A kind of prescription of novel block hydrophilic silicone oil and synthesis techniqueTechnical field
The present invention relates to a kind of block hydrophilic silicone oil, especially a kind of prescription of novel block hydrophilic silicone oil and synthesis technique.
Background technology
All need to use amido silicon oil in the hand feel finishing agent of textiles in the market.Amido silicon oil is the modified silicon oil that grow up the eighties in last century a kind of is mainly used in softness, fluffy, smooth hand arrangement, but amido silicon oil can not directly use, must add and to use after emulsifying agent is emulsified into dairy industry, because amido silicon oil problems such as easy breakdown of emulsion, floating oil, generation silicone oil spot in the process of using.In addition, contain the chemical ingredientss such as formaldehyde, NP/APEO and heavy metal in the amido silicon oil, have higher contaminative.
In recent years, the block silicone oil of substituted-amino silicone oil product progressively came into vogue in market, but because synthetic operation more complicated, and the raw material dependence on import causes that block silicone oil quality on the market is unstable, cost is higher.
Summary of the invention
The objective of the invention is to provide for the deficiency that solves above-mentioned technology that a kind of low cost of manufacture, technique are simple, prescription and the synthesis technique of a kind of novel block hydrophilic silicone oil of environmental protection.
In order to achieve the above object, the prescription of a kind of novel block hydrophilic silicone oil that the present invention is designed, it comprises 35-45 part aliphatic poly ether diamine, 300-340 part Virahol, 360-400 part epoxy group(ing) end-blocking silicone oil, 4-6 part concentration is 20% sulphuric acid soln, 400-450 part dipropylene glycol, 150-170 part isomery polyoxyethylenated alcohol and 1-3 part Glacial acetic acid, above umber is calculated by weight.
As preferably, described aliphatic poly ether diamine is that 900 aliphatic poly ether diamine and molecular weight are that 2000 aliphatic poly ether diamine consists of by molecular weight, and the two quality equates.
Production technique: the first step, with 35-45 part aliphatic poly ether diamine, 300-340 part Virahol, 360-400 part epoxy group(ing) end-blocking silicone oil is put in the reactor together, is heated to 80 ℃, insulation reaction 8 hours; Second step, adding 4-6 part concentration are 20% sulphuric acid soln, balanced reaction 30 minutes; The 3rd step added 400-450 part dipropylene glycol, balanced reaction 30 minutes, and negative pressure vacuumizes, and is warming up to 100 ℃, and vacuum tightness is evacuated to the highest, takes out most volatile matter Virahol, and balanced reaction 30 minutes is cooled to 50 ℃; The 4th step added 150-170 part isomery polyoxyethylenated alcohol and 1-3 part Glacial acetic acid, stirred, and was cooled to 35 ℃, discharging.
Prescription and the synthesis technique of the resulting a kind of novel block hydrophilic silicone oil of the present invention, production technique is simple, the block hydrophilic silicone oil that manufactures is that the polynary block modified organosilicon of a kind of linearity is supported alkane, embed epoxy group(ing), polyethers and amino etc. on the molecular backbone chain, be exclusively used in terylene, nylon, nitrile, the blending of hair nitrile, blend polyester and put in order behind various loose hairs, yarn, fabric and the fabric such as textile soft; In addition, the environmental protection leavening agent that the present invention makes does not contain the chemical ingredientss such as formaldehyde, NP/APEO and heavy metal, very environmental protection.
