CN105111447A - Novel water-soluble amino silicone oil and preparation method thereof - Google Patents

Abstract

The invention provides novel water-soluble amino silicone oil and a preparation method thereof. The novel water-soluble amino silicone oil is characterized by comprising, by mass, 30-40% of octamethylcyclotetrasiloxane, 10-14% of coupling agent, 15-20% of tetramethyl ammonium hydroxide, 5-15% of end blocking agent, 4-9% of epoxy polyether, 3-9% of glacial acetic acid and 5-9% of isopropanol. Epoxy polyether is grafted on self-prepared amino silicone oil to synthesize hydrophilic amino silicone oil which can be directly dispersed in water without emulsification, and the novel water-soluble amino silicone oil does not occur demulsification and oil floating during use and does not form oil spots on fabric. Tetramethyl ammonium hydroxide which is used is a chelate, and is high in compatibility with octamethylcyclotetrasiloxane, low in reaction temperature, easy to control and decomposable at high temperature, so that tetramethyl ammonium hydroxide does not be left in the amino silicone oil.

Description

A kind of new type water-solubility amido silicon oil and preparation method thereof

Technical field

The present invention relates to chemical field, particularly relate to a kind of new type water-solubility amido silicon oil and preparation method thereof.

Background technology

Amino silicone oiland emulsion is widely used in textile industry, major part is used as the flexible smooth finishing composition of various fiber and fabric.But because fabric processing is carried out in aqueous systems, therefore for the amido silicon oil of its coupling is also mainly with emulsion form use, therefore amido silicon oil must be used before the use emulsificationagent emulsification, the emulsifying agent usually adopted has fatty alcohol-polyoxyethylene ether etc., and solubilizing agent has ethylene glycol monobutyl ether, ethylene glycol monomethyl ether, diethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether etc.In addition, amino silicon oil emulsion in use, due to emulsification and the impact of other factors, there will be breakdown of emulsion and floating oil phenomenon, the silicone oil after breakdown of emulsion adheres on fabric can form oil mark, has influence on the visual appearance of fabric, on the other hand, fabric after amido silicon oil process, its wetting ability can decline, and has influence on fabric (especially dead cotton fabric) snugness of fit.

Summary of the invention

According to above technical problem, the invention provides a kind of new type water-solubility amido silicon oil and preparation method thereof, its feature is comprising octamethylcyclotetrasiloxane, coupling agent, Tetramethylammonium hydroxide, closure agent, epoxidized polyether, Glacial acetic acid, Virahol, and its concrete mass percent is: octamethylcyclotetrasiloxane 30%-40%, coupling agent 10%-14%, Tetramethylammonium hydroxide 15%-20%, closure agent 5%-15%, epoxidized polyether 4%-9%, Glacial acetic acid 3%-9%, Virahol 5%-9%.

A kind of new type water-solubility amido silicon oil preparation method, its concrete operation step is:

First choose according to aforementioned proportion and prepare material, then octamethylcyclotetrasiloxane, coupling agent, closure agent are added in four-hole boiling flask, again heated and stirred is carried out to four-hole boiling flask, stop heating when temperature rises to 90 DEG C, be incubated 2 hours, then add catalyzer Tetramethylammonium hydroxide, be warming up to (105 ± 2) DEG C stopping to heat, insulation reaction 4 hours, is warming up to 140 DEG C after above reaction completes, and vacuumizes decomposition catalyst 30 minutes.

Beneficial effect of the present invention is: the present invention adopts epoxidized polyether to be grafted on homemade amido silicon oil, synthesize a kind of hydrophilic amido silicon oil, this silicone oil need not emulsification can directly be scattered in water, in use there will not be breakdown of emulsion and floating oil phenomenon, more can not form oil mark on fabric.The Tetramethylammonium hydroxide of the present invention's application is an inner complex, and better with octamethylcyclotetrasiloxane consistency, temperature of reaction is lower, easily controls, and it at high temperature can decompose, and therefore can not remain in amido silicon oil.Amido silicon oil of the present invention due to molecular backbone chain submissive, Intermolecular Forces is little, so surface tension is low, two amino polarity is wherein strong, by the interaction of the hydroxyl, carboxyl etc. of fiber surface, orientation and being adsorbed on fiber very securely, thus reduce interfibrous frictional coefficient, gives fabric and surpasses soft effect and good smoothness and washing fastness; And epoxidized polyether inherently has good hydrophilicity, be grafted to by epoxidized polyether on amido silicon oil, the present invention combines both advantage, and the cotton fabric processed during use has soft feel and has again good wetting ability, fabric does not produce electrostatic, obtains good wear behavior.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

According to Fig. 1, the present invention is further described:

First choose and prepare material, according to mass percent be: octamethylcyclotetrasiloxane 35%, coupling agent 12%, Tetramethylammonium hydroxide 18%, closure agent 13%, epoxidized polyether 8%, Glacial acetic acid 8%, Virahol 6%; Then octamethylcyclotetrasiloxane, coupling agent, closure agent are added in four-hole boiling flask, again heated and stirred is carried out to four-hole boiling flask, heating is stopped when temperature rises to 90 DEG C, be incubated 2 hours, then add catalyzer Tetramethylammonium hydroxide, be warming up to (105 ± 2) DEG C stopping and heat, insulation reaction 4 hours, after above reaction completes, be warming up to 140 DEG C, vacuumize decomposition catalyst 30 minutes.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
