Miberal powder can select existing conventional all kinds, but in order to further improve the compatibility between each material, and then
Improve products obtained therefrom combination property, it is preferable that the miberal powder be talcum powder, calcium carbonate, mica or ester exchange at phosphorus at least
It is a kind of.
In order to further improve the scraping and wiping resistance performance of product, the maleic anhydride grafted elastomeric is that maleic anhydride grafting is low
Density polyethylene (MAH-g-LDPE), maleic anhydride grafted ethene propylene elastomeric (MAH-g-EPR), maleic anhydride grafted ethene
In acrylonitrile-butadiene elastomer (MAH-g-EPDM) or maleic anhydride grafted ethene octene elastomer (MAH-g-POE) at least one
Kind.
In order to further improve the combination property of product, especially scraping and wiping resistance performance, it is preferable that the slaine is metal oxygen
At least one in compound, metal halide, metal acetate salt or metallic stearate.Further preferably, the slaine is
At least one in zinc oxide, zinc stearate, zinc chloride or zinc acetate.
Antioxidant can be various antioxidant commonly used in the art, such as can be that aromatic amine antioxidant or Hinered phenols are anti-
Oxygen agent etc., but in order to be able to the cooperative effect between other each components is performed to most preferably, the antioxidant be antioxidant 1010 or
At least one in irgasfos 168.
In order to further improve the compatibility between each material, make the cooperative effect between each component perform to most preferably, from
And the combination property of product is preferably ensured, it is preferable that the lubricant is Tissuemat E.
The preparation method from aggressiveness modified polypropylene composite material of above-mentioned reaction in-situ generation, including it is connected in order as
Lower step：
A, by acrylic resin, miberal powder, maleic anhydride grafted elastomeric, antioxidant and lubricant add banbury in,
Banburying 3-8 minutes at a temperature of 160-200 DEG C；
B, slaine adds above-mentioned banbury, at a temperature of 180-220 DEG C with step a resulting material banburyings 3-8 points
