Hot bending protection ink and hot bending polishing process of glass cover plate

Abstract

The invention relates to hot-bending protective ink and a hot-bending polishing process of a glass cover plate. The protective ink is prepared from the following components in percentage by weight: 45-55% of silicon resin, 5-15% of aluminum oxide, 15-25% of auxiliaries, 5-15% of calcium carbonate and 5-15% of glass powder. According to the hot bending polishing process, hot bending protection printing ink is adopted, so the effect of an interlayer can be effectively achieved, the proportion of concave-convex points is reduced, mold damage is reduced, the service life of a mold is prolonged, the polishing capacity is improved, the proportion of poor polishing is reduced, and cost is saved.

Description

technical field

[0001] The invention relates to the technical field of glass cover processing, in particular to a thermal bending protection ink and a thermal bending polishing process for a glass cover. Background technique

[0002] Affected by the complex structure of the curved surface of 3D products, the current industry has stricter requirements on the glass cover plate. The original appearance of the product has a high proportion of concave and convex points. Due to improper cleaning of graphite dust, it is easy to scratch the mold, resulting in poor appearance of product concave and convex points and dents. For hot bending The resulting defects and the increase in polishing time will increase the cost of the enterprise. It takes a long time to improve the appearance of the glass cover and polish to remove the bumps and indentations, which directly increases the cost of hot bending and polishing. Therefore, the protection during the processing of the glass cover is ver...
