In the field of industrial equipment and consumer products, the wear resistance of printed LOGO on silicone rubber sheet is the key to long-term clarity of brand logo. To achieve this goal, optimization is required from three dimensions: printing process, material selection and surface treatment technology.
1. Printing process selection
Screen printing: Use high-mesh screen (recommended 300 mesh or above) with addition-type silicone ink to ensure ink permeability and adhesion; Pad printing technology: Suitable for curved or concave and convex surfaces, accurately transfer patterns through silicone heads; Laser marking: Permanent logo is formed through non-contact engraving, suitable for high wear-resistant scenes (such as automotive parts).
2. Ink and coating technology
Select two-component addition-cured silicone ink (compliant with FDA/ROHS standards), whose molecular chain is chemically bonded to the substrate, and the wear resistance is 3-5 times higher than that of ordinary ink. For extreme environments, UV-cured protective coating or nano-ceramic coating can be added to reduce the friction coefficient.
3. Surface pretreatment
Before printing, perform plasma treatment or primer spraying on the silicone rubber sheet to increase the surface energy to more than 40mN/m, so that the ink adhesion reaches ASTM D3359 standard B level (no shedding).
4. Wear resistance test
It is recommended to perform Taber wear test (CS-10 wheel, 1kg load, 1000 cycles) according to ASTM D4060 standard to ensure that the LOGO wear rate is less than 5%.
Maintenance suggestions: Avoid using strong acid and alkaline cleaners, and regularly check high-frequency friction areas.
Through the above technical combination, the silicone rubber sheet LOGO can be clearly retained for more than 5 years, meeting the long-term use needs of industrial, medical and outdoor equipment.
