Problems solved by technology

Among them, glass will not block the transmission of signals, but it is easy to attach fingerprints, which is difficult to process and high in maintenance costs; metal feels smooth, but it will cause great interference to signals; plastic will not block signals, and has a better heat dissipation effect, reducing manufacturing costs. Low, but it has a sense of cheapness, which is not conducive to its development in the direction of high-end

Abstract

The invention discloses a high-strength plate with metal coating and a preparation method thereof, which includes a substrate and a coating layer. The coating layer consists of a primer layer, a metal layer and a topcoat layer in sequence from the side close to the substrate to the side away from the substrate. The present invention consists of a substrate, a primer layer, a metal layer, and a topcoat layer. The primer layer has excellent properties. The metal layer uses vacuum coating to prevent the manufactured plate from affecting signal intensity. The topcoat layer has waterproof and oil-proof properties. , combined with the prepared mobile phone backplane, has a metallic appearance, smooth feel, good heat dissipation and anti-fingerprint performance, which can ensure the propagation of signals and is conducive to the development of the manufactured plates in the high-end direction.

Description

Technical field [0001] The invention relates to the technical field of plates, specifically a high-strength plate with metal coating and a preparation method thereof. Background technique [0002] With the advent of the 5G era, new technological changes will occur in the communication terminal industry such as mobile phones and tablet computers. Mobile phones have experienced many upgrades in just over 10 years. As the epitome of technological iterations, the casing is the protective umbrella of the mobile phone and will also The market is facing a reshuffle. Glass, metal, and plastic are the three mainstream materials for mobile phone backplanes. Among them, glass will not block the transmission of signals, but it is easy to adhere to fingerprints, is difficult to process, and has high maintenance costs; metal feels smooth, but will cause great interference to signals; plastic will not block signals, has better heat dissipation effects, and has lower manufacturing costs. L...
