Abstract

一种能屏蔽核辐射的柔性复合材料。该柔性复合材料主要由铅纤维布、抗核辐射粉体、高分子材料组成。铅纤维布及抗核辐射粉既是复合材料的增强材料又是抗核辐射的功能材料;基体材料为高分子材料,也具有一定的抗核辐射功能。本发明包括:A.铅纤维布预先用偶联剂处理以降低表面张力,增强与高分子材料的相容性;B:抗核辐射粉体先同偶联剂混合均匀后再通过高速搅拌弥散到高分子材料中;C:将经过处理的铅纤维布与弥散有抗核辐射粉的高分子材料通过复合成型、脱模、养护而制得铅纤维基高分子复合材料。本发明的一种能屏蔽核辐射的柔性复合材料具有优异的抗核辐射性能,优秀的力学性能及稳定性,柔性好,可折叠、弯曲,质量较轻,价格低廉,可广泛应用于核辐射领域的防护。
Disclosed is a flexible composite material capable of shielding nuclear radiation. The flexible composite material mainly comprises lead fiber cloth, nuclear-radiation resistant powder and high-polymer material. The lead fiber cloth and the nuclear-radiation resistant powder can be reinforcing materials of composite and nuclear-radiation resistant function materials. The base material is the high-polymer material and has a certain function of nuclear radiation resistance. The flexible composite material is prepared by steps: A, the lead fiber cloth is treated by coupling agent in advance so as to reduce surface tension, and compatibility of the high-polymer material is improved; B, the nuclear-radiation resistant powder is uniformly mixed with the coupling agent firstly and is dispersed into the high-polymer material through high-speed stirring; and C, the lead fiber cloth treated and the high-polymer material dispersed with the nuclear radiation resistant powder are manufactured into a lead fiber based high-polymer composite material through composite forming, demoulding and maintaining. The flexible composite material capable of shielding nuclear radiation has the advantages of excellent nuclear radiation resistance, good mechanical performance, stability and flexibility, foldability, bendability, light weight and low cost and can be widely applied to protection of the field of nuclear radiation.
