The sealable chest of shapes and sizes identical is made in the plastics that embodiment 1 and the preparation of comparative example 2 is respectively adopted, will
Decibel instrument is individually positioned in two chests, and decibel instrument in the sound of identical decibel, two chests of statistics is sent outside chest and is surveyed
The decibel result of examination, as a result shows the decibel instrument test placed in the salable chest that the plastics prepared using embodiment 1 are made
To sound decibel be only the decibel instrument test placed in the salable chest that is made of plastics prepared by comparative example 2 sound decibel
1/2, it can be seen that, by adding in the feed using pomace and stalk fibre in the present invention, with resin, starch, solubilising
Agent and coupling agent etc. act synergistically, the soundproof effect of reinforced plastics.
2nd, anti-microbial property contrast test：
Test method：It is divided to two groups of experiments, takes staphylococcus aureus and Escherichia coli to be coated on M-H trainings in every group of experiment
Base is supported, environment-friendly antibacterial sound insulation plastics prepared by one of which Example 1 are affixed on media surface, and another set takes comparative example 1
The automobile interior exterior decorations of preparation are affixed on media surface with plastics, are then respectively placed in 37 DEG C of constant incubators and are cultivated, 48 is small
When after observe result, plastics prepared by Statistics Implementation example 1 and comparative example 1 are imitated to the antibacterial of staphylococcus aureus and Escherichia coli
Really, as a result show, plastics prepared by embodiment 1 reach 90% to the antibiotic rate of staphylococcus aureus, to the antibacterial of Escherichia coli
Rate reaches 95%；And plastics prepared by comparative example 1 are only 70% to the antibiotic rate of staphylococcus aureus, to the antibacterial of Escherichia coli
Rate is only 78%.
Existed by the results showed that present invention by combining and adhering to absorption by Nano chitosan and nano titanium oxide
The mode of frosting, and optimize the proportioning of nano titanium oxide different crystal forms simultaneously, improve the anti-microbial property of plastics.
3rd, anti-fouling and self-cleaning performance contrast test：
Test method：The plastics that respectively prepared by Example 1 and comparative example 1, soy sauce is sprayed on its surface respectively, places 30
After minute, wiped with rag, observe the cleaning situation of two kinds of frosting dirts, as a result show, the frosting of embodiment 1
The soy sauce of sprinkling can be wiped out easily after placing 30 minutes with rag, will not be adhered in frosting, and comparative example 1 is moulded
Expect the soy sauce of surface sprinkling after mode 30 minutes in immersion plastics, it is difficult to remove, it is necessary to by special cleaning products ability
Remove.The reason is that prepared by the embodiment of the present invention 1, plastics are combined in frosting and attachment nano titanium oxide causes for analysis
The hydrophilicity that frosting has had so that the pollutant such as greasy dirt is difficult to be attached to its surface, making the plastics of preparation has one
Fixed anti-fouling and self-cleaning performance.
4th, air cleaning performance comparison test：
Test method：It is divided to two groups of experiments, takes the unit of plastic of 30 pieces of 10cm × 10cm sizes to be suspended on UV in every group of experiment
In ultraviolet radiation reaction chamber, the beaker that will be equipped with formalin is also placed in reaction chamber, seals reaction chamber, treats formaldehyde volatilization one
The section time, make that there is certain density formaldehyde gas in the air of reaction chamber, then take out beaker, seal reaction chamber, open
UV lamp is irradiated, and the concentration of formaldehyde in each certain time reaction chamber is measured using the small-sized Formaldehyde analyzer of digital mobile,
Plastics prepared by embodiment 1 are hung in one of which experiment in reaction chamber, and comparative example 1 is hung in another set experiment in reaction chamber
The plastics of preparation, pass through in the course of reaction of different time, the Photocatalytic Degradation Property of plastics PARA FORMALDEHYDE PRILLS(91,95) in two groups of experiments of statistics,
As a result show：
Plastics prepared by embodiment 1 are after UV irradiates 2 hours, and the concentration of formaldehyde in reaction chamber is reduced behind 80%, 6 hours,
Concentration of formaldehyde is reduced to 0.8ppm, and plastics prepared by comparative example 1 are after UV irradiates 2 hours, and the concentration of formaldehyde in reaction chamber is only
Reduce behind 10%, 6 hours, concentration of formaldehyde also reduced by only 50%.The reason for analyzing the result of the test be, the embodiment of the present invention
1 plastics prepared compare comparative example 1, by nano titanium oxide being combined and adsorbing on the surface of plastics, play nano-silica
Change titanium has the function of absorption and photocatalytic degradation volatile organic matter in itself, the organic dirt for the in-car volatilization that on the one hand can degrade
Thing is contaminated, the organic matter that plastics are volatilized in itself on the other hand can be fundamentally prevented into the car, the work of purification air is realized
With.
5th, the mechanical performance of the plastics prepared respectively to embodiment 1 ~ 3, burning grade and environmental protection index are tested, as a result
It has been shown that, its tensile strength average out to 22MPa；Hardness average out to 55HRC；Elongation at break average out to 700%；Break permanent deformation
Average out to 17%；Flame retardant rating V0；The μ g/g of formaldehyde ＜ 3mg/kg, TVOC ＜ 10 μ g, toluene ＜ 1 μ g/g, dimethylbenzene ＜ 5, fog examination
＜ 0.5mg are tested, odor test is 1 grade, reaches environmental-protecting performance requirement.
