Abstract

The invention discloses an elastic shape memory material with a repeated self-repairing function and a preparation method thereof. The elastic shape memory material with the repeated self-repairing function comprises the following components in parts by volume: 60-85 parts of silicon rubber and 15-40 parts of hot melt glue. The preparation method comprises the following steps of: firstly, cuttinga hot melt glue stick into small blocks and mixing the hot melt glue blocks and liquid silicon rubber elastomers according to the proportion; heating a mixture to above the melting point of the hot melt glue, and sufficiently stirring until no macroscopic particles exist in the mixture; after the mixture is cooled to the room temperature, mixing the silicon rubber elastomers and a curing agent ina proportion of (5-15): (0.5-1.5), then curing, and uniformly stirring again; pouring the sufficiently mixed mixture into a mould, and placing the mixture into a vacuum drying oven with the vacuum degree of 1Pa to remove air bubbles in the mixture; curing the mixture at room temperature for 24h; or curing at 100 DEG C for 1h; or curing at 150 DEG C for 15min to obtain the required finished product.

Description

technical field

[0001] The invention relates to a shape memory material, in particular to an elastic shape memory material with multiple rapid self-repair functions and a preparation method thereof. Background technique

[0002] After quasi-plastic deformation, shape memory materials (including some alloys and polymer materials, etc.) can return to their original shape under appropriate stimulation. This phenomenon is called the shape memory effect. The main factors affecting the recovery of shape memory alloys are temperature or magnetic field, and for shape memory polymers, in addition to temperature and magnetic field, it also includes light and humidity, etc., usually polymer materials with shape memory function, only in their shape memory When the transition temperature is above, the material is in an elastic state and has a certain degree of elasticity.

[0003] Although different types of shape memory materials have different mechanism of shape memory effect, in the ...
