Embodiment 1

[0011] The sealing rubber ring of the brake shoe automatic riveting equipment includes: 15-20 parts of epoxy resin, 5-10 parts of dry oil alkyd resin, 6-12 parts of phenolic resin, polybenzimidazole 1~3 parts, 20~30 parts of graphite powder, 4~8 parts of epoxy-polyamide, 6~18 parts of manganese dioxide, 20~40 parts of butadiene rubber, 3~5 parts of zinc stearate and silicon nitride 2~8 servings.

Embodiment 2

[0013] 20 parts of epoxy resin, 10 parts of dry oil alkyd resin, 12 parts of phenolic resin, 3 parts of polybenzimidazole, 30 parts of graphite powder, 8 parts of epoxy-polyamide, 18 parts of manganese dioxide, cis-butyl 40 parts of rubber, 5 parts of zinc stearate and 8 parts of silicon nitride.

Embodiment 3

[0015] 18 parts of epoxy resin, 7 parts of dry oil alkyd resin, 10 parts of phenolic resin, 2 parts of polybenzimidazole, 25 parts of graphite powder, 6 parts of epoxy-polyamide, 12 parts of manganese dioxide, butadiene 30 parts of rubber, 4 parts of zinc stearate and 5 parts of silicon nitride.

[0016] The advantage of the sealing rubber ring of the brake shoe automatic riveting equipment provided by the present invention is: the formula ratio provided by the present invention, by mixing epoxy resin, dry oil alkyd resin, phenolic resin, polybenzimidazole, graphite powder , Epoxy-polyamide, manganese dioxide, cis-butadiene rubber, zinc stearate and silicon nitride are produced according to the ratio of the sealing rubber ring of the brake shoe automatic riveting equipment, which not only has good wear resistance, but also has good wear resistance. The aging efficiency is obvious, it can be used for a long time under high temperature, and its service life can be greatly extend...

Abstract

The invention relates to a sealing rubber ring for a brake shoe automatic riveting device. The sealing rubber ring is prepared from the following components in parts by weight: 15 to 20 parts of epoxy resin, 5 to 10 parts of dry oil alkyd resin, 6 to 12 parts of phenolic resin, 1 to 3 parts of polybenzimidazole, 20 to 30 parts of graphite powder, 4 to 8 parts of epoxy-polyamide, 6 to 18 parts of manganese dioxide, 20 to 40 parts of butadiene rubber, 3 to 5 parts of zinc stearate and 2 to 8 parts of silicon nitride. Being prepared from the epoxy resin, the dry oil alkyd resin, the phenolic resin, the polybenzimidazole, the graphite powder, the epoxy-polyamide, the manganese dioxide, the butadiene rubber, the zinc stearate and the silicon nitride according to the provided formula proportion, the sealing rubber ring for the brake shoe automatic riveting device not only has good wear resistance, but also is remarkable in anti-aging efficiency, can be used at high temperature for a long time, and has greatly prolonged service life.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a sealing rubber ring of automatic riveting equipment for brake shoes. Background technique [0002] The sealing rubber ring of the brake shoe automatic riveting equipment is suitable for sealing. However, in the prior art, the rubber sealing ring is easily affected by the heat of the equipment itself during use, resulting in aging, which greatly reduces the sealing ring. service life.
