Description
Technical Field
The application relates to the technical field of plastic electroplating, in particular to a plastic surface electroplating process.
Background
With the continuous development of modern science and technology and industrial production, plastics are widely applied in more and more fields. The plastic can make the parts with complex shapes formed in one step, and has the advantages of light weight, high strength and the like, so that the products processed by the plastic can save a large amount of metal materials, reduce machining procedures or lighten the weight of the products, reduce the production cost, improve the production efficiency and the like. In the automotive industry in particular, plastics are used for the production of door trims for automobiles.
The plastic car door guard plate has the defects of being not wear-resistant, non-conductive, not suitable for welding, easy to deform and the like, so that the special requirements of certain products cannot be met. It is therefore often subjected to a surface treatment to give it specific physical-chemical properties. At present, the surface of a car door guard plate made of plastic materials is electroplated, and a layer of metal coating is covered on the surface of the car door guard plate, which is the most common surface processing method.
However, the plastic door trim is a non-metal material, and the plastic door trim and the metal plating layer are mechanically bonded, so that the expansion coefficients of the two are greatly different when heated. Therefore, the binding force of the non-metal plating is poorer than that of the metal plating, and the conditions that the metal plating layer is easy to peel off and the service life of the car door guard plate is reduced exist.
Disclosure of Invention
In order to improve the bonding strength of metal coating and the door backplate of plastics material, prolong the life of door backplate, this application provides a plastics surface electroplating process.
In a first aspect, the present application provides a plastic surface electroplating process, which adopts the following technical scheme:
a plastic electroplating surface process comprises the following steps:
s1: stirring and mixing graphene, silica sol, epoxy resin, a curing agent and water, and adjusting the pH value to 5-6 to obtain mixed slurry;
s2: and (3) deoiling the plated part, washing for the first time, drying for the first time, spraying the mixed slurry on the surface of the plated part dried for the first time, drying for the second time, then carrying out chemical plating, washing for the second time, drying and electroplating to obtain an electroplated plastic finished product.
By adopting the technical scheme, on one hand, the silicon dioxide sol is hydrolyzed under the weak acidic condition, so that the hydroxyl content is improved; on the other hand, after the epoxy resin is adopted to adsorb graphene, the graphene can be combined with the hydrolyzed silicon dioxide sol through chemical bonds and hydrogen bonds. Therefore, the obtained mixed slurry has good conductivity and adhesion. The obtained mixed slurry is sprayed on the surface of a plated part, and a large number of hydroxyl groups in the mixed slurry are in chemical bond connection with the hydroxyl groups on the surface of the plated part, so that the bonding strength of the mixed slurry and the plated part is improved. Meanwhile, the strong conductivity of the plated part is beneficial to the subsequent chemical pre-plating and nickel electroplating, so that metal ions in the plating solution are reduced on the surface of the plated part to form a gold layer plating layer. Therefore, the mixed slurry is sprayed on the surface of the plated part, and then the plated part is subjected to electroplating treatment, so that the bonding strength of the plating layer and the plated part is improved, the plating layer is not easy to generate the conditions of bubbling, peeling and the like, the nickel plating process of the plated part is simplified, and the environmental protection performance of the nickel plating process is improved.
Preferably, the mixed slurry is prepared by mixing graphene, silica sol, epoxy resin, a curing agent and water according to the weight ratio of 1 (1.2-1.6) to (0.8-1.2) to (0.2-0.3) to (3-5).
By adopting the technical scheme, the mixed slurry is compounded by the raw materials in the proportion, the adhesion force of the obtained plastic finished product is 0 grade, the impact strength is as high as 600J/M, and after a 600h salt spray test, the surface of the plastic finished product has no obvious corrosion phenomenon.
Preferably, the graphene is further subjected to modification treatment, and the specific modification steps are as follows: and (3) carrying out oxidation treatment on the graphene, soaking the graphene in a metal salt solution, filtering and drying to obtain the modified graphene.
By adopting the technical scheme, the oxidized graphene can be polymerized with metal ions in a metal salt solution. Therefore, the surface of the obtained modified graphene has metal particles, so that the conductivity of the graphene can be further improved, the resistance of the surface of a plated part is lower, and the subsequent operations of chemical plating and electroplating on the plated part are facilitated.
Preferably, the spraying pressure of the mixed slurry is 0.15-0.3 MPa.
By adopting the technical scheme, the spraying pressure is favorable for uniformly attaching the mixed slurry to the surface of the plated part, the coating uniformity of the mixed slurry is improved, the bonding capacity of the mixed slurry and the hydroxyl on the surface of the plated part is improved, and the bonding strength of a final plating layer and the plated part is improved.
Preferably, after the first drying, the thickness of the mixed slurry on the surface of the plated part is 10-20 μm.

The weights of graphene, silica sol, epoxy resin, curing agent and water are shown in the table below.
The adhesion, impact strength and salt spray tests were conducted on the finished plastics obtained in examples 1 to 5, and the results are shown in the following table.
The data analysis on the above table shows that the adhesion force of the plastic product obtained by the plastic surface electroplating process in examples 1-5 is up to 0 grade, the impact strength is up to 590-600J/M, and no obvious corrosion phenomenon appears on the outer surface after the salt spray test for 600 hours. Therefore, the plastic finished product obtained by the electroplating process has high adhesive force of the plating layer and the plated part, and the plating layer is not easy to generate bubbling and stripping, so that the service life of the plastic finished product is prolonged.
The impact strength of the plastic products obtained by the plastic surface electroplating process of the examples 2 to 4 is as high as 600J/M, which is obviously higher than that of the plastic products obtained by the plastic surface electroplating process of the examples 1 and 5. Therefore, the impact strength of the finally obtained plastic finished product can be improved by mixing the graphene, the silicon dioxide sol, the epoxy resin, the curing agent and the water according to the weight ratio of 1 (1.2-1.6) to 0.8-1.2 to 0.2 to 0.3 to 3-5.

The plastic products obtained by the plastic surface plating processes according to examples 7-9 have significantly improved impact strength and salt spray resistance as compared to the plastic products obtained by the plastic surface plating process of example 2. Therefore, the reason why the spraying pressure of the mixed slurry is controlled to be 0.15-0.3MPa in the plastic surface electroplating process can improve the impact strength and the salt spray resistance of a plastic finished product is analyzed probably because the mixed slurry has stronger binding capacity with a plated piece and can be uniformly attached to the surface of the plated piece under the spraying pressure, so that the plated piece can be well protected, and the force required for damaging a plating layer and the plated piece is improved. Thus improving the impact strength and salt spray resistance of the finished plastic product.

The plastic products obtained by the plastic surface plating processes of examples 11 to 14 have significantly improved impact strength and salt spray resistance as compared with those of the plastic products obtained by the plastic surface plating process of example 10. Therefore, in the plastic surface electroplating process, the temperature for primary drying is controlled to be 90-110 ℃ and the time is controlled to be 10-15min, so that the impact strength and the salt spray resistance of a plastic finished product are improved.
The plastic products obtained by the plastic surface electroplating processes according to examples 12 to 14 have higher impact strength than the plastic products obtained by the plastic surface electroplating process according to example 11.

The plastic products obtained by the plastic surface plating processes of examples 15 to 17 have significantly improved impact strength and salt spray resistance as compared with the plastic products obtained by the plastic surface plating processes of examples 13 and 18. Therefore, in the plastic surface electroplating process, the secondary drying temperature is controlled to be 150-200 ℃ and the time is controlled to be 30-40min, which is beneficial to improving the impact strength and the salt spray resistance of the plastic finished product. The reason for analyzing the temperature is probably that the temperature has better curing film-forming effect on the mixed slurry, so that the mixed slurry is uniformly cured on the surface of a plated part, and the force required for damaging a plating layer and the plated part is improved. Therefore, the plastic finished product with high adhesion of the plating layer and the plated part, high impact strength and long salt spray resistance time can be obtained.
