Wear-resistant ink applicable to elastomers

Abstract

The invention discloses a wear-resistant ink applicable to elastomers. The wear-resistant ink applicable to elastomers is composed of the following components in parts by mass: 10-25 parts of polyurethane modified epoxy resin, 10-20 parts of phenolic aldehyde modified epoxy resin, 15-30 parts of saturated polyester solid resin, 5-15 parts of vinyl chloride-vinyl acetate resin, 15-30 parts of pigment, 40-55 parts of ethyl acetate, 5-10 parts of propyl acetate, 15-20 parts of nano aluminum trioxide wear-resistant emulsion anti-wear agent, 0.5-2 parts of anti-settling agent, 0.5-2 parts of dispersing agent, 0.5-2 parts of antistatic agent and 0.5-2 parts of defoaming agent. The wear-resistant ink is applicable to elastomers, can reduce the reject ratio in the elastomer printing process, is wear-resistant, and prevents the presswork from being worn easily. Besides, by using the antistatic agent, the wear-resistant ink has certain antistatic property.

Description

technical field [0001] The invention relates to the field of inks, in particular to a wear-resistant ink suitable for elastomers. Background technique [0002] Because thermoplastic elastomers have good appearance texture and mild touch, they 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. Print the ink first, then spray a layer of elastomer after drying, so the rate of defective products is higher. Moreover, this type of printing also requires that the printed matter has a certain degree of wear resistance, otherwise the printed matter will be easily worn off. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a wear-resistant ink suitable for elastic bodies, which can be applied to elastic bodies and is wear-resistant. [0004] In order to solve the above ...
