Description
Technical field
The present invention relates to a kind of functionalized polypropylene material and preparation method thereof more particularly to a kind of antibacterial, low distribute
Modified polypropylene composite material and preparation method thereof belongs to polypropylene technology field.
Background technique
With the rapid development of new-energy automobile, automotive light weight technology, safe and interior comfortableization, environmental protection are proposed
Higher requirement.Modified polypropene as auto parts common used material, have from a wealth of sources, density is small, mechanics it is harmonious it is good,
Resistant to chemical etching, easy processing and it is cheap outstanding advantages of.
But polypropylene material for automobile interiors inevitably generates in the techniques such as synthesis, modification, injection molding and largely may be used
It volatilizees small organic molecule, and environment inside car is relatively closed, this will lead to interior organic matter, and to distribute substance content exceeded, thus
Influence the health of passenger inside the vehicle；Meanwhile to will also result in in-car smell poor for acrylic resin degradation and the addition of auxiliary agent, influences
The comfort of passenger.It is big it is equal (development [J] engineering plastics application of the low VOC fiber glass reinforced polypropylene material of low smell, 2017,
45 (1): 35-38.) achieve the purpose that improve smell by adding odor adsorption functional agglomerate, the results showed that odor adsorption agent has
Improving material smell and reducing organic matter for effect distributes, but it is expensive, and sexual valence is relatively low, and additional amount can excessively be led
Cause the decline of modified polypropylene material mechanical property；CN107619537A report carries out organic matter by addition nano-titanium dioxide
Degradation, but its office shows property and is that ultraviolet light is needed to be caused.Therefore, low poly- third is distributed for novel, high performance-price ratio
The exploitation of alkene is still extremely urgent, and wherein porous structure inorganic matter addition reduction polypropylene, which distributes, attracts much attention.
In addition, the development of new-energy automobile has also driven the rapid development of Car sharing, consumer is for using shared vehicle
Healthy and safe requirement it is also more next harsh.It is well known that modified polypropylene plastic under the conditions of suitable temperature and humidity, is made
Product surface can largely generate the microorganisms such as bacterium, be detrimental to health, this strongly limits polypropylene automotive field application.
It is currently reported that nano-TiO is added in polypropylene2, can inhibit bacterial growth under conditions of ultraviolet light, it is net to reach air
The effect of change, antibacterial, self-cleaning.Its Antibacterial Mechanism be nano-titanium dioxide generated after ultraviolet excitation active super oxygen from
Sub- free radical and hydroxyl radical free radical can penetrate the cell wall of bacterium, destroy cellulose into thallus and prevent the biography of film forming matter
It is defeated, its respiratory system and electron-transport system are blocked, so that effectively killing bacterial decomposition organic matter generates stink substances (such as
H2S and NH3Deng).But the high-efficiency antimicrobial of titanium dioxide is to be used for causing certain limitation by ultraviolet excitation
Property.And nano zine oxide as it is a kind of by itself generate active oxygen carry out antibacterial inorganic powder, it is easier to imparting polypropylene
Efficient antibacterial characteristics.

Alkene composite material and preparation method, mainly by by the nano zine oxide of novel porous silicic acid calcium particle and high-efficiency antimicrobial
It is cut after circulating water into pelleter with conventional polypropylene by twin-screw or injection molding machine blending extrusion strip blend
Grain obtains modified polypropene particle.Wherein Nano zinc dioxide impact-resistant due to its be also easy to produce active oxygen impart modified polypropene efficiently and
Long-acting antibacterial ability；Porous calcium silicate has uniform particle sizes and chemical stabilization as a kind of New Mineral additive simultaneously
Characteristic imparts the good comprehensive mechanical property of modified polypropene, and specifically, efficient absorption ability effectively adsorbs extrusion
Small-molecule substance and bad smell that degradation of polypropylene generates in the process, assign its low smell, low VOC characteristic.
