Amino silicone oil softener has excellent softness, smoothness and film forming advantages, is widely used in all kinds of textile finishing, the following we jinan multi-dimensional bridge chemical company studied the synthesis method of amino silicone oil and its microemulsification process. 

  1. Amino silicone oil microemulsion is used for soft finishing of fabric and has good use effect.

  2. The optimal process conditions are as follows: reaction temperature 135 ~ 145℃, reaction time 4 ~ 5 hours, catalyst dosage 0.06 ~ 0.08%. 

  3, the ratio of compound emulsifier is 60% fatty alcohol polyoxyethylene ether, 40% alkyl phenol polyoxyethylene ether.The dosage is 43% of the mass of amino silicone oil.

  4. Adding a small amount of organic acid ester (NZ) and sodium bisulfite (NS) into the microemulsion can effectively reduce yellowing, without increasing the cost and reducing the softness. 

  5. Using octmethylcyclotetrasiloxane (D4) and N-β -aminoethyl -γ -aminopropyl methyl dimethoxy siloxane (N602) as raw material, potassium hydroxide (KOH) as catalyst, different ammonia value and different viscosity of amino silicone oil can be synthesized by bulk polymerization.

  6, the compound emulsifier with fatty alcohol polyoxyethylene ether (ne0-9) and nonylphenol polyoxyethylene ether (TX -- 4) can emulsify amino silicone oil into transparent and clear microemulsion, the particle size is less than 0.15μm(150nm). 

  7. The emulsification process of amino silicone oil into microemulsion is as follows: the amino silicone oil and compound emulsifier are stirred and mixed in conventional equipment, the stirrer speed is 80 ~ 100r/min, and the good stability of amino silicone oil microemulsion can be obtained by stirring and mixing at room temperature for 30 minutes without high speed and high shear equipment or homogenizer.

  Fatty alcohol polyoxyethylene ether (AEO), also known as polyoxyethylene fatty alcohol ether.Non-ionic surfactants in the development of Z fast, Z large dosage of varieties.This type of surfactant is made of polyethylene glycol (PEG) and fatty alcohol condensation ether, with the following general formula: RO (CH2CH2O) nH, where n is the degree of polymerization, because of the degree of polymerization of polyethylene glycol and different types of fatty alcohol and there are different varieties.The trade name is benzyl benzyl (Brij), such as Brij30 and Brij is made of different numbers of polyethylene glycol and lauric acid condensation, can be used as O/W type emulsifier.
