Description

Technical Field

[0001] The utility model relates to the technical field of TPO materials, in particular to an impact-resistant TPO material. Background Technique

[0002] TPO (Thermoplastic Olefin) is a thermoplastic elastomer composed of a blend of polypropylene (PP) and EPDM (ethylene-propylene-diene copolymer) rubber. It is widely used in the fields of the automotive industry, construction industry, household appliance industry, etc. TPO materials play an important role in the field of engineering plastics and are excellent-performance and widely-applied thermoplastic elastomer materials.

[0003] In the utility model patent with the patent authorization announcement number CN214111806U, a TPO waterproof coil is disclosed, which relates to the technical field of waterproof coils. It solves the problems that in order to ensure the vertical neatness of the lap joint of the coils, an auxiliary device is needed for measurement, the whole process is cumbersome, reducing the efficiency of the staff, and the top and side of the lap joint gap of the two coils are exposed to the air and are eroded by the external environment for a long time, resulting in local degumming of the gap and finally the complete loss of the waterproof function of the entire connected layer, with serious losses. The key points of its technical solution are in claim 1, and the effect is that by setting a reserved space and a second protective layer extending to the left, when the two coils are lapped, curves and hidden gaps appear, and at the same time, the sides of the gaps are blocked and protected, reducing the erosion degree of external environmental substances on the gaps, avoiding the loss of waterproof function caused by local degumming of the coils, and improving the practicability of the device.

[0004] However, the existing TPO materials also have certain deficiencies. The existing TPO materials are mostly composed of a blend of polypropylene (PP) and EPDM (ethylene-propylene-diene copolymer) rubber. Due to the limitations of the materials of polypropylene (PP) and EPDM (ethylene-propylene-diene copolymer) rubber themselves and other factors, the impact resistance and tear resistance of TPO materials are relatively weak.
