Embodiment Construction

[0022] A preparation method of surface anti-sticking shape memory epoxy resin, is characterized in that, comprises the following steps:

[0023] (1) Preparation of silk protein solution

[0024] After the silk protein raw material is degummed, it is then washed and dried, dissolved in sodium hydroxide solution, fully hydrolyzed to obtain a silk protein solution, concentrated and then subjected to a dialysis process to obtain a silk protein solution, adding sodium azide, and mixing evenly. stand-by;

[0025] (2) Preparation of modified gellan gum solution

[0026] a) Add gellan gum powder into deionized water at room temperature, swell at room temperature, and perform magnetic stirring at 70-90°C until the gellan gum powder is completely dissolved to form a transparent and clear solution;

[0027] b) mixing the gum arabic and the crosslinking agent in parts by weight to obtain a mixture;

[0028] c) After mixing the product of a) and b), adding the fibroin solution obtained ...

Abstract

The invention discloses a preparation method of surface anti-sticking shape memory epoxy resin. The preparation method comprises the following steps: degumming, dissolving, concentrating and dialyzingfibroin; adding sodium azide and then dissolving gellan gum powder; mixing and dissolving Arabic gum and a crosslinking agent and mixing a previous solution with a later solution; adding a fibroin solution, heating and then adding liquefied epoxy resin into the solution, adding mixtures such as kaolin and sufficiently and uniformly stirring; and adding a curing agent, injecting the curing agent into a die, curing and cooling to obtain the surface anti-sticking shape memory epoxy resin. According to the preparation method disclosed by the invention, the gellan gum is modified and then the liquefied epoxy resin is added to obtain the surface anti-sticking shape memory epoxy resin. The surface anti-sticking shape memory epoxy resin has a shape memory effect, is improved in elasticity and theflexibility, has a dry, clean and smooth surface and realizes an anti-sticking effect.

Description

technical field [0001] The invention belongs to the technical field of resin processing, and in particular relates to a preparation method of surface anti-adhesive shape memory epoxy resin. Background technique [0002] The research on shape memory polymers is mainly shape memory thermoplastic polymers, represented by polyurethane. However, many engineering material systems are thermosetting, which have high requirements for mechanical properties, heat resistance and environmental resistance, and are also poorly compatible with thermoplastic systems. Therefore, research on thermosetting shape memory resins, mainly shape memory epoxy resins, began in the late 1990s. Contents of the invention [0003] The invention provides a method for preparing a surface anti-adhesive shape memory epoxy resin. In the present invention, gellan gum is modified, and liquid epoxy resin is added to prepare a surface anti-adhesive shape memory epoxy resin, which has a shape memory effect. The ...
