Lightweight high-strength composite heat insulation aluminum plate

Abstract

The invention provides a lightweight high-strength composite heat insulation aluminum plate. The lightweight high-strength composite heat insulation aluminum plate comprises an upper aluminum plate layer, a middle heat insulation plate layer and a lower aluminum plate layer. The upper aluminum plate layer, the lower aluminum plate layer and the middle heat insulation plate layer are tightly connected by an adhesive. The heat insulation plate of the middle heat insulation plate layer is composed of 2-4% of aluminum borate whisker, 1-7% of water glass, 10-20% of ceramic powder, 0.5-5% of polyvinyl alcohol solution and the balance expanded perlite ore. According to the lightweight high-strength composite heat insulation aluminum plate, through reasonable compounding of the materials of the heat insulation layer and the enhanced spraying of the aluminum plate surface, the heat insulation and sound insulation effects of the composite aluminum plate are effectively improved, the mechanical properties such as strength and hardness are better, the combination between the layers is good, the effective life is prolonged by more than 2 times, and the overall performance is significantly improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation aluminum panels, in particular to a lightweight and high-strength composite thermal insulation aluminum panel. Background technique [0002] The traditional method of building exterior walls needs to use a lot of cement, sand, water and other materials, which is a waste of resources, and it is troublesome to build, large in size and quality, and there is a lot of garbage after demolition. Therefore, in order to improve the appearance and cost performance of the exterior walls, people Gradually find new materials to replace. [0003] Aluminum plate refers to a rectangular aluminum plate with a rectangular cross-section and uniform thickness made of pure aluminum or aluminum alloy materials through pressure processing (shearing or sawing), but a single aluminum plate has high cost, poor thermal insulation performance, and rigidity. Low-level problems require further processing improvemen...

AI Technical Summary

Problems solved by technology

However, there is still room for improvement in the performance of the thermal insulation aluminum plate, such as hardness, strength, thermal insulation, and sound insulation. Further composite processing is required to develop a new type of thermal insulation aluminum plate with good thermal insulation, sound insulation, and strong mechanical properties.
