Embodiment 1

[0019] A preparation method of a diepoxy end-capping agent: Step 1. Add 814Kg of low-end hydrogen-containing silicone oil with a molecular weight of 1000 and 186Kg of allyl glycidyl ether into an enamel reaction kettle, heat to 70°C, and stir evenly; Step 2: Add 6g of chloroplatinic acid, seal the reaction kettle, and keep it warm at 70°C for 4 hours; Step 3: Vacuumize the reaction kettle for 30 minutes, cool down the reaction kettle with circulating cooling water, cool down to 35°C and discharge to obtain the product double Epoxy capping agent 1000Kg. The reaction principle is: under the catalysis of the catalyst chloroplatinic acid, the low-end hydrogen-containing silicone oil reacts with the coupling agent allyl glycidyl ether to form the diepoxy end-capping agent of the present invention.

Embodiment 2

[0021] A wool leavening agent includes a double epoxy end-capping agent. The wool leavening agent is prepared in the following way: 940Kg of octamethylcyclotetrasiloxane, 60Kg of diepoxy end-capping agent, and 600g of tetramethylammonium hydroxide are reacted in a closed reaction kettle at 90°C 1 hour, then raise the temperature to 110°C for 2 hours, then raise the temperature to 140°C for 1 hour, then vacuum for 30 minutes, add 72Kg of polyetheramine and 715Kg of ethylene glycol butyl ether after the temperature drops to 100°C, and heat up to 135°C After the insulation for 6 hours, finally cool to 35°C and discharge to obtain 1787Kg wool leavening agent.

Abstract

The invention provides a novel dual epoxy end-capping reagent, which is prepared through reactions between low hydrogen silicone oil and a coupling agent (allyl glycidyl ether) under the catalytic action of a catalyst (chloroplatinic acid). A novel wool raising agent is prepared from the dual epoxy end-capping reagent, octamethyl cyclotetrasiloxane, polyether amine, and ethylene glycol butyl ether. The production technology of the dual epoxy end-capping reagent is simple, at the same time, the dual epoxy end-capping reagent is used to synthesize a novel wool raising agent; the prepared wool raising agent is applied to finishing of wool fabrics and cashmere fabrics; the dual epoxy end-capping reagent has a very good end capping effect, thus the influence of branch chains of molecules is eliminated effectively, the effect on cashmere and wool is enhanced, the fluffiness and softness are both improved, and furthermore, the wool raising agent does not contain any formaldehyde, NP/APEO, orheavy metal and is environmentally friendly.

Description

technical field [0001] The invention relates to a diepoxy end-capping agent, in particular to a diepoxy end-capping agent and a preparation method thereof, a wool leavening agent containing the same, and a preparation method of the wool leavening agent. Background technique [0002] Wool leavening agent is a kind of shrinkage agent used for pre-treatment of wool and cashmere fabrics. The preparation process of traditional wool leavening agents is very complicated, and the fluffing effect after acting on wool and cashmere fabrics is average. The emergence of silicone has brought a leap forward in the finishing of sheep and wool cashmere fabrics, especially the wool leavening agent formulated with amino-modified silicone oil can greatly improve the softness, bulkiness and coolness of wool and cashmere fabrics. slippery. But its preparation process is very complicated, and the reaction process is not easy to control, and the processing effect on wool and cashmere fabrics has r...
