Problems solved by technology

[0004] Since the supporting part of the tire is the main stress-bearing part when the air pressure of the tire is reduced, the heat generation of the part increases. At the same time, due to the obvious increase in the thickness of the part, the thermal effect and fatigue damage will aggravate the damage of the tire

Embodiment 1

[0041] The invention provides a kind of rubber mixing method, comprises the following steps:

[0042] (1) Mastication: Weigh natural rubber and environment-friendly peptizer and place them in an open mill for plastication to obtain natural plasticized rubber.

[0043] (2) One-stage mixing: put natural plastic rubber and rare earth butadiene rubber into the internal mixer, and under the condition of the speed of internal mixer at 50rpm, mix the rubber to 140°C and lift the top bolt floating weight for 90s, and then put it into Mo The stone fiber, white carbon black, silane coupling agent and 2 / 3 of the carbon black are in the internal mixer, under the condition of the internal mixer speed of 60rpm, and under the condition of 150°C, lift the top bolt to float After 80 seconds, adjust the speed of the internal mixer to 60rpm and lower it to 130°C for mixing. After the mixed material is unloaded, pressed into tablets and cooled, it is crushed and sieved to obtain a section of mixe...

Embodiment 2

[0055] A kind of rubber mixing method, rubber compound and application provided in this embodiment are roughly the same as in Example 1, the main difference being:

[0056] Including the following raw materials by weight: 60 parts of natural rubber, 2 parts of environmental peptizer, 40 parts of rare earth butadiene rubber containing nearly 98% cis-1,4 structure content, 22 parts of white carbon black, silane coupling agent 2.4 parts, 35 parts of carbon black, 7 parts of active agent, 2 parts of microcrystalline wax, 2 parts of anti-aging agent 6PPD, 2 parts of anti-aging agent TMQ, 1 part of microcrystalline paraffin, 2 parts of insoluble sulfur, 3 parts of mullite fiber, aromatic 4 parts of fiber staple, 1.8 parts of accelerator TBBS, 1 part of accelerator DPG, 0.1 part of anti-scorch agent CTP;

[0057] The silane coupling agent is vinyltrimethoxysilane;

[0058] In step (2), put the natural plasticized rubber and rare earth butadiene rubber into the internal mixer, and un...

Embodiment 3

[0065] A kind of rubber mixing method, rubber compound and application provided in this embodiment are roughly the same as in Example 1, the main difference being:

[0066] Including the following raw materials in parts by weight: 80 parts of natural rubber, 3 parts of environmentally friendly peptizer, 60 parts of rare earth butadiene rubber containing nearly 98% cis-1,4 structure content, 30 parts of white carbon black, silane coupling agent 3 parts, 40 parts of carbon black, 10 parts of active agent, 2 parts of microcrystalline wax, 2 parts of anti-aging agent 6PPD, 2 parts of anti-aging agent TMQ, 1.5 parts of microcrystalline paraffin, 2.2 parts of insoluble sulfur, 4 parts of mullite fiber, aromatic 6 parts of fiber staple, 2.2 parts of accelerator TBBS, 1.5 parts of accelerator DPG, 0.2 parts of anti-scorch agent CTP;

[0067] The silane coupling agent is vinyltrisilane;

[0068] In step (2), put the natural plasticized rubber and rare earth butadiene rubber into the i...

Abstract

The invention relates to the technical field of rubber mixing, in particular to a rubber mixing method, mixed rubber and application. According to the invention, the mixing uniformity of the rubber compound is improved, the physical and mechanical properties of the rubber compound are improved, the dynamic properties of the rubber compound can be improved, heat generation and rolling resistance are reduced, the fatigue resistance and crack resistance of the rubber compound are improved, and the service life of a tire is prolonged; the composite material has enough rigidity, and also has enough flex resistance, tear resistance and low heat generation performance.

Description

technical field [0001] The invention relates to the technical field of rubber mixing, in particular to a rubber mixing method, rubber mixing and application. Background technique [0002] With the development of the automobile industry, automobiles have become an indispensable means of transportation in people's lives, which has also promoted the continuous innovation and progress of the tire industry, and put forward higher requirements for the safety performance of tires during driving, especially It is the air pressure of the tire during high-speed driving. Once there is a leak, the tire air pressure will drop, and the car will lose its balance and cannot drive normally and control the direction. In the case of air pressure, it has a certain support force and driving performance is the direction pursued by major tire manufacturers. [0003] The principle of the tire with this kind of anti-bending and strong supporting part is to add enough rigidity to the sidewall of the...
