Method and device for preparing functional polymer material

Abstract

The invention relates to a preparation method of a functional polymer material, which comprises the following steps: dissolving a substance containing functional particles to obtain a functional particle solution; atomizing the functional particle solution to form functional particle gas in a mist state; heating the functional particle gas in the mist state to remove water vapor; the heated gas passes through a negative electrode net after being cooled, so that the functional particles are negatively charged; the functional particles with negative charges enter an accelerating electric field to be accelerated, and then impact and are embedded into the softened surface of the polymer base material; by applying the method provided by the invention, the functional macromolecular substance is dissolved, atomized, subjected to water vapor removal and charged, then impacted in an accelerated manner and embedded into the softened macromolecular substrate surface, the whole set of operation can be completed, the operation is very simple, and the utilization rate of functional molecules is high; meanwhile, in the early stage, force generated by atomization assists functional particles in moving, removing water vapor and entering an electric field, the overall arrangement is reasonable and compact, the size is small, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of functional polymer materials, and more specifically, relates to a preparation method and device for functional polymer materials. Background technique [0002] At present, there are mainly two methods for preparing functional materials: blending modification and surface chemical grafting modification. The former method is likely to cause functional substances to be embedded in the polymer material, making it difficult to exert functional effects, while the latter method has The defects of complex preparation process, low controllability and poor applicability; [0003] A method and device for preparing functional polymer materials with simple processing, good applicability and low cost are needed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for preparing a functional polymer material and a device for preparing a functional polyme...
