Abstract

The invention discloses a modified polyvinyl chloride composite film and a preparation method thereof. The modified polyvinyl chloride composite film comprises, by mass, 35-60% of polyvinyl chloride, 15-20% of polyvinyl alcohol, 10-15% of polyvinylpyrrolidone, 2-8% of erucamide, 5-10% of ethylene-octylene copolymer grafted maleic anhydride, 2-5% of nanometer silica, 1-3% of polyethylene glycol alkyl ether, 1-2% of a light stabilizer 944, 1-2% of silicone powder and 0.5-1% of fatty alcohol polyoxyethylene ether. The modified polyvinyl chloride composite film has the advantages of good slip effect, excellent antistatic performance, good heat and weather resistance, good impact toughness, good tensile strength, high elongation at break, good molding, and simple preparation process.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride composite film, in particular to a modified polyvinyl chloride composite film and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a thermoplastic material with low cost and excellent processability, which can be used to prepare film composite materials for packaging. Polyvinyl chloride film material is exactly a kind of film material that uses very widely, but polyvinyl chloride of prior art forms polyvinyl chloride base film material through stretching molding and has low elongation at break, and its tensile property is also relatively low. Poor, not suitable for applications with high elasticity requirements. Therefore, it is necessary to improve the necessary performance of the existing polyvinyl chloride film to improve its tensile properties and elongation at break, so as to better expand its application field. Contents of the invention [0003...
