Description
Technical field
The present invention relates to a kind of synthetic method of modified silicon oil, be specially terpolymer block silicone oil synthetic method.
Background technology
At present, be widely used in the back arrangement processing of textiless such as cotton, silk, wool and terylene based on the softening agent of various amino-modified silicone oil emulsions, the fabric of arrangement has softness, performance smooth, attractive in appearance, washable and comfortable and easy to wear.This series products is accepted by people.Weak point shows that mainly the fabric through its arrangement is hydrophobicity, feels sultry when wearing and is difficult to washing; With the light color and the white fabrics of its arrangement, after baking through high temperature, xanthochromia phenomenon in various degree can appear, and much the amino-modified silicone emulsions is stable very poor, occurs " breakdown of emulsion floating oil " phenomenon in be everlasting accumulating and the application process; In padding use, there is the roll banding phenomenon to produce.
In order to overcome the above-mentioned shortcoming of traditional amido silicon oil, people adopt the whole bag of tricks to improve, and have side chain polyether-modified, also have epoxide modifiedly or carboxy-modified, and silicone oil after modification stability improves, but the feel deviation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of terpolymer block silicone oil synthetic method, the prepared terpolymer block of this method silicone oil.
Technical scheme of the present invention: for solving the problems of the technologies described above, terpolymer block silicone oil synthetic method of the present invention in turn includes the following steps, and each composition consumption calculates with mass parts:
A, in reaction vessel, add 100 parts of dimethyl cyclosiloxane or octamethylcyclotetrasiloxane, the agent of 4 parts of end ring oxygen double-seal heads, 15 parts of N,N-DIMETHYLACETAMIDEs, be warming up to 70-80 ℃, add 0.02-0.1 part alkaline catalysts, be warming up to 110-120 ℃ again, reaction 3-4h slowly opens vacuum then, extract solvent and low molecular weight substance out, and keep being warming up to 140-145 ℃, insulation also keeps vacuum 2h, obtains end ring oxygen silicone oil;
B, in reaction vessel, add the prepared end epoxy group(ing) of steps A silicone oil 80-100 part, polyether glycol 6-30 part, 150 parts of Virahols carry out back flow reaction 6-15h under 8O-86 ℃, decompression at last removes Virahol or adds the propylene glycol replacement solvent, obtains amino-polyether block silicone oil.
Further, alkaline catalysts described in the steps A is a potassium hydroxide.
Further, the described polyether glycol of step B is made up of 2-10 part polyether glycol 203,2-10 part polyether glycol 206 and 2-10 part polyether glycol 209.
Further, the end ring oxygen double-seal head agent described in the steps A is prepared by following substances, and each material consumption calculates with mass parts:
Tetramethyl-dihydro base sily oxide, 42 parts of glycidyl allyl ethers, 100 parts of N,N-DIMETHYLACETAMIDEs of in withstand voltage reactor, adding 35 parts of hydrogeneous double-seal heads, stir, add 1 part of 1%(quality) the Platinic chloride ethanolic soln, capping still then, be warming up to 90-95 ℃ of reaction 7-8h, at last with the reactant underpressure distillation, remove desolvate the agent of end ring oxygen double-seal head.
Ternary block copolymerization silicone oil of the present invention not only has high temperatures, no breakdown of emulsion demixing phenomenon, advantages such as self-emulsifying characteristic, and owing in siloxane backbone, carry out amino and the copolymerization of polyether-based linearity block, synthetic new linear amino-polyether group block copolymer, be that ternary block copolymerization silicone oil is because amino anchorage effect, make whole polysiloxane energy mortise at fabric face, kept the original flexible smooth of polysiloxane, hydrophilic polyether segment then is present in fiber surface to fall the form of shape, water molecules is in the uncrossed transmission of fiber surface, form soft and hydrophilic compatibility, this is a new stage of silicone softening agent development, also is the development in future direction.The smooth feeling of general ternary block copolymerization silicone oil is all fine, and that fluffy sense is carried out is just not too easy, and institute of the present invention synthetic end ring oxygen silicone oil intermediate can bring very big adjusting leeway to later reaction, has guaranteed fluffy sense.Relating to following two aspects in the technological process of the present invention regulates: one, regulate synthetic end ring oxygen silicone oil molecular weight size; Two, regulate polyethers kind and consumption, thereby adjust the feel skewed popularity of fabric.Generally speaking, fabric uses the good hand touch behind the ternary block copolymerization silicone oil of the present invention, promptly fluffy sense, and smooth feeling, fabric do not have xanthochromia or low-yellowing.
