Abstract

The invention discloses modified engineering plastic for manufacturing a 5G communication filter and a preparation method of the modified engineering plastic. The modified engineering plastic comprises the following components in parts by weight: 40-60 parts of base resin, 10-40 parts of glass fibers, 1-10 parts of a toughening agent, 0.1-1 part of a nucleating agent, 1-15 parts of fluorine-containing resin, 5-20 parts of a heat-conducting filler, 5-20 parts of filler, 0.1-2 parts of a coupling agent, 0.1-1 part of a lubricant and 0.2-1 part of an antioxidant; the base resin is polyphenylene sulfide resin or LCP resin; and the glass fibers comprise low-dielectric glass fibers with the dielectric constant of 4-7. The modified engineering plastic for manufacturing the 5G communication filterhas the characteristics of linear thermal expansion coefficient similar to that of aluminum alloy, low and stable dielectric constant, excellent heat resistance, heat dissipation performance, dimensional stability and the like, and the purpose of replacing a metal cavity can be achieved through plastic electroplating.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a modified engineering plastic used for making 5G communication filters and a preparation method thereof. Background technique [0002] Entering the 5G era, the number of base station antenna channels has grown significantly, gradually upgrading from the existing 4G channels of 4 and 8 to 16, 32, 64, and 128 channels. Since each channel requires a complete set of radio frequency components to receive and transmit uplink and downlink signals, and the corresponding filter is used to select and process the signal frequency, the demand for filters will increase significantly. [0003] Since the weight and volume of 5G equipment will be more stringent than that of 4G, 5G communication integrates the remote radio unit (RRU) and antenna into an active antenna unit (AAU). There are higher requirements for size and heat generation performance. The filter must be miniaturize...
