Plasma flame processor technology for surface treatment of automotive rubber organic polymer materials:
Using the plasma flame processor, the plasma high-energy particles and the surface of the organic material can physically and chemically react, which can realize the activation, etching and decontamination of the surface of the material, as well as the friction factor, adhesion and hydrophilicity of the material. The purpose of performance improvement.
The bonding of semi-components in the production process of multi-component rubber products such as automobile tires is a key indicator, and the bonding quality is particularly important during the molding process. The current production process semi-component bonding mainly relies on its self-adhesiveness and improving the bonding effect through surface grinding, brushing with glue or gasoline, etc.
The bonding performance of the semi-components is affected by the environment (such as temperature, humidity, light, ventilation, etc.), the expiration date of the rubber material (blooming), and dust. The process of applying mortar or gasoline is complicated and requires many process points. It is greatly affected by factors such as temperature and humidity. In seasons with large temperature differences, adhesion quality fluctuations are likely to occur. At the same time, it is not environmentally friendly, affects the health of the operator, and is safe. Serious shortcomings such as hidden dangers.

Nowadays, low-temperature plasma flame processor technology is widely used in the surface treatment process of materials in the automotive industry, such as the modification treatment of vehicle instruments, seats, engines, rims, car paint, and rubber seals. Practice has proved that this technology has a very significant effect on improving the surface properties of parts, and it has become the process of many parts and automobile manufacturers.
The essence of plasma high-energy ions are various particles in an ionized state. These particles include molecules, atoms, ions, electrons, photons, and neutral groups. The effect of low-temperature plasma on the surface treatment of polymer organic materials mainly has two forms, the physical effect of the ejection of charged high-speed moving particles on the surface of organic materials, and the chemical effect of particles with chemically active groups on the surface of organic materials. effect.
The energy of various particles in the plasma is several to several tens of volts, which exceeds the bonding energy of organic material molecules, and can effectively destroy the chemical bonds of organic macromolecules, thereby forming new chemical bonds. This energy only affects the surface of the organic material, and does not damage the material properties of the organic matrix.
The surface of the PTFE substrate is smoother before the plasma flame processor technology is modified, and the surface is densely covered with small pores after the modification, and the surface area of the material is relatively increased. The positive ions, electrons, neutral particles, excited atoms, etc. in the plasma can remove the weak boundary layer, oxidize and etch the surface of the material, and increase the surface roughness of the PTFE substrate.
Before the plasma technology modification, the surface tentacles of organic materials were particularly large, indicating that the surface energy of the materials was very low. The surface tentacles of the material after plasma modification are very small. This shows that the use of plasma technology can effectively increase the surface energy of organic materials, thereby improving the surface adhesion properties of organic materials.
PTFE material is a difficult-to-bond material with low surface energy and low friction factor. It has a small adhesive force. After the plasma technology of the plasma flame processor is modified, the surface introduces active groups, and the surface energy and surface roughness increase. Adhesive performance has been significantly improved.
After the rubber surface is modified with plasma flame processor plasma technology, the adhesion performance between components can be significantly improved, and the quality stability is better. Compared with the traditional polishing process, plasma technology has the advantages of simple process flow, convenient operation, high processing efficiency, energy saving, environmental protection, health, safety, etc., and has broad application prospects in the field of rubber bonding.
