Problems solved by technology

However, due to the poor adhesion of domestic hot stamping adhesives, it is prone to hot stamping flying gold, paste, etc., and on the surface of many materials coated with silicone oil or wax that is difficult to stick to the surface, the hot stamping properties of hot stamping adhesives are affected. Larger limitations, which force most manufacturers not to purchase expensive imported rubber, increasing production costs
In addition, as the demand for anodized aluminum materials continues to increase, the hot stamping technology of anodized aluminum is also promoted to develop at a high speed. Traditional hot stamping adhesives are also prone to hot stamping defects during high-speed hot stamping.

preparation example Construction

[0027] Embodiments of the present invention also provide a preparation method of anodized aluminum hot stamping glue, comprising the following steps:

[0028] (1) prepare materials by weight;

[0029] (2) After dissolving the styrenic thermoplastic elastomer, the tackifying resin and the auxiliary resin, obtain the styrenic thermoplastic elastomer solution, the tackifying resin solution and the auxiliary resin solution respectively, and then dissolve the styrenic thermoplastic elastomer solution , tackifying resin solution, additive resin solution and fumed silicon dioxide are uniformly mixed to obtain a finished product.

[0030] In the present invention, when the tackifying resin is dissolved, the dissolving temperature is 40-70° C. to ensure that the tackifying resin can be fully dissolved.

[0031] In the present invention, the styrene-based thermoplastic elastomer and the auxiliary resin may be dissolved at room temperature.

[0032] In the present invention, when disso...

Embodiment 1

[0037] Example 1 of the present invention provides an anodized aluminum hot stamping glue, which includes the following components in parts by weight: 40 parts of C9 petroleum resin, 10 parts of SBS, 5 parts of vinyl chloride resin and 8 parts of fumed silica.

[0038] The anodized aluminum hot stamping glue is prepared by the following method:

[0039] (1) Under the condition of constant stirring, add C9 petroleum resin to the toluene solution, heat the mixture to 40°C, and stir at 300r / min for 30-60min until the C9 petroleum resin is completely dissolved to obtain C9 resin solution;

[0040] (2) Under the condition of constant stirring, add SBS to the toluene solution, and stir at 300r / min at room temperature for 30-60min until the SBS is completely dissolved to obtain the SBS solution;

[0041] (3) Under the condition of constant stirring, add chloroacetic resin to the mixed solvent of butanone and toluene (the volume ratio of butanone and toluene is 1:1, the same below), ...

Embodiment 2

[0045] Embodiment 2 of the present invention provides a kind of anodized aluminum hot stamping glue, comprises the following components by weight: 45 parts of C9 petroleum resin, 15 parts of SBS, 10 parts of vinyl chloride resin, 5 parts of rosin and 10 parts of fumed silica .

[0046] The preparation method of the anodized aluminum hot stamping glue is the same as that in Example 1, the difference is that: under the condition of constant stirring, rosin is added to the ethyl acetate solution, the mixed solution is heated to 40 ° C, and at 300 r / Stir for 30 to 60 minutes at a speed of 1 min until the rosin is completely dissolved to obtain a rosin solution; then, under constant stirring, add C9 resin solution, SBS solution, vinyl chloride resin solution, rosin solution and fumed silica to methyl ethyl ketone In a mixed solvent with toluene, adjust the solid content to 20%, and stir at 300r / min for 30-60min at room temperature to obtain the finished product.

Abstract

The invention discloses an alumite hot stamping adhesive. The alumite hot stamping adhesive is prepared from components in parts by weight as follows: 10-20 parts of a styrene thermoplastic elastomer,40-65 parts of tackifying resin, 5-25 parts of auxiliary resin and 8-18 parts of fumed silica. Due to addition of the styrene thermoplastic elastomer, the alumite hot stamping adhesive has good bonding performance and thermoplasticity at high temperature, the added tackifying resin can provide better initial viscosity, and the auxiliary resin can enhance adhesion to an aluminum layer. Under the synergistic effect of the styrene thermoplastic elastomer, the tackifying resin and the auxiliary resin, the hot stamping adhesive has proper softening point to meet high-speed hot stamping, good adhesion performance and certain temperature resistance; the added fumed silica improves the appearance effect and the hot stamping effect of the hot stamping adhesive. The invention also provides a preparation method of the alumite hot stamping adhesive.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anodized aluminum hot stamping glue and a preparation method thereof. Background technique [0002] Anodized aluminum is a new type of packaging material for vacuum aluminum plating. After a certain temperature and pressure, the pre-engraved patterns, lines and fonts on the hot stamping plate are transferred to the surface of the substrate, making it bright in color, strong in metal feeling, visually It has been widely used in hot stamping and decoration on the surface of paper products, plastic products, leather products, wood products and so on. The anodized aluminum structure generally consists of a hot stamping adhesive layer (adhesive layer), an aluminum layer, a holographic pattern layer, a release layer (isolation layer) and a base film layer. Anodized aluminum hot stamping is to make the hot stamping adhesive layer and release layer of anodized a...
