The invention belongs to the technology field of composite materials, more particularly relates to a high dielectric composite material containing fillers with a core-@-shell structure and a production method thereof. The composite material contains 10-45 wt% of aluminum and 55-90 wt% of polystyrene. The production method comprises the following steps: subjecting aluminum powder to surface passivation treatment to obtain fillers with a core-@-shell structure, preparing ethyl acetate solution of polystyrene, adding the treated aluminum powder into the ethyl acetate solution at different mass fractions, stirring, casting, sun-drying, oven-drying, molding and shaping to obtain the high dielectric composite material containing fillers with core-@-shell structure. An oxide coating is formed on the surface of the aluminum powder after the surface passivation treatment, so as to efficiently avoid the formation of leakage conductance due to mutual contact between eclectically-conducting additives and thereby to reduce the dielectric loss of the material. The composite material has high dielectric constant, low density and good flexibility. The production method of the composite material has the advantages of simple and controllable process, low hot-pressing temperature, energy conservation and environmental protection.

The present method provides a manufacturing method of fish skin glue jellies. The manufacturing method comprises the following steps: quick-frozen fish skins are thawed; the scales of the thawed fish skins are removed and the scale removed fish skins are washed for standby application; water is added into the fish skins, and the fish skins are heated to a temperature of 30-40 DEG C and boiled for 15-30 minutes; the boiled fish skins are screened using a 40-mesh screen, the fish skins are collected, and the collected fish skins are prepared into blocks or strips; water at 1-5 times of the mass of the fish skins is added, and the fish skins are heated to a temperature of 60-80 DEG C and boiled for 1-3 hours; the boiled fish skins are screened using a 60-mesh screen to collect a liquid phase and to obtain skin fish glue liquid; and the fish glue liquid is cooled and shaped to obtain the fish skin glue jellies. Diced fish flesh is also added into the fish skin glue liquid to prepare the fish skin glue liquid containing the fish flesh; and or white granulated sugar, fresh ginger water, Chinese prickly ash water and vitamin C are added to obtain the flavored fish skin glue liquid. The method is simple in technology, energy saving and environmentally protective, not high in requirements for the equipment in the production line, easy to control in processes and suitable for industrialized production. Besides, the obtained products are high in product added value and strong in plasticity, can be directly edible or matched with other seasoning for consumption, and are high in security and suitable for a wide range of populations.
