Embodiment 1

[0035] With 25.0g hexafunctional aromatic urethane acrylate prepolymer (Sinlimei Technology Co., Ltd., trade name: 670A2, functionality: 6), 10.0g photoinitiator (manufactured by Tianjin Tianjiao Chemical Co., Ltd., trade name: 184 ), 3.0g of leveling aid (BYK-UV3570, the molecular weight of the siloxane structure accounts for 80% of the molecular weight of the leveling aid), 10.0g of organic particles (polystyrene PS, particle size D1 is 15μm), 3.0 g of dispersant (BYK-111) and 49.0 g of ethanol were placed in a stirring pot, and stirred evenly to obtain a coating material.

[0036] The coating solution is coated on one side of a polycarbonate film with a thickness of 250 μm, dried for 3 minutes at an oven temperature of 120° C. 2 The coating was cured by UV light to obtain a matte hard coating with a coating thickness D2 of 3 μm. The evaluation results are listed in Table 1.

Embodiment 2

[0038]With 40.0g hexafunctionality aliphatic urethane acrylate prepolymer (Xinlimei Technology Co., Ltd., trade name: 230A2, functionality: 6), 2.0g photoinitiator (manufactured by Tianjin Tianjiao Chemical Co., Ltd., trade name: TPO ), 0.5g of leveling aid (BYK-371, the molecular weight of the siloxane structure accounts for 70% of the molecular weight of the leveling aid), 1.0g of organic particles (polymethyl methacrylate PMMA, particle size D1 is 16 μm), 0.2 g of dispersant (BYK-2008) and 56.3 g of methyl ethyl ketone were placed in a stirring pot, and stirred evenly to obtain a coating material.

[0039] Apply the coating solution to one side of a polyethylene terephthalate film with a thickness of 188 μm, dry it for 3 minutes at an oven temperature of 120° C. 2 The coating was cured by UV light to obtain a matte hard coating with a coating thickness D2 of 6 μm. The evaluation results are listed in Table 1.

Embodiment 3

[0041] 31.0g nine-functionality aliphatic urethane acrylate prepolymer (Sartomer, trade name: CN9013NS, functionality: 9), 5.0g photoinitiator (manufactured by Tianjin Tianjiao Chemical Co., Ltd., trade name: 1173), 2.0 g of leveling aid (BYK-3710, the molecular weight of the siloxane structure accounts for 90% of the molecular weight of the leveling aid), 1.5g of organic particles (polybutyl methacrylate PBMA, particle size D1 is 17.5 μm) , 0.5 g of dispersant (BYK-2000) and 60.0 g of ethyl acetate were placed in a stirring pot, and stirred evenly to obtain a coating material.

[0042] Apply the coating liquid on one side of a polymethyl methacrylate film with a thickness of 500 μm, dry it for 3 minutes at an oven temperature of 120° C. 2 The coating was cured by UV light to obtain a matte hard coating with a coating thickness D2 of 3.5 μm. The evaluation results are listed in Table 1.

Abstract

A release type hardening membrane comprises a supporter and a matt hard coating layer coated on the surface of the supporter, wherein the matt hard coating layer is prepared by curing a coating solution which is prepared from the following components in parts by weight: 25 to 40 parts of polyurethane acrylate prepolymer, 2 to 10 parts of a light initiator, 0.5 to 3 parts of a leveling agent, 1 to10 parts of organic particles, 0.2 to 3 parts of a dispersing agent and 40 to 60 parts of an organic solvent. The release type hardening membrane provided by the invention has a lower release force and is capable of preventing sticking of advertising stickers and adhesive tapes; meanwhile, the coating layer has scratch-resistant and anti-dazzle functions, so that the release type hardening membrane can be used for surface protection of solar cell panels of shared bicycles.

Description

technical field [0001] The invention relates to the field of thin films, in particular to a surface protection film for a solar battery panel used by shared bicycles. Background technique [0002] With the rapid development of the mobile Internet in the past two years, Internet shared bicycles led by Mobike and ofo have emerged as the times require. They are characterized by convenient and fast operation, energy saving and environmental protection, low price, and convenient "last mile" travel. Unstoppable tide. According to relevant data, in 2016, the overall number of users in China's shared bicycle market was nearly 19 million, and it is predicted that in 2017, the number of users in the shared bicycle market will reach 50 million. In the bicycle hardware, there are generally two ways for the shared bicycle power supply system to meet the smart lock and GPS positioning functions. One is to install a lithium battery in the bicycle lock, and the user drives the generator to...
