Abstract

The invention relates to an aluminum-plastic plate and a composite processing technology thereof, and belongs to the technical field of building decorating materials. According to the technical scheme, the aluminum-plastic plate comprises an upper aluminum alloy plate, a substrate and a lower aluminum alloy plate, wherein the substrate is located between the upper aluminum alloy plate and the lower aluminum alloy plate, and the upper aluminum alloy plate, the substrate and the lower aluminum alloy plate are pairwise composited through polymer bonding films. The substrate in the middle is prepared from components in parts by weight as follows: 58-75 parts of polyethylene, 10-20 parts of maleic anhydride grafted polyethylene, 1-3 parts of nano-zinc oxide, 0.1-0.3 parts of dicumyl peroxide, 0.1-0.3 parts of triallyl isocyanurate and 15-28 parts of boron carbide micro-powder. The aluminum-plastic plate is stable in structure and firm to bond and has long-acting antibacterial, anti-radiation and anti-aging effects.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to an aluminum-plastic panel and a composite processing technology thereof. Background technique [0002] Aluminum-plastic panel, also known as aluminum-plastic composite panel, is composed of aluminum alloy panels on the upper and lower layers and a polyethylene core panel in the middle. It has the characteristics of light weight, easy processing, easy handling and installation, etc. Wall panels, renovation and renovation of old buildings, interior walls and ceilings, advertising signs, display stands, etc. [0003] Due to the wide application of aluminum-plastic panels and the need to adapt to a variety of environments, higher requirements are placed on the quality, peeling degree, and weather resistance of aluminum-plastic panels. In the prior art, a protective film or coating is usually pasted on the surface of the aluminum-plastic panel to improve the per...
