Abstract
The invention provides a laser colored marking method. Metal is added into pre-marking material which can achieve colored marking effect under laser irradiation through different degrees of oxidation of the incorporated metal material on the surface of the pre-marking material. The laser colored marking method adopting adding metal material into the pre-marking material realizes colored marking ofthe pre-marking material, and the laser marking is widely applied because of having the advantages of good performance of environment protection, fast speed and low energy consumption.
Description
Technical field
The present invention relates to a kind of colored marking method, particularly relate to a kind of in the preliminary making material laser colored marking method of doping metals powder.
Background technology
The method of utilizing stainless steel to realize colour-coded is arranged in the prior art, and its way just is to use the laser irradiation stainless steel surface of varying strength, makes its surface generation oxidation in various degree, shows color in various degree.But on plastics, also do not have corresponding method to realize mark, can't meet the needs of production.Mainly be in plastics, to use metal oxide powder in the laser color labeling method on the plastics at present.
Prior art can realize that the method for nonmetallic materials colour-coded mainly is the principle of similar welding, adopts pigment powder, and perhaps its mixture is coated in and is labeled material surface, utilizes laser that powder is welded on body surface then.Newer method is to add metal oxide powder in plastic material, carries out colour-coded by laser irradiation oxidation, but this method technology more complicated still, and is especially obvious when carrying out multiple color mark.
Summary of the invention
The present invention the invention provides a kind of laser colored marking method of doping metals alloy powder in order to overcome above-mentioned the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of laser colored marking method is provided, comprise: pulverous metal mixes in the preliminary making material, it is characterized in that: described metal can generate the oxide of different colours under the formed oxidizing condition of the irradiation of different laser; Described preliminary making material is realized the effect of color marker by the oxidation in various degree of the described metal of its surface doping under the laser irradiation.
The scheme that the present invention solves further technical problem is: the described combination that has color marker to comprise that solid color forms has color marker.
The scheme that the present invention solves further technical problem is: the described combination that has color marker to comprise that any blend color of black, white, red, orange, yellow, green, blue, blue, purple forms has color marker.
The scheme that the present invention solves further technical problem is: described laser is all types of laser from infrared to ultraviolet.
The scheme that the present invention solves further technical problem is: described preliminary making material is transparent or opaque organic material.
The scheme that the present invention solves further technical problem is: described metal is Powdered.
The scheme that the present invention solves further technical problem is: described metal is an iron.
The scheme that the present invention solves further technical problem is: described preliminary making material is plastics.
The scheme that the present invention solves further technical problem is: described preliminary making material is a section bar, or film, or the coating material of liquid state or solid state powder shape.
Compared to prior art, laser colored marking method of the present invention adopts the method for doping metals material in the preliminary making material, realizes the color marker that has of material, and laser labelling is with its good environmental protection, and speed is fast, and advantage of low energy consumption is widely used.
The specific embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
Laser labelling is with its good environmental protection, and speed is fast, and advantage of low energy consumption is widely used.
Laser colored marking method of the present invention is to utilize the part metals powder under the oxidizing condition that different laser irradiations form, and generates the oxide of different colours, realizes the material technology of color marker with this.
As shown in Figure 1, the invention provides a kind of laser colored marking method, it comprises: doping metals in the preliminary making material, this preliminary making material has been realized the color marker effect by its surface doping metal oxidation in various degree under the laser irradiation.Described preliminary making material is generally plastics, pottery, polyester thing, or is transparent or opaque organic material, also can be section bar, also can be the coating material of liquid state or solid state powder shape.
Plastics have the processing that is better than metal, spray figure performance, even can produce transparent plastics, using also can be very extensive.With plastics is example, and above-mentioned metal dust under the irradiation of laser oxidation takes place, and when different metal dusts produces different degree of oxidations, can present different colors, thus realize this kind correspondence plastic material color marker arranged.Different laser degree of illumination also can produce different oxidation effectivenesses, and Dui Ying color also can be different naturally, also can realize color marker.
The described combination that has color marker to comprise the formation of solid color or black, white, any blend color of red, orange, yellow, green, blue, blue, purple has color marker.
Described laser is all types of laser from infrared to ultraviolet.
Described metal is Powdered.
Described metal is an iron.
Described degree of oxidation can be according to the degree of the irradiation of laser, as intensity, and time wavelength or according to the difference of the concentration of oxygen around it and difference.
In sum, laser colored marking method of the present invention adopts the method for doping metals material in the preliminary making material, realizes the color marker that has of preliminary making material, and laser labelling is with its good environmental protection, and speed is fast, and advantage of low energy consumption is widely used.
