Abstract

The invention discloses a proportioning method of an aluminum-plastic composite cover. The aluminum-plastic composite cover is formed by an aluminum alloy cover and a plastic piece. The proportioning method of the aluminum-plastic composite cover is characterized in that the aluminum-plastic composite cover comprises the following raw materials by weight: 0.5-0.9 parts of Si, 0.5-1.0 part of Fe, 0.05-0.2 parts of Cu, 0.10-1.5 parts of Mu, Zu being more than or equal to 0.1 parts of Zu, less than or equal to 0.08 parts of Ti, more than or equal to 0.05 parts of Ag and the balance of Al. According to the proportioning method adopted by the invention, the lower-temperature ageing rate can be lowered, the hardening rate is increased suddenly along with the prolonging of time, so that the high-temperature ageing-hardening effect can be improved, and the hardness of aluminum alloy can be enhanced.

Description

technical field [0001] The invention relates to a method for proportioning parts of a packaging container, in particular to a method for proportioning an aluminum-plastic composite cover. Background technique [0002] At present, aluminum-plastic composite covers are more and more widely used in medical life. The commonly used aluminum-plastic composite covers are arranged in a four-point or six-point connection bridge structure around the riveted center hole on the aluminum cover. The center of the plastic cover After the riveting column and the central hole of the aluminum cover are positioned and docked, the central riveting column of the plastic cover is plasticized and deformed, and the composite cover is riveted outward. This kind of aluminum-plastic composite cover is processed at high temperature, and its low hardening rate is its fatal injury. It not only has low hardness, but also reduces production efficiency, increases production cost, and has limitations in use....
