Problems solved by technology

Although most of the ingredients can vary from polar to non-polar etc., conventional tire tread compositions are generally hydrophobic and therefore not suitable for the electrically conductive hydrophilic tires sought by the inventors

[0135] Preparation example. Preparation of tire composition

[0136] Tire compositions were prepared using the materials and composition ratios shown in Tables 1 to 4 below. Specifically, a rubber blend free of accelerators, activators and hardeners is mixed with a reinforcing agent (first mixing step). The accelerator, activator and / or curing agent are then mixed (second mixing step). The first mixing step was performed at about 90°C for 5 minutes and the second mixing step was performed at about 50°C for 2 minutes. In order to obtain optimum physical mechanical properties and obtain a homogeneous mixture, it is preferred to pass the rubber component and other ingredients through a two-roll mill for a controlled period of time.

[0151] Experimental Example 1. Water Swelling Experiment

[0152] Cut the sample into about 3cm×3cm, 2mm thick, weigh the initial weight, and weigh after absorbing water. The degree of expansion was calculated using the following calculation formula, and the results are shown in Table 5 below.

experiment example 2

[0156] Experimental example 2. Tensile strength experiment

[0157] According to the ASTM D412 standard, the tensile strength (TS) of samples (10cm×2mm×2.5cm) cured at a temperature of 25°C was measured using a QM100s machine (QMESYSTEM, Korea) at a crosshead speed of 500mm / min. Lock the tensioning machine at a distance of 2.5 cm from both ends of the sample, and spaced about 5 mm apart. In operation, the fixed end stretches the sample, so the stress is applied for the remaining 5 mm distance until the stress is released (highest tensile strength). After mechanically entering the thickness and area of ​​stress applied, graph the tensile strength in elongation (mm / mm) or strain (100%) and record at least three samples and record the average value. The results are shown in Table 5 below.

Abstract

The present disclosure relates to a tire tread compound having high conductivity, excellent wear resistance and absorption characteristics, and a method for manufacturing the same. Specifically, the present disclosure relates to the manufacture of a tire compound for use as a non-pneumatic tire, which reduces the water expansion coefficient compared to the prior art, thereby making it possible to manufacture a tire electrode having improved electrical conductivity and contact resistance with the ground while having wear resistance, and to manufacture a non-pneumatic tire. The electrode can be used as a moving electrode with a water supply tool capable of detecting a defect position of a buried conductor.

Description

technical field [0001] The present disclosure relates to a tire tread compound having high electrical conductivity, excellent wear resistance, and absorption properties, and a method of manufacturing the same. In particular, the present disclosure relates to the manufacture of tire compounds for use as non-pneumatic tires that can be used to detect damage from buried conductors (wires, pipes, etc.) A mobile electrode in the form of a tire at the location where the ground potential rises due to stray current leaking from structures (buildings, bridges, etc.). Background technique [0002] If defects in underground cables or gas pipelines are not detected early and repaired, voltage or gas may leak from the defect, potentially posing a threat to the environment. In addition, defects can cause electric shock or burns to people or animals, and can completely damage buried industrial equipment. [0003] And, since such leaks are wasteful, there is an economic loss. Causes of s...
