Abstract
The invention discloses one kind can colored laser carving polypropylene material, be made up of each component mixing extrusion of following weight percents：The 96wt% of polypropylene 92；The 8wt% of laser carving master batch 1；The 3wt% of colouring agent 0.5.Its preparation method comprises the following steps：After the polypropylene, laser carving master batch and colouring agent A or colouring agent B are mixed by constant weight percentage, by double screw extruder rotating speed be 180 500 revs/min, temperature be extruding pelletization and to carry out laser carving labeled test under the conditions of 180 230 DEG C.The invention is coloured to light laser carving by colouring agent and assigns its blueness and green two kinds of laser carving colors, the colorfulness of laser carving mark is extended on the basis of the basic black of polypropylene material of laser carving masterbatch colouration is kept, laser carving technology application is further expanded, meet higher packing instructions, and can be used without other additives directly as colored laser engraving material, easy to use and effect is good.
Description
Technical field
The present invention relates to a kind of high polymer material, and in particular to it is a kind of can colored laser carving polypropylene material and its preparation side
Method, belongs to field of high polymer material modification.
Background technology
Polypropylene (abbreviation PP) has excellent mechanical property, excellent bending resistance fatigability, good heat resistance, chemistry steady
Qualitative and electrical property, is most widely used general-purpose plastics, is widely used in plastic cement packaging industry.
In plastic cement packaging industry, laser carving labelling technique is increasingly risen.In recent years, using laser in plasthetics such as polypropylene
Surface carries out engraved markings and is widely applied, by adding laser carving master batch (such as Application No. 201410837554.7
Disclosed in Chinese invention patent it is a kind of be used for light color mark laser carving master batch) plastic material carry out laser irradiation, can be quick
Ground carries out various icon indicias.Wherein, laser carving polypropylene material is most widely used, but laser carving polypropylene can only carry out black,
The laser labelling of white and grey, the method laser carving of there is no goes out other colors, cause the mark color of laser carving polypropylene product single and
Lack visual attraction, limit the application extension of Laser marking technology.Therefore the laser labelling of laser carving polypropylene material is extended
Color, lifts the colorfulness and apparent visual effect of laser carving, has to the market competitiveness for strengthening laser carving polypropylene product
Significance.
The content of the invention
In order to solve the above technical problems, the invention provides one kind can colored laser carving polypropylene material, by following weight hundred
The each component mixing extrusion of ratio is divided to be made：
Polypropylene：92-96wt%；
Laser carving master batch：1-8wt%；
Colouring agent：0.5-3wt%.
Wherein, the polypropylene is homopolymerization type or copoly type, and melt index is 0.1-100g/10min.
Wherein, the laser carving master batch is the black laser carving master batch using polypropylene as carrier, contains metal oxide or modification
Silica, marker color is canescence.
Wherein, the colouring agent is colouring agent A or colouring agent B, the colouring agent A or colouring agent B composition are phthalocyanine face
Material, crystal type is a types or b types；Wherein, colouring agent A is phthalocyanine blue, and colouring agent B is phthalocyanine green.
The present invention it is a kind of can the preparation method of colored laser carving polypropylene material comprise the following steps：By the polypropylene,
After laser carving master batch and colouring agent A or colouring agent B are by the mixing of constant weight percentage, by the twin-screw extrusion that draw ratio is 32-68
Machine first paragraph cylinder is fed, rotating speed be 180-500 revs/min, temperature be extruding pelletization under the conditions of 180-230 DEG C.
By above-mentioned technical proposal, the present invention has the advantages that：
1. by being modified to polypropylene material, on the basis of with conventional light laser carving function, colouring agent is passed through
Light laser carving is coloured and its blueness and green two kinds of laser carving colors are assigned, the polypropylene material of laser carving masterbatch colouration is being kept
The colorfulness of laser carving mark is extended on the basis of the basic black of material, laser carving technology application has further been expanded, has met
Higher packing instructions；
2. colored laser carving polypropylene material of the invention can be used directly as colored laser engraving material, without other additions
Agent, easy to use and effect is good.
Brief description of the drawings
Fig. 1 is the laser carving labeled test figure of the embodiment of the present invention 1；
Fig. 2 is the laser carving labeled test figure of the embodiment of the present invention 2；
Fig. 3 is the laser carving labeled test figure of comparative example 1 of the present invention.
Embodiment
One kind of the present invention can colored laser carving polypropylene material, by each component mixing extrusion system of following percentage by weight
Into：
Polypropylene：92-96wt%；
Laser carving master batch：1-8wt%；
Colouring agent A or colouring agent B：0.5-3wt%；
Wherein, polypropylene is homopolymerization type or copoly type, and melt index is 0.1-100g/10min；Laser carving master batch is with poly- third
Alkene is the black laser carving master batch of carrier, and containing metal oxide or improved silica, marker color is canescence；Colouring agent is
Crystal type is the phthalocyanine color colouring agent A or colouring agent B of a types or b types, and colouring agent A is phthalocyanine blue, and colouring agent B is phthalocyanine green.
With reference to specific embodiment, the invention will be further described：
Embodiment 1：
Each component is taken according to above-mentioned formula, homogenizer is added to and is well mixed, is then 32-68's using draw ratio
Double screw extruder rotating speed be 180-500 revs/min, temperature be extruding pelletization under the conditions of 180-230 DEG C, that is, obtaining can colored radium
Polypropylene material is carved, laser carving polypropylene test bars are prepared finally by injection machine.
The preparation process be the same as Example 1 of embodiment 2 and comparative example 1.
