Method for improving surface decorative quality of nylon material workpiece

Abstract

The invention discloses a method for improving surface decorative quality of a nylon material workpiece. The method comprises the following steps of: 1, uniformly coating a polypropylene resin solution on the surface of the nylon material workpiece, uniformly spraying a polyester paint layer and roasting the surface of the workpiece; 2, covering a die cover carved with various design patterns on the surface of the workpiece, spraying alloy airing oil to the die cover for airing by using a small spray gun; 3, performing transfer printing or silk-screen printing of patterns or characters of various colors through a common alloy, and performing transfer printing through oil paint without an aid; and 4, adhering a color film. The surface of the nylon material workpiece and the polyester paint are adhered by employing the polypropylene resin solution, the workpiece is not worn, and the quality of the sprayed base paint is improved; the alloy airing oil layer is uniformly sprayed on the surface of the workpiece, the excessive alloy airing oil splashing to the workpiece outside a die frame can be removed at any time, and the product yield is improved; and moreover, the workpiece subjected to die spraying through the small spray gun is subjected to transfer printing or silk-screen printing by using the oil paint without the aid, and the residual oil paint can be recycled, so that the energy is saved.

Description

technical field [0001] The invention relates to a method for decorating the surface of a nylon material workpiece, in particular to a method for improving the surface decoration quality of a nylon material workpiece. Background technique [0002] Nylon materials have the advantages of heat resistance and folding resistance after surface decoration to make toys, handicrafts and collections. At present, the production process of using nylon materials to make toys, handicrafts and collections after surface decoration is: 1. Use sandpaper to roughen the surface of nylon material workpieces and then clean them with white electric oil or clean water to ensure that the surface of nylon material workpieces is sprayed with a background color The quality of the paint; 2. Use polyester paint to spray the pattern, and after spraying the pattern with polyester paint, it needs to be baked again at a high temperature of 140°C; 3. Use paint with additives for pad printing. And it must be p...

Problems solved by technology

The method disadvantage of adopting sandpaper to roughen the surface of the nylon material workpiece is that the operation is cumbersome, and the workpiece is easily worn to produce waste products; Erase, it is easy to produce waste products; the disadvantage of pad printing with additive paint is that it must be printed within 4 hours, otherwise the paint must be changed, waste materials, low work efficiency, poor product quality, and high production costs
