Abstract

The invention discloses hydrophilic block polyether amino silicone oil with an amino branched chain and a preparation method thereof. The hydrophilic block polyether amino silicone oil with the amino branched chain has the following structure as shown in the specification, wherein R1 is represented by formulas shown in the specification. The preparation method comprises the following steps: carrying out mixing reaction of tetramethyl dihydro disiloxane, polysiloxane and concentrated sulfuric acid, neutralizing with anhydrous sodium carbonate, carrying out reduced pressure pumping to remove a low-boiling-point substance, and thus obtaining silicone oil with the end containing hydrogen; carrying out mixing reaction of the silicone oil with the end containing hydrogen, allyl epoxy polyether and a catalyst, and thus obtaining epoxy silicone oil; carrying out mixing reaction of the epoxy silicone oil, polyether amine and a solvent, and thus obtaining block polyether amino silicone oil; and carrying out mixing reaction of the block polyether amino silicone oil, a silane coupling agent hydrolysate and an alkali catalyst, neutralizing with glacial acetic acid, and thus obtaining the hydrophilic polyether amino silicone oil with the amino branched chain.

Description

technical field [0001] The invention relates to a hydrophilic block polyether amino silicone oil with amino branch and a preparation method thereof, which is suitable for textiles and fabrics as a treatment agent. Background technique [0002] Because some fibers contain many hydroxyl groups, there are strong intermolecular forces and hydrogen bonds between the fiber molecular chains, and the fabric has a certain strength and rigidity. To make the fabric soft, the force between fiber molecules should be reduced so that the molecular segments can move. The main chain of polysiloxane silicone softener is a helical straight chain structure that is easy to bend and is very soft. Through the cross-linking between the fibers and the polysiloxane forming a highly polymerized elastic network structure on the surface and inside of the fibers, the static friction coefficient between the fibers is reduced, and the fibers can slide with only a small force. Leaves the hand feeling soft...
