Problems solved by technology

At present, in the coating of automobile wheels, the coating method is often complicated, the steps are cumbersome, and it consumes a lot of manpower and material resources.
[0006] The general production process of the existing coating method for aluminum alloy automobile wheels is: material grinding→primary pretreatment→powder spraying→powder grinding→secondary pretreatment→spraying color paint→spraying transparent paint→finished product packaging, The traditional coating process steps are complicated, the coating effect is poor, and the performance of the finished coating is average, which cannot meet the needs of use

Abstract

The invention relates to a primer for spraying an automobile wheel hub, and relates to the technical field of automobile wheel hub processing and production. The primer comprises the following components in parts by mass: 0.3-1 part of graphene, 33-46 parts of thermoplastic acrylic resin, 10-20 parts of titanium dioxide, 0.1-0.5 part of a graphene dispersing agent, 0.5-3 parts of a titanium dioxide dispersing agent, 0.1-0.5 part of an auxiliary agent and 29-56 parts of a solvent. The primer provided by the invention can enhance the adhesion of the primer and surface paint to a wheel hub, and the improvement of the bonding between the surface paint and the wheel hub is facilitated, so that the effect of enhancing the adhesion of the surface paint is exerted.

Description

Technical field: [0001] The invention relates to the technical field of automobile wheel hub processing and production, in particular to a primer for automobile wheel hub spraying and a preparation method thereof. Background technique: [0002] With the development of the motor vehicle industry, the output and stock of motor vehicles have increased, driving economic development and bringing convenience to people's travel. [0003] The wheel hub is an essential part of the car, and its performance is directly related to the smooth running and safety performance of the vehicle. However, the hubs of some wheels currently have the problem of weak impact resistance. [0004] After the aluminum alloy wheels are completed through machining and other key processes, considering the poor conditions of the aluminum alloy wheels in actual use, in order to reduce the oxidation of the aluminum alloy in the air and the loss of the wear of the wheel hub, the coating performance after coatin...
