Example Embodiment

[0023] Example 1: When the anti-aging agent is gas, the material to be treated is nitrile rubber, and the anti-aging agent is XeF2. The anti-aging treatment steps of low-temperature plasma rubber are as follows:

[0024] Step 1: Clean and remove impurities such as oil and dust on the surface of the nitrile rubber 8, and install the nitrile rubber 8 on the electronically controlled movement platform 9;

[0025] Step 2: Convert XeF 2 The anti-aging agent gas 2 is passed into the ionization tube 1, and the air in the ionization tube 1 is drained;

[0026] Step 3: Turn on the high-voltage pulse power supply 5 and set the XeF 2 The anti-aging agent gas 2 is ionized, and the discharge frequency and flow control valve 7 are adjusted to ensure that the aging agent gas is completely ionized and blown to the surface of the rubber 8;

[0027] Step 4: Control the movement of the moving platform 9 to ensure that all the rubber surfaces are blown by the gas ions 7, so that all the surfaces of the ru...

Example Embodiment

[0028] Example 2: When the anti-aging agent is solid, the anti-aging treatment steps of low-temperature plasma rubber are as follows:

[0029] Step 1: Clean and remove impurities such as oil and dust on the surface of the rubber part 8, and install the rubber part 8 on the electronically controlled movement platform 9;

[0030] Step 2: After the anti-aging agent is heated, the anti-aging agent gas is obtained, and then the anti-aging agent gas is passed into the ionization tube, and the air in the ionization tube is drained;

[0031] Step 3: Turn on the high-voltage pulse power supply, ionize the anti-aging agent gas, control the flow of the anti-aging agent gas, and blow the gas ions to the surface of the rubber part;

[0032] Step 4: Control the movement of the moving platform to ensure that all the rubber surfaces are blown by the ionized gas, so that all the surfaces of the rubber parts are treated with anti-aging.

[0033] Example 2: When the anti-aging agent is liquid, the materia...

Abstract

The invention relates to an anti-aging treatment method for rubber with low temperature plasma. The treatment method is characterized in that the treatment method comprises the steps of mounting a clean rubber part with impurities being removed on an electrically-controlled motion platform, filling anti-aging agent gas into an ionization tube, exhausting air in the ionization tube, switching on a high-voltage pulse power supply to ionize the anti-aging agent gas, moving the electrically-controlled motion platform, allowing the ionized gas to be blown the surface of the rubber part, and conducting anti-aging treatment on the whole surface of the rubber part. Compared with the conventional treatment method, the anti-aging treatment method has the advantages that: 1, as the plasma is higher in energy, a molecular bond and a chemical bond on the surface of the rubber can be opened, impurity molecules on the surface of the rubber can be removed, the surface adsorption activity of the rubber can be improved, a binding force of the surface of the rubber with an anti-aging coating can be greatly increased, and 2, anti-aging agent ions are chemically bonded with a rubber surface material easily, a deeper anti-aging layer is formed, the problems of weak binding force, and high possibility of falling and breaking do not exist, and the uniformity of a protective layer can be greatly improved through the processing of the electrically-controlled motion platform.

Description

technical field [0001] The invention relates to the field of surface modification of rubber materials, in particular to a method for treating the surface of rubber materials with low-temperature plasma. Background technique [0002] Rubber products are widely used in tires, soft fuel tanks, sealing products, shock absorbers, pilot life support systems, etc. due to their good elasticity, convenient synthesis, and various types, and their role is very important. Rubber products are subjected to mechanical stress, oxygen, light, etc. during use, especially on aerospace vehicles, the external environment has more stringent requirements on the performance of rubber products than normal ground conditions, and physical properties are deformed, brittle, Cracking, mildew, loss of gloss and color change, swelling, change of rheological properties, etc. In terms of mechanical properties, the tensile strength, elongation at break, impact strength, bending strength, compression rate, el...
