Description
Technical field
The present invention relates to a kind of polypropene composition that on dark-background, forms brilliant white (Huang) mark and preparation method thereof.
Background technology
In nearly all industrial sector, making marks to label on the production article becomes more and more important.For example, often need on article, indicate the trade mark, series number or the like of date manufactured, expiration date, barcode, company.
At present, the technological method that stamps mark on object is a lot, as printing technologies such as silk screen printing and trans-printing, embossing, impression, printing ink seals.These printing processes belong to surface printing, this just means is difficult to identification because physical abuse, rubbing effect, chemical action or similar effect make resulting identification marking to become, and this printing process is difficult to be applied to curved surface or net grain surface, and required special processing charges has increased the overall cost of product.
It also is well-known adopting laser system to come the benefit of marking objects: contactless property, high speed and flexible mark.For polypropylene articles, the result of lasing makes its surperficial carbonization or foaming, comes down to cause that by laser the variation of polypropylene surface has formed mark.Laser labeling method is such process: use laser, by with laser radiation target compound surface, literal, figure and symbol, barcode or image placed from the teeth outwards or the surface down.Laser labelling allow mark to be on the body surface or the surface down, mark is positioned at and helps mark under the body surface and remove the difficulty and false proof that becomes.In addition, the laser labelling technology can also be recorded in logotype such as barcode on nonplanar surface fast, makes the handiness of mark increase.Because it is the sign of laser labelling is to be recorded in the article itself, therefore wear-resisting lastingly.Laser seal target precision is big, this satisfied in addition littler plastics or metallic article on print the development need of mass data.For example, 10 times of two-dimensional bars to conventional barcode of packing density are studied out, compare with former barcode, print two-dimensional bar and require more accurate, more clear.Laser seal mark can satisfy these requirements, and in 0.001 inch scope, the size of point and position can be repeated---and these performance impressions or ink printer are difficult to realize.From the angle of protection environment, laser seal mark occupies very big advantage.Laser labelling need not printing ink, does not also need the such high strength energy drying process of printing ink seal mark technology, and it provides long lasting application; And it is solvent-free, makes it have more environment friendly.
Along with being on the increase of plastics in the productive life, the flexible marker that adopt laser, forms with the high speed noncontact has become more and more important.For having very sufficient contrast gradient between laser labelling on the plastics and the base material, could guarantee to use laser scanner or CCD photographic camera reading automatically like this to sign.
But, different plastic materials, its laser marking differs greatly, compare other thermoplasticss, polypropylene (PP) is a kind of material that is difficult to or even may adopt laser to mark, and in many cases, needs to add suitable additive, for example laser absorbent or laser photosensitizers make it to have laser labelling.
