A kind of preparation method of quaternised modified amino-silicone oil softener and application
Technical field:
Preparation method and application the invention discloses a kind of quaternised modified amino-silicone oil softener, belong to weaving chemical industry
Technical field.
Background technology:
The synthesis of organosilicon quaternary ammonium salt can have a variety of methods, wherein more common have epoxy radicals silicone hydride and tertiary amine
Addition reaction, the substitution reaction of halocarbon base silane and tertiary amine, the quaterisation of amino silane and amino silane and epoxidation
The ring-opening reaction of compound.On the quaternised modified of amido silicon oil, research both at home and abroad shows:Select different quaternizing agents with
Amino reaction in amido silicon oil (silane), obtains the silicone oil containing different quaternary ammonium groups.Its quaternary ammonium salt-modified amido silicon oil
Synthetic method mainly has following direction:
Amido silicon oil is reacted with halide:There are the polysiloxanes and halohydrocarbons reaction of tertiary amine, obtain season by salt modified amido
Silicone oil.With N, N- diethyl-aminopropyltriethoxy dimethoxysilane and D4For raw material, tertiary amine groups silicon is prepared by hydrolysising balance
Oil, then using benzyl chloride be season by change tube- nursery polysiloxanes season press salt synthetic route, reaction process is simple, and condition is easily-controllable
System, it is not necessary to which excessive complicated processing can obtain the higher organosilicon quaternary ammonium salt of purity, and can control macromolecular well
The content products therefrom of function base has excellent bacteria resistance in chain.
Amido silicon oil is reacted with cationic etherifying agent:With α, alpha, omega-dihydroxy polydimethyl siloxane (WS-62M), N- β-ammonia
Ethyl-γ-aminopropyltrimethoxysilane (SG-Si900) and 3- chloro-2-hydroxypropyl-trimethyl ammonium chlorides are raw material, synthesis
Polysiloxane quaternary ammonium antibacterial and softening agent, the fabric after which arranges have good antibiotic property and washable
Property, and the feel of soft fabric and higher whiteness can be assigned.
Reacted with glycidyl quarternary ammonium salt compound:2,3- epoxypropyltrimethylchloride chlorides are-kind of end group is epoxy group
Quarternary ammonium salt compound, using the activity of epoxy group, open loop can be easily carried out with amino and be connected.What is obtained at the same time changes
Property silicone oil has low-yellowing performance, good feel, excellent hydrophilicity and fixed fixing property.By 2,3- epoxies third
Base trimethyl ammonia chloride presses quaternized modified reactive amino silicone oil, keep feel it is basic quite on the premise of, more can be with
Fabric is set to obtain very big raising in terms of whiteness and hydrophilicity.
Prepared through dimethyl suflfate quaterisation:Under the conditions of 100 DEG C, amidatioon is carried out to N-602 with methyl oleate,
It is quaternized through dimethyl suflfate again, organosilicone quaternary ammonium salt antibacterial finishing agent is prepared for, being arranged for cotton has certain antibacterial
Effect and washability.
Organosilicon quaternary ammonium salt is the polysiloxanes high-molecular compound with positive electricity, because of the dimethyl in polysiloxane macromonomer
Chain link and silica bond energy are rotated freely around macromolecular silica silicon chain, so the fabric after collated is very soft, quaternary ammonium salt is sun
Ionic, to negatively charged fiber, fabric has very strong adsorptivity, can efficiently precipitate and adsorb on fiber.Even if
Under conditions of low dosage, the electrostatic and interfibrous friction, quaternary ammonium salt group that can also be effectively reduced microfibre increase, whole
Hydrophilic antistatic property enhancing after reason, antibacterial fabric enhancing are nontoxic to Advanced Life body.Organosilicon quaternary ammonium salt has sterilization, suppression
Bacterium ability, is firmly combined with good anti-bacterial effect, nonhazardous, the arrangement available for underwear, sheet and operation textile with fiber.
Amido silicon oil has two kinds of amino, and the yellowing under conditions of high temperature bakes of the fabric after its arrangement is serious, this master
Will the reason for be that primary amine groups are easily aoxidized under light, heat effect in molecule, while on Y location secondary amine have collaboration accelerate primary
The effect of amido oxidation, promotes to form chromophore, causes finish fabric yellowing.Another major defect existing for amido silicon oil is
Hydrophily is poor, this molecular arrangement with its molecule on fabric fibre has a very big relation, the amino on amido silicon oil strand
Every fastness of the amido silicon oil to fabric can be increased, the performance of softness is also improved, simultaneously because a large amount of hydrophobic methyls
Presence, it is difficult to be in contact with fiber to make hydrone, due to hydrophobicity strengthen, electrically charged higher, the fabric table under drying regime
It is very uncomfortable up to 1000-50O0V, dress that face senses electrostatic pressure.
In December, 2010 Donghua University's Textile Chemistry and Dyeing and Finishing Engineering Di Chao disclose one it is entitled《Quaternised modified amino
The synthesis and application of silicone oil softener》Master's thesis, by using glycidyl dodecyl dimethyl ammonium chloride to common
Amido silicon oil progress is quaternised modified, has synthesized quaternized modified amino silicone oil softener, has been introduced on amido silicon oil hydrophilic
After quaternary ammonium salt group, the more preferable hydrophily of fabric can be assigned, and drop while reservation amido silicon oil original excellent handle
Its low yellowing phenomenon in high-temperature process.The document is using octamethylcy-clotetrasiloxane (D4) as monomer, aminoethyl ammonia third
Ylmethyl dimethoxysilane is coupling agent, hexamethyldisiloxane be end-capping reagent, tetramethylammonium hydroxide as catalyst, into
Row bulk copolymerization reacts, and amido silicon oil is prepared, by adjusting the dosage of coupling agent and end-capping reagent, can obtain different ammonia values
With the product of viscosity.With N, mono- dimethyl lauryl amines of N and epoxychloropropane are Material synthesis glycidyl dodecyl dimethyl
Ammonium chloride, epoxide number 0.28mol/100g, its conversion ratio are 96%.By amido silicon oil and quaternised modified amino-silicone oil lotion
Soft finish is carried out on pure cotton fabric, measures and compared for being organized the whiteness of fabric, is ultimate strength, tearing brute force, hydrophilic
Property and Fabric Style test in fabric bending, shearing, compression performance and surface friction property, the modified amino of the results show
Fabric yellowing phenomenon after silicone oil emulsion arranges substantially reduces, and hydrophily increases substantially, and maintains fabric excellent handle, and
And be substantially better than unmodified amido silicon oil in the aspect of performance such as elasticity and compression, be the present invention closest to the prior art, still
The technology preparation process is complicated, while the hydrophilicity whiteness influence on fabric after arrangement is still not ideal enough, and for influencing
The resisdye of fabric and Xiu Se produce certain adverse effect.
The content of the invention:
Technical problem solved by the invention:
In view of the deficiencies of the prior art, the present invention provides a kind of preparation method of quaternised modified amino-silicone oil softener,
And it is applied to during the final finishing of pure cotton fabric.Preparation method of the present invention is simple and easy to operate, and raw material is environmentally protective, technique
