Description
Technical field
The present invention relates to paint field, especially a kind of environment-friendly type coating dyeing adhesive and preparation method thereof.
Background technique
Pigment dyeing is divided into exhaust dyeing with pigment and Pigment Padding, and exhaust dyeing with pigment is fabric after cation modifier is handled,
Make its surface with positive charge, negatively charged granules of pigments passes through electrostatic force and Van der Waals force in conjunction with fiber in dye liquor,
And Covalent bonding together occurs with the active group on modified fiber, under the action of adhesive is added, pigment is in conjunction with fiber
It is stronger, not only color fastness is excellent, and feel is also unaffected.Pigment Padding refers to pigment, adhesive dispersing agent etc. first
Other auxiliary agents dissolve in water, disperse to be tuned into coating dye liquor, and fabric is put into the coating dye liquor, passes through padding machine after a period of time
Apply certain pressure and removes extra dye liquor, so that webbing liquid is uniform, then evaporates moisture by drying and completes fixation,
Granules of pigments is adhered to fabric surface by adhesive package, forms one layer of reticular membrane with stereochemical structure.Pigment dyeing has
Following advantages: due to its mainly by adhesive pull-out capacity colour, to contaminate fiber does not have any selectivity, be suitable for
The dyeing of various fibers；Competing dye problem is not present when pigment color-matching, is easy to colorant match, repeatability is good；Pigment dyeing chromatography is complete, resistance to
Light, good weatherability；Dyeing process is shorter, energy saving, and sewage quantity is few.
Since there is no affinity to fiber for coating itself, relies primarily on adhesive and adhered to fabric surface.Therefore,
The type and property of adhesive have been largely fixed the final effect of pigment dyeing.Pigment dyeing type adhesive needs to have
Following performance: film colorless and transparent, that adhesion strength is strong can be formed on the fabric；It is not easy yellowing, it is ageing-resistant；The film of formation has resistance to scratch
Bent, resistance to wrinkle do not harden, do not adsorb coloring matter, not tacky and good elastic property；Nontoxicity has good storage
Stability；There are conjunctiva speed appropriate and preferable rheological characteristic.Pigment dyeing adhesive can be divided into three classes, solvent type
Adhesive, water-dispersion type adhesive and Emulsion Adhesive, wherein Emulsion Adhesive is to be somebody's turn to do at present using more type
Class adhesive is prepared using emulsion polymerisation process, has good chemical stability, storage stability and mechanical stability.
Chinese patent CN201210442862.0 discloses a kind of pigment dyeing binding agent and preparation method thereof.With parts by weight
Meter, the invention are composed of the following components: ethylenediamine carbamate: 10-20, acrylic acid: 1-3, vinyl acetate: 3-6, methyl
Methyl acrylate: 10-16, dibutyl phthalate: 3-5, neopelex: 1-3, sodium oxalate: 1-3, water: 60-
80.Compared with prior art, which has the following beneficial effects: that (1) viscosity is appropriate, and storage stability is good, with other auxiliary agents
Compatibility it is good, it is nontoxic, non-stimulated；(2) film forming speed is moderate, no roll banding or skinning；(3) what is formed on the textile is thin
Film is colorless and transparent, and wear-resisting and adhesion strength is strong.
Summary of the invention
The present invention relates to a kind of environment-friendly type coatings to dye adhesive, which has good caking property
Can, stable transparent membrane can be formed in fabric surface, so that fabric has stronger color fastness.Also, the adhesive is not
Containing organic solvent, injury will not be brought to human health, it is environmentally protective.
