Abstract

The invention provides gamma-irradiation-resistant modified resin. The gamma-irradiation-resistant modified resin is prepared by grafting and modifying epoxy resin with boric acid. The gamma-irradiation-resistant modified resin comprises epoxy resin, a curing agent, an accelerant, boric acid, a coupling agent and an organic solvent. The invention further provides a preparation method of the gamma-irradiation-resistant modified resin. The method comprises the following steps of: S1, carrying out boric acid graft modification on epoxy resin to obtain a modified resin glue solution; and S2, regulating the gelation time of the modified resin glue solution obtained in the step. The invention also provides a preparation process of a laminated board containing the gamma-irradiation-resistant modified resin, and application of the laminated board containing the gamma-irradiation-resistant modified resin. According to the gamma-irradiation-resistant modified resin, after the resin is subjectedto boric acid graft modification, the irradiation strength of the modified resin is obviously enhanced; and the laminated board prepared by combining the modified resin with basalt fiber cloth can ensure enough tensile strength and bending strength when the accumulated irradiation dose reaches 5X106Gy and is suitable for various environments with strong gamma strength.

Description

technical field [0001] The invention belongs to the field of fiber-reinforced composite materials, and relates to a gamma-irradiation-resistant modified resin, a preparation method thereof, a laminated board, a preparation process and application thereof. Background technique [0002] Basalt ore is formed due to the cooling of volcanic eruption magma. The main difference between the fiber composition drawn from the mineral raw material after high-temperature melting and glass fiber is that it contains 7-10% Fe 2 o 3 , which provides the possibility for the development of basalt fiber composite materials for specific purposes. [0003] With the gradual depletion of traditional fossil fuels, the development of efficient and clean new energy has always been a hot issue of scientific research workers. Among them, nuclear energy is considered by scientists to be the most promising clean energy in the future because of its huge energy development potential. focus. In the produc...
