Abstract
Invention discloses a kind of high-performance antibiosis composite material and preparation method, the high-performance antibiosis composite material is mainly prepared by following components according to parts by weight: 35~95 parts of polyphthalamide (PPA), ethylene-methyl methacrylate ethylene oxidic ester -5~50 parts of methyl acrylate (E-GMA-MA), 0.5-35 parts of nano-silver powder, 0.5-35 parts of nano-titanium dioxide, 5-15 parts of dispersing agent, 0.1~1.5 part of coupling agent, 0.5~1 part of antioxidant.PPA/E-GMA-MA thermostability engineering plastic alloy material is as skeleton selected in the present invention, antimicrobial composite material is assigned with excellent high temperature resistant, high intensity, the performance of high tenacity, and improve the restraining and sterilizing bacteria efficiency of antimicrobial composite material, the use scope for expanding composite material, allows to be widely used on the environmental unit components of high-temp resisting high-humidity resistings such as military project, nuclear power, high-speed rail tunnel bridge.
Description
Technical field
The present invention relates to functional engineering plastic materials field, specifically a kind of high-performance antibiosis composite material and its preparation
Method.
Background technique
Anti-biotic material refers to that itself has a kind of new function material killed or inhibit microbial function, leads in military project
There is extremely wide application prospect in the fields such as domain, medical field, civilian food packaging.With the expansion of the application range of plastics,
The application field of antibiotic plastic is further extended.Now, with the raising of the comprehensive performances such as high temperature resistant, high intensity, work
Engineering plastics are gradually applied to military project, high-speed rail highway, oil field, to meet by the substitute as conventional metals product
It loss of weight to product and corrosion-resistant etc. requires.But in use, especially in wet environment, frosting is easy
Cooperating microorganisms and algae will have a direct impact on the service performance of equipment and product when situation is serious.Currently, being directed to high temperature plastics material
The research and development of the anti-microbial property of material are also rarely reported.
Therefore, it still needs further improvement for existing plastic material.
Summary of the invention
The present invention is this compound in view of the above-mentioned problems, provide a kind of high-performance antibiosis composite material and preparation method
The comprehensive performance that material has excellent anti-microbial property, high temperature resistant, intensity high, does not have antibacterial to solve existing high performance material
The problem of performance.
Technical scheme is as follows:
The present invention provides a kind of high-performance antibiosis composite material, and the composite material is mainly by following components according to parts by weight
Number is prepared:
35~95 parts of polyphthalamide (PPA), ethylene-methyl methacrylate ethylene oxidic ester-methyl acrylate (E-
GMA-MA) 5~50 parts, 0.5-35 parts of silver powder, 0.5-35 parts of titanium dioxide, 5-15 parts of dispersing agent, 0.1~1.5 part of coupling agent,
0.5~1 part of antioxidant.
Nano-silver powder due to being nanoscale particle, due to its structural unit size between macroscopic material and microcosmic atom and
Between molecule, special skin effect, small-size effect, quantum size effect and macro quanta tunnel effect are shown, it can be with
It easily enters in microbial body, large specific surface area, expands the active position of particle surface, afterwards and carefully into cell membrane (wall)
The sulfydryl of volume oxygen metabolism enzyme intracellular combines, and inactivates respiratory enzyme, microorganism is choked to death since respiratory metabolism is blocked.
Nano-titanium dioxide is a kind of semiconductor material for having photo-catalysis function, has very high surface-active, when two
After photon excitation of the titanium oxide by certain energy, it may occur that light-catalyzed reaction simultaneously generates many active matters with strong oxidizing property
Matter (such as hydroxyl radical free radical, superoxipe ion, hydrogen peroxide), these active materials can be interior with microorganism (bacterium, fungi and virus)
Outer organic matter carries out redox reaction and plays the role of antibacterial sterilization to kill microorganism in a short time.
Above two antibacterial agent cooperates by different antibacterial bacteriostatic principles, high-performance is not only greatly improved
The antibacterial sterilization of antimicrobial composite material thought, and had expanded fungicidal spectrum wide, answer the high-performance antibiosis composite material can extensively
For various antibacterial sterilization fields, heat-resisting quantity is strong, and sustained anti-microbial effect is good.Also, nano-titanium dioxide and nano-silver powder tool
There is good dispersion performance, there is excellent compatibility with PPA and E-GMA-MA, with (the dispersing agent 5- of other compositions in formula
15 parts, 0.1~1.5 part of coupling agent) interaction under, these antibacterial agent ingredients and other organic principles are sufficiently mixed and close
It is combined together to form high temperature resistant, high intensity and high performance antimicrobial composite material.
Preferably, the number-average molecular weight of polyphthalamide is heat distortion temperature under 1.5 ten thousand~5.0 ten thousand, 1.80MPa
It (HDT) is 295-300 DEG C.The selection fine heat-resisting performance of this PPA, the good processing stability with E-GMA-MA have excellent
Compatibility can form the composite material of high-toughness high-strength.
