Abstract

The invention discloses a preparation method of a polyimide film with high orientation stability. The polyimide film with high orientation stability is prepared from the following raw materials in parts by mass: 91-93 parts of polymerized polyamide acid resin, 4-6 parts of an elasticity enhancing ingredient, 3-5 parts of graphene, 0.2-0.3 part of a silane coupling agent, 0.5-1 part of non-conjugated diene, 0.5-1 part of a dimethyl acetamide solvent, 5-9 parts of an ingredient A and 3-5.5 parts of a stability enhancing ingredient. By adding materials such as artificial elastic fibers, polyether ester elastic fibers, polyolefin elastic fibers and polybutadiene, when the polyimide film is used, not only is the stability improved, but also the elastic performance and the wear resistance are greatly improved.

Description

technical field [0001] The invention relates to the field of pure natural compositions with the function of reducing fat and losing weight, in particular to a preparation method of a polyimide film with high orientation stability. Background technique [0002] Polycondensation type aromatic polyimide is prepared by reacting aromatic diamine with aromatic dianhydride, aromatic tetracarboxylic acid or aromatic tetracarboxylic acid dialkyl ester. Since the synthesis reaction of polycondensation polyimide is carried out in high-boiling aprotic polar solvents such as dimethylformamide and N-methylpyrrolidone, polyimide composites are usually made of prepregs Molding process, these high-boiling aprotic polar solvents are difficult to volatilize during the preparation of prepregs, and volatiles are also released during the cyclization of polyamic acid, which is easy to produce pores in composite products, which is difficult High-quality, void-free composites are obtained.
