Description
Technical field
The present invention relates to textiles auxiliary agent field, relate in particular to a kind of high solid content amido silicone oil microemulsion and preparation method.
Background technology
Amido silicon oil has excellent adsorption, becomes the characteristics of mould and favorable orientation, can give fabric sofetening mild feel, improves the flexibility and the smooth property of fabric greatly, is the most popular soft finishing agent in textile auxiliary agent field in recent years.Amido silicon oil and methyl-silicone oil backbone structure are similar, molecular backbone chain is very submissive, it is a kind of bent volution linear chain structure of easily disturbing, alternately form by Siliciumatom and Sauerstoffatom, methyl is almost nil around the free energy of Si-O key rotation, very free, can 360 ° of rotations, this characteristic makes silicone oil become the best fabric softener, and amino can with the hydroxyl of fiber surface, interactions such as Suo Ji, be orientated very securely and be adsorbed on the fiber, form very firm film at fiber surface, the static friction coefficient of fiber is descended, just can make with very little power to begin between the fiber to slide, make fabric produce good soft and smooth property, so amido silicon oil have better effect than the silicone oil of other kind.Chinese market year needs about 400,000 tons of textiles soft finishing agent at present, and wherein the consumption of amido silicon oil soft finishing agent has surpassed 20,000 tons.
Amido silicon oil is many to be used with emulsion state, the high viscosity of amido silicon oil and low surface tension have determined its more difficult emulsification, particle size of emulsion and distribution thereof have bigger influence to the result of use of amino silicon oil emulsion, when amido silicon oil uses with the microemulsion state, the moulding property of fiber, the film density, performances such as pliability all are greatly improved, therefore microemulsion can effectively improve the use properties of amido silicon oil, and the many solid contents of amido silicone oil microemulsion that oneself prepare on the Chinese market are lower, bring a lot of inconvenience for storage and transportation, higher solids content and stable amido silicone oil microemulsion have abroad been arranged, but the amido silicone oil microemulsion of import often mixes emulsifying agent and other additives, makes that cost is higher and it is inconvenient to use.
Summary of the invention
The invention provides a kind of simple to operate, lower-cost high solid content amido silicone oil microemulsion and preparation method.
A kind of high solid content amido silicone oil microemulsion, weight percent consists of:
Amido silicon oil 1%～60%
Emulsifying agent 5%～19%
Assistant for emulsifying agent 2.5%～10%
Ionogen 0.01%～0.1%
Water 15%～90%
Described amido silicon oil viscosity is 50mPas～5000mPas, and the ammonia value is 0.1～1.5.
Described amino silicon monomer is N-β-aminoethyl-γ-aminopropyl methyl dimethoxysilane or γ-divinyl triammonium propyl group methyl dimethoxysilane.
Described emulsifying agent is that nonionic emulsifier is composite, is nonyl phenol oxyethylene ether and Fatty Alcohol(C12-C14 and C12-C18) oxyethylene ether, and the hydrophile-lipophile balance value (HLB) of the emulsifying agent after composite is 12.0～13.8.
Described assistant for emulsifying agent is a carbonatoms less than 6 low mass molecule alcohol and/or carbonatoms less than 6 low molecular acid.When low mass molecule alcohol and low molecular acid mixing use can be arbitrary proportion.
Described low mass molecule alcohol can be at least a in ethanol, propyl alcohol, propyl carbinol, Pentyl alcohol or the polyoxyethylene glycol, and described low molecular acid can be at least a in acetate or the oxalic acid.
Described ionogen is an an alkali metal salt, as: Repone K, sodium-chlor, Sodium Nitrite, potassium nitrite, saltpetre, sodium sulfate etc.
The preparation method of described high solid content amido silicone oil microemulsion may further comprise the steps:
Add amido silicon oil and emulsifying agent in the reactor, stir 40～60min, add assistant for emulsifying agent (alcohol, organic acid) and water then, continue to stir 40～60min, add ionogen and water, stir 40～60min and obtain high solid content amido silicone oil microemulsion.
The strong stirring rake of shearing of the employing of described stirring, mixing speed is 50r/min～2000r/min.
The temperature that described preparation method suits is 5 ℃～80 ℃, when winter temperature is low, needs suitably heating.
Described preparation method is anti-phase (anti-phase) emulsion process, at first mix by emulsifying agent and silicone oil, then by add assistant for emulsifying agent, power and water is separated the emulsion that matter is prepared the co-continuous phase structure between O/W and W/O, becomes the amido silicone oil microemulsion of O/W during use by dilution.
The high viscosity of amido silicon oil and low surface tension have determined its more difficult emulsification, the many solid contents of amino silicon oil emulsion on the domestic market are not high now, be below 40%, what adopt is that the emulsion polymerization solid content is high or adopt the positive emulsion process to cause particle diameter bigger more, and particle size of emulsion and distribution thereof have bigger influence to the result of use of amino silicon oil emulsion, particle diameter is more little, and performances such as the moulding property of fiber, film density, pliability can be greatly improved.The present invention adopts the anti-phase emulsion process to prepare the high solids content microemulsion of (surpassing 70%), and particle diameter greatly reduces the transportation and the storage cost of amino silicon oil emulsion below 100nm, and smaller particle size has improved its use properties.
The amido silicone oil microemulsion of the inventive method preparation is a doubly-linked ideotype structure, has after the dilution that particle diameter is little, narrowly distributing, solid content can reach higherly, are 20%～80% (w/w).And preparation process is simple, process is easy to control.
