Abstract

The invention discloses a water stimulation response rubber composite material and a preparation method thereof. The rubber composite material comprises the following raw materials in parts by weight:30-80 parts of nitrile rubber, 20-70 parts of polyethylene oxide, 0.8-1.6 parts of a vulcanizing agent and 0-5 parts of a processing aid. The invention further discloses a preparation method of the rubber composite material. The rubber composite material is prepared from the raw materials through mixing and vulcanization. A conventional rubber high polymer material and a functional high polymer material are compounded to prepare the rubber composite material with water stimulation response through mixing and vulcanization, the rubber composite material is a novel stimulation response rubber composite material, the utilization value of a shape memory high polymer material can be increased, the rubber composite material has a uniform texture, is of a cross-linked network structure, is freeof problems such as delamination, has a transition temperature interval between room temperature and body temperature constantly, has good properties of shape memory fixation and shape recovery, and can be widely applied to fields such as biological medical treatment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a water-stimuli-responsive rubber composite material and a preparation method thereof. Background technique [0002] Shape-memory polymer material is a kind of product with an initial shape that changes its initial condition and fixes it under certain conditions, and can restore its original shape through the stimulation of external conditions (such as heat, electricity, light, chemical induction, etc.). Polymer Materials. Shape memory polymer materials have a large amount of deformation, easy to assign, light weight, and structural diversity; and have excellent insulation properties, heat preservation properties, and easy coloring properties, making them widely used in biomedical, smart textiles, and high-performance sensors. focus on. Shape memory polymer materials have great application prospects in the field of clinical medicine and implanted medical equipment. W...
