Embodiment 1

[0060] Step 1: the preparation of airgel nanoparticles A: 10 grams of cellulose nanofibers (mass fraction is 1.51%) were mixed with deionized water, ultrasonic treatment was performed for 8 minutes to obtain a nanoparticle dispersion, and nanocellulose and N-( Add N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (KH-792) in a mass ratio of 2-aminoethyl)-3-aminopropyltrimethoxysilane (KH-792), mix , Stir the mixture at a speed of 700r / min for 2 hours at room temperature, freeze in liquid nitrogen for 30 minutes, vacuum freeze-dry for 24 hours, and dry in an oven at 100°C for 30 minutes to obtain KH-792 modified cellulose airgel nanoparticles .

[0061] Step 2: Preparation of Airgel Nanoparticles B: Mix 2 grams of cellulose nanofibers with deionized water, sonicate for 5 minutes to obtain a dispersion, add aqueous ethylenediaminetetraacetic acid, stir at room temperature for 28 hours, and filter with suction. Wash several times with ultrapure water, and dry at 95°C for 30 minutes...

Embodiment 2

[0064] Except that the mass parts of the KH-792 modified cellulose airgel nanoparticles in Example 1 are replaced by 3 mass parts, the mass parts of sulfurized seabuckthorn seed oil with a sulfur content of 3% are replaced by 20 mass parts, and the sulfur content is 3%. Except that the mass parts of sulfurized sunflower oil were replaced by 10 parts by mass and the mass parts of EDTA-modified cellulose airgel nanoparticles were replaced by 1 mass part, the remaining component contents and operating conditions were the same as in Example 1.

Embodiment 3

[0066] In addition to changing the cellulose airgel nanoparticles of 6 mass parts of KH-792 modification in Example 1 into 8 mass parts of 3-aminopropyltrimethoxysilane (KH-540), sulfur content 3% The mass parts of sulfurized seabuckthorn seed oil are replaced by 42 mass parts, the mass parts of sulfurized sunflower oil with a sulfur content of 3% are replaced by 7 mass parts and the mass parts of EDTA-modified cellulose airgel nanoparticles are replaced by 4 mass parts Except, all the other composition content and operating conditions are identical with embodiment 1.

Abstract

The invention discloses a modified aerogel nanoparticle, which is composed of an amino silane coupling agent modified nanoparticle and an EDTA modified nanoparticle, and the mass part ratio of the amino silane coupling agent modified nanoparticle to the EDTA modified nanoparticle is (2-4): 1.

Description

technical field [0001] The invention belongs to the technical field of nanoparticles, and in particular relates to modified airgel nanoparticles and their application in preparing airgel-loaded plant-based lubricating oil. Background technique [0002] Lubricating oil is a type of liquid or semi-solid lubricant widely used in automobile engines and mechanical equipment to reduce friction between two moving parts, thereby reducing wear between two parts in contact with each other. Lubricating oil generally consists of two parts: base oil and additives. Among them, the base oil constitutes the main component of the lubricating oil, which determines the basic properties of the lubricating oil; while the additive is an indispensable component of the lubricating oil, which makes up for some defects in the performance of the base oil and endows the lubricating oil with new properties. performance. [0003] At present, people carry out research from many aspects to improve the pe...
