Description

A kind of Nanometer Copper mother particles of antibacterial plastics
Technical field
The invention belongs to technical field of polymer materials, particularly relate to a kind of Nanometer Copper mother particles of antibacterial plastics.
Background technology
Along with industrial expansion progress and the raising of people's living standard, people for product safety, life with And the requirement of working environment health is more and more higher.Plastics owing to having light weight, not corrosion, easy-formation, good insulating, not water suction etc. Advantage, becomes the manufacture raw material of various articles for daily use, the especially kitchen in being chronically at wet environment, bath articles field more It is to be widely used.Due to daily touched plastic, such as: phone, computer, washing machine, refrigerator, on and off switch, public transport The great majority such as handrail, chopping board, toilet do not possess antibacterial functions, and antibacterial is easy to stick to surface of plastic products breeding and propagates, Bringing bigger puzzlement to the health of people, this just requires that our daily used plastic has the function of antibacterial and mouldproof.
Antibiotic plastic is to give plastics anti-microbial property by adding antibacterial in the feed mostly.It is antibacterial that plastics are commonly used Agent mainly includes machine, inorganic, natural three big series, owing to inorganic antiseptic has antibacterial timeliness length, resistant to elevated temperatures feature, energy Enough adapt to plastic processing, be widely used in antibiotic plastic.Nano antiseptic plastic is inorganic nano-class antibacterial agent to be utilized Nanotechnology is scattered in plastic fully, can will be attached to the antibacterial on plastics and kills or suppress it to grow.Owing to receiving The special effects of rice flour body particle size, substantially increases overall antibacterial effect, makes high temperature resistant, powder fineness, dispersibility and effect Should be obtained for and give full play to, produce lasting antibacterial effect.
At present, inorganic antiseptic conventional on market is silver system and zinc series antibacterial agent, though silver-series antibacterial agent has higher Sterilizing ability, but owing to it has higher chemical potential 0.798 volt (25 DEG C), chemical stability is poor, shines at ultraviolet After penetrating down or being heated to uniform temperature, silver ion is reduced to argent, and is immediately converts into silver oxide, make goods graying, become Black, this not only lowers its commercial value, also reduce its anti-microbial property.Additionally, silver-series antibacterial agent price is higher, antifungal energy Power is more weak.Though zinc series antibacterial agent is without discoloration problem, low price, but its anti-microbial property is low, it is impossible to meet antibacterial requirement.
