Embodiment 1
[0028] Such as figure 1 , the present embodiment provides a preparation method of gamma-ray radiation-resistant shape-memory cyanate resin material, comprising the following steps:
[0029] The first step: put the cyanate monomer with a mass fraction of 50%-80% in an oil bath at a temperature of 100-120°C, and after the cyanate monomer is completely dissolved, add a mass fraction of 10 %-20% plasticizer and 10%-30% cross-linking agent by mass fraction, magnetically stirred for 30-60min to prepare a uniform cyanate precursor solution, wherein the cyanate is bisphenol A type cyanate; the plasticizer is one or more of epoxy resin, polycaprolactone, polyol ester; the cross-linking agent is polyethylene oxide, diethylene glycol divinyl One or more of ether and polyethylene glycol;
[0030] The second step: inject the cyanate ester precursor solution prepared in the first step into the preheated mold at a preheating temperature of 90-120°C, and place it in a blast oven at a temper...
Embodiment 2
[0033] This embodiment provides a preparation method of a shape memory cyanate resin material resistant to gamma ray irradiation, comprising the following steps:
[0034] The first step: put the bisphenol A type cyanate monomer with a mass fraction of 60% in an oil bath at a temperature of 110°C, and after the cyanate monomer is completely dissolved, add a mass fraction of 20% Epoxy resin and mass fraction are 20% polyethylene glycol, carry out magnetic stirring 45min, make uniform cyanate ester precursor solution;
[0035] The second step: inject the cyanate ester precursor solution prepared in the first step into the preheated mold, the preheating temperature is 100°C, and place it in a blast oven for heating and curing. The curing process is that the temperature is Heated at 150°C for 2 hours, cured at 180°C for 2 hours, cured at 210°C for 3 hours, and the heating rate was 0.8°C / min to obtain a gamma-ray-resistant shape memory cyanate resin material.
Embodiment 3
[0037] This embodiment provides a preparation method of a shape memory cyanate resin material resistant to gamma ray irradiation, comprising the following steps:
[0038] The first step: put the bisphenol A type cyanate monomer with a mass fraction of 60% in an oil bath at a temperature of 100°C, and after the cyanate monomer is completely dissolved, add a mass fraction of 20% The polycaprolactone, the polyethylene oxide that the mass fraction is 10% and the polyethylene glycol that the mass fraction is 10%, carry out magnetic stirring 30min, make uniform cyanate ester precursor solution;
[0039] The second step: inject the cyanate ester precursor solution prepared in the first step into the preheated mold, the preheating temperature is 90°C, and place it in a blast oven for heating and curing. The curing process is that the temperature is Heated at 150°C for 2 hours, cured at 190°C for 3 hours, cured at 220°C for 3 hours, and the heating rate was 0.5°C / min to obtain a gamma-...
