(Summary description)Which automobile plastic parts can be sprayed with small plasma spraying equipment: Plastic products not only reduce the weight of the car body, reduce energy consumption, but also ensure function and safety; through different surface treatment processes, the comfort and decoration of the products are continuously improved. Before silk-screening, bonding, coating and other processes on plastics, the traditional surface treatment methods are manual polishing, flame burning and spraying primer. Now let’s discuss the application of small plasma spraying equipment in the surface treatment of automotive plastic parts. . Small plasma spraying equipment is widely used in the surface treatment of automotive plastic parts. Plastic parts account for more than 1/3 of the total automotive materials, most of which are composite materials, such as PP, ABS, PA, PVC, EPDM, PC, EVA, respectively Processed into bumpers, dashboards, central control panels, door panels, protective panels, engine covers, sealing panels, lamps, shockproof pads, etc. The composite material is made of a combination of multi-physical materials, which can complement each other's strengths and obtain excellent properties that a single material cannot achieve, such as polypropylene (PP) + glass fiber (GF20), polypropylene (PP) + EPDM rubber (EPDM) + Talc (TD20), etc., are widely used in automotive interior parts. Materials similar to PP, EPDM, and ABS+PC have low surface energy and poor wettability, which will affect the quality and surface performance of the screen printing, bonding, coating, and flocking of the material. After using small plasma spraying equipment to process the above materials, it is found that under the action of plasma active particles, the surface performance of the material has been greatly improved, and the tearing ability has also been greatly improved. From the analysis of the results, it can be seen that there are two main reasons: 1. The plasma discharge generated by the small plasma spraying equipment can introduce hydrophilic groups on the surface of the material, such as the hydroxyl group (OH) of the phenol group, the carboxyl group (-COOH) and the carbonyl group (C=O) of the carboxylic acid, thereby improving the surface of the material. The wettability greatly improves the adhesion and bonding strength of the substrate surface. 2. The plasma generated by the small plasma spraying equipment promotes the opening of the molecular bonds of the material, and the cross-linking effect and low molecular weight contaminants are removed. The surface of the material forms a clean and strong contact surface layer, which can also improve the bonding of the contact surface. Strength and binding power. Automotive plastic parts of various shapes and materials can be surface treated with small plasma spray equipment for flocking plastic parts. Not only can the quality control of flocking be guaranteed, but also adhesives that are harmless to the human body and the environment can be selected to reduce the health risks of the operator. Use vacuum plasma spray equipment to perform surface treatment before covering plastic door panels made of polypropylene (PP) + talcum powder (TD20) to enhance the bonding performance of the water-based polyurethane adhesive and plastic parts and improve the tearing force. Plastic products after surface treatment by small plasma spraying equipment, their bonding strength and bonding strength are the same as the electrode structure of the vacuum chamber of plasma surface treatment, discharge vacuum degree, gas type and ratio, gas flow size, treatment time, power supply, etc. The parameters are closely related; the plasma surface treatment has a certain timeliness, so the relevant production should be completed as soon as possible.
