Abstract

The present invention belongs to the field of ink, and in particular relates to highly wear-resistant PU ink for silicone rubber surface. The raw materials comprise hydroxyl-terminated polyurethane resin, curing agent, and mixed solvent. Moreover, the raw materials still comprise wear-resistant additives. The wear-resistant additives can be one of or the mixture of a plurality of polytetrafluoroethylene, polypropylene, polyethylene, polyethylene oxide, zinc oxide, alumina oxide, iron oxide, zirconium oxide, magnesium oxide, calcium carbonate, talc, silica aluminum, and magnesium silicate. With the proposal of the present invention, the suitable polyhydroxylated PU resin, curing agents and filler are used to prepare PU ink for silicone rubber of convenient construction, reduction of priming payer of middle coating, good adhesion and excellent wear resistance.

Description

Technical field: [0001] The invention belongs to the field of inks, in particular to a highly wear-resistant PU ink used on the surface of silicone rubber. Background technique: [0002] As we all know, silicone rubber has the advantages of good elasticity, good weather resistance, and is not easy to age. It is a good material for making mobile phones and remote control buttons, but it also has a fatal flaw that is poor mechanical properties. The font and pattern on the surface of the buttons are easy to wear , so it is necessary to apply a layer of wear-resistant coating for protection. [0003] One of the outstanding characteristics of polyurethane is its excellent abrasion resistance. Chinese patent 96101893 once reported the polyurethane-based protective coating on the surface of silicone rubber, but it first needs to carry out plasma treatment on the surface of the substrate, then coat a layer of intermediate primer layer, and then coat polyisocyanate compound and poly...
