Embodiment 1

[0030] First of all, through mechanical processing, such as figure 1 The body shown is a wave spring with several sinusoidally formed washer-type springs in the circumferential direction;

[0031] Then, cover a nano anti-corrosion layer on the main structure, and this nano anti-corrosion layer is made by the following steps:

[0032] (1) Add polyether diol with a molecular weight of 3000, castor oil, and organoclay into the reaction kettle for mixing, and stir to raise the temperature. When the temperature rises to 60 °C, add toluene diisocyanate dropwise and finish adding in 40 minutes;

[0033] (2) Then heat and stir at 60 ℃ for 30 minutes, then raise the temperature to 80 ℃ and heat and stir, and take samples to measure the NCO value of the end group;

[0034] (3) When the NCO reaches 3.0%, cool down to 40°C, add styrene to the reaction system, stir for 30 minutes, and vacuum degas at 40°C for 30 minutes to obtain component A—polyurethane prepolymer; the polyether The mas...

[0041] First of all, through mechanical processing, such as figure 1 The body shown is a wave spring with several sinusoidally formed washer-type springs in the circumferential direction;

[0042] Then, cover a nano anti-corrosion layer on the main structure, and this nano anti-corrosion layer is made by the following steps:

[0043] (1) Add polyether diol with a molecular weight of 3000, castor oil, and organoclay into the reaction kettle for mixing, and stir to raise the temperature. When the temperature rises to 60 °C, add toluene diisocyanate dropwise and finish adding in 45 minutes;

[0044] (2) Then heat and stir at 60 ℃ for 40 minutes, then raise the temperature to 80 ℃ and heat and stir, and take samples to measure the NCO value of the terminal group;

[0045] (3) When the NCO reaches 3.0%, lower the temperature to 40°C, add styrene to the reaction system, stir for 40 minutes, and vacuum degas at 40°C for 35 minutes to obtain component A—polyurethane prepolymer; the p...

Embodiment 3

[0052] First of all, through mechanical processing, such as figure 1 The body shown is a wave spring with several sinusoidally formed washer-type springs in the circumferential direction;

[0053] Then, cover a nano anti-corrosion layer on the main structure, and this nano anti-corrosion layer is made by the following steps:

[0054] (1) Add polyether diol with a molecular weight of 3000, castor oil, and organoclay into the reaction kettle for mixing, and stir to raise the temperature. When the temperature rises to 60°C, add toluene diisocyanate dropwise and finish adding in 50 minutes;

[0055] (2) Then heat and stir at 60 ℃ for 50 minutes, then raise the temperature to 80 ℃ and heat and stir, and take samples to measure the NCO value of the terminal group;

Abstract

The invention relates to a wave spring with a nanometer erosion resistant coating. The wave spring with the nanometer erosion resistant coating is characterized in that a main body of a the wave spring with the nanometer erosion resistant coating is a washer type spring with a plurality of sine in the peripheral direction, the nanometer erosion resistant coating is covered on the main body structure, and the nanometer erosion resistant coating comprises, by weight, 20-80 parts of polyurethane, 40-80 parts of polyvinyl benzene and 1-10 parts of organic clay. The wave spring with the nanometer erosion resistant coating is simple in preparation technology, convenient to prepare, excellent in coating film performance, and low in cost.

Description

technical field [0001] The invention relates to an elastic element, in particular to a wave spring with a nano anticorrosion layer. [0002] Background technique [0003] As a basic part of mechanical equipment, springs are used in various fields such as modern industry, from ordinary machine tools to manned spaceflight, so that springs are basically used in places where there is machinery. With the deepening of the opening degree, however, in The imported machinery manufacturing industry, automobile, motor, national defense, ship, clutch and other hydraulic machinery industries have been continuously developed and other industrial equipment has been widely used in China. Elastic elements are often indispensable in these machines as mechanical parts. Due to the complexity of the application and the high frequency of use, the wear and corrosion of the elastic elements are also problems that need to be solved urgently. [0004] Paint is a supporting engineering material that...
