The rare-earth / rubber composite material easily subjected to laser engraving, provided by the invention, has the advantages that the quality of laser engraving can be guaranteed, the speed of engraving can be increased, the cost is reduced, and the absorption rate of laser is increased. The composite material is mainly prepared from the following ingredients in parts by weight: 100 parts of rubber, 1-200 parts of inorganic nano rare-earth compound, 0.5-80 parts of coupling agent, 0-10 parts of zinc oxide, 0-10 parts of stearic acid, 0-100 parts of reinforcing filler, 0-200 parts of flame retardant, 0-200 parts of flame-retardant synergist, 0.1-15 parts of cross-linking agent, 0-20 parts of accelerant, 0-20 parts of anti-aging agent and 0-100 parts of plasticizer, wherein the inorganic nano rare-earth compound is one or a randomly-proportioned mixture of more than two of nano rare-earth oxide, nano rare-earth chloride, nano rare-earth sulfide, nano rare-earth carbonate, nano rare-earth nitrate, nano rare-earth sulfate and nano rare-earth hydroxide, and rare-earth elements are selected from scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium.

Description

technical field [0001] The invention relates to a rare earth / rubber composite material that is easy to laser engrave. It is used to prepare a rare earth / rubber composite material that is easy to laser engrave. Medical treatment, etc., this kind of industry must involve laser engraving technology in the process of use. Background technique [0002] Laser has the advantages of good directionality, high energy density, and good monochromaticity, and is very suitable for material processing, so it has always been valued by scientific research and industry. [0003] Laser engraving refers to the use of laser beams to act on materials to cause changes in the shape or properties of samples. It is a high-power-density spot formed by focusing the laser beam. Within a few microseconds, the temperature of the spot area rises to the melting point or even the boiling point of the material, so that the material at the irradiated place is melted, vaporized, ablated or reached the ignition...

Problems solved by technology

There are two conventional methods: one is to reduce the incident power of the laser. This method can ensure that the laser engraving surface is smooth and reduce the degree of carbonization of the engraving surface, but the engraving depth decreases, and the time required for engraving the same depth increases, reducing the processing time. efficiency and increase cost; another method is to fill a large amount of flame-retardant fillers, which can improve the heat resistance of rubber and reduce the degree of carbonization of the engraved surface, but too much filling will cause the performance of rubber materials to decline and improve the performance of rubber. The cost of composite materials, and in order to achieve a good engraving effect, it is necessary to increase the power of the incident laser, which increases the cost of the equipment

Both approaches will reduce the absorption rate of the laser, and at the same time increase the product cost to a large extent
