[0030] A kind of preparation method of mine tire tread of the present invention, described mine tire formula is as the formula of above-mentioned a kind of mine tire, and its process steps are as follows:

[0031] 1. Put in emulsion polystyrene butadiene rubber, natural rubber, active agent zinc oxide, anti-aging agent, dispersant FS-97, stearic acid, protective wax, paraffin wax, tackifying resin, aramid pulp short fiber, and mix for 20~ 40 seconds, the oil pressure is 12~15MPa;

[0032] 2. Put in 70-90% carbon black, mix for 50-80 seconds, and the oil pressure is 12-15MPa;

[0033] 3. Put in the remaining carbon black and aromatic oil, mix for 50-100 seconds, the mixing temperature is 155-165°C, the oil pressure is 12-15MPa, and the film is obtained;

[0034] 4. The film is cooled by a water tank with a release agent solution, then cooled by a fan for 2 hours, and naturally cooled for 8 hours;

[0035] 5. Put in cooled film, sulfur, accelerator NS, anti-scorch agent, knead...

Embodiment 1

[0038] Example 1, the percentage weight ratio of raw material components: styrene butadiene emulsion rubber 40%, natural rubber 10%, zinc oxide 2.5%, super wear-resistant carbon black N220 33%, anti-aging agent RD 0.7%, anti-aging agent IPPD 0.8%, stearic acid 0.5%, protective wax 0.5%, paraffin wax 0.5%, tackifying resin rosin 2.5%, aramid pulp short fiber D3500 2.7%, aromatic oil 3.5%, dispersant FS-97 1%, sulfur 0.9 %, accelerator NS 0.8%, anti-scorch agent CTP 0.1%.

[0039] The preparation process is carried out in an internal mixer:

[0040] 1. Put in emulsion polystyrene butadiene rubber, natural rubber, active agent zinc oxide, anti-aging agent, dispersant FS-97, stearic acid, protective wax, paraffin wax, tackifying resin, aramid pulp short fiber, and knead for 20- 40 seconds, the oil pressure is 12~15MPa;

[0041] 2. Put in 70-90% carbon black, mix for 50-80 seconds, and the oil pressure is 12-15MPa;

[0042] 3. Put in the remaining carbon black and aromatic oil, ...

Embodiment 2

[0051] Embodiment 2, a kind of mine tire tread is made up of the raw material of following percentage weight ratio: polystyrene butadiene emulsion 44%, natural rubber 7%, zinc oxide 2%, super wear-resistant carbon black N220 30%, anti-aging Agent RD 1.0%, anti-aging agent IPPD 1.0%, stearic acid 0.5%, protective wax 0.6%, paraffin wax 0.6%, tackifying resin C5 3%, aramid pulp short fiber D3500 3.5%, aromatic oil 3%, dispersant FS-97 1.0%, sulfur 1.2%, accelerator NS 1.5%, anti-scorch agent CTP 0.1%.

Abstract

The invention discloses a mine tire and a preparation method thereof. The invention is characterized in that the mine tire is prepared from the following raw materials in percentage by weight by a Banbury mixer: 35-60% of emulsion-polymerized butadiene-styrene rubber, 0-15% of natural rubber, 1-4% of activator zinc oxide, 25-38% of medium / super-wear-resistance carbon black, 0.2-2.0% of anti-aging agent RD, 0.2-2.0% of anti-aging agent IPPD, 0.3-1.0% of stearic acid, 0.3-1.2% of protective wax, 0.3-1.1% of paraffin, 1-5% of tackifying resin, 1.5-6% of aramid fiber pulp short fiber, 1-5% of aromatic oil, 0.5-1.5% of dispersing agent FS-97, 0.5-2% of sulfur, 0.5-2.5% of accelerator NS and 0.05-0.3% of anti-scorching agent. The tire tread has the advantages of high hardness, high tensile strength and excellent rubber tear resistance, is capable of effectively reducing the phenomenon of loosening of tread plug and enhancing the service performance and traveling safety of the mine tire, and prolongs the service life of the tire.

Description

[0001] Technical field: [0002] The invention relates to the technical field of tires, in particular to a raw material composition of a mine tire tread and a preparation method thereof. [0003] Background technique: [0004] As we all know, the conditions of the mining area are extremely harsh. The road surface is covered with sharp gravel, and some roads still have water. When tires are used under such conditions, tires often burst due to pattern cuts, block drops, and even punctured treads. Phenomenon, reduce the service life of tires, and even lead to traffic accidents in severe cases, endangering life safety. [0005] Invention content: [0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of raw material composition of mine tire tread. [0007] Another object of the present invention is to provide a method for preparing the tire tread for mining. [0008] The invention mainly solves the probl...
