TPE Material Development Case: Application of TV85B-JQRLD Black in Robot Vacuum Cleaner Tracks
Time of issue:2025-06-14
I. Material Characteristics
- High elasticity TV85B - JQRLD black tires exhibit excellent elasticity, enabling them to adapt to the sweeping robot’s operational requirements on various floor surfaces and terrains. When encountering obstacles or uneven ground, the tracks can flexibly deform to absorb impact, ensuring smooth operation of the robot.
- Good wear resistance The tracks of robotic vacuum cleaners frequently roll and rub against various types of flooring. To enhance the wear resistance of these tracks, the material has been modified with wear-resistant additives such as alumina microsphere powder and modified boron nitride powder. These additives significantly improve the material’s wear resistance, enabling it to withstand prolonged use without easily wearing down and thereby extending the service life of the tracks. 。
- Age resistance By adding additives such as antioxidants to the formulation, TV85B - JQRLD black exhibits excellent aging resistance, maintaining stable performance over long-term use. It is less likely to undergo aging, embrittlement, or hardening due to factors such as exposure to light, oxygen, and temperature fluctuations, thereby ensuring that the track maintains normal operation under various environmental conditions. 。
- Black exterior advantages The material is black and features dirt resistance and easy cleaning, ensuring that the robot vacuum’s tracks maintain a good appearance during daily use. This reduces the hassle associated with frequent cleaning and also enhances the overall aesthetic appeal of the product. 。
II. Application Advantages
- Good ground adaptability When operating, robot vacuum cleaners need to navigate across various floor surfaces, such as wood floors, tiles, and carpets. The black track made of TV85B - JQRLD material, with its high elasticity and appropriate hardness, provides excellent grip and adhesion on different types of flooring, ensuring stable movement and reducing the likelihood of slipping. Even on slippery surfaces, its superior anti-slip performance effectively prevents the robot from sliding or losing control, thereby enhancing its environmental adaptability and operational efficiency. 。
- Shock absorption and noise reduction The TPE track with excellent elasticity can absorb shocks during the robot’s movement, reducing the transmission of vibrations caused by uneven surfaces or collisions to the robot’s body itself, thereby minimizing noise generation. This not only makes the sweeping robot quieter during operation, enhancing the user experience, but also reduces interference with the surrounding environment.
- Protect the ground This material has a soft texture and will not scratch or wear down flooring surfaces such as wood floors or tiles. It is especially suitable for high-end home interiors, effectively cleaning while safeguarding the integrity and aesthetic appeal of the floor.
3. Production Process
- Raw material mixing The various raw materials—such as SEBS, polypropylene, filler oil, wear-resistant agents, and antioxidants—are precisely mixed according to specific proportions. During the mixing process, equipment such as high-speed mixers must be used to ensure that all raw materials are uniformly dispersed, thereby guaranteeing consistent performance of the final product.
- Internal Mixing and Extrusion The mixed raw materials are fed into a closed-milling machine for intensive mixing, where they are thoroughly blended and reacted under the influence of high temperature and shear forces, resulting in a TPE compound with excellent performance. Next, the compounded rubber is extruded into the desired track shape using a screw extruder. During the extrusion process, it is crucial to strictly control parameters such as temperature, pressure, and extrusion speed to ensure dimensional accuracy and surface quality of the tracks.
- Molding and Post-processing After extrusion, the tracks are formed through a mold to meet the specified dimensional and shape requirements. Once formed, the tracks may undergo several post-processing steps, such as cooling, cutting, and surface treatment, to further enhance their performance and quality. For example, the track surface can be polished or coated to improve its wear resistance and corrosion resistance.
