Problems solved by technology

[0003] At present, although the aluminum profile on the surface of the aluminum-plastic panel can withstand high temperatures, the plastic core layer is easily affected by the high temperature of the surface aluminum profile, resulting in excessive heating, smoke, spontaneous combustion, etc., and the flame retardancy is not ideal. The flame retardant of the core layer material basically adopts inorganic flame retardants, and the flame retardant performance is single, which fails to meet the current requirements for the flame retardant performance of the core material

Abstract

The invention relates to the technical field of aluminium-plastic panels, in particular to a fireproof aluminium-plastic panel containing a nanometer flame retardant and a core material special for the fireproof aluminium-plastic panel containing the nanometer flame retardant. The core material comprises the following raw materials in parts by weight: 45-55 parts of polyethylene, 25-30 parts of polycarbonate, 15-18 parts of modified enhanced nylon, 2-3 parts of the nanometer flame retardant, 1.5-2.5 parts of modified nanometer cerium oxide, 2-6 parts of a synergist, 3-8 parts of a compatilizerand 1-2 parts of a lubricant. The core material has excellent flame-retardant and fireproof performance, the mobility is high, a core layer can be easily produced through extrusion molding and injection molding, and the core layer produced by using the core material is high in strength and excellent in hardness, resists bending, is not liable to deform, and is excellent in weather resistance; andby adopting the nanometer flame retardant, through combined action of the nanometer flame retardant and the synergist, the core material can have the excellent flame retardant and fireproof performance, and not only can the synergist have an flame-retardant effect, but also a powder state of the synergist can promote the dispersity of materials, so that the rheological property of the core material in the subsequent technologies is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic panels, in particular to a fire-resistant aluminum-plastic panel containing a nano-flame retardant and a special core material thereof. Background technique [0002] The aluminum-plastic panel is made of two materials, metal and plastic, which not only retains the main characteristics of the original constituent materials, such as the light weight of the plastic, the corrosion resistance brought about by the compact surface structure of the aluminum profile, etc., but also overcomes the disadvantages of the original constituent materials. Insufficient, such as color decoration, weather resistance, corrosion resistance, sound insulation, heat insulation, easy processing and molding, etc., as a new type of decorative material, it is widely used in building exterior walls, curtain wall panels, old building renovations, interior walls And ceiling decoration, advertising signs, display stands,...
