Abstract

The invention relates to a printing ink for side windshield of an automobile and a preparation method of the printing ink. The printing ink is characterized by consisting of the following components in percentage by mass: 6-24 percent of organic resin, 10-28 percent of solvent, 2-12 percent of flatting agent, 2-10 percent of dispersant and the balance of leadless glass powder. The printing ink for the side windshield of the automobile and the preparation method of the printing ink have the beneficial effects that: 1, the printing ink is mainly prepared from the leadless glass powder and can be easily accepted by people; 2, resin containing no harmful substances such as chlorine is added into the printing ink, the wettability and the surface smoothness of the printing ink and the bond strength of the printing ink and glass after sintering are good, the shading rate is high, and the printing ink can be used for completely substituting the conventional printing ink to be used in the field of production of the side windshield of the automobile; and 3, the printing ink contains no harmful substances such as lead, cadmium, mercury, sexavalent chromium, PBB (Polybrominated Biphenyl) and PBDE (Polybrominated Diphenyl Ether). By adjusting the contents of various inorganic components and organic components, the printing ink can adapt to a glass substrate, so that the product performance is more superior.

Description

technical field [0001] The invention relates to an ink for automobile side windshield 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 special printing ink that is applicable to the side windshield of automobile is also seldom reported. [0003] In view of the above existing deficiencies in the ink for the side-shield...
