Embodiment 1

[0022] 1. Put 6 parts of cyclohexane, 2 parts of heptane, and 0.5 parts of styrene-butadiene rubber in a closed stirrer in parts by mass, stir for 1 hour at 65°C until completely dissolved, and cool to room temperature.

[0023] 2. Transfer the above solution to a dispersing mixer, add 5 parts of butyl acrylate, 3 parts of isodecyl acrylate, 0.8 parts of acrylic resin, and 0.01 part of polyether-modified polydimethylsiloxane, and stir for 30 minutes .

[0024] 3. Add 4 parts of color paste, 0.03 parts of a mixture of 52% polyacrylate and 48% alkylbenzene, and 0.22 parts of α-hydroxyalkyl phenone photoinitiator into the above-mentioned dispersing mixer, stir for 10 minutes, and discharge Instantly.

[0025] 4. Brush the above ink on the side of the clean tire, and cure it with UV radiation to form a coating film. The performance of the coating film was tested according to the national standard, as shown in Table 1.

Embodiment 2

[0027] 1. Put 12 parts of 200# gasoline solvent in parts by mass, 4 parts of cyclohexane, and 3 parts of butadiene rubber in a closed stirrer, stir for 2 hours at 70°C until completely dissolved, and cool to room temperature .

[0028] 2. Transfer the above solution to a dispersing mixer, add 18 parts of butyl methacrylate, 2 parts of styrene resin, and 0.12 parts of polyether-modified polydimethylsiloxane, and stir for 45 minutes.

[0029] 3. Add 8 parts of color paste, 0.1 part of a mixture of 52% polyacrylate and 48% alkylbenzene, and 1 part of α-aminoalkylphenone photoinitiator into the above-mentioned dispersing mixer, stir for 30 minutes, and discharge Instantly.

[0030] 4. Brush the above ink on the side of the clean tire, and cure it with UV radiation to form a coating film. The performance of the coating film was tested according to the national standard, as shown in Table 1.

Embodiment 3

[0032] 1. Put 10 parts by mass of ethyl acetate and 1 part of natural rubber in a closed stirrer, stir for 1.5 hours at 60°C until completely dissolved, and cool to room temperature.

[0033] 2. Transfer the above solution to a dispersing mixer, add 5 parts of isodecyl acrylate, 6 parts of cyclohexyl methacrylate, 2 parts of acrylic resin, 0.05 part of polyether-modified polydimethylsiloxane, Stir for 10 minutes.

[0034] 3. Add 6 parts of color paste, 0.08 part of a mixture of 52% polyacrylate and 48% alkylbenzene, and 0.5 part of α-aminoalkylphenone photoinitiator into the above-mentioned dispersing mixer, stir for 15 minutes, and discharge Instantly.

[0035] 4. Brush the above ink on the side of the clean tire, and cure it with UV radiation to form a coating film. The performance of the coating film was tested according to the national standard, as shown in Table 1.

Abstract

The invention relates to a colored paint / ink cured on a tyre by using ultraviolet light and a preparation method thereof. The colored paint / ink comprises the following components in parts by weight: 8-18 parts of acrylics, 0.8-2 parts of resin, 8-16 parts of solvent, 0.5-3 parts of rubber, 0.01-0.12 part of dispersing agent, 4-8 parts of color paste, 0.03-0.1 part of flatting agent and 0.15-1 part of photoinitiator. The preparation method comprises the steps of stirring the solvent and rubber in a closed mixing stirrer until the rubber is completely dissolved into transparent liquid; transferring the transparent liquid into a dispersing stirrer; adding the acrylics, the resin and the dispersing agent and stirring; and adding the color paste, the flatting agent and the photoinitiator according to the component ratio, stirring and discharging. According to the colored paint / ink provided by the invention, UV (ultraviolet) irradiates the tyre, so that one-time curing formation is realized, and a film forming object has excellent performance on the tyre of the automobile; and meanwhile, the preparation method has the characteristics of simple process operation and high output.

Description

technical field [0001] The invention relates to the chemical technology field of paint / ink manufacturing, in particular to a color paint / ink that can be cured on tires by ultraviolet light and a preparation method. Background technique [0002] With the advancement of science and technology and the rapid development of industry, higher and stricter requirements are constantly put forward for the performance of coatings / inks and environmental protection. Ultraviolet (UV) photocurable coatings / inks are more and more widely used due to their low production cost, fast reaction speed, low VOC, excellent coating performance after curing, and energy saving. [0003] However, the current UV photocurable color coatings / inks on the market generally have low curing efficiency due to technical reasons, and even non-curing phenomenon on the substrate, and poor storage stability. Therefore, color coatings / inks of other heat-curing systems are generally used in conjunction with colorless ...
