Description

technical field [0001] The invention belongs to the technical field of modified high molecular polymer resins, in particular to a ceramic micropowder masterbatch, a polymer composite material with a ceramic texture and a preparation method for the two. Background technique [0002] 5G signals have the advantages of high transmission, low latency, and wide signal coverage. Since 5G uses a high-frequency frequency band above 5MHZ, the signal transmission is susceptible to interference. In addition, the wireless charging function requires non-metallic materials such as 3D glass or ceramics to better realize the above functions. In the future, foldable mobile phones and flexible displays OLED or QLED will be used, and 3D glass or ceramics will become the mainstream choice of rear shell materials. Aiming at the trend of 5G future materials, many domestic enterprises also participated in the discussion, and believed that the solution is inseparable from the research and developme...

Problems solved by technology

[0005] 1. Ceramic micropowder has obvious damage to the physical properties of materials. When the amount of ceramic micropowder is slightly larger, the physical properties of the polymer will be significantly reduced, and it is not suitable for use in some application fields that require relatively high mechanical properties of materials. Limit the scope of application of composite materials;

[0006] 2. Ceramic micropowder is a non-organic material, which has poor compatibility with high molecular polymer materials. It is difficult for inorganic ceramic micropowder to disperse evenly in the polymer substrate, which will affect the mechanical properties of the composite material, and the composite material will also appear larger. performance fluctuations;

[0007] 3. The bulk density of ceramic micropowder is quite different from that of high molecular polymer resin. In the process of stirring, mixing and blanking, the accumulation of ceramic micropowder and the phenomenon of stratification in the process of blanking are prone to occur, which affects the production and manufacture of composite materials.
