The coating structure aims to solve the problems that a layer of palladium is deposited on a nickel layer in a deposition manner and then a layer of gold is deposited in a replacementmanner in the existing process, and due to the magnetism of the nickel layer, loss and attenuation are caused during high-frequency and high-speed signal transmission, so that the requirement of high-frequency and high-speed signal transmission cannot be met. The coating structure comprises the silver layer, the palladium layer and the gold layer, does not have magnetism, does not affect high-frequency and high-speed signal transmission, and can protect the conducting layer and provide good weldability, conductivity, corrosion resistance, friction resistance and the like; and the silver layerreplaces gold (precious metal), the cost is remarkably reduced, the palladium layer on the silver surface can effectively prevent the silver layer from being corroded, and the gold layer can play a role in wetting and corrosion resistance.

The invention relates to a preparation method for a konjac glucomannan eye mask. The preparation method comprises the following steps of preparing a konjac glucomannan mixed solution, preparing a masksolution and preparing the mask. According to the preparation method, in the main raw materials, konjac glucomannan has excellent biological activity and rheological property, so that the water lossof skin can be prevented, and the aging can be relieved; soy protein isolate contains a plurality of essential amino acids of human bodies and trace elements and has very high nutritive value and health care effects; olive oil is rich in squalene which has excellent affinity with the skin and essential fatty acids of the human bodies and can be absorbed rapidly, and the elasticity and the moistureof the skin can be effectively kept; beewax is a pure natural moistening agent, and a protective film can be formed on the surface of the skin; collagen is composed of 19 amino acids and has the moisturizing, nourishing, skin tightening, wrinkle preventing effects; and glycerin has the effect of improving the moisturizing effect; monostearin has the emulsifying effect. The konjac glucomannan eyemask has the advantages of being water-retaining, wrinkle-resistant, natural, free of side effects and the like.
