Si-692 parts of coupling agent, 5~10 parts of machine oil；2~3 parts of sulphur, 1.2~1.8 parts of vulcanization accelerator.
The rubber and plastic glue is rubber and plastic 34.70, and the blending of rubber and plastic glue, natural rubber, cis-butadiene cement adds the resistance to of vulcanization rubber
Ageing properties.
The white carbon is Tonghua white carbon, and the carbon black is wet method N330 carbon blacks, and is increased with silane coupling agent si-69
Inorganic filler and the compatibility of rubber macromolecule；White carbon plays the wear-resisting property for increasing vulcanization of rubber glue in reinforcing rubber,
And reduce the cost of rubber compounding, requirement Gao Dingshen in rubber product, also have in the comprehensive performance of high intensity it is certain
Effect.
The dosage of the sulphur be 2.5 parts, the vulcanization accelerator be 1 part of CZ, 0.4 part of TMTD, this formula selection sulphur
Change vulcanizing system, increase crosslinked polymeric elasticity；In rubber compounding select sulfur cross-linking system, vulcanization of rubber glue it is comprehensive
It can preferably, simultaneously because sulfur cross-linking system does not have preferable ageing-resistant stability, so being selected in this formula a variety of anti-old
Agent and with achieving the effect that preferable weathering aging..
A kind of preparation method of anticorrosion antiwear rubber pad, preparation are divided into two steps：A rubber and plastic glue is plasticated, and rubber and plastic glue is in mill
It is logical 5~8 times thin on machine, and natural rubber, butadiene rubber and the rubber and plastic glue plasticated are carried out mixing 2 minutes in mixer,
Wherein the rotating speed of mixer is 60r/min.
B adds in white carbon, carbon black and barium sulfate, clay, machine oil simultaneously mixing 2~3 minutes in mixing, and wherein rotating speed is
90r/min, mixing is as stage casing rubber compound after raw rubber adds in reinforcement；Stage casing rubber compound is adding in various anti-aging agent mixings 1 minute
Back glue becomes two-stage mixing glue.
The two-stage mixing glue adds in sulphur and vulcanization accelerator in mill machine, and the roller temperature of wherein open mill is set to 90~
100 DEG C, and cooling water is passed through, cooling water is open-minded when being set to roller temperature more than 110 DEG C.
Beneficial effects of the present invention are：Vulcanization of rubber glue prepared in accordance with the present invention, comprehensive performance is preferable, wear-resisting property
Meet rubber seal product wear criteria；The processing performance of rubber is preferable, does not stick roller, 160 DEG C of * 300s of standard sample vulcanizate
Depanning, curingprocess rate is very fast, and production efficiency is higher.
