Condensation material and preparation method thereof.
Background technology
Polypropylene as one of five big general-purpose plastics, because with nontoxic, light weight, inexpensive, chemical resistance and good
Physical Processing performance is widely used in the fields such as building, traffic, automobile, household electrical appliances, and the most fast consumption of growth rate at present
A kind of larger general plastic.But polypropylene also has mechanical strength, and the poor, heat resistance of high and low temperature impact is not bad, easy
Aging the shortcomings of, it usually needs process is modified in itself to polypropylene or day addition auxiliary agent is improved performance to be modified and come
Meet multiple demand growing to polypropylene material during people live.
Polypropylene as a kind of high-molecular organic material, its product storage and it is thin using being contaminated and become some
The breeding ground of the harmful microorganism matter such as bacterium, funguses, so can have adverse effect on to the health of contactee, due to polypropylene sheet
Body does not have antibiotic property, and the presence of these bacterium colonies can have a strong impact on the outward appearance of material, while under the performance of material can also occurred
Drop, therefore the necessary anti-microbial property for going to improve polypropylene material；Antibacterial is generally divided into inorganic, organic and natural three big
Class, inorganic antiseptic typically contain the materials such as metal ion silver, titanium, zinc, copper, in the market with inorganic antiseptic with silver system
Usage amount it is maximum, inorganic antiseptic has heat-resisting safety durability preferably, but which also has poor with polymer-polymer miscibility, anti-
The shortcomings of bacterium late effect property；Organic antibacterial agent mainly includes phenyl aminess, quaternary ammonium salt, phenols, guanidinesalt class etc..With inorganic antiseptic phase
Than organic antibacterial agent can quickly kill antibacterial like that, and organic antibacterial agent is with the matrix resin compatibility preferably, in the course of processing
Middle operability is also good than inorganic antibacterial property；The shortcomings of but organic antibacterial agent thermostability is poor, effect duration is short.Consider,
The present invention improves the resistance to of PP composite material using a kind of heat-resisting complex antimicrobials of new organic-inorganic doping mixing
Hot anti-microbial property, the antibacterial can simultaneously containing the compatibility of organic system, the safety of prompt effect and inorganic system, thermostability, hold
Long property.
Polypropylene is used as a kind of plastics, it is clear that be extremely incendive, its product has certain uneasiness in daily use
Total factor, generally requires addition fire retardant and improves the polypropylene material that can just make of fire resistance of polypropylene material in electronics device
The applications such as material, household electrical appliance, automobile are not limited；It is easy that traditional halogen containing flame-retardant occurs some because of release during burning
Carcinogenic material, some developed countries and area are halogen to part fire-retardant to implement ban.Common halogen-free flame retardants bag
Include phosphorus-nitrogen containing flame retardant, the such as organic phosphorous heterocylic compound of phosphate ester, red phosphorus, tripolycyanamide etc.；Inorganic hydroxide, such as hydroxide
Magnesium, aluminium hydroxide etc.；Silicon-series five-retardant, such as polysiloxanes, silicate etc..
In order to improve fire-retardant, the heat-resisting and anti-microbial property of PP composite material, in PP composite material preparation process
It is middle to add a kind of heat-resisting complex antimicrobials of new organic-inorganic doping mixing to improve the heat-resistant of PP composite material
Bacterium performance；Add a kind of new silsesquioxane type halogen-free flame retardants to put forward the fire resistance of PP composite material simultaneously.
Wherein high temperature resistant complex antimicrobials main component is guanidine salt polymer and nano titanium oxide, and guanidine salt polymer is used as a kind of high
Effect, non-stimulated, harmless to person antibacterial agent are widely used in the fields such as fiber, plastics, rubber, nano titanium oxide
There is the features such as nontoxic, non-stimulated, stability is strong as a kind of common inorganic antiseptic, while titanium dioxide adds as inorganic
Plus thing itself has good thermostability, is used in combination with organic antibacterial agent, can play synergism well；Silsesquioxane
Have that consumption is few, thermal discharge is few as a kind of new and effective fire retardant, and polymer compatibility it is good the features such as.
