preparation example Construction

[0032] The preparation method step of cationic amino silicone oil microemulsion is as follows:

[0033] a) Pre-emulsification of organosiloxane monomer, cationic emulsifier, and nonionic emulsifier into pre-emulsion I;

[0034] b) Put water, cationic emulsifier, non-ionic emulsifier in the reactor and heat to 60~90 ℃, then add catalyst; Get 50% pre-emulsion I dropwise from the pre-emulsion I generated in step a) Inside the reactor;

[0035] c) adding a silane coupling agent, a cationic emulsifier, and a nonionic emulsifier to the remaining 50% of the pre-emulsion I generated in step a) to pre-emulsify into a pre-emulsion II;

[0036] d) After the addition of the pre-emulsion I in step b) is completed, add the pre-emulsion II dropwise into the reactor; the total time of adding the pre-emulsion I and pre-emulsion II is less than or wait for 4 hours.

[0037] e) After the heat preservation reaction for 6-12 hours, the temperature is lowered to room temperature, and a neutralizi...

Abstract

The invention discloses a cation amino silicone oil micro-emulsion and a preparation method thereof. The cation amino silicone oil micro-emulsion is prepared from the following components in percentage by weight: 5-30% of organo-siloxane monomer, 0.1-0.5% silane coupling agent, 3-10% of cationic emulsifier, 2-8% of nonionic emulsifier, 0.1-0.5% of basic catalyst and the balance of water, and the total weight percentage of all the components is 100%. The particle size of the cation amino silicone oil micro-emulsion prepared by using the method is 50-100nm, which is very small. The solid content of the cation amino silicone oil micro-emulsion is 10-36%. The cation amino silicone oil micro-emulsion has excellent shear stability, heat stability and storage stability, and is a favorable softener for finishing natural fibers, such as textiles made of cotton, hemp, silk, wool and the like, and synthetic fibers, such as polyester, polyamide and polypropylene ester.

Description

technical field [0001] The invention relates to a softening and finishing agent for textiles and a preparation method thereof, in particular to an amino silicone oil microemulsion and a preparation method thereof. Background technique [0002] Amino-modified silicone microemulsion is one of the most widely used modified silicone microemulsions at present. It is one of the products commonly used in the textile industry to improve fabric softness. The microemulsion has a small particle size and the shear resistance of the emulsion It has excellent shear stability, heat resistance stability and storage stability, and plays an important role in the softness of fabrics in the textile industry. Because the amino group can interact with the hydroxyl and carboxyl groups on the surface of the fabric, it can increase the resistance of silicone to fibers. Affinity, improve the washability of the fabric after finishing; amino can interact with the hydroxyl and carboxyl groups on the sur...
