Abstract

The invention discloses an aluminum alloy composite board and relates to the field of composite materials. The aluminum alloy composite board includes: an upper aluminum alloy layer, a barrier layer,a fireproof layer, a weather resistant layer, and a lower aluminum alloy layer, wherein the upper and lower aluminum alloy layers have same raw materials and include, by weight, 0.02-0.15% of Ce, 0.08-0.45% of La, 0.02-0.04% of V, 0.02-0.35% of Ti and the balanced of Al. The barrier layer is polyvinyl chloride film. The fireproof layer includes, by weight, 40-60% of an inorganic flame retardant, 10-20% of a dry powder fire extinguishing agent, and the balanced being titanium. The weather resistant layer is a PVDF film. The aluminum alloy composite board has excellent fireproof, heat-insulationand mechanical performances.

Description

technical field

[0001] The invention relates to a composite material, in particular to an aluminum alloy composite plate. Background technique

[0002] With the rapid development of society, people have higher and higher requirements for clothing, food, housing and transportation, especially for housing. They always feel that a stable residence is the basis of life. Safety requirements are getting higher and higher, not only environmental protection, sound insulation, heat insulation, but also fireproof and waterproof. Especially fire prevention, when a fire accident occurs at home, the loss is immeasurable, so fire prevention, heat insulation building and furniture materials are more and more popular among consumers, but at present, most of the new building materials on the market have single functions and cannot satisfy people's demands. Contents of the invention

[0003] In view of the above existing problems, the present invention provides an aluminum alloy composite...
