Embodiment 1

[0025] 9.3 kg of pre-dried triethanolamine, 0.5 kg of flake zinc powder, and 0.2 kg of molybdenum disulfide were mixed in a plastic mixer for 1 minute and discharged. The mixed materials were blended and granulated in a twin-screw extruder, and the temperature of the extruder was set at 160° C. to prepare a modified triethanolamine material for a three-layer composite material.

Embodiment 2

[0027] 6.4 kg of pre-dried triethanolamine, 3.0 kg of flake copper powder, and 0.6 kg of polytetrafluoroethylene were mixed in a plastic mixer for 1 minute and discharged. The mixed material was blended and granulated in a twin-screw extruder, and the temperature of the extruder was set at 170° C. to prepare a modified triethanolamine material for a three-layer composite material.

Embodiment 3

[0029] 8.5 kg of pre-dried triethanolamine, 0.5 kg of flake copper powder, 0.5 kg of flake zinc powder, 0.2 kg of molybdenum disulfide, and 0.3 kg of graphite were mixed in a plastic mixer for 2 minutes and discharged. The mixed materials were blended and granulated in a twin-screw extruder, and the temperature of the extruder was set at 185° C. to prepare a modified triethanolamine material for a three-layer composite material.

Abstract

The invention relates to a preparation technology of novel modified triethanolamine. A material is prepared from the following ingredients in percentage by weight content: 64 to 93% of triethanolamine, 5 to 30% of alloyed powder and 2 to 6% of tetrafluoroethylene, wherein the alloyed powder is flaky single powder of copper powder, copper alloy powder or zinc powder or a mixture of the copper powder, the copper alloy powder or the zinc powder; and the tetrafluoroethylene is prepared from single powder of polytetrafluoroethylene, molybdenum disulfide or graphite or a mixture of the polytetrafluoroethylene, the molybdenum disulfide or the graphite. The composite material can be prepared by a plastic processing conventional twin-screw extruder through extrusion and granulation. Compared with the prior art, a three-layer composite material bearing prepared by the invention has the advantages of good heat conductivity, bearing capacity, abrasion resistance and the like.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a preparation process of novel modified triethanolamine. Background technique [0002] Triethanolamine has good self-lubricating property and low coefficient of friction because of its molecular chain has a smooth profile. And because it is a linear high-crystalline polymer with flexible chains, high crystallinity and large bond energy, it is not easy to transfer to the opposite grinding surface, and it has inherent good wear resistance and high strength. It is a resin whose specific strength is closer to that of metal among all plastics. One of the varieties, it is widely used in the manufacture of various parts in the fields of machinery, automobiles, electronic appliances, etc. [0003] However, when common triethanolamine is used as a friction part under the condition of high relative speed and heavy load, due to insufficient lubrication, the heat generated by fricti...
