Problems solved by technology

[0006] In the above two processes, when isopropanol is removed after synthesizing ternary copolymerized block silicone oil, since the amount of isopropanol removed is more, the viscosity of the product gradually increases, resulting in greater and greater resistance to stirring. The rate of isopropanol will be slower and slower, affecting production efficiency, and the gradual increase in viscosity also brings the risk of "cross-linking" of silicone crude oil in the reactor

Abstract

The invention discloses an environment-friendly ternary copolymerized segmented organic silicone finishing agent and a preparation method thereof. The environment-friendly ternary copolymerized segmented organic silicone finishing agent is prepared from the following components in percentage by weight: 20 to 40 percent of environment-friendly ternary copolymerized segmented silicon crude oil, 5 to 10 percent of emulsifier, 3 to 5 percent of cosolvent, 0.3 to 0.6 percent of glacial acetic acid and 50 to 70 percent of water. The environment-friendly ternary copolymerized segmented organic silicone finishing agent is prepared after the ternary copolymerized segmented silicon crude oil serving as a primary component is emulsified, so that the usage amount of a solvent is reduced, and the product cost can be lowered by 20 to 30 percent. The preparation method has the advantages of simple process, convenience in operation and control, stable quality and high production efficiency, and can be applied to large-scale industrial production.

Description

[0001] Technical field: [0002] The invention relates to a finishing agent for textiles, in particular to an environment-friendly ternary copolymerization block organosilicon finishing agent and a preparation method thereof. [0003] Background technique: [0004] At present, isopropanol, ethylene glycol monobutyl ether, etc. are often used as solvents in the process of preparing ternary copolymerized block silicone oil. The use of solvents has problems that cannot be ignored, such as increased product costs, polluted the environment, and greatly endangered people's health. For printing and dyeing enterprises that use a large number of ternary copolymerization block silicone oils, a solvent-free and environmentally friendly ternary copolymerization block silicone finishing agent has been developed. Meta-copolymerized block silicone oil is very necessary. [0005] When preparing environment-friendly terpolymer block silicone oil, two processes can be used: 1. Use isopropanol ...
