Description
Technical field
The present invention relates to polymer modification field, more particularly to a kind of laser carving master batch, gathering containing the laser carving master batch
Propylene compositions and preparation method thereof.
Background technology
At present, the technology of printing mark is many on plastic goods, such as silk-screen printing, trans-printing, gold stamping.These sides
The equal metal surface printing of method, due to scraping or chemical contamination in commodity storage, handling process, causes mark to grind off or disappear, together
When the inefficient and high deficiency of cost also be present.With concern of the people to environmental protection, emerging laser labeling method just gradually takes
For above several prods labeling method.Laser marking is a kind of new labeling method, and the technology is swashed using the continuous of high-energy
Light beam is acted on frosting, is made the flash evapn of entry material, is caused entry material that Chemical Physics change occurs by luminous energy
Change, or moieties are burnt up by luminous energy, show the pattern and word of required etching, lacking for traditional character printing method can be avoided
Fall into, be widely used in each based article lettering.
Polypropylene material is using relatively extensively on household electrical appliance, and general household electrical appliances all use traditional surface printing technology at present,
Easily there is the phenomenon ground off in mark, has at present using laser marking technique to improve the fixing of mark, traditional " white with black
The blackness of the material of word " laser marking in itself is not black enough, the wrongly written or mispronounced character whiteness deficiency that laser marking comes out；If polypropylene material
Blackness and brightness increase, the wrongly written or mispronounced character that laser marking goes out is not white enough, not enough clearly, while in order to improve the Injection moldability of material
And various thin-walled property products applications are useful in, also there is higher requirement to the mobile performance of polypropylene material.If can solve
The glossiness of black polypropylene material, blackness, laser mark whiteness and definition, material flowability etc. take into account problem, material simultaneously
Material can be promoted and apply on high end home electric appliance casing.
The content of the invention

Flow rate ＞ 30g/10min.
A kind of preparation method of laser carving master batch as described above, it is to add each component to mix according to the weight percentage of raw materials
Conjunction machine is well mixed, and is then added in double screw extruder, the extruding pelletization after melt blending under 200~220 DEG C of processing temperatures.Enter
One step, the well mixed mixing time is 2~5min.
Another technical scheme for being taken of the present invention is：One kind can the high high brilliant black Polypropylene compositions of flowing of laser marking
Thing, it is based on parts by weight of raw materials including following component：
Wherein, described laser carving master batch is heretofore described using polypropylene as master batch carrier, including by raw material weight
Percentages account for the self-control laser carving master batch of the inorganic oxide of gross weight 15~25%.
As the further improvement of such scheme, the toner is by EG is red, 136 yellow, transparent purplish blue and the green compoundings of 5B form.
The toner utilizes red, yellow, primary colors toner system by composition material mixing color into black, and it uses carbon mother with traditional
Larger difference be present in the toner of system.Specifically, the toner in the present invention preferably by accounting for 34% according to the weight percentage of raw materials
EG is red, 16% 136 Huangs, 25% transparent purplish blue and the green compoundings of 25% 5B form.
As the further improvement of such scheme, the molecular weight of the C5 Petropols is 1500~2500, its softening point
For 110~120 DEG C.
As the further improvement of such scheme, the barium sulfate is through the surface-treated sulfuric acid of zinc stearate and EBS
Barium, it effectively improves the dispersiveness of barium sulfate, so as to optimize the combination property of polypropene composition.Specifically, barium sulfate
It is surface-treated as in closed high-speed mixer, 3min is handled under 100 DEG C of temperature conditionss after addition zinc stearate and EBS,
Wherein the addition of zinc stearate and EBS is respectively the 1% of the gross weight of not surface treated barium sulfate.Further, originally
Particle diameter≤7 μm of barium sulfate used by invention.
As the further improvement of such scheme, the acrylic resin in the composition in the laser carving master batch with adding
Acrylic resin it is identical, the HOPP resin from high-crystallinity, its melt flow rate ＞ 30g/10min.
As the further improvement of such scheme, the nucleator is aryl phosphoric acids salt nucleator.
As the further improvement of such scheme, the antioxidant is selected from Hinered phenols antioxidant, phosphorous acid esters antioxygen
