Description

Technical Field

[0001] This utility model relates to the field of mobile phone protective film technology, specifically a curved screen mobile phone protective film with self-healing properties. Background Technology

[0002] A screen protector is a thin film specifically designed to cover and protect a mobile phone screen. It aims to effectively prevent the screen from being damaged by scratches, impacts, dirt, and fingerprints during daily use. Its main functions and features include scratch resistance, impact resistance, fingerprint protection, improved visibility, and privacy protection. Curved screen protectors are specifically designed to cover and protect curved screen mobile phones, and they face unique challenges in terms of design and protection compared to ordinary flat screens.

[0003] Existing screen protectors cannot perfectly adhere to the phone screen. Ordinary screen protectors are relatively soft and can fit well with various curved screens, but they have a weak protective performance for the screen. They lack cushioning in the event of a collision or impact, making the screen fragile. They also do not provide good protection against scratches and friction from hard, sharp objects. This invention adopts a multi-layer structure design and self-healing technology, adding multiple protective film designs to effectively repair minor scratches and damage caused by collisions, thus providing better protection for the phone screen. Therefore, we propose a curved screen protector with self-healing properties. Utility Model Content

[0011] Compared with the prior art, this utility model provides a curved screen mobile phone protective film with self-healing properties, which has the following beneficial effects:

[0012] 1. This self-healing curved screen protector has a wear-resistant layer fixed to the top of the self-healing layer. The upper surface of the wear-resistant layer is coated with a nano-coating. The nano-coating enhances the wear resistance and impact resistance of the protector, thereby reducing the probability of damage to the self-healing material. A first protective film is fixed to the top of the wear-resistant layer. The first protective film protects the surface of the wear-resistant layer from scratches for the first time, and the nano-coating provides secondary protection.

[0013] 2. This self-healing curved screen protector consists of a polyurethane layer, a siloxane layer, and an isocyanate layer. The polyurethane layer has good elasticity and self-healing properties, the siloxane layer has good flexibility and environmental resistance, and the isocyanate layer has a self-healing network structure. An epoxy resin layer is fixed between the polyurethane layer and the siloxane layer, and the epoxy resin layer has good adhesion. An acrylic ester layer is fixed between the siloxane layer and the isocyanate layer, and the acrylic ester layer can form a new polymer network through a cross-linking reaction after being damaged.

[0014] 3. This self-healing curved screen protector consists of a flexible curved layer composed of a polyester film layer and a polyurethane film layer. The polyester film layer has good transparency and flexibility, which can adapt to curved shapes, while also having a certain degree of impact resistance and wear resistance. The polyurethane film layer is soft and has good elasticity and scratch resistance, and can recover a certain degree of deformation on its own, which helps to adapt to surfaces with high curvature. The polyester film layer and the polyurethane film layer are fixed together by a high-performance adhesive, which has a certain degree of thermal stability and durability.
