Embodiment 1

[0034] (1) Synthesis of curing agent pentaerythritol tetramercaptopropionate epoxy resin prepolymer (PPTM) Add raw materials 3-mercaptopropionic acid (44.48g, 0.42mol) and pentaerythritol (15.13g, 0.11mol) respectively in a 250ml three-necked flask ), catalyst p-toluenesulfonic acid (0.90g, 0.0052mol), solvent toluene (90.06mL, 1.13mol) and a stir bar. Put the three-neck flask into the oil pan, set up the oil-water separator and the spherical condenser in sequence, control the temperature in the oil pan at 110°C, and reflux for 8 hours. When the reaction proceeds to about 2 hours, water will appear in the oil-water separator, and the liquid in the flask will change from cloudy to clear as the reaction progresses.

[0035] After the reaction, the solution was filtered through a funnel, and the filtered object was washed with alkali to neutrality, and then the washed solution was distilled under reduced pressure to obtain a colorless oily liquid. The solution was purified by ac...

Embodiment 2

[0040] Under the situation of not changing other proportions of Example 1, only change graphene to account for the percentage by weight of epoxy resin (128) to be 0%, component A and component B are mixed uniformly, join in the tetrafluoroethylene model plate Prepare a sample, and test the tensile properties of the prepared sample after fully curing.

Embodiment 3

[0042]Under the situation of not changing other proportions of Example 1, only changing graphene to account for epoxy resin (128) weight percentage is 5%, component A and component B are mixed uniformly, join in the tetrafluoroethylene model plate Prepare a sample, and test the tensile properties of the prepared sample after fully curing.

Abstract

The invention relates to a graphene / epoxy resin composite high polymer material. A prepared pentaerythritol tetramercaptopropionate epoxy resin prepolymer (PPTM) curing agent is used for curing, and the dosage of graphene, the dosage of the curing agent, the species of the curing agent are adjusted and optimally combined, so that the graphene / epoxy resin composite high polymer material is prepared. The high polymer material has the characteristics that the curing speed is fast, graphene is uniformly dispersed in a base material, the compatibility of the graphene and epoxy resin is good, the obtained material is good in mechanical property and low-cost, a preparation method is simple, environment pollution is less, and the like.

Description

technical field [0001] The invention belongs to the field of polymer material science, in particular to a graphene / epoxy resin composite polymer material. Background technique [0002] Epoxy resins are mainly used in coatings, civil engineering, material engineering, electrical and electronic industries and a small amount of adhesives. But in 2010, the application field of epoxy resin has undergone obvious changes, and its application in the field of adhesives has greatly increased and is becoming more and more extensive. At the same time, epoxy resin has a wide range of applications in electronics, electrical appliances, aerospace, coatings and other fields. Among them, modified coatings are the most widely used, and modified coatings show better performance and are favored by people. [0003] The development space of epoxy resin is huge, the market demand for epoxy resin is also increasing, and its performance requirements are gradually improving. High tensile strength, ...
