Description
Technical field
The present invention relates to a kind of textile auxiliary fields, more particularly, to a kind of blocked isocyanate self-cross linking type one-way wet-guide
Agent and preparation method thereof.
Background technique
The wet guilding of fabric is an important indicator for measuring clothes level of comfort.Fabric energy with good wet transmitting performance
The sweat that human body generates uniaxially is transmitted to the outer surface of fabric from the inner surface of fabric and is quickly spread, to keep human body skin
Skin is dry, adjusts the comfort in human body micro climate area.Recent domestic researcher be all mostly by change fibre structure and
Fabric structure realizes the one-way wet-guide of fabric.Although this fabric structure can be realized quick moisture absorption, unfavorable
In the rapid evaporation of moisture.Currently, being arranged using one-way wet-guide finishing agent to fabric, by the parent for changing fabric ectonexine
Hydrophobicity realizes the rapid evaporation of moisture.Common one-way wet-guide agent is fluorine-containing water repellent finishing agent, the finishing agent hydrophobicity
Can be excellent, but easily accumulated in nature and organism, harm finally is generated to the mankind, does not meet the requirement of environmental regulation.
Summary of the invention
Object of the present invention is to customer service the deficiencies in the prior art, provide a kind of wash fast sealing end for meeting environmental regulation requirement
Isocyanates self-cross linking type one-way wet-guide agent.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of blocked isocyanate self-cross linking type one-way wet-guide agent, is matched by weight:

Water glycerol propyl) 4~6 parts of -1,1,3,3- tetramethyl disiloxane, 10~15 parts of chain alkyl dimethyl silicone polymer, hydrogen-oxygen
Change 0.5~1 part of potassium, 0.6~2 part of methyl ethyl ketoxime, 1.5~3 parts of diethylenetriamine.
A kind of preparation method of blocked isocyanate self-cross linking type one-way wet-guide agent, including following synthetic method and step:
By octamethylcy-clotetrasiloxane, 3- isocyanate group propyl-triethoxysilicane, (the 3- glycidol third of 1,3- bis-
Base) -1,1,3,3- tetramethyl disiloxane, chain alkyl dimethyl silicone polymer and potassium hydroxide are added in reaction vessel,
100~120 DEG C are heated to, after keeping the temperature 3~4h, then is cooled to 70~80 DEG C, methyl ethyl ketoxime is added dropwise, is added dropwise to complete rear insulation reaction
0.5~1h adds diethylenetriamine, and cooling discharge after 0.5~1h is kept the temperature at 70~80 DEG C, obtains blocked isocyanate certainly
Cross-linking type one-way wet-guide agent.
Preferably, the molecular weight of the chain alkyl dimethyl silicone polymer is one in 8000,10000,12000
Kind.
Preferably, the one-way wet-guide agent is applied to nylon fabric.
The present invention uses 3- isocyanate group propyl-triethoxysilicane for self-cross linking monomer, is sealed using methyl ethyl ketoxime
End, when high-temperature process, unseal, and are formed and are crosslinked with active hydrogen reactions such as amino, hydroxyls in system, improve fabric after arrangement
The washing fastness of one-way wet-guide performance and smooth performance；The introducing of long chain alkane PolydimethylsiloxaneChain Chain section, provides for system
Good hydrophobicity, and assign fabric preferable soft and smooth performance；It uses diethylenetriamine for chain extender, increases finishing agent
While to the adsorptivity of fiber, and the isocyanate group that can be honored as a queen with solution reacts, and achievees the purpose that self-crosslinking.It reacted
It not being needed in journey using solvent, no fluorochemical monomer participates in, the discharge of volatile organic compounds (VOC) in use process is reduced,
Avoid the generation of perfluorooctanoic acid salt (PFOA), perfluorooctane sulfonyl compound (PFOS), safety and environmental protection.
