Problems solved by technology

[0008] The polymer materials used in the above patents all need to add cross-linking agents such as sulfur for vulcanization and cross-linking, and the formula and process are relatively complicated.
In addition, due to the large number of components, it is easy to bloom, and the environmental protection is not good

Embodiment 1

[0117] Step 1: Synthesis of SEBS

[0118] Step (1-a): Linear SEBS preparation:

[0119] Add 3000 milliliters of pure cyclohexane (water value<20ppm=1.2mL ditetrahydrofurfuryl propane (mixed with 0.5mol / L cyclohexane solution, the consumption is equivalent to 40mg / kg solvent), start stirring, raise the temperature to 60°C, then add 49mL styrene monomer and 1.5mmol n-butyl lithium respectively, polymerize for 30 minutes, then add 339mL butadiene monomer, and control the reaction by jacket water cooling The temperature is below 80°C, add 49mL styrene monomer after 40 minutes of reaction, and react for 30 minutes at a temperature of 60-65°C, and keep the pressure in the kettle at 0.1-0.5MPa during the whole polymerization process. After the polymerization reaction is completed, the glue The solution was introduced into a 10L hydrogenation tank, the temperature was raised to 70°C, 8mmol of n-butyllithium was added, and the reaction was terminated with hydrogen for 10 minutes. The...

Embodiment 2～4

[0133] Examples 2-4 Effect of linear rubber block ratio on rubber properties

[0134] Keeping other conditions unchanged, when synthesizing linear rubber, the effect of block ratio of linear rubber on the properties of rubber was investigated.

Embodiment 2

[0136] Compared with Example 1, the only difference is that in step (1-a), the block ratio (S / B mass ratio) is 25 / 35. Other conditions and components remain unchanged.

Abstract

The invention discloses a solid tread rubber material. The solid tread rubber material comprises linetype SEBS and starlike SEBS, and further comprises polypropylene, white oil, CaCO3, a wear-resistant agent, an antioxidant and an ultraviolet absorbent. The invention further provides a preparation method of the linetype SEBS, the starlike SEBS and the solid tread rubber material. In addition, theinvention further provides an application of the solid tread rubber material in preparing a solid tyre. Compared with a conventional pneumatic tyre, the solid tyre prepared by the formula material isanti-explosion and anti-puncture, enhanced in safety performance obviously, more excellent in wear resistance and rebound resilience and excellent in comprehensive physical performance. In addition, the formula material used for manufacturing the solid tyre is simple and energy-saving in manufacturing process and processing equipment. In the production process, no pollutants are discharged, and the rubber material can be repeatedly recycled, so that the rubber material is more environmentally friendly. The solid tread rubber material has a very wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer synthetic materials, and in particular relates to a solid tire compound of styrene thermoplastic elastomer rubber and the application of the compound to prepare a solid tire. Background technique [0002] Driven by the sharing economy, Internet shared bicycles came into being in 2014. The emergence of shared bicycles has brought a "second spring" to bicycle factories. According to the official website of the China Bicycle Association, since 2016, shared bicycles have been launched in more than 300 cities across the country, with a total of more than 20 million bicycles. It is estimated that in 2017, the scale of users in the shared bicycle market will continue to maintain substantial growth, reaching 50 million users by the end of the year. [0003] In order to prevent problems that affect riding safety such as tire blowouts and artificial tire punctures, it is particularly important to apply no...
