Abstract

The invention relates to self-lubricating insulating rubber for a vehicle auxiliary frame limiting block and a processing technology of the self-lubricating insulating rubber. The rubber comprises the following raw materials in parts by weight: 60-80 parts of natural rubber, 5-10 parts of eucommia ulmoides rubber, 5-10 parts of thermoplastic vulcanized rubber TPV, 10-20 parts of fast extruding furnace black, 20-30 parts of semi-reinforcing carbon black, 10-20 parts of white carbon black, 5-15 parts of paraffin oil, 5-8 parts of zinc oxide, 1-2 parts of stearic acid, 3-5 parts of paraffin, 2-3 parts of a silane coupling agent, 3-5 parts of an anti-aging agent, 4-8 parts of polytetrafluoroethylene, 2-3 parts of a lubricant, 2-3 parts of sulfur and 1-2 parts of an accelerant. A layer of uniform enveloping film with low friction coefficient is arranged between the rubber and the metal piece, the friction force between the rubber and the metal piece is small, and the abrasion of the rubber and the friction noise between the rubber and the metal piece are reduced.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a self-lubricating insulating rubber for a limit block of a sub-frame of a vehicle and a processing technology thereof. Background technique [0002] The limit block of the subframe is an important accessory to ensure the stability and driving comfort of the vehicle body. It directly bears the total downward weight of the car and the rebound force of the ground, buffers the impact caused by uneven roads on the body, attenuates the vibration of the car during driving, and maintains driving comfort. It is combined with the sub-frame bushing to ensure car driving stability. With its superior resilience and flex resistance, rubber is widely used in the connection parts of the chassis system and body for cushioning and shock absorption. Natural rubber products such as sub-frame limit blocks are commonly used at the junction of the chassis. Since there will be up and down collisions...
