Meanwhile, the hardness and the mechanical strength of the TPU can be enhanced by the hard inorganic particles, so that the impact resistance of the car cover film is enhanced.
2. The silane coupling agent can improve the compatibility of the porous nano inorganic particles in the polymer, the polyhydroxy structure of the silane coupling agent can further enhance the hardness and the mechanical strength of the car cover film, and meanwhile, the branched structure of the silane coupling agent can enable the molecular chain structure of the TPU material to be looser, so that the damping performance of the TPU is enhanced, and the noise reduction and sound absorption effects of the car cover film are further enhanced. In addition, the hydrophobic group carried by the silane coupling agent can simultaneously weaken the moisture absorption of the TPU film, thereby preventing the ageing degradation of the car clothes film.
