Problems solved by technology

[0004] Because the photocatalyst has such a good indoor air purification ability, many manufacturers try to combine it with furniture stably, but due to the diversity of the surface of the construction substrate, it is impossible for the same photocatalyst to have good adhesion to different substrate surfaces. focus on
Moreover, some photocatalysts also have a corrosive effect on the substrate.

Abstract

The invention discloses photocatalyst furniture and a coating construction process thereof. A primer layer and a photocatalyst coating are sequentially arranged on the outer surface of the photocatalyst furniture from interior to exterior; the primer layer comprises polyether-modified silicone oil and a modified silane coupling agent, the mass ratio of the polyether-modified silicone oil to the modified silane coupling agent is 5:8, the thickness of the primer layer is 1-500 microns, and the thickness of the photocatalyst coating is 50-500 microns; the coating construction process of the photocatalyst furniture comprises the following steps: the surface of the furniture is cleaned; the surface of the furniture is coated with the primer layer by film formation equipment; the primer layer is dried; the surface of the primer layer is coated with the photocatalyst coating by the film formation equipment; the drying is carried out in a clean environment, and the photocatalyst coating curing is waited for being realized. The photocatalyst furniture can have the effects of purifying, bacteria resisting, deodorizing and fouling resisting on indoor air and is durable; the coating construction process is simple and easily understood in steps; a coated coating is firm and durable, and has low possibility of peeling off.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a photocatalyst furniture and a coating construction process thereof. Background technique [0002] Furniture is essential in daily life, but whether it is made of solid wood or synthetic boards, it will inevitably release free formaldehyde and other toxic gases, polluting the indoor environment and affecting people's health. [0003] The photocatalyst is a multi-purpose photocatalyst, which has remarkable effects in air purification, antibacterial, deodorization, antifouling, water purification and so on. This is because the photocatalyst can form electron-hole pairs by absorbing light energy, thereby generating active oxygen negative ions, and the O adsorbed on its surface 2 and H 2 O acts to generate hydroxyl radicals, which oxidize and decompose organic matter into water and carbon dioxide, and organic matter containing sulfur, phosphorus, and nitrogen are converted into SO 4 2- ...
