With.
Background technique
Polypropylene has many advantages, such as that density is low, mechanical performance is excellent, endurance surrenders, is cheap, is widely used
In fields such as automobile, household electrical appliances, food packagings.Wherein, heat-resisting old required for interior trim product to meet in automobile interior decoration field
Change, light aging resisting, scratch resistance and processability requirement, need to add a certain amount of antioxidant, light in polypropylene matrix steady
Determine the function additives such as agent, damage resistant agent, processing aid and carries out functional modification.
Polypropylene material is polymerized by propylene monomer, is not contained polar group, is belonged to non-polar material；And it is usual
The function additives such as antioxidant usually all contain polar group, belong to polar material.According to similar compatibility principle, the two compatibility
Difference, simultaneously because this analog assistant belongs to small molecule substance, in the use process accumulated over a long period, in light heating condition
Under, these small-molecule substances can have the case where moving to article surface in material, cause piece surface aggregation to show
Tacky phenomenon influences the beauty and feel of interior material, be easy to cause the complaint of consumer.
The tackiness method of the common precipitation for improving polypropylene material includes: a. to add the compatilizer of polar functionalities
(CN 104558841A), b. use low Polar adjuvants (CN200910197584.5) instead, c. uses the biggish auxiliary agent (CN of molecular weight instead
106147027 A).Three kinds of methods are tacky for reduction precipitation to suffer from certain effect, but there is also clearly disadvantageous.Add
Adding the defect of the compatilizer of polar functionalities is: compatilizer can promote being uniformly dispersed for polar functionalities auxiliary agent, but will lead to
In the case where identical additive amount, the auxiliary agent content dispersed on the surface of the material reduces and influences corresponding function (such as damage resistant
Agent influences whether damage resistant function in surface concentrations reduction), if polypropylene material may be influenced whether by increasing auxiliary agent totality additive amount
Other performances of material, but also cost obviously increases；The defect for using low Polar adjuvants instead is: having some limitations, first
Low polarity is only reduction of its own polarity, and has not been fully converted to nonpolarity, therefore only delays tacky generation
Time and not eradicated, secondly and not all auxiliary agent classification can find corresponding low polarity substitute, so
It is not particularly suited for all PP composite material systems；The defect for using the biggish auxiliary agent of molecular weight instead is: since molecular weight is larger,
Cause to be easy to reunite in the base, influences the using effect of itself, the area that field of flow changes especially in product forming process
Domain is easier to occur reuniting to lead to the open defects such as piece surface floating.
In conclusion existing solution polypropylene material is precipitated tackiness method and has limitation.
