Description
Technical Field
The invention relates to the technical field of plastic surface treatment, in particular to a surface treatment technology for an automobile decoration.
Background
The existing automobile decoration part needs to achieve the metal appearance effect, and hard rubber plastic is mostly adopted as a base material for surface treatment. With the increasing importance of the automobile consumption market on safety performance, the problem of sputtering damage caused by fragmentation and splashing of automobile parts adopting a hard rubber material as a base material due to safety accident damage is increasingly emphasized, and the automobile part sputtering damage problem becomes a research direction for automobile manufacturers to improve safety performance.
Compared with hard rubber plastic, soft rubber plastic has the advantages of wide elastic range, outstanding damping performance, excellent cold resistance, rich processing method and the like, so many automobile manufacturers pay attention to the use of soft rubber plastic as a base material for manufacturing automobile parts to avoid sputtering damage. However, due to the problem of the soft plastic property, the soft plastic is difficult to plate in the traditional electroplating process, and the plating layer is easy to fall off in the PVD process, so that the soft plastic can not be easily processed into a metal appearance effect, and the soft plastic is rarely used as a base material in a large amount on automobile decoration parts.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, provides the elastic automobile decoration with the metal appearance, solves the problems that the surface treatment of soft plastic is difficult to plate, the performance of a plating layer does not reach the standard, and the qualified automobile decoration product is difficult to manufacture, and promotes automobile manufacturers to improve the safety performance of automobiles.
The invention also aims to provide a method for producing the metal-appearance elastic automobile decorating part, and the method for producing the decorating part can effectively enhance the performance of a coating and improve the production yield and production efficiency of the decorating part product.
The purpose of the invention is realized by the following technical scheme:
The utility model provides a metal outward appearance elasticity automobile decoration, includes plastic base member, primer rete, PVD rete and finish paint rete, the plastic base member is flexible glue plastics, primer rete covers on the plastic base member surface, the PVD rete covers on primer rete surface, finish paint rete covers on PVD rete surface, wherein, the primer rete contains polyurethane modified epoxy acrylate resin and dipropylene glycol diacrylate resin.
In the above-mentioned metal-appearance elastic automobile decorative parts, a primer film layer is used for providing adhesion, metal bonding force and film ductility, a PVD film layer is used for providing a metal appearance, and a finish paint is used for providing wear resistance and scratch resistance of the surface of the decorative part. In the process of manufacturing hard-glue automobile decorating parts by using an approximate process, a hard-glue primer film layer usually adopts components containing bisphenol A type epoxy acrylate resin, trimethylolpropane triacrylate resin and pentaerythritol triacrylate resin, and the metal-appearance elastic automobile decorating parts manufactured by using the hard-glue primer film layer have the bad phenomenon of film layer falling because the three resins have poor flexibility. In order to adapt to the elasticity of the soft plastic, the scheme adopts the polyurethane modified epoxy acrylate resin and the dipropylene glycol diacrylate resin to replace bisphenol A type epoxy acrylate resin, trimethylolpropane triacrylate resin and pentaerythritol triacrylate resin as the components of the primer film layer, so that the defect of poor bonding force between the soft plastic and the film layer can be overcome while the metal appearance of the decorating part is ensured, and a series of functions of the film layer, such as stability, wear resistance, scratch resistance, corrosion resistance and the like, of the soft plastic meet the standards set by mainstream automobile manufacturers.
Specifically, the polyurethane modified epoxy acrylate resin is prepared by introducing a polyurethane chain segment into an epoxy resin main chain to modify epoxy acrylate resin prepared by esterification reaction of epoxy resin and acrylic resin.
Specifically, the primer film layer comprises, by mass, 10% -15% of polyurethane modified epoxy acrylate resin, 8% -12% of polyurethane acrylic resin, 15% -20% of dipropylene glycol diacrylate resin, 3% -5% of 1-hydroxy-cyclohexyl-phenyl ketone, 0.5% -1% of an auxiliary agent, and the balance of a diluent. The components of the primer film are polyurethane modified epoxy acrylate resin and polyurethane acrylic resin which are main components of the film, wherein the polyurethane functional group improves the flexibility and the binding force of the resin, and the modified epoxy functional group provides the reaction activity for binding all the components of the primer film. The dipropylene glycol diacrylate resin also improves the flexibility of the resin, and can increase the reaction rate and act to dilute the resin and provide leveling and fullness. 1-hydroxy-cyclohexyl-phenyl ketone is used as a photoinitiator.
Specifically, the PVD film layer comprises any one of indium and tin-chromium alloy, and the components have better paint layer binding force and processing stability, so that the appearance of the automobile decorating part is more stable, and chromatic aberration is reduced.
Specifically, the finishing coat film layer comprises, by mass, 15% -20% of polyurethane acrylic resin, 5% -8% of polyurethane acrylic resin with 2-6 carbon-carbon double bonds (C ═ C), 4% -6% of pentaerythritol triacrylate resin (PET3A), 3% -5% of a photoinitiator, 0.5% -1% of an auxiliary agent, and the balance of a diluent. The main performance of the finish coat film layer is determined by the components of polyurethane acrylic resin and polyurethane acrylic resin with 2-6 double bonds of C ═ C, so that the adhesion, coloring, hardness, wear resistance and other performances are provided for the finish coat film layer. The pentaerythritol triacrylate resin (PET3A) can improve the reaction rate of each component of the finish paint film layer, play a role in diluting the resin and provide leveling and fullness. The rest components are used as auxiliary materials. Compared with a hard glue finish coat film layer, the number of carbon-carbon double bond (C ═ C) functional groups in the polyurethane acrylic resin containing carbon-carbon double bond (C ═ C) is reduced, and therefore the flexibility of the finish coat film layer is improved.
The method for preparing the metal-appearance elastic automobile decorating part sequentially comprises the following steps of:
1) heating and shaping the soft plastic to form a plastic matrix of the elastic automobile decoration;
2) blending the primer according to the primer components, and coating the primer on the surface of the plastic matrix by adopting a spraying process to form a primer film layer;
3) Selecting any metal material of indium and tin-chromium alloy as a target material, and coating the metal target material on the surface of a primer film layer by adopting a gas-phase physical deposition process to form a PVD (physical vapor deposition) film layer;
4) blending finish paint according to the finish paint components, and coating the primer on the surface of the PVD film layer by adopting a spraying process to form a finish paint film layer;
5) and (4) cleaning the finished product obtained in the step (4) to form the elastic automobile decoration with the metal appearance.
Compared with the prior art, the invention has the following advantages:
1. the problem of insufficient binding force between a soft rubber material and a film layer is solved, the selection range of a base material for preparing the automobile decoration is expanded, and the soft rubber has a metal appearance and can reach the functional standard specified by mainstream automobile manufacturers in performance;
2. an elastic automobile decoration part is formed, and the part can effectively reduce the safety threat to a passenger in the process of fragmentation sputtering;
