Aluminum alloy coated plate having formaldehyde removal function and manufacturing method thereof

Abstract

The invention relates to a coated plate, in particular to an aluminum alloy coated plate having a formaldehyde removal function. The aluminum alloy coated plate comprises an aluminum alloy plate basematerial and a surface film, wherein the surface film is formed by coating the aluminum alloy plate base material with a decorative film, a functional film and a protective film in sequence; the functional film is a base material film coated with a photocatalyst; the base material film comprises an ethylene/vinyl alcohol copolymer (EVOH); the photocatalyst comprises tungsten trioxide (WO3). The invention further discloses a manufacturing method of the aluminum alloy coated plate having the formaldehyde removal function. The manufacturing method comprises the following steps: step 1, pretreatment: cleaning the aluminum alloy plate base material, brushing glue onto the base material, then drying the base material, and conveying an aluminum alloy plate coiled material into a baking oven for heating before coating; step 2, coating: coating the aluminum alloy plate base material having the thickness of 0.45 mm with the PVC decorative film, the functional film and the protective film in sequence, thus obtaining a finished product. The aluminum alloy coated plate having the formaldehyde removal function has the characteristics of low cost and environmental friendliness, can effectively remove formaldehyde in an interior decoration process and has the bacteria removal property.

Description

technical field [0001] The invention relates to a film-coated board, which belongs to the technical field of decorative materials, in particular to an aluminum alloy film-coated board with formaldehyde removal function and a manufacturing method thereof. Background technique [0002] At present, with the increasing variety of decorative materials, the increasing luxury of various decorations and the increasing demand for decorative materials, people's environmental protection requirements for decorative materials are also getting higher and higher. At present, the materials used for interior decoration inevitably contain formaldehyde. Formaldehyde is a colorless, pungent gas with a strong smell, which can bind to proteins. Direct contact with formaldehyde on the skin can cause dermatitis, stains, and necrosis. Frequent inhalation of a small amount of formaldehyde can cause chronic poisoning, mucous membrane congestion, skin irritation, allergic dermatitis, etc., which will...
