Super material composite board and processing method thereof

Abstract

The invention provides a processing method of a super material composite board, which comprises the following steps: coating hot melt glue and a metal foil on the upper surface and / or the lower surface of a polystyrene base plate to form a pre-pressed composite board; and putting the pre-pressed composite board into a hot rolling machine for hot pressing to form the super material composite board, wherein the hot rolling machine is provided with a plurality of rollers. The processing method of coating the metal foil (such as copper coil) on the polystyrene base plate in a hot-pressing manner of the hot rolling machine provided with the plurality of rollers has the benefits that the rolling temperature of each group of rollers is gradually reduced from front to rear, so that the corrugation of the metal foil cannot be caused due to over-high cooling, thereby obtaining the super material composite board with flat surface; and through the processing method, the rolling pressure is not required to be distributed, so that the production process is simplified, the production efficiency is improved, the cost is reduced, no pollution exists, and the binding force generated by coating the metal foil satisfies the processing requirements of super materials. Therefore, the super material composite board can be widely applied to the processing field of super materials.

Description

【Technical field】 [0001] The invention relates to the field of supermaterials, in particular to a supermaterial composite plate for preparing supermaterials and a processing method for the supermaterial composite plate. 【Background technique】 [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some surface natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary properties inherent in nature. The properties and functions of metamaterials mainly come from their internal structure rather than the materials that make them up, so it is difficult to design and synthesize metamaterials. [0003] At present, the realization of the metamaterial structure is completed by making metal lines on the rigid PCB board. The ...

Problems solved by technology

[0004] However, due to the low polarity of the PS surface, its surface adhesion is poor, so its combination with copper is poor and cannot meet the requirements

At present, electroplating is used to coat the surface of PS with copper, but the cost of electroplating is high, there is a lot of waste water and waste liquid, and it has high pollution; it is also possible to use a hot roller machine to coat copper on the PS surface, although the bonding force of copper coating meets the requirements. The operation is simple, the production efficiency is high, the cost is low, and there is no pollution. However, due to the rapid cooling after rolling during the processing process, the thermal expansion coefficients of PS, hot melt adhesive, and copper foil are different, resulting in different shrinkage, resulting in copper foil. The problem of wrinkling, especially when processing large-sized substrates, can solve this problem if two-step copper pouring is used, but the entire process is doubled and production efficiency is reduced
