Abstract

The invention provides a microwave preparation method of a smooth type quaternization block organosilicon polymer. The microwave preparation method comprises the following steps of (1) adding allyl epoxy polyether and silicone oil into a reactor, uniformly mixing, radiating by microwaves at the power of 50 to 600W, leading nitrogen, heating to 80 to 100 DEG C, adding a platinum catalyst, and warming for 30 to 60min, so as to obtain terminated epoxy silicone oil; (2) adding the obtained terminated epoxy silicone oil in step (1), polyether amine and an organic solvent into the reactor, uniformlymixing, radiating by microwaves at the power of 50 to 600W, leading nitrogen, heating to 70 to 85 DEG C, and warming for 1 to 5h, so as to obtain a block organosilicon intermediate A; (3) adding an chain extender into the step (2), reacting for 15 to 90min at the temperature of 70 to 85 DEG C, enabling the block organosilicon intermediate A to continue to extend chain, and using glacial acetic acid to adjust the pH (potential of hydrogen) value of the system to neutral property, so as to obtain the smooth type quaternization block organosilicon polymer.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, more specifically, the invention relates to a microwave preparation method of smooth quaternized ammonium block organosilicon polymers. Background technique [0002] Silicone polymer is a kind of man-made polymer. Due to its structural characteristics, silicone products have the characteristics of both inorganic and organic substances, and have excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological properties and small High surface tension, low viscosity-temperature coefficient, high compression resistance and radiation resistance. Organosilicon polymers are a type of polymer with a repeating segment of Si-O-Si as the main chain, and some silicon atoms are connected with organic groups, also known as polysiloxane. Silicone polymers with Si-O-Si as the skeleton structure and methyl side chains can be formed by simple hydrolysis of the ...
