Abstract
The present invention relates to a making method for water-base polyurethane dye used for paint, fabrics, leatherette and leather. By adopting grafting reaction technology, dye precursors (such as alcohol dye and amine dye) comprising active hydrogen are reacted with isocyanate, and are grafted onto molecular chains of polyurethane. Then, by the method of chain extension, crosslinking, side hanging of active groups, leading of hydrophilic agents, crosslinking points, active groups and hydrophilic groups are led in polyurethane chains; when the molecular weight is large enough, the polyurethane is neutralized, emulsionized and treated through exsolution to obtain self-solidification type water-base polyurethane dye. The product produced by the present invention has the advantages of favorable dye fastness, vivid and saturated color, easy use, low cost and no toxicity or pollution.
Description
Technical field
The present invention relates to the manufacture method of aqueous polyurethane dye, specifically be used for the manufacture method of the aqueous polyurethane dye of coating, fabric, leatheroid, leather.
Background technology
Dyestuff is can make fiber (natural fiber is as cotton, fiber crops, wool, silk etc.; Regenerated fiber, as terylene, acrylic, polypropylene fibre, polyvinyl etc.) and other be colored the class Chemicals that material (paper, timber, leather, sensitive materials, food, medicine, makeup, printing ink, coating, plastics, rubber etc.) obtains distinct and strong color, its range of application relates to all respects of people's lives.Along with people are more and more higher also along with the reinforcement of environmental protection dynamics to the requirement of dyestuff over-all properties, some supersensitivity dyestuffs, the high dyestuff of toxicity, contain Environmental Hormone dyestuff, the heavy metal content dyestuff etc. that exceeds standard and banned use of gradually, there is small molecules organic dye volatilization in organic dye and to environmental hazard, macromole dyestuff such as patent DT2930738; The clear 56-53292 of Ri Tekai, the clear 56-128382 of Ri Tekai, the clear 54-64186 of Ri Tekai; USP 4,182,855, USP4, and 258,189, USP 5,700,851, and USP 6,524, and there be the influence of organic solvent evaporates to environment for human survival in the polymeric dye described in 978.Therefore each DYE PRODUCTION big country is is all researching and developing high-performance dyestuff and various environmental protection type dye energetically in recent years.
Since British Bai Qin in 1857 synthesized mauvein (e) first, the kind of synthetic dyestuff had reached kind more than 7000,800,000 tons of annual production.But be mostly organic dye, because of the organic dye contaminate environment, performance such as color fixation fastness, water tolerance is undesirable, abroad begin polymeric dye is studied and produced latter stage from the eighties, much more existing on synthetic method what adopt is (1) reaction fixation type polymeric dye, the Indosal dyestuff of producing as the Shandeshi company of Switzerland.It can combine with active laking agent, can combine with Mierocrystalline cellulose again, thereby dyefastness is improved; (2) from fixation type polymeric dye, as the Reactint reactive dye of Mei Liken chemical company production.It is that dye matrix is grafted on the polymkeric substance, thereby combines dyestuff and polymer properties, and the dyeing behavior of dyestuff is improved.The research work of polymeric dye at present mainly concentrates on from fixation type polymeric dye aspect.
