Embodiment 1

[0023] Embodiment 1: a kind of preparation method of thermal transfer printing silica gel film of the present invention, it comprises the following steps:

[0024] (1) Select a hot-melt adhesive film that melts between 120°C and 150°C;

[0025] (2) Prepare the coating silica gel, which is made by mixing the following components in parts by mass: 90 parts of two-component addition type liquid silica gel, 0.01 part of aluminate coupling agent, hydroxyhydrocarbyl modified polysiloxane 2-5 parts of alkane, 0.5 parts of linear methyl hydrogen silicone oil, 0.005 parts of platinum catalyst, 2-5 parts of epoxy modified silicone resin, 2.5 parts of toluene;

[0026] (3) Use a coating machine to coat the coating silica gel on the hot melt adhesive film to a thickness of 5-10 filaments, and dry it in an oven to obtain a thermal transfer printing silica gel film.

[0027] The hot melt adhesive film is a polyurethane film, and the thickness of the polyurethane film is 0.2 mm to 0.5 mm. ...

Embodiment 2

[0034] Embodiment 2: This embodiment is substantially the same as Embodiment 1, except that the coating silica gel is made by mixing the following components in parts by mass: 90 parts of two-component addition type liquid silica gel, aluminate 0.01 part of joint agent, 2 parts of hydroxyhydrocarbyl modified polysiloxane, 0.5 part of linear methyl hydrogen silicone oil, 0.005 part of platinum catalyst, 5 parts of epoxy modified silicone resin, and 2.5 parts of toluene.

Embodiment 3

[0035] Example 3, this example is basically the same as Example 1, except that the coating silica gel is made by mixing the following components in parts by mass: 90 parts of two-component addition type liquid silica gel, aluminate coupling 0.01 parts of agent, 3 parts of hydroxyhydrocarbyl modified polysiloxane, 0.5 parts of linear methyl hydrogen silicone oil, 0.005 parts of platinum catalyst, 3 parts of epoxy modified silicone resin, and 2.5 parts of toluene.

[0036] The heat transfer printing silicone film of the present invention is a composite film of silica gel and hot melt adhesive, which not only solves the problem of low efficiency when hot melt adhesive is used in current heat transfer printing, but also solves the problem of low efficiency when the silicone film is directly printed on ordinary heat transfer printing. The problem of poor printing firmness on the melt adhesive film allows silicone printing to be used for heat transfer printing in large quantities.

Abstract

The invention discloses a preparation method of a heat-transfer printing silicone film; the preparation method comprises the steps of (1) selecting hot-melt film, and melting the hot-melt film at 120 DEG C to 150 DEG C; (2) blending coating silicone that is made by mixing, by weight, 90 parts of bicomponent additional liquid silicone, 0.01 part of aluminate coupler, 2-5 parts of hydroxyalkyl modified silane, 0.5 part of linear methyl hydrogen silicone oil, 0.005 part of metal platinum catalyst, 2-5 parts of epoxy modified silicon resin, and 2.5 parts of toluene; (3) applying coating silicone to the hot-melt film to 5-10 si in thickness, and the heat-transfer printing silicone film is prepared by drying. Heat-transfer printing silicone film and application thereof are also disclosed. The problem that efficiency is low since hot-melt silicone used in current heat-transfer printing ins only suitable for single-sheet printing is solved, the problem that print durability is poor due to silicone being directly on common hot-melt silicone film is also solved, and silicone printing is suitable for batched heat-transfer printing.

Description

technical field [0001] The invention relates to the field of screen printing, in particular to a method for preparing a heat transfer printing silica gel film, an application of the heat transfer printing silica gel film and the heat transfer printing silica gel film. Background technique [0002] In the field of printing, silicone printing has been favored and recognized by more and more users because of its environmental protection, soft touch and various effects, and its market share has steadily increased. However, compared with conventional glue printing, due to the slower printing speed and lower efficiency, the market share of silicone printing is still small, so technology development and production process upgrading are relatively slow. [0003] At present, the printing field is in the process of shifting from manual production to semi-automatic production. Since the substrates for silicone printing vary greatly, and the demand is generally not very large, in order...
