Problems solved by technology

Especially in the automotive surface coating industry, the commonly used coating materials in my country are generally TPU materials. The effect of glue is not good and it is easy to delaminate, and when TPEE is directly used as the coating material, the light transmittance of the TPEE film is worse than that of the TPU film.

Embodiment 1

[0022] 100 parts of TPEE resin, 60 parts of polyether TPU resin, 20 parts of PC, 5 parts of compatibilizer, 30 parts of filler, 3 parts of coupling agent, 15 parts of lubricant, 3 parts of antioxidant, 5 parts of plasticizer,

[0023] The addition of polyether TPU resin in the above ratio is mainly to improve the light transmission performance of the TPEE film after film formation and to improve the overall impact resistance of the base film and self-recovery ability after scratching. Together with PC resin, it forms an alloy material with good mechanical properties, excellent weather resistance and good appearance.

[0024] The nano-scale talcum powder and nano-scale silicon-aluminum salt in the filler are compounded according to a ratio of 2:1, wherein the function of the talc powder is to improve the crystallization nucleation performance during processing, and the silicon-aluminum salt can improve the surface after film formation. Performance, improve the effect of the fil...

Abstract

The invention discloses a TPEE base film of an automobile protective film. The TPEE base film of the automobile protective film comprises the following components in parts by mass: 100 parts of TPEE resin, 50-60 parts of polyether TPU resin, 10-20 parts of PC, 2-5 parts of a compatilizer, 15-30 parts of a filler, 1-3 parts of a coupling agent, 5-15 parts of a lubricant, 1-3 parts of an antioxidant and 1-5 parts of a plasticizer. The materials are subjected to honey refining and mixing, extrusion granulation and tape casting to prepare a base film finished product, and in this way, the prepared finished product is smooth in surface, free of miscellaneous points and water waves, excellent in light transmittance performance and good in tolerance to extremely cold and high-temperature weather.

Description

technical field [0001] The invention relates to the field of elastomer films, in particular to a TPEE base film of an automobile protective film. Background technique [0002] Thermoplastic polyester elastomers (TPEE) are block copolymers containing polyester hard segments and polyether soft segments. Among them, the polyether soft segment and the uncrystallized polyester form an amorphous phase, and the polyester hard segment partially crystallizes to form a crystalline microdomain, which acts as a physical crosslinking point. TPEE has the elasticity of rubber and the strength of engineering plastics; the soft segment gives it elasticity, making it like rubber; the hard segment gives it processing properties, making it like plastic. Compared with rubber, it has better processing performance and longer service life; compared with engineering plastics, it also has the characteristics of high strength, but better flexibility and dynamic mechanical properties. In addition to ...
