Abstract

The invention discloses a fireproof aluminum-plastic panel for advertisements. The fireproof aluminum-plastic panel for advertisements consists of an upper aluminum plate, a PE plate and a lower aluminum plate in sequence, wherein the PE plate comprises the following raw materials in parts by weight: 20-40 parts of HDPE, 20-40 parts of LLDPE, 5-15 parts of maleic anhydride grafted polyethylene and 20-40 parts of fire retardant. The fireproof aluminum-plastic panel for advertisements, disclosed by the invention, is light in material, easy to carry, and capable of alleviating damages caused by earthquakes. The fireproof aluminum-plastic panel for advertisements is a safe fireproof material, which accords with the fire-resistant requirement of building laws and is halogen-free and environment-friendly. Moreover, the fireproof aluminum-plastic panel for advertisements is high in impact resistance and high in tenacity.

Description

technical field [0001] The invention relates to an aluminum-plastic board, in particular to an aluminum-plastic board for fireproof advertising. Background technique [0002] As a new type of decorative material, aluminum-plastic composite panels (also known as aluminum-plastic composite panels) have been introduced to China from South Korea since the late 1980s and early 1990s. , convenient construction method, excellent processing performance, excellent fire resistance and noble quality, it is quickly favored by people. [0003] Composed of two materials (metal and non-metal) with completely different properties, it not only retains the main characteristics of the original constituent materials (metal aluminum, non-metal polyethylene plastic), but also overcomes the shortcomings of the original constituent materials, and thus obtains many Excellent material properties, such as luxury, colorful decoration, weather resistance, corrosion resistance, impact resistance, fire r...
