Embodiment Construction

[0013] A water-resistant leather cup material, made of the following raw materials with a weight of kg:

[0014] Nitrile rubber 90, epoxy linseed oil 4, filler 40, zinc stearate 8, aluminum nitride 1, white ointment 2, antioxidant 168 0.6, antioxidant RD 0.5, dimethyl sebacate 2.3, Bamboo charcoal powder 1, quick press carbon black N550 3,

[0015] The packing is made of raw materials with the following weight kg:

[0016] Clay 36, crosslinking agent TAC 1.7, tungsten trioxide 1, diatomaceous earth 18, tributyl citrate 3, silane coupling agent DL602 1, copper oxide 1, polypropylene glycol diglycidyl ether 2, tricresyl phosphate 2 , aluminum hydroxide 9;

[0017] The preparation method of the filler is to calcinate clay and diatomaceous earth at 750°C for 2 hours, take them out, add an appropriate amount of water together with diatomite to grind, add 13% hydrochloric acid solution to adjust the pH to 4.6, and grind the slurry to 700 After the mesh, add sodium hydroxide to ma...

Abstract

The invention discloses a water resistant leather cup material, which is composed of the following raw materials in parts by weight: 90 to 95 parts of butyronitrile rubber, 2 to 4 parts of epoxy linseed oil, 30 to 40 parts of filling material, 8 to 12 parts of zinc stearate, 1 to 2 parts of aluminum nitride, 1 to 2 parts of white factice, 0.3 to 0.6 part of antioxidant 168, 0.1 to 0.5 part of anti-aging agent RD, 2 to 3 parts of dimethyl decanedioate, 1 to 2 parts of bamboo charcoal powder, and 1 to 3 parts of fast extruding carbon black N550. The material has a high environmental fire resistant and water resistant performance and a long service life, can be used under severe and damp circumstance, and maintains excellent and stable properties at the same time.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a water-resistant leather cup material. Background technique [0002] Leather cups are mainly used in automotive hydraulic brake systems, clutch control systems, and afterburner systems to transmit pressure and seal. Existing leather cups are single in variety and performance, and cannot meet the increasing diversified demands. Contents of the invention [0003] The purpose of the invention is to improve a water-resistant cup material. [0004] The above purpose is achieved through the following schemes: [0005] A water-resistant leather bowl material is characterized in that: it is made of the following raw materials in parts by weight: [0006] Nitrile rubber 90-95, epoxy linseed oil 2-4, filler 30-40, zinc stearate 8-12, aluminum nitride 1-2, white ointment 1-2, antioxidant 168 0.3-0.6 , anti-aging agent RD 0.1-0.5, dimethyl sebacate 2-3, bamboo charcoal powder 1-2, quick extruded...
