Abstract

The present invention provides a thermal transfer film element comprising a weather resistant graphic layer. The weather-proof pattern layer comprises the following components in parts by weight: 1.0 to 2.0 parts by weight of acrylic resin, 2.0 to 4.0 parts by weight of polyvinylidene fluoride resin or fluoroolefin-vinyl ether copolymer, 1.0 to 5.0 parts by weight of inorganic pigment and 0.1 to 1.0 part by weight of additive. The thickness of the weather-proof pattern layer is equal to or greater than 3 [mu] m. The inorganic pigment presents a pattern. The heat transfer film element is attached to a workpiece, and the weather-proof pattern layer is dried at the drying temperature and then cured. The wear coefficient of the cured weather-resistant graphic layer is equal to or greater than 40.

Description

technical field [0001] The invention relates to a heat transfer film element, and in particular to a heat transfer film element which is attached to a workpiece and whose weather-resistant graphic layer has excellent abrasion resistance and weather resistance after curing. Background technique [0002] Building materials and other workpieces are generally decorated on the outer surface through the coating process. Taking the aluminum plate used for the outer wall of the building as an example, the outer surface of the aluminum plate will be cleaned first, and the aluminum plate will be immersed in a chromic acid solution to form on the outer surface of the aluminum plate. Chromate film and other pre-treatment processes. Some building materials and other workpieces whose surface needs to be modified, such as calcium silicate boards, bakelite boards, etc., will first clean the outer surfaces of these building materials and other workpieces in sequence, and then coat them on th...
