Pad printing ink for elastic paint surface decoration

Abstract

The invention discloses pad printing ink for elastic paint surface decoration. The pad printing ink comprises: be weight, 20 to 40% of a polyurethane resin, 15 to 30% of a modified polyester resin, 20 to 35% of one or two solvents, 5 to 35% of pigment, 0.1 to 5% of a dispersant and 0.1 to 5% of a defoaming agent. The one or two solvents adopted in the invention do not contain polycyclic aromatic hydrocarbons (PAHS) thus are environmentally friendly. After being baked at a temperature of 80 DEG C for 30 to 60 minutes, the pad printing ink coated on a rubber paint product and the surface of elastic paint has the characteristics of excellent adhesiveness, scraping resistance, alcohol resistance, aging resistance and wear resistance. The pad printing ink simplifies a decoration processing technology for elastic paint surfaces, improves production efficiency, reduces an unqualified rate of products, and provides multiple choices for enriching decorative designs and visual effects of elastic paint surface materials.

Description

technical field [0001] The invention relates to a pad printing ink, in particular to a pad-printable elastic paint surface decoration ink. Background technique [0002] With people's continuous pursuit of high-quality life, a large number of handheld mobile devices on the market use elastic paint, skin-like paint and other surface materials with delicate, smooth and comfortable touch for surface decoration; and the surface of such painted materials Ordinary printing ink has poor adhesion fastness. The traditional method generally adopts in-mold injection molding, and then coats elastic paint on the surface of the plastic part, which cannot meet the requirements of rich and diverse pattern design colors; , laser engraving and other processes, but inevitably bring problems such as discoloration, fading, damage to the corners of the pattern, and coating peeling off. [0003] Therefore, the prior art needs to be perfected and developed. Contents of the invention [0004] The...
