Plastic product hydrographic transfer printing drying method

Abstract

The invention relates to the technical field of hydrographic transfer printing, in particular to a plastic product hydrographic transfer printing drying method. The plastic product hydrographic transfer printing drying method includes the following steps: A, plastic products obtained after hydrographic transfer printing are taken out from a water tank, and water spots on the surfaces of the plastic products are blown to be dry through an air-pressure air gun; B, hot air is blown to the surfaces of the plastic products with a hot air machine; C, the plastic products are placed into an oven for baking. By means of the drying method, after the plastic products obtained after hydrographic transfer printing are dried through the hot air machine, the plastic products are placed into the oven for baking, as the plastic products have been dried one time through the hot air machine before being placed into the oven, the plastic products only need to be baked for 4 min to 10 min in the oven, and the reject ratio of the plastic products can be reduced while the time is saved. By means of the drying method, the baking time is shortened, and the production efficiency is improved; in addition, the reject ratio caused by baking deformation is reduced, and the good social benefit and the good social benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of water transfer printing, in particular to a drying method for water transfer printing of plastic products. Background technique [0002] Three-dimensional coating water transfer printing technology uses three-dimensional coating water transfer printing film to transfer patterns to various materials, for example, plastics (such as acrylonitrile-butadiene-styrene fiber, polymethyl polyaniline, polyvinyl chloride , polyurethane, polymethyl methacrylate), rubber, wood, metal, glass, nylon and ceramics. The three-dimensional coating water transfer film generally includes a pattern layer and a carrier layer, the pattern layer is an ink layer, and the carrier layer is a water-based film such as a polyvinyl alcohol (PVA) film. The three-dimensional coating water transfer printing method generally includes laying the pattern layer of the three-dimensional coating water transfer film upward on the water surface, ...

AI Technical Summary

Problems solved by technology

[0003] Due to the adsorption performance of the film, the plastic product usually needs to be baked in the oven for 45-60 minutes after the transfer is completed.

However, baking plastic products in an oven up to 75°C for such a long time will easily deform the plastic products, especially for some soft materials, and also cause an increase in the defective rate of plastic products.
