular to a double-sided hot-melt adhesive film suitable for painting and calligraphy mounting. Background technique [0002] Painting and calligraphy works must be framed to facilitate hanging, displaying, appreciating and collecting. The level of mounting technology and the selection of mounting materials directly affect the artistic effect and collection value of calligraphy and painting works, especially whether the adhesive material is suitable or not has a greater impact on the effect and value of the final mounted work. Therefore adhesive material is an indispensable product in mounting technology. Paintings and calligraphy works mounted with traditional adhesive materials tend to get moldy; however, the current ordinary adhesive film for mounting is expensive, difficult to mount, uneven in thickness distribution, wastes human resources for a long time for mounting, and is easy to instal...
