Preparation method.
Background technology
Along with socioeconomic fast development, automobile is indispensable in the lives of the people.Due to modern every day long time
Between stay in automobile, therefore close association between automotive interior air quality and health.Affect in-car air quality
Factor mainly includes two aspects that one is the release of harmful gas in the interior jewelry of automobile itself；Two is the automobile decoration thing that car owner selects
The harmful gas of release.These two aspects is the most all the volatilization of harmful gas in automotive interior trim part, this harmful gas
Mainly volatile organic matter (volatile organic compounds), i.e. VOC is defined as boiling point at 50-by VOC, WHO
Volatile organic matter between 260 DEG C mainly includes formaldehyde, benzene,toluene,xylene, ethylbenzene, styrene etc..Due to empty in automobile
Between narrow and small airtight, in car VOC concentration be far above room air, health is existed potential significant threat.
PP composite material is commonly used for automobile plastic interior trim, needs have preferable heat resistance, flexural fatigue resistance
Energy, cheap price etc..Due to airtight space and sunlit relation in automobile bodies, polypropylene material is especially compound poly-
The volatile organic matter (VOC) that propylene material has in various degree discharges.Therefore, the research and development low VOC of environment-friendly type poly-third
Olefine resin and material can be expanded the application of PP and meet the requirement of green material.
Report currently, with respect to the research of low VOC polypropylene material is more, and they use chemical reaction, physical absorption mostly
And melt devolatilization technology improve VOC in original polypropylene material distribute problem.As patent CN101817953B with the addition of
Odor adsorption agent is prepared for a kind of low modified polypropylene composite material distributed, and odor adsorption agent includes: clay, bentonite, many
Hole silicon dioxide, activated alumina or molecular sieve.But, solve only what VOC produced by controlling raw material sources reduction VOC
One factor, it is impossible to solve VOC material newly generated in the course of processing.And absorption method, either physical absorption or chemistry are inhaled
Attached, all there is the selectivity of absorption and the problem of balance.Chinese patent CN105001525 A is by adding by activated carbon, dividing
At least one in son sieve, zeolite powder and nano inorganic powder (TiO2Or ZnO) adsorbent that is mixed with to reduce abnormal smells from the patient and
VOC, the former be mainly used in absorption, the latter is mainly used in absorption degradation VOC, but the nano inorganic powder of 20-80nm is easily reunited, its
The ability of absorption degradation is just had a greatly reduced quality, and unvarnished, needs competence exertion effect under ultraviolet excitation, therefore, effect
Extremely limited.European patent EP 1988122A1 uses metallocene polypropylene resins to be the automotive trim that matrix resin prepares low VOC
Material.Patent CN101255252B discloses a kind of low-emanation automobile inner fitting special-purpose material, by polypropylene 80-90 part, ultra-fine
Pulvis Talci 10-20 part, low molecule organic matter expellent 1.0-3.0 part, antioxidant 1.0-2.0 part forms.Wherein low molecule is organic
Expellent includes calcium bicarbonate, sodium bicarbonate, magnesium bicarbonate, water, the boiling point fatty alcohol less than 200 DEG C.Its preparation method be by
Low molecule organic matter expellent is successively blended and obtains three grades of vacuum extrudings of the extruded machine of premix material with polypropylene, superfine talcum powder and make
Grain obtains finished product.But, the organic expellent of low molecule that the method is used, wherein carbonate and analyte thereof and polypropylene
There is the problem of the compatibility in resin, and water and boiling point are less than the fatty alcohol of 200 DEG C, owing to its boiling point is relatively low and is leading with premix material
Feeding adds extruder, then there is the persistency with modified polypropylene material melt and homogeneity question.Foregoing invention only pin
Certain factor producing VOC is improved, can not ask at the VOC that raw material and production technology two aspect solve to produce simultaneously
Topic.
On the other hand, polypropylene PP is very easy to burning, and caloric value is big and is easily generated a large amount of molten drop, easily propagating flame,
