Abstract

The invention discloses a novel high-strength corrosion-resistant aluminum alloy video monitoring unit which comprises a protective shell. The protective shell comprises the following components in percentage by weight: 0.2% of Mg, 2.0% of Si, 4.0% of Cu, 0.2% of Mn, 0.2% of Fe, 0.1% of Zr, 0.1% of Er, 0.01% of Cr, 0.01% of Ni, 0.1% of Ti and the balance of Al. The protective shell is prepared by the following steps: (1) smelting; (2) adding three metal refinement modifiers Al-5Ti-B, Al-lOSr and RE; (3) standing under 100 MPa for 2 hours to form a cast ingot; (4) carrying out five-pass hot rolling, and carrying out three-pass cold rolling under ultrasonic vibrations; (5) modifying by using C and V lasers; and (6) carrying out surface treatment by using an octadecyl trichlorosilane solution to obtain the finished product. Multiple means are utilized to modify and treat the material of the protective shell, so that the protective shell can still keep the oxidation film complete under severe corrosion working conditions, thereby avoiding the metal inactivation and satisfying the requirements for industrial development at present.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a novel high-strength anti-corrosion aluminum alloy video monitoring equipment. Background technique [0002] At present, video surveillance equipment is generally divided into indoor units and outdoor units. According to different installation methods, it is divided into wall-mounted (suspended), hoisted and embedded (ceiling-mounted). The environment installation of the suspended ceiling, the wall-mounted type is generally suitable for outdoor or indoor environment installation without a suspended ceiling. In order to protect the electronic components in the video surveillance equipment, the video surveillance equipment includes a housing, which is generally made of metal materials. However, due to the long-term exposure of outdoor video surveillance equipment to harsh environments, the casing is easily oxidized and damaged. [0003] Aluminum alloys are the most widely used no...
