Embodiment 1

[0039] A high-gloss automotive black film, see figure 1 , from top to bottom is composed of positioning paper 1, glossy coating 2, PVC black film 3, acrylic pressure-sensitive adhesive 4 and release paper 5.

[0040] This positioning paper 1 is used for the temporary protection of the PVC black film 3.

[0041] The formula of this glossy coating 2 is made up of the material of following parts by weight: 43 parts of diethyl p-toluenesulfonyloxymethyl phosphonate, 2.7 parts of tin light stabilizer, 0.25 part of 8% zinc octanoate, propylene glycol methyl ether acetate 5.3 parts, polyisocyanate 29.5 parts, butyl cellulose acetate 8 parts and butanone 14 parts.

[0042] The formula of the acrylic pressure-sensitive adhesive 4 is composed of the following parts by weight: 6 parts of acrylic acid, 26 parts of ethyl acetate, 0.9 part of dibenzoyl peroxide, 41 parts of toluene, 27.5 parts of isooctyl acrylate and crosslinking agent 1.6 servings.

[0043] Wherein, the crosslinking ag...

Embodiment 2

[0056] The high gloss automobile black film of the present embodiment and preparation method thereof are similar to embodiment 1, and its difference is only in:

[0057] The formula of this glossy coating 2 is made up of the material of following parts by weight: 41 parts of diethyl p-toluenesulfonyloxymethylphosphonate, 3 parts of tin light stabilizer, 0.2 part of 8% zinc octanoate, propylene glycol methyl ether acetate 5.5 parts, polyisocyanate 28 parts, butyl cellulose acetate 6 parts and butanone 15 parts.

[0058] The formula of the acrylic pressure-sensitive adhesive 4 is made up of the following parts by weight: 5 parts of acrylic acid, 27 parts of ethyl acetate, 0.8 part of dibenzoyl peroxide, 42 parts of toluene, 25 parts of isooctyl acrylate and crosslinking agent 1.8 servings.

[0059] Wherein, the crosslinking agent is 3-methyltetrahydrothiazole-2-thione.

[0060] The difference between the preparation method of the high-gloss automotive black film provided in th...

Embodiment 3

[0063] The high gloss automobile black film of the present embodiment and preparation method thereof are similar to embodiment 1, and its difference is only in:

[0064] The formula of this glossy coating 2 is made up of the following material in parts by weight: 45 parts of diethyl p-toluenesulfonyloxymethylphosphonate, 2.5 parts of tin light stabilizer, 0.3 part of 8% zinc octanoate, propylene glycol methyl ether acetate 5 parts, polyisocyanate 31 parts, butyl cellulose acetate 9 parts and butanone 13 parts.

[0065] The formula of the acrylic pressure-sensitive adhesive 4 is composed of the following parts by weight: 7 parts of acrylic acid, 25 parts of ethyl acetate, 1 part of dibenzoyl peroxide, 40 parts of toluene, 30 parts of isooctyl acrylate and crosslinking agent 1.4 servings.

[0066] The difference between the preparation method of the high-gloss automotive black film provided in this embodiment and Example 1 is:

Abstract

The invention belongs to the technical field of automobile decoration and particularly discloses a high-glossiness automobile black film and a preparation method therefor. The high-glossiness automobile black film comprises locating paper, a bright coating, a PVC black film, an acrylic pressure-sensitive adhesive and release paper sequentially from top to bottom. A formula of the bright coating isprepared from the following matters in parts by weight: 41-45 parts of diethyl p-toluenesulfonyloxymethylphosphonate, 2.5-3.0 parts of tin photostabilizer, 0.2-0.3 part of 8% zinc caprylate, 5-5.5 parts of propylene glycol methyl ether acetate, 28-31 parts of polyisocyanate, 6-9 parts of butyl acetate cellulose and 13-15 parts of butanone. According to the high-glossiness automobile black film, the glossiness is 90% or more and is close to a mirror face effect, so that the attractiveness of an automobile body is improved, and the vehicle competitiveness is improved; and the weather resistanceand acid / base resistance are good, the scratch resistance, scrub resistance, stone impact resistance and water gun impact resistance are greatly improved, and the service life of the high-glossinessautomobile black film is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile decoration, and in particular relates to a high-gloss automobile black film and a preparation method thereof. Background technique [0002] Black film, also known as black film, is a kind of functional car film. It is used on the inner and outer frames of the car, the driver's window, the body and other parts. The car with black film installed is obviously more vivid than the car body curve without black film, with a strong sense of design, and the visual effect of the car window and driving window is increased, natural and generous, and has a good decorative effect , more importantly, it has a breathable functional role. [0003] Most of the existing high-gloss automotive black films have the following defects: 1) the gloss is lower than 90%, and the mirror effect cannot be approached. The car body after the film is not beautiful enough, and the vehicle market competitiveness is small; Stone...
