Embodiment 1～25

[0035] Embodiment 1~25 is the preparation method example of polyol ester modified silicone oil

Embodiment 1

[0037] Add 26.1g of trimethylolpropane monoallyl ether, 60mL of toluene, and 52.5mL of triethylamine into a 250mL three-neck flask equipped with a condenser tube and a drying tube, stir and cool to 5°C under an ice-water bath, and slowly add 56.4mL of Octanoyl chloride, after the dropwise addition, continued to stir for 6h to complete the reaction. After the reaction finishes, filter off the triethylamine hydrochloride generated, and use 20mL of 10% NaHCO 3 Wash once with aqueous solution, wash with water until neutral, anhydrous Mg 2 SO 4 After drying, the solvent was distilled off under reduced pressure to obtain light yellow trimethylolpropane allyl ether dicaprylate with a yield of 94%.

Embodiment 2～5

[0039] According to a certain ratio, the trimethylolpropane allyl ether dicaprylate, toluene and catalyst (5% by mass percentage of chloroplatinic acid isopropanol solution) synthesized in Example 1 were added into the In the three-necked 500mL flask of the tube and the constant pressure dropping funnel, put 90g of low-hydrogen silicone oil (hydrogen content is 0.09, viscosity is about 700mPa·s, self-made according to the literature, the literature is: Ma Fengguo, Liu Chunxia, ​​Shen Wenling, high hydrogen-containing silicone oil Research on the preparation of low-hydrogen silicone oil by telomerization method, Silicone Materials, 2010, 24, 356-359) was diluted with toluene to a solution with a mass percentage of 60%, and then added to a constant pressure dropping funnel, started the stirrer, and Under protection, the temperature was raised to 90-100°C, and the diluted low-hydrogen-containing silicone oil was added dropwise to the reaction bottle within 1-1.5 hours, and then re...

Abstract

The invention relates to polyol-ester-modified silicone oil and a preparation method thereof, a carbon fiber oil solution, particularly a polyol-ester-modified silicone oil and a preparation method thereof, and a carbon fiber oil solution using the polyol-ester-modified silicone oil as a key component, belonging to the technical field of organic high polymers. The polyol ester with favorable heat resistance is directly connected to the siloxane side chain to obtain the novel polyol-ester-modified silicone oil, and the novel polyol-ester-modified silicone oil is used as a necessary component of a low-silicon carbon fiber oil solution to basically avoid the possibility of microscopic phase separation between the polyol ester and silicone oil, thereby obtaining the oil solution product with favorable microscopic compatibility; and besides, the polyol-ester-modified silicone oil simultaneously contains the siloxane chain segment on the main chain and the polyol ester chain segment of the side chain, and thus, has favorable compatibility for other added silicone oil compounds and organic ester compounds, thereby being beneficial to lowering the cost and regulating the formula of the carbon fiber oil solution.

Description

technical field [0001] The invention belongs to the technical field of organic polymers, and in particular relates to a polyol ester modified silicone oil, a preparation method thereof and a carbon fiber oil as a key component. Background technique [0002] Carbon fiber is widely used in satellites, launch vehicles, tactical missiles and other high-tech and civil industries such as automobile building materials. At present, most of the carbon fiber preparation methods adopt the following process: heating the raw silk in the presence of oxygen at 200-400 ° C to convert it into a refractory fiber, and then Carbonization and graphitization in an inert atmosphere above 1000°C yields carbon fibers with excellent mechanical properties. During the pre-oxidation and carbonization process, complex exothermic reactions often accompany the generation of volatile components and tar, making the fiber monofilaments Adhesion, thermal melting, and surface defects and hairs are generated dur...
