Embodiment 1

[0014] Embodiment 1: drop into 400kg of double-ended hydrogen-containing silicone oil and 12kg of allyl glycidyl ether in an enamel kettle or a stainless steel reaction kettle, be warming up to 85 ℃ after stirring, add the isopropanol solution of chloroplatinic acid, and react the temperature after 15 minutes. Raise the temperature to 100-115°C, when the solution is transparent and clear, continue to react at 100-115°C for 1 hour, and finally at 110-120°C under reduced pressure, remove the residual allyl glycidyl ether for 30-60min. Low boiler to obtain double-ended epoxy silicone oil.

Embodiment 2

[0015] Embodiment 2: drop into 400kg of double-ended hydrogen-containing silicone oil and 20kg of allyl glycidyl ether in enamel kettle or stainless steel reaction kettle, be warming up to 80 DEG C after stirring, add the isopropanol solution of chloroplatinic acid, and the temperature increases after reaction 15min To 100-115 ℃, when the solution is transparent and clear, continue to react at 100-115 ℃ for 1 hour, and finally, under reduced pressure, at 110-120 ℃, after 30-60min, the residual allyl glycidyl ether is removed. Boiling to obtain double-ended epoxy silicone oil.

Embodiment 3

[0016] Embodiment 3: drop into double-ended hydrogen-containing silicone oil 400kg, allyl glycidyl ether 9kg in enamel kettle or stainless steel reaction kettle, be warming up to 85-90 ℃ after stirring, add the isopropanol solution of chloroplatinic acid, react after 15min The temperature was raised to 110-115°C. When the solution was transparent and clear, the reaction was continued at 100-115°C for 1 hour. Finally, under reduced pressure, the residual allyl glycidyl ether was removed at 110-120°C for 60-90min. Wait for the low boiler to obtain double-ended epoxy silicone oil.

[0017] The double-ended hydrogen-containing silicone oil described in the examples is prepared by the following preparation method, and the preparation method includes the following steps: adding 350-450 kg of octamethylcyclotetrasiloxane successively to the enamel reaction kettle, and the hydrogen-containing double seal The first 4-9kg, after stirring, add 8-15kg of concentrated sulfuric acid, keep t...

Abstract

The invention discloses double-terminated epoxy silicone oil and a preparation method thereof. According to the technical scheme, the preparation method comprises: adding 350kg to 450kg of double-terminated hydrogen-containing silicone oil and 8kg to 20kg of allyl glycidyl ether into an enamel kettle or a stainless steel reaction kettle; after stirring, raising the temperature to 70 DEG C to 95 DEG C; adding an isopropyl alcohol solution of a catalyst chloroplatinic acid; after reacting for 15min, raising the temperature to 90 DEG C to 120 DEG C; after the solution is transparent and clarified after the reaction, continually reacting for 1h to 2h at 90 DEG C to 120 DEG C; finally, under a decompression condition, removing residual low-boiling substances including the allyl glycidyl ether and the like under conditions that the temperature is 100 DEG C to 130 DEG C and the time is 30min to 90min, so as to obtain the double-end epoxy silicone oil. According to the double-terminated epoxy silicone oil and the preparation method thereof, provided by the invention, requirements on production conditions are low and time consumed by production is short, so that the production efficiency is extremely improved.

Description
