Problems solved by technology

However, in the scheme of the prior art, the granularity of the ink is required to be relatively large, and the ink needs to be strictly filtered with a 420-mesh mesh before it can be used. In addition, the product printing in the ink configuration is likely to cause fine impurities and hard particles. After hot bending, it will cause deep concave and convex points on the product, which makes the ink configuration difficult to operate

Embodiment 1

[0042] A kind of hot bending protection ink of the present invention, the composition of described protection ink comprises: silicone resin 50%, aluminum oxide 10%, accelerator DM20%, calcium carbonate 10% and glass powder 10% according to weight percentage; Glass powder adopts It is made by mixing poly-p-phenylene benzobisoxazole fiber, silicon dioxide and titanium dioxide. Hot bending protection ink is white paste fluid with aromatic smell, molecular weight MN*10 3 21, temperature resistance 800-1000°C, flash point 56°C, Xiang value 4KOHmg / g, acid value 5KOHmg / g.

[0043] The preparation method is as follows: Measure the above-mentioned raw materials, take them separately according to the proportion of raw materials, put all the raw materials except the accelerator DM into the mixer for stirring and mixing, the stirring speed is the stirring speed of the mixing barrel (counterclockwise): 60±2r / min, rotating speed of stirring blade (clockwise): 80±5r / min, working gap betwee...

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...
