Embodiment 1

[0019] The high-stability UV-curable water-based ink for glass is prepared from the following raw materials in parts by weight: acrylate-modified polysiloxane prepolymer: 55 parts; pigment: 1 part; benzoin methyl ether : 5 parts; pentaerythritol triacrylate: 15 parts; tributyl phosphate: 3 parts; propanol and water mixed solvent: 100 parts.

[0020] The acrylate-modified polysiloxane prepolymer is prepared by the following steps: mixing two-terminated hydroxyl dimethylpolysiloxane and γ-methacryloxypropyltrimethoxysilane and stirring, Then add dibutyltin dilaurate, heat to 80°C for 8 hours, and obtain it after purification.

[0021] Mix acrylate-modified polysiloxane prepolymer, pigment, pentaerythritol triacrylate, tributyl phosphate, propanol and water as a solvent, fully mix and heat to 30°C and stir for 10 minutes, then add benzoin methyl ether and stir evenly , and then leave it to cool to obtain a high-stability UV-curable water-based ink for glass.

Embodiment 2

[0023] The high-stability UV-curable water-based ink for glass is prepared from the following raw materials in parts by weight: acrylate-modified polysiloxane prepolymer: 60 parts; pigment: 2 parts; benzoin ether: 4 parts; polydipentaerythritol pentaacrylate: 18 parts; tributyl phosphate: 5 parts; propanol and water mixed solvent: 120 parts.

[0024] The acrylate-modified polysiloxane prepolymer is prepared by the following steps: mixing two-terminated hydroxyl dimethylpolysiloxane and γ-methacryloxypropyltrimethoxysilane and stirring, Then add dibutyltin dilaurate, heat to 100°C for 10h, and obtain it after purification.

[0025] Mix the acrylate-modified polysiloxane prepolymer, pigment, polydipentaerythritol pentaacrylate, tributyl phosphate, propanol and water as a solvent, fully mix and heat to 50°C and stir for 30 minutes, then add benzoin ether, stir Uniform, and then let it stand for cooling to get a high-stability UV-curable water-based ink for glass.

Abstract

The invention relates to the technical field of coatings, in particular to high-stability UV (Ultraviolet) light curable water-based ink for glass. The high-stability UV light curable water-based ink for the glass is prepared by the following raw materials in part by weight: 50-60 parts of acrylate modified polysiloxane prepolymer, 1-2 parts of pigment, 2-5 parts of a photopolymerization initiator, 10-20 parts of an active diluent, 1-5 parts of an antifoaming agent and 100-120 parts of an aqueous solvent. The high-stability UV light curable water-based ink has the advantages that the storage stability, the curing rate, the flexibility and the hardness are good, energy sources are saved, the environmental protection is facilitated, the process is simplified, the product quality is improved, and the development prospect is wide.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-stability ultraviolet light-curable water-based ink for glass. Background technique [0002] In recent years, with people's increasing emphasis on environmental protection and the gradual strengthening of environmental protection regulations, countries have increasingly restricted the emission of volatile organic compounds contained in traditional solvent-based coatings. Therefore, the development of low-pollution or even non-pollution environment-friendly water-based coatings and light-cured coatings has become the main direction of coating development. [0003] UV-cured water-based coatings combine the advantages of water-based technology and UV-cured technology, and have the advantages of fast curing speed, environmental friendliness and energy saving. The shortcomings such as poor coating performance brought by the technology are unmatched by many traditional coating...
