Problems solved by technology

However, EPDM is expensive, and the accelerator is very easy to spray out, has poor wear resistance, and poor friction with paper; natural rubber has poor ozone resistance and aging resistance, and the price fluctuates greatly, and there will also be plasticizers and anti-aging agents. Ejection phenomenon, resulting in weakened friction

Embodiment 1～4

[0041] According to the following steps, the special rubber compound for printer paper feeding rubber roller involved in the present invention is produced

[0042] Prepare rubber, according to the ratio in Table 1, weigh the raw materials accurately in the order of styrene-butadiene rubber→reinforcing filler, white carbon black→anti-aging agent, antistatic agent, other compounding agent→softener→vulcanization accelerator, and put it aside spare.

[0043] The first mixing: put styrene-butadiene rubber, anti-aging agent, antistatic agent and other compounding ingredients into the internal mixer for mixing, and the mixing time is 60s; put in the softener first, and then add the reinforcing filler and white carbon Put the black together into the internal mixer, after mixing for 80-100s, clean the upper bolt, and finally mix for 50-70s, unload and discharge the sheet, and make A mixing rubber for later use.

[0044] The second mixing: Put the rubber compound A and the vulcanizatio...

Abstract

The invention discloses a special rubber compound for a paper conveying rubber roll of printing paper. The special rubber compound is prepared from the following components in percentage by weight: 46 percent to 55 percent of butadiene styrene rubber, 15 percent to 20 percent of white carbon black, 15 percent to 20 percent of reinforcing fillers, 4 percent to 9 percent of a softening agent, 2 percent to 5 percent of other compounding ingredients, 2 percent to 5 percent of an anti-ageing agent, 1.5 percent to 2.3 percent of a vulcanizing accelerator and 2 percent to 5 percent of an antistatic agent. The special rubber compound disclosed by the invention has the advantages of good ozone-resisting performance, small rigidity changes, high tensile strength, easiness of machining, good wearing resistance, antistatic property and stability, excellent comprehensive performances and low cost, and can meet the use requirements of current paper conveying rubber rolls of a printer.

Description

technical field [0001] The invention relates to a rubber, in particular to a special compounded rubber for a printer paper feeding rubber roller and a preparation method thereof. Background technique [0002] With the continuous development of the modern social economy, the scope of rubber use continues to expand, and the types are becoming more and more complicated and diversified. It has become an indispensable and important accessory in the development of modern industry and social life. The development of the rubber roller industry puts forward higher requirements on the performance of the rubber used. [0003] The working environment of the paper feeding roller of the printer is relatively special. In addition to the necessary friction, good wear resistance and antistatic property, the rubber roller should also have good physical properties, heat aging resistance and ozone resistance. . [0004] Previously commonly used printer feeding formulas used EPDM or natural ru...
