Description
Technical field
The invention belongs to dye field, be specifically related to a kind of use for synthetic leather water dyeing auxiliary agent and preparation method thereof.
Background technology
China is the big producing country of leather industry in the world, the annual rate of increasing output value more than 7%, but the trueest
Skin industry market atrophy, country is increasingly tighter to environmental requirement, and the leather market shrink of Hebei Province is serious.So super fine synthesis
Remove from office owing to having the wearability of excellence, good tearing toughness, breathable moisture permeability close to corium gradually replace corium.But
Microfiber synthetic leather base fabric in the market is still made with resin based on the polyurethane resin of oiliness.Many institute's weeks
Know that oiliness polyurethane resin dyeability is poor.So develop a kind of environmental protection, dyeing assistant that dye uptake is high imperative.
Patent CN105401468A discloses a kind of dyeing polyester fibers auxiliary agent.The raw material of this disclosure of the invention is more complicated
And compounding form, its shelf-stability is poor, simultaneously containing protein substance in formula, causes its antiseptic property
Difference, has a strong impact on the shelf life of finished leather.
Patent CN105463881A discloses a kind of cloth dyeing assistant.The raw material of this disclosure of the invention contains formaldehyde, right
Produce and application workman endangers greatly.
Summary of the invention
For the above-mentioned technical problem existing for current dyeing assistant field, the invention provides a kind of use for synthetic leather aqueous
Dyeing assistant and preparation method thereof, is characterized in preparing the response time short, and technics comparing is simplified；The water dyeing auxiliary agent produced
Application effect embodies bright in colour natural, and rate of dyeing is high and does not affect leather surface feel；And the dyeing assistant of the present invention is the most toxic
Property raw material, environmental protection.
The use for synthetic leather water dyeing auxiliary agent of the present invention, is made up of the component of following mass fraction: deionized water 50-100
Part, initiator 0.15-0.2 part, cross-linking monomer 0.2-0.4 part, monobutyl itaconate 2-6 part, diisooctyl maleate 2-6 part,
2-Propenoic acid, 2-methyl-, isooctyl ester 10-15 part, isobornyl methacrylate 1-2 part, octadecyl methacrylate 0.08-0.2
Part, emulsifying agent 0.05-0.1 part, acrylic acid 0.4-0.6 part, pH adjusting agent 0.3-0.6 part.
Wherein, initiator is hydrogen peroxide；Cross-linking monomer is methacrylic acid acetoacetic acid diethylene glycol dilaurate or dimethyl
Acrylic acid glycol ester；Emulsifying agent is Dodecyl trimethyl ammonium chloride or Dodecyl trimethyl ammonium chloride；PH adjusting agent is
Dimethylethanolamine.
The preparation method of the use for synthetic leather water dyeing auxiliary agent of the present invention, comprises the following steps:
(1) polyreaction: under the protection of dry high purity nitrogen, successively by deionized water, emulsifying agent, cross-linking monomer, clothing
Health acid mono-n-butylester, diisooctyl maleate, octadecyl methacrylate, acrylic acid, 2-Propenoic acid, 2-methyl-, isooctyl ester, methyl-prop
Olefin(e) acid isobornyl thiocyanoacetate joins in reaction vessel, under mechanical stirring, is warming up to 80-85 DEG C, is added dropwise to initiator, reacts 0.5-
After 1.0h, it is heated to 88 DEG C of insulation 1.5-2h；
(2) after insulation, being cooled to 50-55 DEG C and add pH adjusting agent, adjusting pH is that 6.5-7.0 obtains use for synthetic leather water
Property dyeing assistant.
Use for synthetic leather water dyeing auxiliary agent of the present invention and preparation method thereof has the advantages that
(1) it is short to prepare the response time, and technics comparing is simplified.Be conducive to saving the energy, reducing production cost.Depositing of product
Cycle is long, the most perishable, can deposit up to 1 year；
(2) use Dodecyl trimethyl ammonium chloride or Dodecyl trimethyl ammonium chloride as emulsifying agent.This kind of surface
Activating agent has good emulsifying dispersivity, such that it is able to produce the emulsion that particle diameter is minimum, permeability is splendid.In application process
In easily infiltrate through leather surface, give leather surface and inhale color characteristic, so that the leather surface lovely luster after Ran Se；
(3) employing hydrogen peroxide is as initiator, owing to its initiating activity is moderate, polyreaction is easily-controllable so that be polymerized
Journey without residue, conversion rate of products is high, catabolite is harmless；
(4) methacrylic acid acetoacetic acid diethylene glycol dilaurate or Ethylene glycol dimethacrylate is used to replace N-methylol
Acrylamide is as cross-linking monomer so that the dyeing assistant produced does not contains formaldehyde, improves the safety that dyeing assistant uses
Property, meet the environmental requirement of country；
(5) extraordinary monomer itaconic acid mono-n-butylester, diisooctyl maleate, octadecyl methacrylate, methyl are used
Isooctyl acrylate monomer and isobornyl methacrylate improve the suppleness of dyeing assistant, color development effect and dye uptake.
