Abstract
The invention relates to a master batch with the function of plastic laser marking, belonging to the field of laser marking technology. The master batch is prepared by the following components by weight percent: 10-25% of photosensitizer, 10-15% of white pigment, 20-30% of black pigment and 38.5-53.5% of organic polymer carrier. Before being formed by injection molding, the master batch is evenly mixed with plastic particles in a mechanical way, so that clear white pattern or handwriting can be generated on the surface of black PP type plastics, the self physical property of the material is not changed after the reaction, and the black PP type plastics which is suitable for laser marking can be obtained.
Description
Technical field
The invention belongs to the laser marking technical field, be specifically related to a kind of master batch with function of plastic laser marking.
Background technology
Laser marking is a New Processing that grows up after application technologies such as laser weld, LASER HEAT TREATMENT, laser cutting, laser boring, is a kind of noncontact, pollution-free, the new marking process that do not have wearing and tearing.In recent years, the raising along with reliability and the practicality of laser instrument adds the improvement of computer technology rapid development and optics, has promoted the development of laser marking technology.
Laser marking is to utilize the laser beam of high-energy-density to interacting goals, makes the variation of target surface generation physics or chemistry, thereby obtains the mark mode of visible pattern.High-octane laser beam focuses on the material surface, and material is vaporized rapidly, forms pit.Control cut-offfing of laser simultaneously along with laser beam moves regularly at material surface, laser beam also just has been processed into an appointed pattern at material surface.Laser marking has been compared tangible advantage with traditional marking process: (1) is permanent: can not disappear because of environmental concerns (touch, acidity and subtracting property gas, high temperature, low temperature etc.) as mark.(2) antifalsification: the mark that adopts the laser marking technology to carve out is not easy imitated and change, has very strong antifalsification to a certain extent.(3) untouchable: laser index carving is to process with the finishing tool of on-mechanical formula, can be at any rule or irregular surface franking, and workpiece can not produce internal stress after the mark, guarantees original precision of workpiece.Working surface is not produced corrosion, no tool wear, nonhazardous, pollution-free.(4) applicability is wide: do manufacturing process with laser, and can be to multiple metal, nonmetallic materials processing.(5) engraving precision height: the article figure line of laser marking machine engraving is meticulous, and minimum feature can reach 0.04mm.Mark is clear, lasting, attractive in appearance.Laser seal mark can satisfy the needs of printing mass data at minimum plastic part.For example, it is more accurate to print requirement, and the two-dimensional bar code that definition is higher is compared with impression or injection mark mode, and the stronger market competitiveness is arranged.(6) operating cost is low: the fast and mark one-shot forming of mark speed, energy consumption is little, thereby operating cost is low.Though the equipment investment of laser marking machine is bigger than conventional tag equipment, say from operating cost, use laser marking confidential much lower.(7) working (machining) efficiency height: the laser beam under the computer control can high-speed mobile (speed reaches 5～7 meter per seconds), and the mark process can be finished in the several seconds.(8) development rate is fast: because the combination of laser technology and computer technology, the user is as long as programming on computers can realize laser printing output, and conversion printed design at any time, fundamentally substituted traditional Mold Making process, for shortening updating and upgrading of a product cycle and the flexible production instrument of providing convenience.
Though laser marking has many good qualities, its limitation is also arranged, being considered to " the energy laser marking " polymer is those materials that can absorb the laser of respective wavelength and light is converted into heat energy.Yet many plastics (as polyolefin) up to the present also can not utilize laser to carry out mark.Send the CO of 10.6 microns infrared lights
2Laser instrument even under the very high situation of power output, the laser that sends also just produce mark fuzzy, that almost can not identify at polyolefin.And the light beam that most of polymer sends carbon dioxide laser is " transparent " all more or less---this means the laser beam penetrable material and be not absorbed.Some filler (glass, mineral) in addition, fire retardant and reground particle can both weaken printing performance greatly, thereby influence the definition of laser printing mark.
Summary of the invention
The technical problem to be solved in the present invention is that existing TPO plastics can not be by the technical problem of laser marking; a kind of master batch with function of plastic laser marking is provided; even with the plastic grain mechanical mixture before injection mo(u)lding; thereby can make at black PP class frosting and produce white pattern or writing clearly; and the physical characteristic of material itself can not change after reaction, thereby obtains being suitable for the black PP class plastics of laser marking.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Master batch with function of plastic laser marking of the present invention, it is prepared by following component by weight percentage:
Sensitising agent 10～25%
Chinese white 10～15%
Black pigment 20～30%
Organic polymer carrier 38.5%～53.5%.
Described sensitising agent is the sensitising agent that the laser of 10.64 mum wavelengths is had the strong absorption effect.
Described sensitising agent is sensitising agent LS.
Described Chinese white is any one or two or more the mixture in mica, calcium carbonate, barium sulfate, titanium dioxide, magnesium sulfate, calcined kaolin, lithopone, the stibium trioxide.
Described black pigment is carbon black.
Described organic polymer carrier is a kind of in polyethylene or polypropylene or the polyethyl acrylate.
All components by double screw extruder fully mix, extrude, granulation, the specification of particle is identical with plastic grain.Even with the plastic grain mechanical mixture before injection mo(u)lding, addition is 4%.
The employed sensitising agent of master batch with function of plastic laser marking of the present invention has strong absorption to the laser of 10.64 mum wavelengths; sensitising agent effectively absorbs laser beam energy; thereby generation high temperature makes surface black pigment become gas evaporation exposes the deep layer Chinese white, thereby produces contrast strong white writing or pattern at black PP frosting.The specification of the particle of functional master batch of the present invention is identical with plastic grain, is easy to realize and the abundant mixing of plastic grain, in production application, is easy to use and operate.The relative low price of functional master batch of the present invention, the particularly application on the big moulding of similar auto parts and components are compared with leakage printing process with traditional labelling, and cost advantage is obvious.Marking effect is good, and white writing or pattern and the contrast of black plastic background color are obviously.
