Problems solved by technology

[0003] As we all know, rubber shock-absorbing products, especially bracket-type shock absorbers, buffer blocks, etc., are under greater pressure. As a result, the effects of vibration isolation and shock absorption cannot be achieved. Therefore, how to reduce the creep of shock-absorbing rubber to reduce the amount of rubber compression in a compressed state, so as to obtain good support capacity and shock-absorbing effect, has been expected in this field.

Embodiment 1

[0025] The formula for the shock-absorbing rubber with a hardness of 55HA is as follows:

[0026] .

[0027] Adopt the existing method to make shock-absorbing rubber finished products, the specific process is as follows:

[0028] 1. Weighing: Weigh each raw material according to the above ratio;

[0029] 2. Mixing: first add natural rubber to the open mixer for 5-10 minutes, and then feed in the following order: natural rubber--activator--anti-aging agent--accelerator--carbon black--sulfur;

[0030] 3. The next piece: after all the materials are fully mixed, the next piece is formed, and the thickness is about 5-8mm;

[0031] 4. Vulcanization: The formed semi-finished product is vulcanized by a flat vulcanizing machine, the vulcanization temperature is 160°C, and the time is 30 minutes.

[0032] In the present invention, zinc oxide belongs to active agent, and protective wax belongs to antiaging agent.

[0033] There is no special requirement for the order of adding raw ...

Embodiment 2

[0045] The formula of shock-absorbing rubber with a hardness of 70HA is as follows:

[0046] .

[0047] Adopt the same process condition as embodiment 1 to make shock-absorbing rubber finished product.

[0048] Creep test

[0049] The comparison sample is the WIF0C0RE023 product produced and sold by Wuxi Fuerkang Technology Co., Ltd. (hardness 70HA, the existing product is made of natural rubber and auxiliary materials under the same process conditions, but the selected auxiliary materials are different from the above shock-absorbing rubber auxiliary materials) .

[0050] experiment procedure:

[0051] 1. Preload to 0.5% of the rated load, stop for 3 seconds, and reset the force and displacement;

[0052] 2. Load to 3KN at a speed of 5mm / min, and record the displacement at this time;

[0053] 3. Keep the load constant, and record the deformation corresponding to the compression time of 24 hours for 13 days.

[0054] The result is as follows:

[0055]

[0056] Where...

Embodiment 3

[0059] The formulation of shock-absorbing rubber is as follows:

[0060] .

[0061] Record the above shock-absorbing rubber as 2# (hardness 48HA). The W2FT6050001 product produced and sold by Wuxi Fuerkang Technology Co., Ltd. (recorded as 1#, its hardness is 58HA, this existing product is produced by natural rubber and auxiliary materials using the same process conditions, but the selected auxiliary materials are the same as the above shock absorption Rubber accessories are different) for comparison.

[0062] static test

[0063] Test temperature: 22±2℃

[0064] Loading and unloading speed: 10mm / min

[0065] Maximum load: 1.3 times the rated load

[0066] Entrance force: 0.005 times rated load

[0067] experiment procedure:

[0068] 1. The first load: preload at a speed of 10mm / min to 1.3 times the rated torque, and then unload. Hold for 15s.

[0069] 2. The second load: compress to 1.3 times the rated torque at a speed of 10mm / min, and unload. Record loading and ...

Abstract

The invention discloses a shock-absorbing rubber. The mass ratio of raw materials for the shock-absorbing rubber is as follows: 100 parts of natural rubber; 2-5 parts of active agent ZEH-DL; 5 parts of zinc oxide; 30-80 parts of carbon black; 2 parts of 4010NA; 1.5 parts of anti-aging agent 4020; 1 part of protective wax; 0.5-1 part of sulfur; 1-1.5 parts of accelerator MBS; 0.5-1 part of accelerator TBTD; Compared with the existing shock-absorbing rubber, the shock-absorbing rubber of the present invention has significantly reduced dynamic stiffness, smaller dynamic-to-static ratio, lower creep, and good supporting capacity and shock-absorbing performance.

Description

technical field [0001] The invention belongs to the field of rubber, in particular to a rubber used to manufacture shock absorbing products. Background technique [0002] Shock-absorbing rubber products are used to eliminate or reduce the transmission of mechanical vibration, to achieve shock absorption, noise reduction and reduce the damage caused by impact. These include rubber shock absorbers, rubber buffers (blocks, pads), rubber connectors, air springs and rubber guards, etc. It is pure rubber or rubber products reinforced with fabric and metal skeleton, and is generally manufactured by molding. Widely used in housing construction, mechanical equipment, vehicles, ships and instruments and other industries. [0003] As we all know, rubber shock-absorbing products, especially bracket-type shock absorbers, buffer blocks, etc., are under greater pressure. As a result, the effect of vibration isolation and shock absorption cannot be achieved. Therefore, how to reduce the ...
