[0071] In a second aspect, a method for preparing the above-mentioned self-repairing oil-repellent coating is provided, comprising the following steps:
[0072] (a) earlier the polyhydric alcohol of formula quantity is mixed with solvent;
[0073] (b) add the auxiliary agent of formula quantity again and mix;
[0074] (c) Then add and mix the isocyanate, ultraviolet absorber and antistatic agent in the formulated amount to obtain the self-repairing anti-oil stain coating.
[0075] The preparation method of the self-repairing anti-oil pollution coating of the present invention is simple to operate and easy to implement. By mixing the raw materials separately, it helps to improve the uniformity of mixing, facilitates molding, improves stability, and then enhances the use performance of the material .
[0076] In the preparation of the self-repairing anti-oil stain coating, the above-mentioned raw material components can be mixed step by step at room temperature, and then store...

Abstract
The invention relates to a protective film with self-repairing and oil stain-preventing functions, in particular to self-repairing and oil stain-preventing coating and a preparation method thereof, and a protective film containing the same and a preparation method thereof. The self-repairing and oil stain-preventing coating is prepared from the following raw materials in parts by weight: 10-80 parts of polyol, 1-50 parts of isocyanate, 1-10 parts of an auxiliary agent, 0.1-10 parts of an ultraviolet light absorber, 0.01-10 parts of an antistatic agent and 1-50 parts of a solvent. The protective film sequentially comprises a first release film, the self-repairing and oil stain-preventing coating, a film substrate, an ultraviolet blocking pressure-sensitive adhesive layer and a second release film. The protective film has a more excellent self-repairing function, a more excellent oil stain-preventing function and more excellent weathering resistance, can be self-repaired at room temperature within a short time, and has a better protective effect.
Description
technical field [0001] The invention relates to a protective film with a self-repairing anti-oil stain function, which is particularly suitable for sticking on a paint surface or a glass surface for protection, in particular to a self-repairing anti-oil stain coating and a preparation method thereof, and a coating containing the coating Protective film and preparation method thereof. Background technique [0002] With the rapid heating up of domestic automobile market sales, more and more people buy vehicles, and cars have become a must-have item for the public to travel. At the same time, with the increasing number of new drivers and lack of experience, coupled with the increasingly congested urban traffic, bumps and bumps are inevitable, causing more after-sales problems. However, the non-original paint that has been added later will have problems such as color difference and easy peeling off. , and encounter environmental factors such as smog and acid rain, the paint sur...
