Problems solved by technology

[0002] At present, in the manufacture of outer tubes for mines, NBR is usually used as the material for the outer tubes. However, due to the harsh environment of the mines, the temperature is too low and the outer tubes are easily damaged, and they are impacted during use. Depression is easy to appear, affecting the use of the outer tube

Abstract

The invention provides a high-stiffness nitrile rubber outer tube rubber formula for mine use. The formula comprises the raw materials in parts by mass: 90-125 parts of nitrile rubber, 70-95 parts of N550 carbon black, 10-30 parts of white carbon black, 20-45 parts of ground calcium carbonate, 2-7 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 5-15 parts of dioctyl adipate, 2-10 parts of resorcinol, 4-7 parts of a shaping agent and 4-7 parts of a hardening agent. By combining high Mooney Nandi raw rubber, Taiwan, China, white carbon black and resorcinol in use, the bonding property of a sizing material and weaving cotton cloth is improved. By using a low-temperature-resistant plasticizer DOA, the low-temperature resistance of a product is improved, a rubber compound is ultrahigh in Mooney, and the rubber tube which is formed is good in stiffness and does no collapse and deform.

Description

technical field [0001] The invention relates to the field of rubber manufacturing, in particular to a formula of high stiffness nitrile rubber outer tube rubber for mines. Background technique [0002] At present, in the manufacture of outer tubes for mines, NBR is usually used as the material for the outer tubes. However, due to the harsh environment of the mines, the temperature is too low and the outer tubes are easily damaged, and they are impacted during use. Depression is easy to appear, which affects the use of the outer tube. Therefore, it is particularly important to solve the problems of poor cold resistance and insufficient stiffness of the nitrile rubber outer tube rubber used in mines. Contents of the invention [0003] For the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a kind of formula of high stiffness mine nitrile rubber outer pipe glue, through nitrile rubber, N550 carbon black, white carbon bla...
