Problems solved by technology

At present, most of the products used in the market contain lead, cadmium and other ingredients. Under the current environmental protection situation, the pollution caused by the use of lead and cadmium makes the environment take many years to recover.
On the other hand, the glossiness of common automotive glass inks is not high, and mirror inks suitable for automotive glass are rarely reported.
[0003] In view of the above existing deficiencies in the ink for automotive glass, it is imperative to develop a mirror ink for automotive glass that can replace the existing mirror ink for automotive glass that contains lead and has low gloss.

Abstract

The invention relates to mirror ink for automotive glass and a preparation method of the mirror ink. The mirror ink is characterized by comprising, by mass, 10-30% of organic carriers, 2-8% of solvent, 2-8% of pigment raw materials and the balance unleaded glass powder. The ink for the automotive side windshield glass contains no harmful substances such as lead, cadmium, mercury, hexavalent chromium, PBB (polybrominated biphenyl) and PBDE (polybrominated diphenyl ethers) so as to meet the requirements of social devolvement on environmental protection. The mirror ink has the advantages that the mirror ink gives priority to the unleaded glass powder which contains no elements such as lead, cadmium, mercury and hexavalent chromium harmful to the environment, so that environmental protection is benefited; and the mirror ink is good in wettability, surface smoothness and bonding strength with the glass after sintering and high in shading rate and acid-resistant, has gloss exceeding requirements of general manufacturers and can completely substitute for exiting ink to be used for the field of automotive glass manufacturing.

Description

technical field [0001] The invention relates to a mirror ink for automobile glass and a preparation method thereof. Background technique [0002] There are many types of inks that are seen in daily life, and there are mainly three kinds of inks that are suitable for automobile glass: ink for automobile front windshield, ink for automobile side windshield and ink for automobile rear windshield tempered glass, that is, ink used around the window glass The black part mainly plays the role of decoration and UV protection. At present, most of the products used in the market contain lead, cadmium and other ingredients. Under the current environmental protection situation, the pollution caused by the use of lead and cadmium will take many years to restore the environment. On the other hand, the glossiness of common automotive glass inks is not high, and mirror inks suitable for automotive glass are rarely reported.
