Thermal transferpowder coating will not change the physical and chemical properties of the original coating such as hardness, wear resistance, impact resistance, salt spray resistance, aging resistance, etc. At present, thermal transfer is mainly used for pattern printing of ski sports products. Printing technology, but the existing thermal transfer powder coating is mainly based on polyurethanesystem, but the effect is better, but the price is expensive and the cost is too high

Abstract
The invention provides thermal transfer printing coating. The thermal transfer printing coating is characterized by being from the following components in parts by mass: 200 to 400 parts of polyesterresin, 20 to 50 parts of TGIC (Triglycidyl Isocyanurate), 3 to 8 parts of a flatting agent, 1to 3 parts of benzoin, 1 to 3 parts of a brightener, 1 to 3 parts of waxpowder, 0.5 to 1 part of an accelerant and 1 to 3 parts of a pigment. According to the thermal transfer printing coating, the curing degree and crosslinking density of the adopted polyester resin under the same condition are better than those of other products; the polyester resin is cured for 10min under the condition of 200 DEG C and a coating layer can be sufficiently cured, so that phenomena that the surface of the coating layer is damaged through paper adhering, oil printing and the like, which are caused by the fact that the coating layer is heated and is subjected to secondary short curing in a high-temperature transferprinting process, are reduced; the thermal transfer printing coating is low in cost and simple to manufacture.
Description
technical field [0001] The invention belongs to the technical field of powder coatings, and in particular relates to thermal transfer printingpowder coatings. Background technique [0002] In recent years, thermal transfer printing technology has achieved rapid development in the aluminum profile market. Powder coating thermal transfer technology is a special process that sublimates the transfer printing ink on high-precision paper into the interior of the coating at a fixed temperature, so that the profile can be printed with the required pattern effect. Thermal transferpowder coating will not change the physical and chemical properties of the original coating, such as hardness, wear resistance, impact resistance, salt spray resistance, aging resistance, etc. At present, thermal transfer is mainly used for pattern printing of ski sports products. Printing technology, but the existing thermal transfer powder coating is mainly based on polyurethanesystem, but the effect i...
