Problems solved by technology

Among them, the surface composite method is not only cumbersome, but also cannot give full play to the inherent characteristics of rubber materials; rubber products with surface coating and surface treatment are easy to wear and have poor durability when used in dynamic seals; Therefore, in recent years, great attention has been paid to the use of solid lubricants, especially solid lubricants solidified in the rubber to reduce the friction factor of rubber sealing products

Embodiment

[0029] The production of EPDM for environmental protection self-lubricating wire harness sheaths in Examples 1 to 6 was carried out according to the composition ratio in Table 1.

[0030] Manufacture the EPDM for the environmental protection self-lubricating wire harness sheath of the present invention according to the following steps:

[0031] (1) Raw material preparation: According to the ingredients and proportions in Table 1, weigh EPDM rubber, carbon black, softening plasticizer, active agent and self-lubricating aid respectively and mix them to form ingredient A, and weigh the vulcanizing agent Reform ingredient B;

[0032] (2) The first mixing: Put ingredient A into the internal mixer for 60-90 seconds, lift the hammer to clean, then press the hammer to mix for 60-90 seconds, lift the hammer to clean again (temperature 140-150°C), and then press the hammer Mix for 120-180 seconds and unload (temperature 150-170°C) to the feeder to discharge the sheet to make rubber com...

Abstract

The invention discloses environmentally-friendly self-lubricating wiring harness sheath EPDM, which comprises, by weight, 27.2-40.1% of ethylene propylene diene monomer rubber, 38.6-44.0% of carbon black, 12.3-18.8% of a softening plasticizer, 2.1-2.8% of an active agent, 2.9-5.1% of a self-lubricating auxiliary agent, and 2.5-3.3% of a vulcanizing agent. According to the present invention, the environmentally-friendly self-lubricating wiring harness sheath EPDM is an environmentally-friendly wiring harness sheath EPDM rubber material with excellent physical and mechanical properties and extremely low friction coefficient.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to an EPDM for an environment-friendly self-lubricating wire harness sheath and a preparation method thereof. Background technique [0002] Due to the high friction coefficient of rubber materials, lubricants are often applied to rubber products, so lubricant loss and pollution often occur during mechanical operation. To this end, the following methods are used to reduce the friction coefficient of rubber sealing products: 1. Surface modification, including surface compounding, surface coating and surface treatment; 2. Oil matching, oil is sprayed from rubber products; 3. Adding solid lubricant. Among them, the surface composite method is not only cumbersome, but also cannot give full play to the inherent characteristics of rubber materials; rubber products with surface coating and surface treatment are easy to wear and have poor durability when used in dynamic seals; Therefore, ...
