Piano black printing ink

Abstract

The invention discloses piano black printing ink. The printing ink comprises 5-15g of 00426GP piano black and 0.5-1.5g of 240CATALYST curing agent, wherein the 00426GP piano black and the 240CATALYST curing agent are baked at 70 DEG C for 40 minutes. The printing ink has strong adhesion, is fast to dry, has high gloss and excellent levelling property, does not have cracks, spreading or pinholes on the materials, has full strength and durability and is pollution-free and environment-friendly.

Description

technical field [0001] The invention relates to the field of inks, in particular to a piano black ink. Background technique [0002] With the rapid development of my country's national economy, the prosperity of the printing and packaging industry has led to the rapid growth of the ink manufacturing industry, making my country rapidly rise to become one of the world's largest ink manufacturing countries in the past ten years. At present, the scale of the domestic ink industry is increasing by 10%. The above speed continues to grow rapidly. [0003] The development of the ink industry in recent years has made the industry prosperous, but at the same time, we should also see the shortcomings in the development of the industry. The scale of the enterprise is small, and the market share of a single enterprise is not high; the technological innovation ability is not strong; The environmental protection is not strong; the supply of high-end products is insufficient; the lack of in...

Problems solved by technology

[0006] When the plastic has high resistance to chemical changes, some crystalline plastics cannot combine with the organic solvent in the ink coating, causing the ink coating to not easily adhere to the surface of the plastic shell, increasing the difficulty of painting and coloring and easy to peel off the paint; on the contrary, Due to the low chemical resistance of some amorphous plastics, the plastics will be eroded by organic solvents, which will cause cracks and structural damage on the surface of the plastic shell, resulting in a very high defect rate

[0007] The inks currently on the market have poor adhesion, long drying time, dull inks, and excellent leveling inks, which are prone to cracks, ink diffusion and pinholes on the material, insufficient strength and durability, and easy to pollute the environment. Not enough environmental protection and other issues
