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 is finished, filter off the generated triethylamine hydrochloride, 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, trimethylolpropane allyl ether dicaprylate, toluene and catalyst (5% by mass percent isopropanol solution of chloroplatinic acid) synthesized in Example 1 are added into the mixture with mechanical stirring, spherical condensation In the three-necked 500mL flask of the tube and constant pressure dropping funnel, put 90g of low hydrogen-containing 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 of 60% by mass, 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 b...

Abstract

A polyol ester modified silicone oil, a preparation method and a carbon fiber oil agent belong to the technical field of organic polymers, and in particular relate to a polyol ester modified silicone oil, a preparation method thereof and a carbon fiber oil agent as a key component. In the present invention, polyol esters with good heat resistance are directly connected to siloxane side chains to obtain a new type of polyol ester-modified silicone oil, and it is used as an essential component of low-silicon carbon fiber oils, fundamentally Avoid the possibility of microscopic phase separation between polyol ester and silicone oil, and obtain oil products with good microscopic compatibility; in addition, because this polyol ester modified silicone oil contains both siloxane segments on the main chain and poly Alcohol ester chain segment, so it has good compatibility with other silicone oil compounds and organic ester compounds added, which is beneficial to reduce costs and adjust the carbon fiber oil formulation.

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...
