Feasibility Study Report On Antibacterial Wood Coatings

With the development of society and the improvement of people's living standard,health and environmental protection have gradually become the primary choice of people.Because of microorganisms in the environment existing everywhere,human life and health have been threatened by various bacteria all the time.There are several antibacterial demands for facilities,tools,buildings and many other fields that people are often exposed to in their daily life and work.As a widely used building material which is directly contacted with human body,antibacterial coating has been attracting attention.This study aims at constructing industrial production project of antibacterial wood paint.In accordance with laws,regulations and the related principles of construction project in our country,a detailed feasibility analysis of the project construction of antibacterial coating is carried out from the geographical resources,project construction plan,environmental assessment,labor safety and fire protection,finance etc..In order to obtain the antibacterial coating with excellent comprehensive performance,four kinds of antibacterial agents,namely,nano-Cu₂O,nano-TiO₂/PANI,Quaternary Ammonium Salt 1227 and metronidazole,were added to coatings with different amount of 1%-5% to prepare different antibacterial coatings.Then,a comprehensive evaluation was performed on physical properties including impact resistance,hardness and flexibility and antibacterial performance of coatings.It was found that the coating with nano-TiO₂/ PANI composite antibacterial agent had the optimal comprehensive performance,which was the best choice for this project.Based on the geographical resource condition of the project construction factory,this paper emphatically analyzed the technical scheme,equipment scheme,project scheme and public auxiliary project.In addition,the environmental pollution caused by this project,occupational-disease-prevention and health care,fire prevention and building hygiene were also analyzed in detail and corresponding countermeasureswere put forward.Finally,considering all aspects previously mentioned,the financial evaluation and benefit analysis showed that this project had less investment and fast investment return,and had broad market prospect.
