Abstract

The invention relates to code spraying ink for a tire and a preparation method thereof. The ink comprises the following raw materials in parts by weight: 10-25 parts of polyurethane resin, 15-50 parts of titanium dioxide, 0-10 parts of additive resin, 3-10 parts of an anti-settling agent and 150-500 parts of a solvent. The preparation method comprises the following steps: compounding the polyurethane resin and the titanium dioxide by using an extruder and preparing composite resin; putting all the solvents into a reaction kettle according to the formula requirements and agitating; keep agitating, adding the additive resin into the reaction kettle in sequence and agitating for 5-8 hours; slowly putting the composite resin into the reaction kettle after uniform mixing; adding the anti-settling agent into the reaction kettle and agitating for 2-3 hours; stopping and settling for above 12 hours when all solids are dissolved and uniformly mixed; measuring the contents of the solids and adjusting the contents to theoretical values; and weighing and packaging. Compared with the prior art, the code spraying ink has the advantages of good binding force, clear writing, no ink flying and the like.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a coding ink for tires and a preparation method thereof. Background technique [0002] Tires are one of the important parts of the car. They are in direct contact with the road surface, and work together with the car suspension to ease the impact of the car while driving, ensuring that the car has good seating comfort and smooth driving; ensuring that the wheels and the road are in good condition The adhesion of the tire improves the traction, braking and passability of the car; bearing the weight of the car, the important role played by the tire on the car has attracted more and more attention. The material of the tire is generally rubber. In order to improve the performance of the rubber tire, various patterns are printed on the surface of the tire. When the tire is extruded from the production material, it is necessary to roll the tire's specification model, producti...
