Problems solved by technology
In the past, metal springs were used for shock absorption, and the cushioning effect was poor. Later, pure rubber columnar shock absorbers (without metal sleeves) were used for assembly, which were not easy to fix, and were easy to shift when driving. Poor heat resistance, easy to break, low life, etc., prematurely lose shock absorption performance

Embodiment 1
[0025] Embodiment 1. A special shock-absorbing rubber sleeve for rubber motorcycles, including the following components by weight:
[0043] Example 3. A method for preparing a special shock-absorbing rubber sleeve for rubber motorcycles, using the rubber sleeve group distribution ratio of Example 1, and preparing according to the following steps:
[0044] The first step of rubber preparation process
[0045] (1) Mixing: Put the styrene butadiene rubber into the internal mixer, press for 1 minute and then add zinc oxide, stearic acid, antioxidants, carbon black, and operating aids, press and mix, and the temperature will rise to Debinding at 130℃;
[0046] (2) Open mill: add vulcanizing agent and accelerator on the open mill; the internal mixer dischargemachine puts the rubber into the open mill, the roll temperature is below 55℃, the roll distance is 4mm, after adding sulfur and accelerator, pour rubber from left to right 4 The roller pitch is adjusted to 5mm, and the next film is cooled by water for use;
[0047] The second step rubber blank production process

Abstract
The invention belongs to the technical field of rubber products, mainly relates to a shock-absorption and buffering rubber jacket with rubber and metal heat vulcanization adhesiveness and a preparation method of the shock-absorption and buffering rubber jacket and discloses a special shock-absorption and buffering rubber jacket for a motorcycle. The rubber jacket is prepared from components in parts by weight as follows: 100 parts of styrene-butadiene rubber, 60-70 parts of carbon black, 1.5-2.5 parts of a processing aid, 6.5 parts of an anti-aging agent, 3.1-3.7 parts of an accelerant, 0.5-0.6 parts of sulfur, 4-5 parts of zincoxide and 1.5 parts of stearic acid, wherein the processing aid is prepared from 1.0-1.5 parts of AT-B and 0.5-1.0 part of TM-80, the anti-aging agent is preparedfrom 2.5 parts of 4010, 2.0 parts of 4020 and 2.0 parts of RD, and the accelerant is prepared from 0.7-0.9 parts of TMTD (tetramethyl thiuram disulfide), 0.6-0.8 parts of TETD (tetraethylthiuram disulfide), 0.5-0.6 parts of DTDM and 1.3-1.4 parts of CZ. In order to solve problems in the prior art and improve the heat vulcanization adhesiveness of the special shock-absorption and buffering rubber jacket for the motorcycle, the special shock-absorption and buffering rubber jacket which is ozone-resistant, weather-resistant and good in warping strength for the motorcycle is provided.
Description
Technical field [0001] The invention belongs to the technical field of rubber products, and mainly relates to a shock-absorbing buffer rubber sleeve for thermally vulcanized adhesion of rubber and metal and a preparation method thereof. technical background [0002] The special shock-absorbing rubber sleeve for rubber motorcycles is a shock-absorbing component used in motorcycles. It plays a shock-absorbing and buffering effect, makes the motorcycle run smoothly and comfortably, prevents bumps, protects other parts of the motorcycle, and prolongs its service life. In the past, metal springs were used to absorb the shock, and the cushioning effect was poor. The pure rubber cylindrical shock absorber (without metal casing) was not easy to fix when assembled, and it was easy to move when driving. Due to poor support, it was prone to large deformation, ozone resistance, weather resistance and Poor heat resistance, easy to break, low life and other premature loss of shock absorption p...
