Anti-scratch mobile phone protection soft film and preparation method thereof

The invention discloses an anti-scratch mobile phone protection soft film and a preparation method thereof.The preparation method comprises the steps that modified resin emulsion and a methanol solution of copper chloride dihydrate are mixed to prepare a treating fluid, a modified base film is soaked in the treating fluid after being subjected to corona treatment, and the modified base film is taken out and dried to prepare the anti-scratch mobile phone protection soft film; imidazole groups on modified resin molecules are matched with copper ions to form coordinate bonds, after slight scratches appear on the surface, a surface coating film can be self-healed in a normal temperature state, the situation that the appearance and use of the protective film are affected by scratches is avoided, the modified resin molecules contain borate groups and a large number of reversible hydrogen bonds which are matched with metal coordinate bonds, and therefore the protective film has a good application prospect.
