Embodiment 1

[0021] Heat 88.0g of 50# paraffin and 5.5g of diphenylsilanediol to 100°C, stir for 10 minutes to dissolve completely to obtain a paraffin system. Under the condition of high-speed stirring (500 rpm), 16.5g of nano-silicon nitride was added to the paraffin wax system, and the reaction was continued at 100°C for 10 minutes to make the stirring even, then the temperature was raised to 200°C, and the reaction was 2.5h. Add 0.5g of polymethacrylate at 100°C, stir evenly, let stand and cool to room temperature to obtain the product.

Embodiment 2

[0023] Heat 41.0g of 50# paraffin and 41.0g of base oil to 80°C, stir for 20 minutes to dissolve completely to obtain a paraffin system. Add 18.0g of nano-silicon nitride into the paraffin wax system under high-speed stirring conditions (600 rpm), continue to stir and react at 80°C for 15 minutes to make the stirring even, then raise the temperature to 190°C, react for 2 hours, stop heating, and let it stand for cooling The product was obtained at room temperature.

Embodiment 3

[0025] Heat 88.0g of 50# paraffin and 5.0g of diphenylsilanediol to 100°C, stir for 10 minutes to dissolve completely to obtain a paraffin system. Under high-speed stirring conditions (500 rpm), 16.5g of nano-silicon nitride was added to the paraffin wax system, and the reaction was continued at 100°C for 10 minutes to make the stirring even, then the temperature was raised to 180°C, 5.5g of expanded graphite was added, and the reaction was continued at 180°C. Stir at ℃ for 10 minutes to make the stirring uniform, then raise the temperature to 195℃, react for 1.0h, stop heating, let stand and cool to room temperature to obtain the product.

Abstract

The present invention discloses a solid nanometer particle-thickened paraffin aggregate and a preparation method thereof. The solid nanometer particle-thickened paraffin aggregate comprises paraffin, lubricating oil base oil, an additive and solid nanometer particles. The method comprises: firstly dissolving a structure stabilizer in a paraffin system, then adding the solid nanometer particles, stirring uniformly, refining at high temperature, finally adding the additive, and cooling to the room temperature to obtain the solid nanometer particle-thickened paraffin aggregate. The solid nanometer particle-thickened paraffin aggregate provided by the present invention can increase the dropping point of paraffin and is in a semifluid state without flowing within a range from melting point of paraffin to 280 DEG C, thus not only avoiding affecting of normal mixing and use conditions, also effectively solving a problem that paraffin flows and melts at high temperature in application.

Description

technical field [0001] The present invention relates to wax, more specifically, the present invention relates to a wax aggregate thickened by solid nano particles and a preparation method thereof. Background technique [0002] Now wax is widely used in various fields, but the melting point of wax is low, it is easy to separate from the system above the melting point, and the problem of high-temperature melting, flowing and deformation limits its application. [0003] People have done a lot of work to solve the problem of wax flowing and melting at high temperature. Cemil et al. (Preparation, Thermal Properties and Thermal Reliability of Form-Stable Paraffin / Polypropylene Composite for Thermal Energy Storage [J]. J Polym Environ, 2009, 17: 254-258) drop molten paraffin into polypropylene (PP) In the n-heptane solution, the mixed solution was placed at room temperature for 15 days to obtain a paraffin / PP phase change composite material, which has good chemical stability.
