Abstract

The invention relates to the field of design rubber materials, in particular to a stamp rubber material capable of being used for capacitor printing and a preparation method thereof. The stamp rubbermaterial is prepared by, by weight, 50-70 parts of nitrile-butadiene rubber, 30-50 parts of epoxidized natural rubber, 30-50 parts of filler, 10-25 parts of activating agent, 1-5 parts of anti-aging agent, 3-8 parts of accelerant, 2-5 parts of vulcanizing agent and 1-3 parts of pigment.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber stamp material which can be used for printing on capacitors and a preparation method thereof. Background technique [0002] Today's 21st century has entered the electronic age, the output of electronic products has also increased rapidly, and the industry competition has become increasingly fierce. For manufacturers, the headache is that there will be a logo on the surface of each electronic component product, and the logo needs to be stamped on it. On the one hand, the manufacturer maintains production costs, and on the other hand, it must ensure efficiency. The first thing that comes to mind is the inkjet printer, because the inkjet printer has a wide range of uses, but the use of the inkjet printer faces high cost investment, followed by high maintenance costs. Therefore, stamp rubber came into being, which is not only low cost, zero maintenance cost, but also high ef...
