Description
Technical field
The present invention relates to printing ink paint preparation field, particularly relate to a kind of ink that is applicable to the direct printing in polypropylene material surface and preparation method thereof.
Background technology
Acrylic plastering is polymerized by propylene monomer, it is colourless, tasteless, nontoxic a kind of non-polar high polymer compound, can be made into film and scleroid rigid plastics goods, while burning because of acrylic plastering, can not produce obnoxious flavour harm humans health and environment, therefore develop into gradually current topmost application material.In printing industry, the daily goods of polypropylene, packing bag, medicine equipment goods, industrial woven products etc. are all the important stock materials of a class.The feature of acrylic plastering is that polarity is low, degree of crystallization is high, and surface can be low, and stereoregularity is high, nature cohesive force is large, adopt general ink printing, altogether sticking power is poor, silk-screen again after the therefore conventional etching of complex acid mixed solution, surface grinding or plasma treatment.Need main equipment, treatment process is dangerous, contaminate environment.Each state has all dropped into the research that a large amount of manpower financial capacities carries out this respect, but all there is no thoroughly to solve the problem of polypropylene material poor adhesive force.A kind of screen printing ink for polypropylene plastic is disclosed in Chinese patent CN101469151B, in this ink, adopt thermoprene and Chlorinated Polypropylene III as resin matrix, being equipped with auxiliary agent, solvent, filler and pigment makes, this invention utilizes thermoprene the linear polymer chain of unsaturated double-bond to be transformed into the linear polymer chain containing special polynuclear plane in cyclization process, the molecular chain chap that obviously shortens, polarity also increases to some extent, thereby increases the cohesiveness of polyacrylic polymer material and ink; But in this invention, matrix composition is more, and preparation is complicated, and cost is higher.Chinese patent CN10220512A discloses a kind of containing PAHS(polycyclic aromatic hydrocarbons) screen printing ink for polypropylene material, this ink main component is chlorinated polyolefin resin liquid and vibrin liquid, although this ink is not containing PAHS(polycyclic aromatic hydrocarbons) reduced the harm to HUMAN HEALTH, its ink hardness is not good; China applies for a patent CN1063705A and discloses the screen printing ink for polytrimethylene that can be used for polypropylene film and hard product surface silk-screen that a kind of glue paste composition is Chlorinated Polypropylene III, acrylic resin, rosin modified phenolic resin, although this ink can be beneficial to silk-screen on acrylic plastering, the scratch resistance of ink, solvent resistance, resistance to deflection are not good.
Summary of the invention
For above-mentioned deficiency of the prior art, main purpose of the present invention is to provide printing-ink and preparation method thereof for a kind of polypropylene material, this ink is good to the sticking power of polypropylene substrate, easy to use and coating gloss, weathering resistance, wear-resisting, solvent resistance, resistance to deflection are all better, and ink environmental pollution is less, be suitable for a large amount of production and big area use.

Hundred lattice methods of testing: the test material that evenly scribbles ink is placed on testing stand, evenly draws 5 * 5 little grids of 1mm * 1mm with blade in test material, each line should be deeply and the bottom of ink; With hairbrush, the ink defragmentation of scribing edge is clean; With smooth the clinging of 3M adhesive tape, draw the tested district ink that has little grid; About 30-90, after second, with pointing firmly wiping adhesive tape, is bonded on the ink of test zone adhesive tape completely; With hand, catch adhesive tape one end, along test surfaces vertical direction, at 0.5-1, in second, shut down adhesive tape; Situation about coming off according to ink determines that whether ink adhesion is qualified, and satisfied 70% ink rete does not come off and reaches qualified.
While adopting above-mentioned degree of adhering to testing method in the present invention, test material is polypropylene material.
2, solvent resistance test mode: ink is evenly coated in material, keep 10 microns of ink film bed thickness, material is fixed on to loading 50g on microscope carrier, and cotton picks respectively test solvent: 90% ethanol, 50% ethanol, ethyl acetate, butanone, carry out the test of wiping back and forth.
Testing standard: need back and forth 50 need of wiping entirely not fade when cotton picks alcohol solvent; When picking ethyl acetate solvent, cotton need back and forth 20 need of wiping entirely not fade; When picking butanone solvent, cotton need back and forth 10 need of wiping entirely not fade.
3, glossiness test mode: instrument: KGZ-1C type glossmeter, adopt 60 ° of input angles of GB GB9754 test, every set product horizontal survey 5 times, averages.
4, hardness test: the scratch resistance of measuring ink with pencil hardometer: the panel of band coating is placed horizontally to paint film top layer, the pencil that utilizes different hardness grade with level angle at 45 ° approximately the power of 7.5 ± 0.1N at coating surface, move.The pencil that hardness is lower can produce one and write vestige on paint film, and the pencil that hardness is higher can produce an obvious cut on paint film, judges the hardness of paint film with pencil hardness.
5, resistance to deflection test: by the adhere firmly degree of resistance to deflection experimental examination ink and stock material.Ink of the present invention is coated on polypropylene base to polypropylene base thickness 0.2mm, ink film thickness 20 μ m.Method according to the test flexural fatigue strength of GB/T13557-1992 the 4th chapter regulation detects crooked 25 all after dates of polypropylene base (its crooked internal diameter should be 3mm), and whether the ink layer of observing on polypropylene base chaps, comes off; Without be full of cracks, without coming off, it is flexibility test passes.
According to above-mentioned testing method, choose above-described embodiment and test, test result is as follows:
The test data of each embodiment of table 1
By the test of ink product in embodiment in the present invention is shown: the properties of ink product of the present invention is to meet national standard, and the degree of adhering on polypropylene material of ink is better, solvent resistance good, resistance to deflection energy is good, scratch resistance good and glossiness is suitable, is beneficial to and is coated on polypropylene material.
Contrast experiment: other ink product in ink product in the embodiment of the present invention and prior art are compared:
Test group: the polypropylene material printing-ink that the embodiment of the present invention 2 is prepared;
Control group 1: the polypropylene material printing-ink of embodiment 2 preparations in Chinese patent CN101469151B;
