The invention provides a water-based finish paint with both high toughness and high hardness, and a preparation method and application thereof, the water-based finish paint comprises the following components by weight: 45-55% of water-based resin; 5-7% of amino resin; 3-6% of silver powder; 2-6% of a coalescing agent; 2-3% of a cross-linking agent; 1-5% of nano ceramic powder; 0.3-2% of a coupling agent; 13 to 30% of deionized water; and 0.6 to 2.4% of an auxiliary agent. The water-based finishing coat with specific components and proportions enables the product to have the properties of 0T and 4H at the same time; compared with oil paint, the water-based paint is more green, environment-friendly, healthy and safe, the product meets the ROHS technical standard, the VOC content is reduced, toxic and harmful substance composition in the paint is reduced, and a healthy and safe use environment is provided for production, transportation, storage, use and the like of paint and metal coiled material manufacturers.

The application relates to a communication device, a multi-frequency array antenna and a manufacturing method thereof, and the multi-frequency array antenna comprises a reflecting plate, at least one high-frequency subarray and at least one first phase shifter. The high-frequency subarray comprises a plurality of high-frequency radiation units which are connected with the reflecting plate and are arranged in sequence and at intervals. Since one of the main body part and the top panel shares the reflecting plate, the first phase shifter can be assembled simply, the material composition is reduced, the consistency and assembly efficiency of the antenna are improved, and the flexibility of the integrated antenna design is improved. In addition, the other part is integrally extruded and produced separately, the production efficiency is higher, the part can be replaced and maintained flexibly according to actual needs, the cavity design is flexible, the cavity spacing and boundary can be optimized according to the antenna design, and the design popularization and serialization of the antenna are facilitated. In addition, the main body part and the top panel of the cavity constituting the first phase shifter are easy to process and have few post-processes, are not prone to errors, and thus the yield is high and the replacement of the parts is facilitated.

The invention provides a calcite type flaky calcium carbonate grease and a preparation method thereof, and the method is as follows: 20-40 parts of high-alkaline calcium sulfonate, 10-30 parts of an organic solvent and 2-10 parts of distilled water are stirred uniformly at 20-50 DEG C. Then 2-8 parts of a morphology control agent is added, CO2 gas is introduced, and the reaction is carried out for 1-3 hours. Then solid-liquid separation, washing and drying are carried out to obtain a calcium carbonate thickening agent; 20-60 parts of calcium carbonate thickening agent powder, 40-80 parts of base oil are uniformly mixed, and stirring thickening reaction is carried out at 160+ / -10 DEG C for 30-90 minutes, then the temperature is continuously kept at 200+ / -20 DEG C for 10-20 minutes, and after cooling, grinding is carried out, and the calcium carbonate grease is obtained. The method has low cost, simple raw materials and preparation process, stable production batch, and can effectively solve the problems of unstable grease batch, complex preparation process and the like. The calcium carbonate grease prepared by the method has outstanding high-temperature tribological properties, the drop point is higher than 385 DEG C, the shear stability and extreme pressure performance are excellent, and the lubrication requirements under harsh working conditions such as high temperature and high load can be met.
