Transparent foamed aluminum composite board and preparing method thereof

Abstract

The invention discloses a transparent foamed aluminum composite board and a preparing method thereof. According to the method, a UV resin coating is attached to a foamed aluminum board base body surface, the UV resin coating is epoxy crylic acid or crylic acid polyurethane or unsaturated polyester or crylic acid polyester or crylic acid ether resin, and the UV resin coating is higher than the foamed aluminum board base body surface by 1 mm in the thickness direction. The preparing method includes the steps that the foamed aluminum board surface is input into a die after being processed, the foamed aluminum base body surface put in the die is brushed with UV resin, and the coating needs to be higher than the foamed aluminum base body surface by 1 mm in the thickness direction; the foamed aluminum base body surface evenly brushed with the UV resin is put under an ultraviolet light source to be irradiated and cured, and the transparent foamed aluminum composite board is prepared. According to the transparent foamed aluminum composite board and the preparing method thereof, the sound absorption and noise reduction function of foamed aluminum is kept, the strength of the foamed aluminum is improved, corrosion resistance is achieved, in addition, the UV resin coating has good transparency, the aesthetics character of the porous structure of the foamed aluminum can be maintained, and the transparent foamed aluminum composite board and the preparing method thereof can be applied to decoration in the fields of buildings, arts and the like.

Description

technical field [0001] The invention relates to a composite material formed of polymer material and porous metal, in particular to a composite plate of UV resin and closed-cell foamed aluminum. Background technique [0002] Aluminum foam has attracted wide attention in the field of construction due to its sound absorption, light weight, shock absorption and many other functions. However, aluminum foam itself has low strength and poor corrosion resistance, which greatly limits the specific application of aluminum foam. Most of the existing aluminum foam composite materials are stone-based, with stone as the decorative layer and aluminum foam as the sandwich layer. Although these composite boards improve the strength of the panel, they fail to give full play to the lightweight structure of aluminum foam during use. Advantages, and the stone is fragile, which brings certain difficulties to the construction. In addition, the aluminum foam composite sheet with a sandwich structu...

[0002] Foamed aluminum has attracted widespread attention in the field of construction due to its sound absorption, light weight, shock absorption and many other functions, but the foamed aluminum itself has low strength and poor corrosion resistance, which greatly limits the specific application of foamed aluminum

Most of the existing aluminum foam composite materials are stone-based, with stone as the decorative layer and aluminum foam as the sandwich layer. Although these composite boards improve the strength of the panel, they fail to give full play to the lightweight structure of aluminum foam during use. advantages, and the stone is fragile, which brings certain difficulties to the construction

In addition, the sandwich structure aluminum foam composite sheet of the metal surface also has problems such as heavy sheet weight and high production cost.

In recent years, polymer materials and aluminum foam composite materials have been developed successively. The Chinese invention patent application with the application publication number CN103113715A discloses a preparation method of epoxy resin and closed-cell aluminum foam composite materials. The epoxy resin produced by this method Composite materials with closed-cell aluminum foam have the characteristics of high yield strength, but the poor transparency of epoxy resin restricts the application of this material in art and decoration fields that need to reveal the pore structure of foam aluminum
