Taste agent that what the present invention was used dispel, is by high-purity solvent, aerosil and styrene block copolymer group
Into pre-composition.The high-purity solvent of higher amount can effectively be adsorbed using the larger specific surface area of aerosil, adsorbed
Intensity is higher；The solvent of high level, is effectively reduced melt polypropylene surface tension, removes VOC cleaner；Adsorption strength
Higher, the solvent desorption that is heated uniformly slowly discharges, and reduces partial pressure, can be avoided the solvent that conventional method occurs be heated it is i.e. fast
The problems such as steam stripping efficiency declines, has high demands on extruder exhaust capacity, affects extruder working (machining) efficiency caused by speed volatilization release.
Aerosil containing two kinds of surface textures in taste agent that what the present invention was used dispel, on the one hand fills in taste agent of dispelling
When the adsorbent of absorption high-purity solvent, more solvents can be absorbed；On the other hand the molten of absorption is discharged in melting process
The VOC of generation can effectively be adsorbed after agent again；Simultaneously using its surface active group silicone hydroxyl functional group and aldoketones it is little
Molecular compound forms interaction of hydrogen bond, effectively adsorbs aldoketones, effectively suppresses aldoketones VOC.Therefore reduce polypropylene tree
The rate of release of oil/fat composition VOC, delays or prevents the discharge of VOC in polypropylene.
The styrene block copolymer contained in taste agent that what the present invention was used dispel, the compatibility pole with acrylic resin
It is good, dispersion effect of the aerosil in PP composite material can be effectively improved, the suction of aerosil is improved
Attached efficiency, significantly reduces VOC release contents in polypropylene.
The total volatile organism (TVOC) of the PP composite material of the present invention can be significantly reduced, and more preferably, TVOC can
Less than 40 μ gC/g, to solve the deficiencies in the prior art well, operating procedure is simple and reliable, and input cost is relatively low, it is adaptable to
The fields such as higher superior automobile inside gadget, medical and packaging material for food.
Specific embodiment
