Content be preferably 10-30 parts by weight, more preferably 15-25 parts by weight, more preferably 19-22 parts by weight.
The hydrophilic polypropylene compound provided according to the present invention, HOPP therein can use to be conventional
Various HOPPs, for example, the melt index of the HOPP can be 2-5g/10min.In the present invention, institute
State melt index to refer under 230 DEG C, 2.16kg pressure, the melt index measured according to GB/T 3682-2000 method.
The hydrophilic polypropylene compound contains antioxidant and lubricant.In this case, the antioxidant and
The presence of lubricant can not only play antioxidant and lubricant, but also can synergistically stablize polypropylene mixture
Melt index, and cause there is preferable ageing-resistant performance and outward appearance using polypropylene board prepared by the polypropylene mixture.
In the case that the compound contains antioxidant and lubricant, the weight ratio of the content of the antioxidant and lubricant is preferably
1: 0.1-1, more preferably 1: 0.1-0.5, more preferably 1: 0.3-0.5.
In the present invention, the antioxidant can be various antioxidant commonly used in the art, for example can for four [
Methyl-(3,5- di-t-butyl -4- hydroxy phenyls) propionic acid] pentaerythritol ester, three (2,4- di-tert-butyl-phenyls)
Phosphite ester, β-(3,5- di-t-butyl -4- hydroxy phenyls) propionic acid octadecyl, 1,3,5- tri- (3,5- bis- tertiary fourths
Base -4- hydroxybenzyls) s-triazine, the one or more in 2,4,6- (1H, 3H, 5H) triketones.It is described under preferable case
Antioxidant is four [methyl-(3,5- di-t-butyl -4- hydroxy phenyls) propionic acid] pentaerythritol esters and three (2,4-
Di-tert-butyl-phenyl) phosphite ester mixture, more preferably four [methyl-(3,5- di-t-butyl -4- hydroxy benzenes
