Abstract

The invention relates to the technical field of plastics and discloses a synthetic method of polyimide foamed plastics. The synthetic method is characterized in that PPMA (Polymethyl Methacrylate), polylactic acid, polylactone, polystyrene and the like are reasonably fused into a molecular main chain of polyimide, and a fused matter is gradually decomposed to form polyimide foams at a high temperature state.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a synthesis method of polyimide foam plastics. Background technique [0002] Synthetic plastic foams are too inefficient in the prior art. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a method for efficiently preparing foamed plastics. [0004] Technical scheme of the present invention is: [0005] The synthetic method of polyimide foam is characterized in that: PMMA (polymethyl methacrylate) and polylactic acid, polylactone and polystyrene etc. are incorporated into the molecular main chain of polyimide reasonably, in At high temperature, it gradually decomposes to form polyimide foam 。 This synthesis method can effectively control the distribution and size of plastic pores, and effectively reduce the dielectric constant on the basis of maintaining the mechanical and thermal properties of the plastic. [0006] The ...
