Antiseptic and antibacterial wpc composite decking
With the improvement of people's living standards, people have higher and higher requirements for decoration products, and have higher and more urgent needs for environmental protection and health. Laying decking and carpets on the ground is an indispensable part of home decoration. However, decking is also the largest, most hidden, and most difficult to control indoor environmental pollution source in the home. Whether it is wpc composite decking, or between stone floors, floor mats and decking, there is a hygienic dead corner that is difficult to take into account and ignored by people. It condenses germs, insects, mites, ants and other organisms and microorganisms, which directly threaten people's health.
The existing treatment method is to sprinkle traditional pesticides under the decking. Although this method is useful for the prevention of pests, the pesticides themselves have toxic and side effects. Even if they have passed the inspection of the agricultural department and obtained the production license, they are only limited to agriculture and forestry. Production and other special purposes are not allowed to be used in home living environments. How to prevent the growth of bacteria from the top and bottom of decking is a problem that needs attention. As a new type of polymer composite material, wpc composite decking can play an antibacterial and bacteriostatic effect through additives.
Antibacterial agents can be mainly divided into four types: inorganic antibacterial agents, organic antibacterial agents, polymer antibacterial agents and composite antibacterial agents. Different antibacterial agents have different antibacterial action mechanisms and effectiveness against the same pathogen, and the same antibacterial agent has different antibacterial action mechanisms and inhibition ranges for different pathogens. In order to improve the corrosion resistance and antibacterial properties of wood-plastic decking, many scholars at home and abroad have begun to add various antibacterial agents to wpc composite materials and wpc composite decking to improve the anti-corrosion and antibacterial properties of composite materials.
At present, with the continuous improvement of people's health requirements, the safety and environmental protection of raw materials can no longer meet people's needs, and the antibacterial functionalization of furniture and indoor and outdoor decking has become an irreversible trend. Due to the different antibacterial mechanisms, advantages and disadvantages of each antibacterial agent, the antiseptic and antibacterial effects of wpc composite decking are also different. By analyzing the research status of anti-corrosion and antibacterial wpc composite composite materials, it is found that polymer antibacterial agents and various composite antibacterial agents are more and more favored by researchers at home and abroad due to their superior antibacterial properties.
