Abstract

The invention provides a production process for photocatalyst film composite metal, and belongs to the technical field of metal. According to the technical scheme, the production process for the photocatalyst film composite metal comprises the following steps that a water solution of a peroxy titanium complex system with concentration of 0.1-5wt. % is prepared, a surface active agent is added into the water solution and a spraying solution is obtained; the clean and dry metal surface is coated with the spraying solution uniformly, high temperature calcining is conducted after surface drying, the calcination condition is controlled to be at a temperature of 300-700 DEG C for 20-120min and then cooling is conducted until the metal reaches the room temperature, and the photocatalyst film composite metal is obtained. The production process for the photocatalyst film composite metal has the beneficial effects that the production process steps are simple, time consumed in the process procedure is short, efficiency is high, and the production process can be widely applicable to production lines of all manufacturers, and investment is low; the abrasion resistance performance, the antibacterial performance and the formaldehyde degradation performance of a product are excellent, and air can be cleaned in high efficiency and the environment is improved; and the product has graceful gloss like organic gemstones and is high in grade, elegant and attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of metals, in particular to a process for making a photocatalyst film composite metal. Background technique [0002] Environmental pollution such as indoor decoration pollutants, bacteria and virus accumulation, and outdoor smoke emissions are becoming increasingly prominent in today's complex environment. The main indoor air pollutants such as formaldehyde, benzene, toluene, xylene, volatile organic compounds (VOC ), etc., mainly from boards, latex paints, wallpapers, adhesives, etc. used in interior decoration. Another serious threat to human health is the accumulation and residue of bacteria and viruses in the indoor environment, especially in places such as kitchens and bathrooms where food is placed, damp, and poor air circulation, which are prone to odors; in outdoor environments, car exhaust, factory smoke, etc. Air, etc., which are very easy to cause health problems, and are more and more concerned ...
