Problems solved by technology

However, the amino-modified silicone oil prepared by these two synthesis methods will cause the softness of the fabric to decrease and the hand feel to be poor due to the structural change when the ordinary amino-silicon oil is modified, or none of them can achieve softness and slipperiness. Excellent crispness and rebound, long-lasting washability, and self-emulsifying function. Several advantages combined.

Abstract

The invention relates to a preparation method of a modified silicone oil finishing agent and in particular relates to a preparation method of an amino modified silicone oil finishing agent with a net-shaped structure. The preparation method comprises the following steps: after mixing terminal hydrogen-containing silicone oil with the hydrogen content of 0.01 percent to 0.08 percent with allyl polyalkoxy epoxy polyether and allyl alcohol polyoxyalkyl ether; synthesizing a terminal epoxy polyether modified silicone oil intermediate under the action of an acidic catalyst; mixing octamethyl cyclotetrasiloxane with a compound type amino silane coupling agent; synthesizing an amino co-modified silicone oil intermediate under the action of an alkaline catalyst; mixing the terminal epoxy polyether modified silicone oil intermediate with the amino co-modified silicone oil intermediate under the action of an organic solvent; carrying out amination reaction to obtain the amino modified silicone oil finishing agent with the net-shaped structure. Compared with the prior art, the amino modified silicone oil with the net-shaped structure has the performance characteristics of prominent hand feeling, good washing resistance, no yellowing, self-emulsifying performance and the like.

Description

technical field [0001] The invention relates to a preparation method of a modified silicone oil finishing agent, in particular to a preparation method of a network-structured amino-modified silicone oil finishing agent, which is mainly used for soft and smooth treatment in the post-finishing process of textiles. Background technique [0002] In recent years, with the continuous development of synthetic fibers, soft finishing is particularly important, and the properties of softeners are required to be more diverse and stable. [0003] Amino-modified silicone oil occupies the primary position in fabric softening and finishing agents, and its application is the widest and the amount of use is also the largest. After finishing the fabric with amino-modified silicone oil, in addition to showing excellent softness, its washability is also good, which is related to the polarity of amino-modified silicone oil and its ability to directional adsorb on the surface of the fabric. At p...
