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.

Example Embodiment

[0013] The present invention will be further described below in conjunction with specific embodiments.
[0014] The raw materials and weight percentages of the examples are shown in the following table:
[0015]
[0016] Among them, the preparation methods of Example 1, Example 2, Example 5, and Comparative Example 1:
[0017] Add the formulated amount of hydroxy polyurethane resin, zinc oxide/alumina/polytetrafluoroethylene/polyethylene oxide/aluminum silicate, closed diisocyanate trimer, and mixed solvent into a container to mix, and mix at 1000-1500 rpm It is prepared after a minute of high-speed dispersion evenly.
[0018] Preparation methods of Example Three, Example Four, Example Six, and Comparative Example Two:
[0019] Add the formulated amount of hydroxy polyurethane resin, zinc oxide/alumina/polytetrafluoroethylene/polyethylene oxide/aluminum silicate, and mixed solvent into a container and mix, and then disperse uniformly at a high speed of 1000-1500 revolutions/min to prepare agent A; Use the diisocyanate trimer of the formula amount as the B agent; just mix the A and B agents when in use.
[0020] Construction method:
[0021] Take the silicone rubber test piece (size: 3mm×50mm×15mm), remove the impurities on the test piece, and treat it with flame or electric discharge. The paint is filtered with 200-300 mesh filter cloth, sprayed, and the film thickness is controlled at 20-25 microns. After spraying, let it dry for 5 minutes, put it in a 150℃ oven, and bake it for 50-60 minutes. Take out the test piece, let it cool to room temperature, and test. The results are as follows:
[0022]
[0023] The above embodiments only list a few examples of wear-resistant additives such as polytetrafluoroethylene, zinc oxide, aluminum oxide, etc. The formulation and construction methods of other wear-resistant additives are similar to those of polytetrafluoroethylene, zinc oxide, and aluminum oxide. The formulation method and construction method of other anti-wear additives are the same, so I will not repeat them.
