Description
Technical Field
The invention relates to rubber, in particular to an NBR rubber plate with high laser engraving efficiency and a preparation method thereof.
Background
The rubber offset plate, the rubber seal member and the rubber stamp can be manufactured by the laser engraving method. Ablation technique using laserAs a light source for laser irradiation, there are usually used an excimer laser of 193, 248 or 308nm laser, an Nd-YAG laser emitting light of 1.06um in wavelength, and a CO laser emitting infrared light of 10.6um2A laser. During laser irradiation of the polymer, the absorbed radiant energy is converted to thermal energy, and the localized heat generation causes the polymer chains to break down and further generates low molecular species that ablate away, forming the desired pattern.
Laser engraving of slabs has several advantages over conventional molding slab technology: the traditional molding rubber plate has complicated molding process, wherein the etching process needs to use corrosive chemical substances, thereby not only bringing about safety problems, but also polluting the environment. In contrast, laser engraving is the direct etching of computer-generated patterns on rubber plates. Except for generating some volatile decomposition products in the engraving process, only a ventilation system and a waste gas filtering system are needed to be arranged, and other pollutants are not discharged, so that the method is convenient, safe and quick.
With laser engraving at a fixed power, the processing speed is completely dependent on the rubber formulation. Therefore, the quality of the rubber formula directly influences the engraving efficiency.
Therefore, the development of the NBR rubber plate with high laser engraving efficiency is urgently needed, the engraving efficiency is improved, and the NBR rubber plate has a wide development prospect.
