Abstract

The invention relates to the technical field of ink, in particular to an acid-and-alkali-resistant environment-friendly ink for an automotive windscreen.The acid-and-alkali-resistant environment-friendly ink is characterized by being prepared from, by mass, 50%-70% of lead-and-cadmium-free composite glass powder, 8%-20% of inorganic pigment, 20%-40% of varnish, 0.6%-1% of dispersing agent, 0.6%-1% of flatting agent and 0.3%-0.6% of thixotropic agent.The acid-and-alkali-resistant environment-friendly ink for the automotive windscreen is efficient and environmentally friendly, has excellent acid and alkali resistance and suitable sintering temperature, is good in water resistance, high in adhesive force and good in ultraviolet resistance, and has the quite low light transmissivity, and foreign-automobile-windscreen ink products can be replaced with the ink.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an acid and alkali-resistant environmental protection ink for automobile windshields and a preparation method thereof. Background technique [0002] Automobile windshield ink is coated on the surface of the automobile windshield and subjected to high-temperature bending treatment at 600-700°C, which can absorb ultraviolet rays, effectively reduce the transmittance of ultraviolet rays, and prevent the occurrence of glue used to bond glass and car body Chemical changes, shielding conductive silver paste and playing the role of decorating the appearance of the car body. With the rapid development of the automobile industry and the increasing requirements of people's environmental living standards, the environmental protection, chemical corrosion resistance and Anti-bonding and other properties are getting more and more attention. [0003] Among the existing automobile windshield inks ...
