Description
Technical field
The present invention relates to material modified technical field, and in particular to a kind of low smell, high impact resistance polypropylene composition and its
Preparation method.
Background technology
Polypropylene (PP) material extensively should be obtained due to its good combination property in the major assembly systems of automobile
With.Automobile exterior trimming parts use PP composite material injection molding mostly with inside gadget.Exterior trimming parts such as bumper, threshold, shirt rim
Deng automotive upholstery such as instrument board, column, glove compartment, door-plate etc..Because simple polypropylene is difficult to meet each parts of automobile
Performance requirement be modified, it is necessary to add talcum powder, glass, toughener, antioxidant and damage resistant agent etc., to meet its machine
Tool performance and long-term anti-ageing performance.But the addition of these materials, volatile materials can be produced in process, these things
Matter is the main source of smell, especially interior material, if smell is very big, can have a strong impact on the air quality of in-car, influence
Member's is healthy by bus, therefore the country is put into effect《Air Quality Evaluation guide in passenger car》, improve in-car air quality and compel
It is also the important topic of current all vehicle inside decoration investigations of materials in the eyebrows and eyelashes.
By adding BX molecular sieves and activated alumina in patent No. CN101314658A, by a large amount of present in molecule
Hole, the size according to crystals hole carries out the absorption of selectivity to small-molecule substance so as to reach the improvement to smell,
But the shortcoming of the invention is can not to adsorb smell small-molecule substance completely, and due to being physical absorption, adsorbed smell is small
Molecular substance can discharge again, therefore this method can only reduce the short-term smell of material, and effect is very unstable.
By adding response type castor oil in patent No. CN103524872A, material is chelated by the active group in castor oil
Ammonia, sulphur class, thio-alcohol scent molecule in material, because this method is to chelate specific smell small molecule by chemistry, therefore
The smell small-molecule substance that can not be reacted can not be dispelled, it is impossible to thoroughly improve the smell of material.
By adding jellyfish grain in patent No. CN103724799A, vacuumized when being extruded by high temperature, by the water in jellyfish
Extraction exclusion is carried out to smell small-molecule substance by vapor, reaching improves the purpose of material smell, but prepare jellyfish grain
Complex process, jellyfish grain in moisture content it is very unstable, due to water 100 DEG C gasification, it is difficult to ensure that smell small molecule thing
Matter is extracted completely, and smell improvement is unstable.
The content of the invention
It is an object of the invention to provide a kind of low smell, high impact resistance polypropylene composition and preparation method thereof.
The technical solution used in the present invention is：
It is made up of the raw material of following mass parts：55-70 parts of polypropylene, 10-20 parts of impact modifier polyolefin bullet
Property body, 15-25 parts of talcum powder, 0.1-0.5 parts of antioxidant, 0.5~1.0 part of smell extractant, the extraction of 0.5~1.0 part of smell
Synergist.
Preferably, described smell extractant is Ca (HCO3)2、KHCO3And/or NaHCO3, it is more preferably a kind of scentless
NaHCO3, the smell small-molecule substance in a large amount of gases, fiber material is produced when being processed by extruding, to reduce material smell etc.
Level.
Preferably, described smell extraction synergist is one kind in tartaric acid, food acids, preferred a kind of scentless
Citric acid, by with smell extractant NaHCO3Synergistic, improves the stability that gas is produced in its process, improves smell small
The effect of molecular substance extraction, preferably reduces material smell.
Preferably, the polypropylene is mixture more than one or both of homopolymerization and/or copolymerization PP, its melt flow
Dynamic speed is 20~80g/10min under the conditions of 230 DEG C, 2.16kg, and preferred melt flow rate (MFR) is 40~80g/
10min, the shearing that the polypropylene of height flowing is subject in extrusion processing and processing and forming is small, so as to reduce small point of smell as far as possible
The generation of sub- material.
Preferably, impact modifier polyolefin elastomer be ethylene-butene copolymer and/or ethylene-octene copolymer, it is close
Spend for 0.850-0.890g/cm3, its melt flow rate (MFR) is 0.5~2.0g/10min under the conditions of 190 DEG C, 2.16kg
Preferably, described antioxidant is 1010,168.
A kind of low smell, the preparation method of high impact resistance polypropylene composition, comprise the following steps：
According to mass fraction than weigh respectively 55-70 parts polypropylene, 10-20 parts of impact modifier polyolefin elastic
Body, 15-25 part talcum powder, 0.1-0.5 parts of antioxidant, 0.5~1.0 part of smell extractant, 0.5~1.0 part of smell extraction association
Imitate agent to be well mixed, knead, extrude by double screw extruder.
Preferably, the technological parameter of double screw extruder is：1 170~190 DEG C of area, 2 180~210 DEG C of areas, 3 areas 180~
210 DEG C, 4 180~210 DEG C of areas, 5 180~210 DEG C of areas, 6 180~210 DEG C of areas, 7 180~210 DEG C of areas, 8 210~230 DEG C of areas, 9
210~250 DEG C of area, 10 210~250 DEG C of areas, 200~230 DEG C of head temperature, head pressure 3.8Mpa, main frame electric current 30Hz, very
Reciprocal of duty cycle -0.08MPa.
Compared with prior art, the present invention has the advantages that：
Adding the methods such as molecular sieve/activated alumina, active castor oil, jellyfish grain with prior art improves material smell,
This law effectively avoids unstable, the active castor oil that molecular sieve/activated alumina adsorbs to small molecule can only be small to smell
The complex process and smell of the selective absorbing of molecule and addition jellyfish grain it is unstable.The present invention is extracted by adding smell
Take agent NaHCO3, NaHCO in extrusion3Decompose and produce a large amount of scentless carbon dioxide and water, it is small to smell by vacuumizing
Molecular substance carries out extraction exclusion, due to NaHCO3Decomposition temperature be 110~150 DEG C, processing temperature is narrower, is individually added into
NaHCO3It is limited to smell effect of extracting, and citric acid can not directly produce gas, but adding citric acid can improve
NaHCO3Decomposition temperature to 150~230 DEG C, therefore the smell small molecule produced under high temperature can effectively be extracted, together
When further reduce the smell of material.
