Abstract

This invention relates to a functional polyolefin long time effective flow film and its preparation method, which applies the polyether tetra-basic alcohol to be reacted with maleic anhydride or crylic acid to get functional monomers, pre-radiates the polyolefin resin with beta or gamma rays, then carries out smelt graft reaction to the processed polyolefin resin, the functional monomers and electron donating reagent then to blow-molding the graft product to a functional polyolefin long time effective flow film and the valid time is 25-45 days and 13-16 months.

Description

technical field

[0001] The invention relates to a functionalized polyolefin long-lasting dripping membrane and a preparation method thereof. Background technique

[0002] Polyethylene, ethylene-1-butene copolymer, ethylene-1-hexene copolymer, ethylene-1-octene copolymer, ethylene-vinyl acetate copolymer, polypropylene, and poly1-butene have good comprehensive properties The low-cost general-purpose polymer materials, but because of their non-polar characteristics to a certain extent, limit the expansion of their application range. The method of reactive extrusion is used to graft monomer molecules containing polar groups into the polymer. By using the polarity and reactivity of the polar group on the molecular chain of the object, many new properties can be given to the polymer material, such as cohesiveness, hydrophilicity, dyeability, aging resistance, antistatic property, etc.

[0003] The non-polar polyolefin film has poor hydrophilicity, and a layer of white water drop...
