Abstract

The invention relates to a preparation method for a film printing coating, belonging to the technical field of printing. According to the invention, fumed silica with high purity, good dispersity andstandard spherical particle shape is synthesized through gaseous detonation by using mixed gas of hydrogen and oxygen as a detonating source and silicon tetrachloride as a precursor, and the silicon hydroxyl group on the surface of the fumed silica is activated; a silane coupling agent is hydrolyzed to generate a dehydration reaction with the silicon hydroxyl group on the surface of the fumed silica, so an organism in the silane coupling agent is connected with the surface of the fumed silica; silane coupling agent modified fumed silica is dispersed into an adhesive cross-linked by waterborneacrylic resin and waterborne polyurethane in a cationic coating manner to prepare an ink-absorbing coating; the preparation method provided by the invention adopts the silane coupling agent modified fumed silica as a filling material, so ink-absorbing properties and glossiness of a coating are greatly reinforced; meanwhile, the adhesive cross-linked by the waterborne acrylic resin and the waterborne polyurethane facilitates improvement of bonding strength and wear resistance of the coating.

Description

technical field [0001] The invention relates to a method for preparing a film printing coating, which belongs to the technical field of printing. Background technique [0002] Compared with traditional printing paper, film printing consumables have many practical features such as high strength, good weather resistance, good tear resistance and durability, and are often used in high-quality photo printing, advertising consumables, medical printing films and high-end business cards. Wait. [0003] PET film printing materials are currently the most widely used type of film printing materials, of which laser printing and water-based inkjet printing are the two most important uses. [0004] PET film laser printing film refers to a printing film that can be used for laser printing by coating a layer of ink-absorbing coating on the PET film as the base material. Due to the good mechanical strength, high transparency, excellent electrical properties, high heat resistance temperatu...
