Embodiment 1

[0031] Embodiment 1 Preparation of high-temperature graphene fluorine-based grease of the present invention

[0032] step 1)

[0033] Take 44.6 parts of polytetrafluoroethylene ultrafine powder and 15 parts of perfluoroether oil, pour them into a low-speed mixer made of stainless steel plate for premixing, stir at 20 rpm for 8 minutes, and wait for the polytetrafluoroethylene to dissolve the perfluoroether The oil is completely absorbed and becomes sticky for later use;

[0034] step (2)

[0035] Put 0.2 part of graphene and 0.2 part of lubricant (esterified wax) statically and slowly on the center of the surface of the standby premix obtained in step (1); then 40 parts of grease (butter) are statically covered on graphene, lubricant In order to prevent the graphene and lubricant from being exposed, first stir at 10 rpm for 8 minutes, and then stir at 20 rpm for 8 minutes to obtain high-temperature graphene fluorine-based grease.

Embodiment 2

[0036] Embodiment 2 Preparation of high-temperature graphene fluorine-based grease of the present invention

[0037] step 1)

[0038] Take 44.7 parts of polytetrafluoroethylene ultrafine powder and 15 parts of perfluoroether oil, pour them into a low-speed mixer made of stainless steel plate for premixing, stir at 20 rpm for 8 minutes, and wait for the polytetrafluoroethylene to dissolve the perfluoroether The oil is completely absorbed and becomes sticky for later use;

[0039] step (2)

[0040] Place 0.1 part of graphene and 0.2 part of lubricant (Montan wax) statically and slowly on the center of the surface of the standby premix obtained in step (1); then 40 parts of grease (butter) are statically covered on graphene, lubricant In order to prevent the graphene and lubricant from being exposed, first stir at 10 rpm for 8 minutes, and then stir at 20 rpm for 8 minutes to obtain high-temperature graphene fluorine-based grease.

experiment example 1

[0049]Experimental example 1, the lubricating effect evaluation of high temperature graphene fluorine base lubricating grease of the present invention

[0050] The high-temperature graphene fluorine-based lubricating grease and contrast lubricant (universal lubricant) prepared by the embodiment of the present invention 2 are tried out in a plurality of enterprises, and the first occurrence of corrosion, jamming, deformation or loosening of the threaded parts of the machine after recording is used. The average time, the results are shown in Table 1.

[0051] It can be seen that compared with general-purpose lubricants, the use of the high-temperature graphene fluorine-based grease of the present invention can effectively reduce corrosion, jamming, deformation or loosening of machine threaded parts, so that the machine can run normally for a longer period of time. Therefore, the graphene fluorine-based grease prepared by the present invention has a more excellent lubricating eff...

Abstract

The invention provides a high-temperature graphene fluorine-based lubricating grease, which is prepared from the following raw materials in the weight ratio: 0.1-1 part of graphene, 14-21 parts of perfluoroether oil, poly Tetrafluoroethylene superfine powder 45-49 parts, lubricant 0.1-0.3 parts, grease 35-45 parts. The test results show that the high-temperature graphene fluorine-based lubricating grease prepared by the present invention has excellent lubricating effect, and it still exhibits long-term good lubricity even at high temperature working temperature, can reduce mutual friction between parts, and significantly wet the metal surface . In the long-term high-temperature state, even if the base oil gradually dries up, the graphene fluorine-based grease is supported by multiple guaranteed lubricants to play a lubricating role and continue to protect the connecting threaded parts of the machine from damage.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a high-temperature graphene fluorine-based grease and a preparation method thereof. Background technique [0002] Bolt, be indispensable when neutralizing in the middle of commercial production manufacture at daily life. The principle of the screw is to use the circular rotation of the thread and the friction, physics, and mathematics principles to gradually tighten the tool of the object, so that the industrial product forms a fixed piece. Screws can be divided into three categories according to their use: machine screws, set screws and non-standard screws. There are two types of mechanical screws. One is used to fasten threaded holes and fasten connections with parts with through holes. No nuts are required. This connection form is called screw connection, which is also a detachable connection; The other is to cooperate with nuts for fast connection between tw...
