A kind of printable aqueous polyurethane 3D polishes or 3D ink
Technical field
The present invention relates to a kind of water color ink, particularly to a kind of printable aqueous polyurethane 3D polishes or 3D ink,
Belong to pad-ink technical field.
Background technology
Water color ink is made up of aqueous high molecular resin, pigment, water and cosolvent etc., and wherein water-based polyurethane ink is with it
The advantages of good wearability, adhesive force, solvent resistant, flexibility, heat resistance, simultaneously water color ink have safe and nontoxic harmless,
Do not fire not quick-fried, produce almost without VOC, improve the security of operating environment.Just constantly improve and open
Open up the field that is increasingly widely applied, the development and application of particularly suitable weaving and footwear material industry.The aqueous three-dimensional employing of tradition
Slab printing processing, needs the half tone of cooperation specialty, printing ink color matching is complicated, operation technological requirement is high, time-consuming;In the face of fierce city
Competition, social environment consciousness constantly strengthens, high cost, high energy consumption, pollution environment, or even the exceeded product of venomous injurant is
Do not adapt to the needs of social development, be eliminated out market the most at last.
Aqueous polyurethane 3D ink is generally divided into colored ink and 3D polishes, and 3D polishes is transparent no any covering
Power, its firmness is good, for bottoming.Colored ink passes through computerized color matching, is printed upon 3D polishes, is not required to make half tone, by adjusting
Whole printing device can be with different pattern and effect.Versatility is wide, bright in luster have flexibility, color of can arbitrarily mixing colours, vision is imitated
Really good, there is no restricted performance characteristic effect.Can follow one's bent what design was wanted oneself.Produce aqueous vertical slab rubber cement at present
Based on acrylic emulsion and polyvinyl acetate (VAE) emulsion, because technical requirements threshold height is different, production technology is simplified and traditional
Differ, the quality causing a lot of rubber cements on the market is uneven, aqueous slab rubber cement generally existing Boardy Feeling, poor flexibility, easily
After-tacking, poor heat resistance, cold short hot sticky, resist bending is bad, resistance to water wash water firmness is poor simultaneously, gambling the shortcomings of net, thus limiting
Range of application starched by slab, brings technical barrier to numerous footwear materials and textile industry producer.In sum, current water color ink
It is all serigraphy, before printing, half tone complex manufacturing technology, take, need to put into a large amount of man power and materials;Meanwhile, at present
Aqueous can be with water-borne acrylic resin as carrier with pad-ink, brittle cracking, poor adhesive force, not wear-resisting, fade, intolerant to
Washing.
Content of the invention
The defect existing for existing pad-ink, the purpose of the present invention is to be to provide one kind can directly pass through to beat
In the aqueous polyurethane 3D polishes of textile surface prepares coating or 3D ink, it is strong that the coating of preparation has a third dimension to India side formula,
Glossiness is good, easily stacking, do not sink, soft, low temperature resistant, the advantages of firmness is good, solves existing pad-ink and exist
Ink diffusion, not blotting, problems of crack.
In order to realize above-mentioned technical purpose, the invention provides a kind of printable aqueous polyurethane 3D polishes or 3D ink,

Preferably scheme, mill base is Clariant aqueous color paste.
The concrete preparation technology of printable aqueous polyurethane 3D ink of the present invention comprises the following steps:
1st, after waterborne polyurethane resin being filtered, it is placed in high-speed stirred dispersion machine and is stirred, rotating speed is 300r/min,
Dispersion stirring 5min;
2nd, it is kept stirring for dispersion machine continuously stirred with 300r/min speed, add pH adjusting agent, deionized water and defoamer,
High-speed stirred dispersing speed is increased to 500~700r/min, dispersion stirring 5min;
3rd, maintain rotating speed constant, sequentially add wetting agent, drying retardant, levelling agent and coupling agent, after dispersion stirring 5min, slowly
Slowly add impermeable dose;
4th, after adding, high-speed stirred dispersing speed is increased to 800~1000r/min, adds bactericide, dispersion stirring
10min;
5th, after confirming to be uniformly dispersed, it is slowly added to thickener, after adding, dispersed with stirring rotating speed is increased to 1200~
1500r/min, disperses stirring 10~15min;
6th, after material dispersion is uniform, if making colored ink, high-speed stirred dispersing speed is reduced to 1000r/
Min, adds aqueous color paste, dispersion stirring 10min;
7th, after all materials are uniformly dispersed, drop to the slow-speed of revolution, stop stirring, filter, packaging, (if preparation 3D polishes, no
Operated with the 6th step).
Hinge structure, the Advantageous Effects that technical scheme is brought:The aqueous polyurethane 3D of the present invention
Polishes or 3D ink formulations it is critical only that employing a kind of special aqueous polyurethane is carrier, and this aqueous polyurethane film forming is hard
Spend relatively low (65A~75A), many experiments show into film hardness be higher than 75A or less than 65A aqueous polyurethane cannot meet will
Ask, using becoming aqueous polyurethane in the range of 65A~75A for the film hardness, have that flexibility is good, wear-resisting, adhesive force is good, water-fast
Wash, compatibility is good and other component between.On this basis, allocated suitable auxiliary agent into, such as wetting agent, drying retardant, impermeable
Agent, levelling agent, defoamer, thickener etc., each component synergy substantially, does not block up spray during making 3D polishes or 3D ink print
Mouth, and polishes or ink be difficult diffusion, absorbency good, do not ftracture.The coating third dimension of preparation is strong, and glossiness is good, easily stacks, no
It sink, soft, tortuous more than 150,000 times of normal temperature, low temperature resistant, subzero 15 DEG C of complications more than 80,000 times, dry and wet wipes color firmly 4
More than level, 60 DEG C of 5% buck washing 6h does not fall off, and does not fade, non-degradable.The ink of the present invention or polishes are adapted to various weavings
After product, the printing of footwear material requires.Additionally, the 3D polishes of the present invention or ink raw materials low cost, preparation method simple it is easy to industry
Metaplasia is produced.
