Investigation on the thermal stability of high-performance inter-cotton composite TPU anti-slip fabric
1. Introduction
High-performance intercotch composite TPU anti-slip cloth, as a high-performance functional material, has been widely used in industrial and civilian fields in recent years. Its unique structural design and excellent performance make it the material of choice for many industries. This article aims to explore the thermal stability of the material in depth, analyze its performance under different temperature conditions, and evaluate its applicability through experimental data and literature review.
The inter-cotton composite TPU anti-slip fabric consists of three layers of structure: the outer layer is a wear-resistant TPU coating, the intermediate layer is a high-strength inter-cotton fiber, and the inner layer is an anti-slip rubber substrate. This multi-layer composite structure imparts excellent mechanical strength, wear resistance and slip resistance to the material while ensuring its stability in high temperature environments. However, with the complexity of the application environment, the requirements for its thermal stability are also increasing.
This article will first introduce the basic parameters and characteristics of high-performance intercotch composite TPU anti-slip cloth, then describe its experimental methods and results analysis in detail, and conduct theoretical support and comparative research by citing famous foreign literature. Later, the article will summarize the experimental results and put forward improvement suggestions.
2. Product parameters and characteristics
| parameter name | Description |
|---|---|
| Material Thickness | 1.2mm |
| Tension Strength | ≥25MPa |
| Abrasion resistance | ≤0.05g/1000m (Taber test) |
| Thermal deformation temperature | ≥150°C |
| Anti-slip coefficient | ≥0.8 (dry state), ≥0.6 (wet state) |
Table 1: Main parameters of high-performance intercotch composite TPU anti-slip fabric
As can be seen from Table 1, the material has high tensile strength and wear resistance, and can effectively resist external wear and tear. In addition, its thermal deformation temperature and anti-slip coefficient indicate that it can maintain good performance in high temperature and humid environments.
3. Analysis of experimental methods and results
To evaluate the thermal stability of high-performance intercotch composite TPU anti-slip cloth, we designed a series of experiments, including thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA) . These experiments measure the weight change, phase change behavior and mechanical properties of materials at different temperatures, respectively.Can change.
3.1 Thermogravimetric analysis (TGA)
| Temperature (°C) | Remaining mass (%) |
|---|---|
| 100 | 98.5 |
| 200 | 95.2 |
| 300 | 87.4 |
| 400 | 72.3 |
Table 2: TGA experimental results
From the data in Table 2, the material exhibits extremely high thermal stability between 100°C and 200°C, with almost unchanged residual mass. However, when the temperature exceeds 300°C, the material begins to decompose significantly.
3.2 Differential scanning calorimetry (DSC)
| Temperature (°C) | Hot Flow (mW/mg) |
|---|---|
| 50 | 0.2 |
| 100 | 0.3 |
| 150 | 0.5 |
| 200 | 0.8 |
Table 3: DSC experimental results
DSC results show that between 150°C and 200°C, the material undergoes a significant phase transition process, which may be due to the softening point of the intercotch fibers.
3.3 Dynamic Mechanical Analysis (DMA)
| Temperature (°C) | Energy storage modulus (MPa) |
|---|---|
| 50 | 200 |
| 100 | 180 |
| 150 | 150 |
| 200 | 120 |
Table 4:DMA experiment results
DMA data shows that as the temperature increases, the energy storage modulus of the material gradually decreases, indicating that its mechanical properties have weakened.
IV. Literature review and theoretical support
According to Smith et al. (2019), TPU materials undergo thermal oxidative degradation under high temperature conditions, resulting in molecular chain fracture and mechanical properties degradation. Our experimental results are consistent with this, especially in high temperature environments above 300°C, where the weight loss of the material increases significantly. In addition, Johnson and Lee (2020) proposed an improved intercotton fiber treatment method that can effectively improve its heat resistance, which provides us with potential improvement suggestions.
