Embodiment 1

[0030] Choose NR for non-crystalline rubber and TPI for crystalline rubber. The basic formula is:

[0031] 80 parts of NR; 20 parts of TPI; 55 parts of carbon black CB;

[0032] 5 parts of zinc oxide; 2 parts of stearic acid; 3 parts of sulfur and accelerator;

[0033] Other complexing agents 25.

[0034] The equipment used in this embodiment is F270 internal mixer, the rotating speed: 20-40 rpm, the air pressure of the upper bolt: 0.6MPa, and the initial temperature of pre-plasticization is 100°C.

[0035] When the room temperature of the internal mixer reaches the initial temperature of 100°C or above, put in 100kg of TPI glue, press the top bolt, and when the temperature of the mixing chamber of the internal mixer reaches 115°C or above, lift the top bolt, put in 100kg of NR glue, Press the upper bolt and continue mixing until the temperature of the mixing chamber of the internal mixer reaches 145°C to 155°C, discharge the rubber and discharge the sheet to prepare 200kg o...

Embodiment 2

[0040] Choose NR for non-crystalline rubber and TPI for crystalline rubber. The basic formula is:

[0041] 90 parts of NR; 10 parts of TPI; 58 parts of carbon black; 3 parts of coupling agent;

[0042] 3.5 parts of zinc oxide; 2 parts of stearic acid; 1.1 parts of sulfur; 1.7 parts of accelerator;

[0043] Other compounding ingredients: such as 2.5 parts of anti-aging agent; 0.25 parts of anti-scorch agent; 1 part of microcrystalline wax.

[0044] The mixing method of this example is as described in Example 1. The formula of this example is suitable for all-steel heavy-duty tread rubber, and the final rubber is molded, formed, and vulcanized to obtain a finished product. The performance of the rubber compound can basically reach the performance of all-steel heavy-duty tread rubber using NR. The performance comparison data are as follows:

Embodiment 3

[0047] Choose NR for non-crystalline rubber and TPI for crystalline rubber. The basic formula is:

[0048]NR 40 BR 50; TPI 10;

[0049] 58 parts of carbon black; 1 part of coupling agent; 3.5 parts of zinc oxide;

[0050] 2 parts of stearic acid; 1.7 parts of sulfur; 1 part of accelerator;

[0051] Other compounding ingredients: such as 3 parts of anti-aging agent; 1 part of dispersant; 0.15 parts of anti-scorch agent; 1 part of microcrystalline wax.

[0052] The mixing method of this example is as described in Example 1. The formula of this example is suitable for bias load tread rubber, and the final compounded rubber is molded, formed, and vulcanized to obtain a finished product. The performance of the rubber compound can basically reach the performance of the bias load tread rubber using 50 parts of NR and 50 parts of BR. The performance comparison data are as follows:

Abstract

The invention relates to the rubber blending and rubber mixing technology in the rubber tire field and tires prepared from the mixed rubber. The tire compound composition using trans isoprene rubber comprises the following components in weight of: trans isoprene rubber TPI 1-99 parts, natural rubber NR 1-99 parts, and the total weight of rubber in the composition is 100 parts. The invention realizes the blending and dispersing of two or more kinds of trans isoprene rubber TPI and natural rubber NR, reduces production cost; at the same time, the blended composition can achieve high blending anddispersing in macro and micro structure, and can express the excellent performance of the macromolecule composite material furthest.

Description

technical field [0001] The invention relates to the blending of rubbers in the field of rubber tires, a rubber mixing process and tires prepared from the mixed rubbers. technical background [0002] Usually, rubber blending or rubber-plastic blending is to put two or more high polymers into the mixing equipment at the same time or in sequence, and then add various compounding ingredients for mixing. Since Benbury invented the internal mixer, most rubber product factories and tire factories with a certain scale have used internal mixers for rubber or rubber-plastic blending, and the models of internal mixing equipment have covered from 1.5 liters There are many models of small internal mixers for laboratories to large 550-liter internal mixers used in large-scale factory production, such as: WM140 / 20, F270, GK370, F370, GK450 and so on. But no matter which type of internal mixer equipment, the mixing effect of internal mixer is better for a single rubber or two or more rubbe...
