Embodiment 1

[0033] Step 1. Mix 80kg SEBS and 120kg industrial white oil according to the ratio in a container, stir and foam for 24 hours to form a mixed material for later use;

[0034] Step 2. Put the foamed mixed material into the reaction pot, heat it at a temperature of 250~280℃, for 20 minutes, stop heating and cool down when the mixed material melts, the cooled mixed material has become soft glue, and then crushed stand-by;

[0035] Step 3. Put 100kg of natural rubber, 2.5kg of sulfur, 0.5kg of accelerator DM, 2.5kg of stearic acid, 3kg of zinc oxide and 25kg of calcium carbonate into the reaction pot and heat it at a temperature of 250~280℃, and stop heating after 20 minutes , Cool to 100°C, add the soft glue processed in step 2, continue to heat and stir, wait until all the materials are melted, stop heating and cool to 190°C before spraying.

[0036] When spraying, the tire should rotate in a balanced manner at about 150 revolutions per minute, and the thickness of the spraying leak...

Embodiment 2

[0039] Step 1: Mix 70kg SEBS and 130kg industrial white oil according to the ratio in a container, stir and foam for 24 hours to form a mixed material for later use;

[0040] Step 2. Put the foamed mixed material into the reaction pot, heat it at a temperature of 250~280℃ for 30 minutes, stop heating and cool down when the mixed material melts, the cooled mixed material has become soft glue, and then crushed stand-by;

[0041] Step 3. Combine 100 kg of natural rubber, 1.5 kg of sulfur, 0.9 kg of accelerator DM, 1.5 kg of stearic acid, 5.2 kg of zinc oxide, 15 kg of calcium carbonate, 3 kg of pine tar, 0.30 kg of active light calcium carbonate, and 0.05 kg of accelerator TMTD , Antioxidant A1kg, Antioxidant D0.8kg, paraffin wax 0.5kg and petrolatum 0.1kg are heated in the reaction pot at 270℃, after 30 minutes, stop heating, cool to 110℃, add the soft rubber processed in step two, Continue to heat and stir, wait for all the materials to melt, stop heating and cool to 180°C before s...

Embodiment 3

[0043] The difference between Example 3 and Examples 1 and 2 is that 1.5 kg of cotton yarn fiber is added in step 3, the yarn count of cotton yarn is more than 40, and the length is 1 to 1.5 cm. The rest are the same as in Examples 1 and 2, respectively.

Abstract

The present invention relates to one kind of puncture resistant leak-less material for tyre without inner tuber and its preparation process. The material consists of two components mixed together, the component A consists of SEBS1 and white oil; and the component B consists of natural rubber, sulfur, promoter DM, stearic acid, zinc oxide and calcium carbonate. The preparation process includes the following steps: mixing SEBS1 and white oil and foaming the mixture; heating the mixture in a reactor, cooling and crushing; heating the materials of the component B, cooling, adding the crushed component A material, heating and cooling. The material for tyre has high heat resistance, high cool resistance, high oil resistance and high water resistance, and the tyre of the said material has no leakage and self repairing function.

Description

Technical field [0001] The present invention relates to anti-puncture and leak-proof materials for tubeless tires. It belongs to the technical field of organic polymer materials. Background technique [0002] Anti-stick tires are a kind of functional product developed in recent years. At present, on the market, you can also see some materials used for anti-stick tires, which can be roughly divided into: ①The type of tire structure changes (such as adding a thin steel plate in the tire); ②The liquid type (such as injecting a high-viscosity liquid seal into the tire) Dense material). From the perspective of feasibility and reliability, ①The structural change type must be put in the steel plate during tire manufacturing. Regardless of its reliability, it may not be feasible for multiple tire manufacturers; ②The liquid type will affect the safety of driving. Mainly will increase the vibration when driving. Summary of the invention [0003] The purpose of the present invention is to ...
