Abstract: The water bestrow transfer printing technology, which has the advantages of simple forming and various patterns, can greatly enhance the visual effects of products. The ABS (Acrylonitrile-Butadiene-Styrene copolymer) plastic with heavy usage in the air-conditioning industry was used as the base material. The application of the water coating transfer process on the ABS base material was studied. The influences of the hydroxyl value of the primer, the water temperature of the transfer tank, the activation time, the angle of the workpiece transferring into the water and the hardness of the topcoat on the water coating effects were discussed. The research results show that when the primer resin hydroxyl value content is 6~15 mgKOH/g, the adhesion between the primer and the water bestrow film and the boiling resistance are better; when the water temperature in the transfer tank is 40~50℃, the activation time is 15~30 s, and the product water transfer angle is 30°~40°, the effect of water coating transfer pattern is the best; when the hardness of the topcoat is between HB and F, the boiling resistance and interlayer adhesion of the topcoat are better.
