Problems solved by technology

[0002]Thermoplastic elastomers such as TPU have good appearance texture and mild touch, and have been widely used in the casings of a large number of electronic products such as mobile phones and computers. Difficult to paint on material, poor adhesion
The traditional method is to print the ink on the primer first, then spray a layer of elastomer after drying, so the rate of defective products is high
On the other hand, people have higher and higher requirements for products such as abrasion resistance and solvent resistance. While ensuring excellent adhesion of the product, they must also have good abrasion resistance and solvent resistance. inks that do not yet meet these requirements

Abstract

The invention provides ink. Based on the total weight of the ink, the ink is mainly prepared from the following ingredients in percentage by weight: 5-30% of epoxy resin, 10-40% of polyester resin, 0.5-2% of defoamer, 5-20% of wear-resistant emulsion and 40-60% of solvent. According to actual needs, the ink provided by the invention can also contain the following ingredients in percentage by weight: 0.5-2% of pigment and 0.5-2% of dispersant. The ink provided by the invention has relatively strong adhesion and wear resistance and good chemical resistance, and the resins and the solvent are relatively environmental-friendly, so that the ink is particularly applicable to an elastomer surface and has a good application prospect.

Description

technical field [0001] The invention relates to an ink, in particular to an ink suitable for the surface of an elastic body. Background technique [0002] Thermoplastic elastomers such as TPU have good appearance texture and mild touch, and have been widely used in the casings of a large number of electronic products such as mobile phones and computers. However, ordinary inks are difficult to coat on such materials and have poor adhesion. The traditional method is to print the ink first on the primer, and then spray a layer of elastomer after drying, so the rate of defective products is high. On the other hand, people have higher and higher requirements for products such as abrasion resistance and solvent resistance. While ensuring excellent adhesion of the product, they must also have good abrasion resistance and solvent resistance. The ink can not meet these requirements. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior ...
