Problems solved by technology

Gel refills, marker pens, and whiteboard pens are generally made of PP. The existing adhesive used for the thermal transfer film of the aluminized process made of PP consists of two layers of glue. Aluminum and ink coloring layer have a protective layer with bonding force, and then apply a layer of PP glue to combine it with the PP base material. The film and the transferred pen holder will lose their adhesion after being placed for a period of time, resulting in product failure

Embodiment 1

[0043] Add 40 parts of 25% 836 type adhesion promoting resin solution to the batching kettle, 15 parts of 30% BM11 type modified acrylic resin solution, 5 parts of 15% EVA-210 type resin solution, 5 parts of 10% Aldehyde and ketone resin solution with a softening point of 90°C, 15 parts of toluene, 15 parts of ethyl ester, 5 parts of fumed silica-based anti-adhesive powder, then start the electric mixer at a speed of 1800 rpm, and stir for 25 minutes.

Embodiment 2

[0045] Add 25 parts of 30% 16-LP resin solution, 30 parts of 20% A-1092 resin solution, 8 parts of 10% EVA-150W solution, 15 parts of toluene, 15 parts of methyl ethyl ketone, 6 parts One part of fumed silica, one part of polyethylene wax, start the electric mixer at 2500 rpm, and stir for 30 minutes.

Embodiment 3

[0047] Add 60 parts of toluene, 15 parts of methyl ethyl ketone, 10 parts of ethyl ester, 6 parts of 526LP resin, 3 parts of EVA-250 resin, 3 parts of ZJ-104 resin, 2 parts of aldehyde and ketone resin, 1 part of For polyethylene wax, start an electric mixer at a speed of 10,000 rpm and stir for 80 minutes.

[0048] Take the glue prepared in Example 1 and carry out gravure coating, the coating line is 150 lines, the machine speed is 80m / min, open four groups of 85 degree ovens, and apply the local aluminized process heat transfer film of the PP glue to the PP material The pen holder is thermally transferred. The temperature of the rubber wheel of the hot stamping machine is 240 degrees. The pressure of the rubber wheel is moderate.

[0049] Place the partial aluminized heat transfer film coated with glue in a 50-degree oven for 30 days to accelerate aging, and then hot-stamp for inspection, and no pattern falls off.

Abstract

The invention relates to PP (polypropylene) glue for a local aluminum plating process heat transfer film. The glue is prepared from raw materials in parts by weight as follows: 40-80 parts of adhesion promoting resin, 40-80 parts of ethylene-vinyl acetate resin, 10-30 parts of modified acrylate resin, 0-20 parts of phenolic resin, 0.5-10 parts of an anti-sticking aid and 60-90 parts of an organic solvent. Compared with the prior art, the glue has the advantages as follows: the glue has the good adhesion for a PP base material, has the high binding force with an aluminum layer and an ink coloring layer, can be applied to back gum of the aluminum plating process heat transfer film and is not required to be treated with the process that a PP aluminum plating process heat transfer film is required to be coated with a glue layer after being coated with a protecting layer.

Description

technical field [0001] The invention belongs to the field of heat transfer printing, and in particular relates to a PP glue used for a heat transfer film in a partial aluminizing process. Background technique [0002] Thermal transfer printing is a relatively new printing process, which consists of a printing carrier (usually PET biaxially oriented polyester film), a release layer, an ink layer, and an adhesive layer, and then passes through a hot stamping machine at a certain temperature, The pressure will peel off the release layer and the ink layer from the printing carrier, and the ink will be firmly attached to the transferred substrate through the bonding effect of the hot melt adhesive. This technology is widely used in industries such as daily necessities, cosmetics, engine oil drums, and decorative panels for building materials. [0003] The thermal transfer film of the local aluminum plating process uses the method of vacuum evaporation to obtain a metal effect on...
