Abstract

The invention provides a sizing material for a spiral spring supporting seat, a preparation method of the sizing material and an automobile spiral spring supporting seat, and the sizing material for the spiral spring supporting seat is prepared from the following components in parts by weight: 60-80 parts of star branched butyl rubber, 20-40 parts of cis-1, 4-polybutadiene rubber, 3-5 parts of zinc oxide, 1-2 parts of stearic acid, 3-6 parts of Sumilink100 and 5-15 parts of thermal isoprene rubber. The composition is prepared from the following components in parts by weight: 20 to 30 parts of carbon black N330, 10 to 15 parts of white carbon black 7000 GR, 1 to 1.5 parts of POLYVEST, 10 to 20 parts of paraffin oil, 5 to 8 parts of an anti-aging agent, 0.75 to 0.85 part of sulfur and 3.70 to 4.35 parts of an accelerant. The rubber material for the spiral spring supporting seat has the characteristics of high damping, high durability, high wear resistance, weather resistance, low temperature resistance and the like, so that the comprehensive performance of the spiral spring supporting seat can be improved.

Description

technical field [0001] The invention relates to the technical field of preparation of helical spring supports, in particular to a rubber material for helical spring support seats. At the same time, the present invention also relates to a preparation method of the above rubber material for the coil spring support seat, and a coil spring support base prepared by using the above rubber material for the coil spring support seat. Background technique [0002] The car coil spring support seat is installed between the frame and the suspension. It is generally made of rubber, and it can reduce the direct impact of the axle on the frame (or body), play a role in buffering and shock absorption, and can limit the suspension. The maximum deformation of the frame can prevent excessive deformation of the automobile shock absorption system and increase the comfort of the driver. [0003] Based on the functional design of the automotive coil spring support seat, the rubber material for the...
